Answer:
0=18
Step-by-step explanation:
not simplified.
Answer:
There is no answer.
Step-by-step explanation:
-2(11 - 12x) = -4(1-6x)
First you need to simplify the equation, using distributive property.
Distribute -2 to the numbers within the parentheses.
-2*11 = -22
-2*-12x =24x
= 24x - 22
Then distribute -4 among 1 and -6.
-4*1 =-4
-4*-6x = +24x
= 24x - 4
And because
24x - 22 does NOT equal 24x - 4
There is no answer because they are not equivalent, making the equation itself false/untrue.
Use point-slope form to find the equation of the line with a slope of -3 that passes through the point (-1,0)? Express your answer in slope-intercept form.
Answer:
y = -3x - 3
Step-by-step explanation:
y = -3x + b
0 = -3(-1) + b
0 = 3 + b
-3 = b
y = -3x - 3
6. Lines C and D below are cut by transversal, t. Which of
the following is true about the angles formed?
Answer:
m∠8 = m∠2, option G
Step-by-step explanation:
Angles 8 and 2 are alternate interior angles, which means they are equal. Thus, the answer is option G, m∠8 = m∠2
A rectangle has a length of 4 millimeters and an area of square 116 millimeters. What is the width? What is the perimeter?
Answer:
Width = 29mmPerimeter = 66mmStep-by-step explanation:
The area of a rectangle can be calculated by the formula:
= Length * Width
As we have the length and the area, we can make the width the subject of the formula to solve for it:
116 = 4 * width
Width = 116/4
= 29 mm
Perimeter is:
= Length + Length + Width + Width
= 4 + 4 + 29 + 29
= 66 mm

Answer:
x = 7, x = 5
Step-by-step explanation:
Given 2 intersecting chords, then
The product of the parts of one chord is equal to the product of the parts of the other chord.
(1)
27x = 9 × 21 = 189 ( divide both sides by 27 )
x = 7
(2)
12(3x - 5) = 120 ( divide both sides by 12 )
3x - 5 = 10 ( add 5 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5

Step-by-step explanation:
Aiden bought 2 iPads for a total of $480. At this rate, what is the cost of 3 iPads?
Answer:
The cost of three would be $720.
Step-by-step explanation:
First you need to divide 480 by 2 which gives you 240. 240 is the cost of one iPad so 240 times 3 is 720.
Answer:
$720.Step-by-step explanation:
Karleebordelon6 has a wonderful answer, but I will provide a slightly different approach.
This can be solved by using proportions.
Take a look:
[tex]\frac{2 (ipads)}{480 (dollars)} =\frac{3 (ipads)}{x}[/tex]
After setting up the proportion, we can cross multiply.
[tex]480 * 3 = 1440\\[/tex]
[tex]2 *x = 2x[/tex]
Lastly, divide both products.
[tex]2x = 1440[/tex]
[tex]1440/2 = 720[/tex]
Therefore, the total cost of 3 iPads is $720.
In other words, x = 720.
[tex]\frac{2(ipads)}{480(dollars)} =\frac{3( ipads)}{720(dollars)}[/tex]
What is m
A- 28
B- 31
C- 62
D- 90
E- 118
Answer:
D. 90
Step-by-step explanation:
If a triangle is inscribed inside of a circle, using the diameter as the hypotenuse, then the opposite angle of the hypotenuse is equal to 90 °
Because ΔABC is inscribed inside of the circle using the diameter it is a right triangle.
∠ABC is the angle opposite of the diameter therefore ∠ABC = 90°

What is the area, in square centimeters, of the trapezoid below?
11.7 cm
5.5 cm
6.5 cm
Answer:
50.05 cm^2
Step-by-step explanation:
Ok so first lets find the area of the rectangle before finding the attached triangle. You have to imagine a line separating this shape into a triangle and rectangle.
The rectangle's size is 6.5x5.5=35.75 cm^2
The rectangle's size is 11.7-6.5 to get the base length, which is 5.2
The height is 5.5
So it's 5.2*5.5/2=14.3 cm^2
14.3+35.75=50.05 cm^2
Write an equation to represent function A
Answer:
y = 312x + 2
Step-by-step explanation:
According to y = mx + b, m stands for slope and b stands for y-intercept. Let us find the y-intercept. To find the y-intercept, the x should be zero in (x, y).
(x, y)
(0, 2) ---> y-intercept (b)
Now that we have found the y-intercept, we will now find the slope by using its formula.
Slope formula:-
m = y2 - y1 / x2 - x1
Pick two random (x, y). I will pick the first and last pairs.
(0, 2) and (4, 1250)
Now plug these two pairs in the formula.
m = y2 - y1 / x2 - x1
m = 1250 - 2 / 4 - 0
m = 1248 / 4
m = 312
This means that the slope (m) is 312. Now put that in y = mx + b form.
y = mx + b
y = 312x + 2
Both of the forms are the same. Hope this helps, thank you :) !!

A nutritionist collects data from 25 popular breakfast cereals. For each cereal, the number of calories per serving is
plotted on the x-axis against the number of milligrams of sodium on the y-axis. The value of , for the resulting
scatterplot is 0.83.
How would the value of the correlation coefficient change if sodium was plotted on the x-axis
and calories plotted on the y-axis?
A.The value of r would increase
B.The value of r would not change
C.The value of r would change to -0 83.
D.The value of r could increase or decrease, depending of the strength of the new relationship.
Answer:
B) The value of r would not change
Step-by-step explanation:
If there's a positive association between sodium and calories, that's like saying there's a positive association between calories and sodium. Therefore, the value of r would not change because both variables are still increasing with each other.
