In this question, 5x squared +7, which one is the constant?
Answer:
7 would be the constant
Step-by-step explanation:
Constants are the values in an equation that never changed or are isolated. For instance, 5 would not be a constant because of the variable (x) being multiplied. Though, if it were 5+x square +7, 5 and 7 would be the constants.

What is the area of the shaded region?
Answer
157.44
Step-by-step explanation:
To find area of triangle you have to multiply base times height then divided by 1/2. 19.2 cm being your height x 16.4 cm being your base, then divide by 2.
Answer:
area of the triangle = ½×base×height
½×19.2×16.4 = 157.44
so, the area of the triangle is 157.44cm³

a. x = 15, y = 40
b. x = 30, y = 40
c. x = 15, y = 20
d. x = 30, y = 20
Answer: a. x = 15, y = 40
Step-by-step explanation:
So we already know that ΔABC and ΔFDE are congruent, which means their angles are equal. Based on this information, we could note that:
∠A = ∠F
∠C = ∠E
∠B = ∠D
Since we already know the measurement of ∠B, we could then conclude that ∠D, or y, is equal to 40°. This leaves us with two possible answers, a or b.
In order to find the value of x, we need to know the measurement of ∠F. And in order to find ∠F, we need to find the measurement of ∠A. We already know that the angles in a triangle sums up to 180°. So we would start as the following.
∠A + ∠B + ∠C = 180
We first substitute the known measurements.
∠A + 40 + 110 = 180
We then add up 40 with 110.
∠A + 150 = 180
We finally substract 150 on both sides of the equation. This gives us the measurement of ∠A.
∠A = 30°
Now that we know ∠A, we could start finding the value of x. So we already know this:
∠A = ∠F
We first substitute each angle with their known measurements.
30 = 2x
We now divide both sides by two. This gives the value of x.
x = 15

Parallel Lines Practice NO LINKS PLEASE and please explain this for me so i can understand
Answer:
120
Step-by-step explanation:
As those two lines are parallel, we can express and equation:
[tex](6x + 18) + (4x - 8) = 180[/tex]
[tex]6x + 4x = 180 - 18 + 8[/tex]
[tex]10x = 170[/tex]
[tex]x = 17[/tex]
[tex]6x + 18 = 102 + 18 = 120[/tex]

which of the following straight line is parallel to y = 7 - 2x?
Answer:
Whichever line has a slope of -2
Step-by-step explanation:
rewrite in slope intercept
y=mx+b where m=slope
y=-2x+7
-2 is the slope of the original line
a parallel line will never intersect
the parallel line must have the same slope

Answer:
the answer is the third one k > - 5
Answer/Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
[tex]\frac{1}{4}k+\frac{-3}{4}>-2[/tex]
Step 2: Add 3/4 to both sides.
[tex]\frac{1}{4}k+\frac{-3}{4}+\frac{3}{4}>-2+\frac{3}{4}[/tex]
[tex]\frac{1}{4}k>\frac{-5}{4}[/tex]
Step 3: Multiply both sides by 4.
[tex]4*\frac{1}{4}k>4*\frac{-5}{4}[/tex]
K > -5
So according to this the value of k has to be greater than -5
You can check your answer by substituting the values in for k.
You can use a calculator..
[tex]\frac{-10-3}{4} >-2[/tex]
[tex]\frac{-7-3}{4} >-2[/tex]
[tex]\frac{-1-3}{4} >-2[/tex]

Emily has 20 chocolate chip cookies in 48 sugar cookies she wants to make baskets with the same number of cookies in each basket what is the greatest number of baskets she can make
Answer: Take your pick, Emily.
Step-by-step explanation:
1) Assuming Emily wants both Chocolate Chip(CC) and Sugar Cookies(SC) in each basket, she could make 20 baskets having 1 CC and 2 SC in each basket. That would leave 8 SC (48-40) without any matching CC.
2) If Emily doesn't care about the makeup of each basket (e.g., some baskets may have any combination of cookies), she has a total of (20 + 48) or 68 cookies. She has the following choices:
1 cookie each: 68 baskets
2 cookies each: 34 baskets
3 cookies each: 22 baskets with 2 cookies left over
And so forth.
Unless Emily was given some other condition (e.g., a minimum of 5 cookies/basket), there are many possible answers.

Theo used to drive 60 miles to work each day. His new home is now 20 miles away
from his job. What is the percent of
decrease in the distance Theo travels to
work? Round to the nearest tenth if
necessary.
Answer:
66.6% decrease in distance
Rounded 67%
He is traveling 1/3 of what he used to travel
Step-by-step explanation:
The percentage of decrease in the distance Theo travels to work is 66.7%.
Used concept of percentage;
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating the hundredth part of any quantity is called a percentage.
Given that;
Theo used to drive 60 miles to work each day.
And, His new home is now 20 miles away from his job.
Hence the percentage of decrease in the distance Theo travels to work is,
P = (60 - 20)/60 x 100
P = 40/60 x 100
P = 66.7%
So, The percentage of decrease in the distance Theo travels to work is 66.7%.
