Step-by-step explanation:

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 :]

Answer:

y = 2Kx -5

Step-by-step explanation:

make karen's coins=x and Kevin's coins=y

the information given tells us that Kevin has 5 less coins than double Karen's. This means that to find Kevin's amount of coins, you must double Karen's coins (2x) and then subtract 5 (-5). Hope this helps!

y = 2x -5

Answer:

y=-2x+3

Step-by-step explanation:

m = slope = y/x = -4/2 = -2

b = y intercept = 3

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

Answer:

(5,-3)

Step-by-step explanation:

if you go from point A to point M, you go right 5 units and up 0.5 units. So if you do the same thing from point M and go right 5 units and up 0.5 units, you get (5,-3)

hope this helped! :)

Kind note:

I am sure that the triangle you meant was in the image attached. I will find n in the image I attached.

Answer:

u = 10 i think

Step-by-step explanation:

-14/ -7/5 = u

u = -14 (5/-7)

u = -70/-7

u = 10

-7/5 (10) = -14 ?

-70/ 5 = -14 ?

-14 = -14

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.

x = 0 is a vertical line.

If a point is reflected across a vertical line, x-value becomes the distance from the reflection line and the sign changes most likely.

Thus if (-4,3) is reflected across a vertical line, its sign change and it becomes (4,3)

Answer:

In order from largest to smallest:

quart, pint, cup

Step-by-step explanation:

A quart is the same thing as 4 cups or 2 pints. If we still need more liquid we can switch to using gallons. However, a gallon is the same as 16 cups or 8 pints or 4 quarts.
