The sum of -7 times a number and 8 times the sum of the number and 1 is the same as the number minus 7
Vladimir79 [104]

Answer:

8 = -7

This statement is false.

Step-by-step explanation:

The number will be represented by x

-7x + 8(x + 1) = x - 7

8 * x = 8x

8 * 1 = 8

-7x + 8x + 8 = x - 7

Add like terms

-7x + 8x = x

x + 8 = x - 7

-x         -x

8 = -7

This statement is false.

Please help! I'm getting timed.
Molodets [167]
Hi there! The answer is A.

t = 2(s + 2)
To get a proper idea of the type of function this formula represents we work out the parenthesis.

Working out the parenthesis can for instance be done using rainbow technique.
t = 2s + 4

We can now see sinilarities between this function an the general function of a line in slope intercept form
y = mx + n

The function t therefore describes a line with slope 2 and y-intercept 4. Therefore the answer is A.
