Write and solve an equation using the descriptions below.
The sum of 4 and three times a number is 19
Answer:
5
Step-by-step explanation:
Let x be that number.
4 + 3 × x = 19
4 + 3x = 19
Add -4 on both sides.
4 + 3x - 4 = 19 - 4
3x = 15
Divide both sides by 3.
(3x)/3 = 15/3
x = 5
Answer:
4+3x=19 so, x=5
19-4= 15, 15/3=5 or 5*3=15, 19-15=4.

Answer:
[tex]f(x) = 3x^2[/tex] and [tex]g(x) = x + 2[/tex]
Step-by-step explanation:
Given
[tex]h(x) = 3(x+2)^2[/tex]
[tex]h(x) = (fog)(x)[/tex]
Required
Find possible expressions for f(x) and g(x)
[tex]h(x) = (fog)(x)[/tex]
This can be rewritten as:
[tex]h(x) = f(g(x))[/tex]
Recall that [tex]h(x) = 3(x+2)^2[/tex]
So;
[tex]h(x) = f(g(x)) = 3(x+2)^2[/tex]
[tex]f(g(x)) = 3(x+2)^2[/tex]
By comparison, the expression in bracket represents g(x);
Hence;
[tex]g(x) = x + 2[/tex]
Replace g(x) with x
[tex]f(x) = 3(x)^2[/tex]
[tex]f(x) = 3x^2[/tex]
Hence, the possible expressions of f(x) and g(x) are:
[tex]f(x) = 3x^2[/tex] and [tex]g(x) = x + 2[/tex]
−4(w+1)=−24 SIMPLIFY PLEASE HELP ASAP
Answer:
w = 5
Step-by-step explanation:
Expand brackets.
-4w - 4 = -24
Add 4 on both sides.
-4w = -20
Divide both sides by -4.
w = 5
Answer:
w=5
Step-by-step explanation:
First, you do -4 times w and -4 times 1, which equals -4w+-4.
Then, you take -4 to the other side and it becomes -24+4=-20.
Now, you have -4w= -20
Lastly, you you divide -20/-4= 5.
w=5

Trying to find the missing segment to the triangle in the attached image.
Answer:
36 units.
Step-by-step explanation:
we will use concept of basic proportionality theorem,
it states that , when a line is drawn parallel to one side of the triangle and intersect the other two sides then the two sides are divided in the same ratio.
Example:
In a triangle ABC
If DE is parallel to BC
D is a point on line AB and E is point on AC, then
by basic proportionality theorem)
AD/DB = AE/EC
_____________________________________
in the problem given one side has a parallel line drawn to it
Hence we can use basic proportionality theorem in it
20/30 = 24/?
2/3 = 24/?
=> ? = 24*3/2 = 36
Hence, missing segment value is 36 units.

Determine the slope of the lines parallel and perpendicular to -4x+3y=11
Answer:
parallel = 4/3
perpendicular =-3/4
Step-by-step explanation:
Solve for y
-4x+3y=11
Add 4x to each side
3y = 4x+11
Divide by 3
y = 4/3 x +11/3
This is in the form y = mx+b where m is the slope
m =4/3
The parallel line has the same slope
parallel slope is 4/3
The perpendicular line has a negative reciprocal slope
m = -(1 /4/3) = - 3/4
Answer:
[tex]\frac{4}{3}[/tex] and - [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
- 4x + 3y = 11 ( add 4x to both sides )
3y = 4x + 11 ( divide all terms by 3 )
y = [tex]\frac{4}{3}[/tex] x + [tex]\frac{11}{3}[/tex] ← in slope- intercept form
with slope m = [tex]\frac{4}{3}[/tex]
Parallel lines have equal slopes, thus
slope of parallel line = [tex]\frac{4}{3}[/tex]
Give a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{4}{3} }[/tex] = - [tex]\frac{3}{4}[/tex]
describe the cross-section of the rectangular prism

rectangle
triangle
hexagon
Answer:
The cross-section of the rectangular prism is a:
rectangleStep-by-step explanation:
When you take a cross-section of a rectangular prism, regularly you will obtain a rectangle because this was the base or the two-dimension figure that was used to form the three-dimension figure, in this case, the rectangular prism, the form of obtaining other figure is using how reference the square face, in that case, the cross-section would be a square, this happens because the cross-section is bind with the reference face. Possibly you think the cross-section in the figure doesn´t appear a rectangle, this happens by the perspective because we are looking at the rectangular prism with an inclination of 45°, but if the inclination was 90°, you would see a blue rectangle.

Which distribution is positively skewed?
Answer:
D
Step-by-step explanation:
not positive but i think it would be D
Option C is the distributions are positively skewed.
Since, A distribution that is positively skewed would have the following highlights:
More points on the left, if represented on a dot plot
Tall bars on the left, if represented on a histogram
Whisker on the left, if represented on a box plot
The above means that none of the distributions are positively skewed.
This is so because:
A is negatively skewed because the whisker is at the right
B and C are symmetrical because there are tall bars at the middle
D is positively skewed because the whisker is at the left.
Hence, Option D is the distributions are positively skewed.

Write all the names of the quadrilateral shown.
Answer:
see explanations
Step-by-step explanation:
The given figure has four equal sides, and all adjacent sides are perpendicular to each other.
Quadrilateral is a any figure with four sides.
Particular quadrilaterals have specific names.
A square is a quadrilateral with equal sides, each perpendicular to the adjacent side, as shown in the figure.
A rectangle is a quadrilateral of which all sides are perpendicular to the adjacents. Therefore opposite sides are equal. Adjacent sides MAY or MAY NOT be equal. Therefore a square is also a rectangle.
A rhombus is a quadrilateral of which all four sides are equal, but adjacent sides MAY or MAY NOT be perpendicular. Therefore a square is also a rhombus.
A trapezoid (or trapezium, depending on which side of the atlantic you live) is a quadrilateral with AT LEAST one pair of parallel sides. The other pair may or may not be equal, may or may not be parallel. Therefore a square is also a trapezoid (trapezium).
A quadrilateral is any plane figure with four sides, which may or may not be parallel, may or may not be equal, and adjacent sides may or may not be perpendicular. Therefore a square is also a quadrilateral.
So the given figure could be given all six possible names indicated in bold. However, the name square is most specific.
Consider the graph of the linear function h(x) = –6 + h(x) equals negative 6 plus StartFraction 2 Over 3 EndFraction x. x. Which quadrant will the graph not go through and why?
Answer:
2nd quadrant.
Step-by-step explanation:
The given function is
[tex]h(x)=-6+\dfrac{2}{3}x[/tex]
We need to find the quadrant from which the graph of function is not passing.
At x=0,
[tex]h(0)=-6+\dfrac{2}{3}(0)=-6[/tex]
So, y-intercept is (0,-6).
At h(x)=0,
[tex]0=-6+\dfrac{2}{3}x[/tex]
[tex]6=\dfrac{2}{3}x[/tex]
[tex]18=2x[/tex]
[tex]9=x[/tex]
So, x-intercept is (9,0).
It means the graph intersect negative side of y-axis and positive side of x-axis. When we join these two points, we get the graph is not passing through the 2nd quadrant.
Therefore, the required quadrant is 2nd quadrant.

John cut a paper square with a perimeter of 18 inches into two rectangles. The perimeter of one of the rectangles is 10 inches. What is the perimeter of the second rectangle?
Answer:
17 inches
Step-by-step explanation:
The original square had sides of 4.5 (18/4)
To get a perimeter of 10, we know that two sides would already equal 9 (4.5+4.5). That means we only have 1 inch for the other two sides, so they are each 1/2 inch.
That leaves the second rectangle with a length and width of 4.5 and 4.

To determine the surface area and volume of a cone, the three values you need are the slant height, altitude, and Question 3 options: A) arc length. B) circumference. C) radius. D) diameter.
Answer:
radius is the other quantity needed, which appears listed as option C in the list of possible answers.
Step-by-step explanation:
Recall that the volume of a cone is given by the formula:
[tex]Vol=\frac{1}{3} B\,*\, H[/tex]
where B is the area of the base:
[tex]B=\pi\,R^2[/tex]
with R being the cone's radius at the base, and H the cone's height.
The formula for the surface area of the cone also needs the size of the radius.
Therefore, the radius is the other needed quantity.
Answer:
C) Radius.
Step-by-step explanation:
When looking at a shape like this is is crucial to know the circumference because Area is L*W*H In order to determine your width you will need the Radius.

Find the value of a2 and square root b, when a=12 and b=9.
Answer:
147
Step-by-step explanation:
We want to find the value of a² + √b, so let's plug in 12 for a and 9 for b:
a² + √b
12² + √9
The square root of 9 is 3 because 3 * 3 = 9, while the square of 12 is 144 because 12 * 12 = 144.
144 + 3 = 147
The answer is thus 147.

In OD, AB = CB and marc CE - 52. Find mZBCE. (See picture)
Answer:
A. 109
Step-by-step explanation:
We know that since AB = CB, then ΔABC is isosceles.
Since AC, one of the sides of ΔABC, is on the diameter of circle D, by definition, we know that ΔABC is also a right triangle. Thus, if ΔABC is an isosceles right triangle, then ∠BAC = ∠BCA = 45°.
Draw a line connecting D to B so that we now have isosceles triangle BDC. Since arc BC is 52°, by definition of central angles, ∠BDC is also equal to 52°. Then, ∠DBC = ∠DCB = (180 - 52)/2 = 64°.
∠BCE = ∠DCB + ∠BCA
∠BCE = 64 + 45 = 109°
The answer is thus A.
