The linear rule should look like this y=a*x+b
As the function graph goes through the (0,0) point, the equation 0=a*0+b <=> b=0 must be true.
Now we only need to find a, using one of the points given. With (-4, 16):
16=-4*a <=> a=16/-4 <=> a= -4
So the rule looks the following way:
f(x)= -4*x

Y=-4x
where x is the first value and y the second value in each pair.

Find the scale factor of the similar shapes below.
timofeeve [1]

Answer:

x=12 and the scale factor is 1.5

Step-by-step explanation:

From D' to F' is 7.5 and from D to F is 5cm the difference is 2.5. From F' to E' is x and from F to E is 8. This is just understanding what you can see. You find x by figuring out the ratio from 5 to 7.5 is and 8 to x or vise versa.  It depends which way you are going. I think you are going from E,D,F to E',D',F'. So from 5cm to 7.5 cm. This is 1.5 because you are dividing 7.5/5. If you needed to find x, it would be 12.

I could use a little help with this one. i'm rusty.<br> -3(x+2)-7 = 5x + 7
Pie

Answer:

-3(x+2)-7 = 5x + 7

-3x - 6 - 7 = 5x + 7

-3x - 13 = 5x + 7

-20 = 8x

x = -2.5

Question 57 need help
prisoha [69]
Okay so first we need to find the height ofn one hay barrel. To do this we must use the equations v= h×w×l

We already know 3 out of the 4 variables in the equations, in this case we are given the volume so we must work backwards.

The equation will look like this:
10 \frac{2}{3}    = h \times (1  \frac{1}{3} ) \times 4
First we must mulitpy 4 and 1 1/3 to get 16/3. The equation will now look like:
10 \frac{2}{3}  = h \times  \frac{16}{3}
Next divide 16/3 from h then from 10 2/3 to get :
2 = h
The height is 2ft. Finally multiply 2 by the number of hay barrels (8) placed upon each other becuase we're finding the height and you will get your answer of 16 ft in height.
