On a piece of paper, graph y < 3/4x + 2. Then determine which answer choiceu
matches the graph you drew.
Answer:
Graph A is the answer
Step-by-step explanation:
Graph A is correct.
We have an inequality -
[tex]y < \frac{3x}{4}+2[/tex]
We have to graph this inequality and select the correct option.
What is inequality?Inequality in mathematics is a relation that is used to compare two or more algebraic expressions.
We have in our question an inequality as -
[tex]y < \frac{3x}{4}+2[/tex]
Follow the following steps to reach the graph -
STEP 1 ->
Replace the ' < ' sign with ' = ' sign and plot the graph of the equation formed - [tex]y = \frac{3x}{4}+2[/tex]
which is same as y = mx + c.
On comparing : m = [tex]\frac{3}{4}[/tex] and c =2.
Therefore, this line intersects the y - axis at the point (0, 2).
STEP 2 ->
Since the line does not pass through (0,0) we can consider it as our test point. Substituting x = y = 0 in the inequality, we get -
0 < 0 + 2
0 < 2, which is true.
We will shade the area in which (0,0) lies.
STEP 3 ->
Since the inequality is a strict inequality, the line will be a dotted line.
Hence, Graph A is correct.

Assume a fair deck of playing cards. Find the probability of drawing a 10, replacing it and drawing an ace.
Answer:
There are 52 cards in a deck. The total number of outcomes possible when picking 2 cards and replacing them is 52 * 52 = 2704.
There are 4 10s and 4 aces so the total number of successful outcomes = 4 * 4 = 16.
Probability = 16 / 2704 = 1 / 169

Which of these graphs represents a function?
Answer:
the top right
Step-by-step explanation:
Choose two of the angles on ∆ABC, and locate the line segment between them. Draw a new line segment,DE , parallel to the line segment you located on ∆ABC. You can draw of any length and place it anywhere on the coordinate plane, but not on top of ∆ABC. From points D and E, create an angle of the same size as the angles you chose on ∆ABC. Then draw a ray from D and a ray from E through the angles such that the rays intersect. You should now have two angles that are congruent to the angles you chose on ∆ABC. Label the point of intersection of the two rays F, and draw ∆DEF by creating a polygon through points D, E, and F.
Answer:
The two triangles are attached below.
Step-by-step explanation:
Let the ∆ABC be an isosceles right angled triangle.

A polynomial has been factored below, but some constants are missing.
Answer:
From the information in the problem, the value of a is 2, the value of b is 2, and the value of c is -6.
Step-by-step explanation:
The first thing we have to do is factor the equation in order to find the value of a, b, and c.
2x³ - 8x² - 24x
Find a common factor that can be easily divisible among all the terms. This common factor is 2x. Factor the equation.
2x(x² - 4x - 12)
Now, we have to factor out the equation in the parentheses. we do this by multiplying the first term by the last term first. Since there is no coefficient number for x², then we assume this number to be 1.
1 × -12 = -12
Now, we have to find two numbers that multiply to get -12 but add together to get -4. These numbers are 2 and -6. Let's plug these numbers into the equation.
2x(x² + 2x - 6x - 12)
Group the first and second terms together and group together the third and last term together in the parentheses.
2x((x² + 2x) + (-6x - 12))
Factor the equation in parentheses.
2x(x + 2)(x - 6)
So, the value of a is 2, the value of b is 2, and the value of c is -6.

Two triangles can be formed with the given information. Use the Law of Sines to solve the triangles. A = 56°, a = 16, b = 17 (5 points)
Answer:
B = 61.75°
Step-by-step explanation:
The formula for the Law of Sines is given as:
a/ sin A = b/ sin B
In the question, we are given the following values
A = 56°, a = 16, b = 17
We are to solve for B
Hence,
16/ sin 56° = 17/sin B
Cross Multiply
sin B × 16 = sin 56° × 17
sin B = sin 56° × 17/16
sin B = 0.88
B = arc sin(0.88)
B = 61.74536°
Approximately B = 61.75°
1/4 of a pipe is white , 1/2 part of the remaining is blue. If the remaining part is black and the length of this black part is 5 1/4cm, find the length of the pipe.
Answer: 14 cm
Step-by-step explanation:
First take out 1/4 of the pipe, the portion that is white. Then, half of three quarters of the pipe is blue. 1/2 of 3/4 is 3/8. 3/8(blue) + 2/8(white) = 5/8. Thus, 3/8 of the pipe is black. Thus, take 5.25(The length of the black portion) and multiply it by 8/3(reciprocal of 3/8) to get 14.

How can you find f(3) if f(x) = -2x2 – 4?
Answer: f(3)=-20
Step-by-step explanation:
If you look at f(x) and f(3), you can see that 3 is in place of x. That means when x=3, what is f(x). You plug in x=3 into f(x) and solve.
f(3)=-2(3)²-2
f(3)=-2(9)-2
f(3)=-18-2
f(3)=-20
Answer:
-20
Step-by-step explanation:
Using addition rules, show how to add the two real numbers. 7 +(-14)

Find x value for the point that splits segment CD in half if point C is located at (−2, 4) and point D is located at (3, 7). (5 points) 5.5 5 0.5 3
Answer:
0.5
Step-by-step explanation:
To find the midpoint, add the x values and y values respectively. Then divide the results by 2. So, the midpoint of CD will be (0.5,5.5). The x value is 0.5.
Hey there! :)
Answer:
0.5.
Step-by-step explanation:
Use the midpoint formula to solve for the coordinates:
midpoint = [tex]({\frac{x_{1}+x_{2}}{2} },{\frac{y_{1}+y_{2}}{2} } )[/tex]
Plug in the points for C and D:
[tex]({\frac{-2+3}{2} },{\frac{4+7}{2} } )[/tex]
Simplify:
[tex]({\frac{1}{2} },{\frac{11}{2} } )[/tex] These are the coordinates for the midpoint.
The x-value of the coordinate is 1/2, or 0.5.

B. X= 3 V13
C. X=-3 v15
D. X = +3
SUB
Answer:
x = 3 + sqrt(13) or x = 3 - sqrt(13) or B)
Step-by-step explanation:
Solve for x:
x^2 - 6 x - 4 = 0
Hint: | Solve the quadratic equation by completing the square.
Add 4 to both sides:
x^2 - 6 x = 4
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 9 to both sides:
x^2 - 6 x + 9 = 13
Hint: | Factor the left hand side.
Write the left hand side as a square:
(x - 3)^2 = 13
Hint: | Eliminate the exponent on the left hand side.
Take the square root of both sides:
x - 3 = sqrt(13) or x - 3 = -sqrt(13)
Hint: | Look at the first equation: Solve for x.
Add 3 to both sides:
x = 3 + sqrt(13) or x - 3 = -sqrt(13)
Hint: | Look at the second equation: Solve for x.
Add 3 to both sides:
Answer: x = 3 + sqrt(13) or x = 3 - sqrt(13)
