Answer:
f(x)=-2x-4
Step-by-step explanation:
First of all, I want to say that I'm a 5th grade kid, and I'm studying linear functions in eight grade. The equation is f(x) = mx + b. The b is y intercept. Since the y is -1, we know that f(x)=mx+-1, or f(x)=mx-1. Then, we look that the x. It's 2. Then, substitute 2 for m. F(x) = 2x-1. I'm gonna do the other ones. f(x)=4x-5, f(x) = 6x-9. We know that the x is substracting 2. The y is subtracting 4. So the rule is f(x) = -2x-4

Oak Street and Elm Street run parallel to each other. When Main Street intersects them, it forms exterior ∠8, measuring 60°. What is the measure of ∠2?
Answers
Answer:
Angles 8 and 2 are alternate exterior angles, meaning they are on the same side of the transversal that runs through it but are on the outside.
Alternate exterior angles are supplementary, which means they both have a sum of 180°.
So if you were to find the supplement of 60°, it would be 120°.
This is because;
x + 60 = 180
-60 -60
x = 120, so ∠2 = 120°

There is a total of 27 quarters stacked in four piles. The first pile has 5 fewer than the second pile. The second pile has 4 more than the third pile. The fourth pile has three times as many as the second pile. How many quarters are in the fourth pile?
Answers
Answer: 18 quarters
Step-by-step explanation:
second pile = x
first pile = x - 5
third pile = x - 4
fourth pile = 3x
total amount of quaters = 27
x + x - 5 + x - 4 + 3x = 27
6x = 36 x = 6
fourth pile = 3(6) = 18
Solution:
Note that:
27 quarters = 4 piles = 1st pile + 2nd pile + 3rd pile + 4th pile1st pile = 2nd pile - 5 = 3rd pile - 12nd pile = 1st pile + 5 = 3rd pile + 43rd pile = 1st pile - 1 = 2nd pile - 44th pile = 3(2nd pile)This means that...
27 quarters = (2nd pile - 5) + (2nd pile) + (2nd pile - 4) + 3(2nd pile)First, let's find the number of quarters in 2nd pile.
Open the brackets.
27 quarters = (2nd pile - 5) + (2nd pile) + (2nd pile - 4) + 3(2nd pile)=> 27 quarters = 2nd pile - 5 + 2nd pile + 2nd pile - 4 + 3(2nd pile)Combine like terms.
=> 27 quarters = (-5 - 4) + 6(2nd pile)Simplify the RHS.
27 quarters = -9 + 6(2nd pile)Add 9 both sides.
27 + 9 = 6(2nd pile)=> 36 quarters = 6(2nd pile)Divide 6 both sides.
=> 6 quarters = 2nd pileNow, substitute the number of quarters in 2nd pile in it's equation.
4th pile = 3(2nd pile)=> 4th pile = 3(6)=> 4th pile = 18 quarters.Rewrite the following expressions using additive inverses, then slove.

Estimate the area of each figure. Each square represents 1 square inch (PLEASE HELP)
Answers
Answer:
1. 13
2. 3.14 (estimation: 3)
3. 14
Step-by-step explanation:
So, if each square represents 1 square inch, then you know that the big square equals 5x5 square inches, or 25 square inches. So, for the first problem, you can subtract 25 by 12, because we know that the white squares sum to 12. For question 2, the formula to find the area of a circle is pie*radius^2, so we get 3.14*1^2, which is 3.14. For number 3, we can simply count the shaded squares, and you get 14.

Answer:
area is just multipling the base and the height.
ˆ2 means squared
Step-by-step explanation:
1) 7.6 is the height and 11 the base, so the area would be 83.6cmˆ2
2) there is a triangle but to find the area we divide it into 2 parts. first lets get the measurments settled, we can see that the height is 4ft, and the triangle on the left we can see that the base is the same size as the height, look at the image i attatched if you dont understand how i am explaining it. but we know that the total size of the base is 12, right? well if we subtract the 4 ft from the left triangle we are left that the right triangle has the size of 8ft for base and 4ft for height, if we multiply we have 32ftˆ2 but its a triangle so remember we have to divide this answer by 2, giving us the first area of 16ftˆ2. now we move onto the left triangle, 4 from the height x 4 from the base gives us 16cmˆ2 same as before we divide by two which gives us for the second area 8ftˆ2, now we add both areas we obtained, giving us the area for the whole figure which is, 24ftˆ2
3) for this one we will divide it into 3 parts, look at the image attached, for the steps
4) Ahhh! fractions, dont be nervous these are easy peasy, we know the base is 4in and the height is 3 1/2in. lets convert the fraction into decimals so its easier, so now we have 3.5 as height and 4 as base, we multiplay them which will give us 14inˆ2 since its a triangle we have to divide by 2! our answer will be 7inˆ2
For 5 and 6 look at the image :]

128°

BTW THERE IS NO 132!
Answers
180 degrees is the total “degree value” of a triangle
90 degrees is given because the triangle is a right triangle
38 degrees is given as angle A
180 - 90 - 38 = 52 degrees
Kind note:
I am sure that the triangle you meant was in the image attached. I will find n in the image I attached.
Solution:
We know that:
∠B = 90°∠A = 38°Sum of interior angles of a triangle = 180°Step-1: Find ∠C.
∠A + ∠B + ∠C = 180°=> 38 + 90 + ∠C = 180°=> ∠C + 128 = 180°=> ∠C = 180 - 128 = 52Step-2: Find n.
52 and n are a linear pair.
52 + n = 180=> n = 180 - 52=> n = 128Karen and Kevin collect coins. Karen has x coins. Kevin has 5 coins fewer than two times the number of coins Karen has. Write and simplify an expression for the total number of coins Karen and Kevin have.
