Instead of subtracting 6 from 12 then dividing they added 6 to 12 & ended up with 18. 18 by 2 is 9.

Have you learned slope yet? Pick two points from the graph and do x-y on the top and x-y on the bottom. That would give you your slope then you can graph it. For example (-2,-1) (-1,1)
-2-(-1)
-1-1
Then that would give you -1/-2 so technically -1/2<< this is what you graph

Clara writes the equation (x – 13)(x + 8) = 196 to solve for the missing side length of a triangle represented by the factor x +
Kitty [74]
<span>(x – 13)(x + 8) = 196
</span>x * x + x * 8 - 13 * x - 13 * 8 = 196
x² + 8x - 13x - 104 = 196
x² - 5x - 104 - 196 = 0
x² - 5x - 300 = 0

The missing side length is 28

In at least one complete sentence, explain why the graph of y = 2x+1 does not go through
Crazy boy [7]

Answer:

The graph of y = 2x+1 will never go through the point (2,3) because the graph is a linear function which means it goes in a straight line. Knowing this, when y = 3, x = 5 this means that the function will never hit (2,3)

Use the arithmetic progression formula to find the sum of integers from 75 to 100.75,76,77....99,100.​
Sophie [7]

Answer:

The sum is 2275

Step-by-step explanation:

Given

75,76,77....99,100

Required

The sum

Using arithmetic progression, we have:

S_n = \frac{n}{2}(T_1 + T_n)

Where:

T_1 = 75 --- first term

T_n = 100 --- last term

n = T_n - T_1 + 1

n = 100 - 75 + 1 = 26

So, we have:

S_n = \frac{n}{2}(T_1 + T_n)

S_n = \frac{26}{2}*(75 + 100)

S_n = 13*175

S_n = 2275
