We are given 15-7 here and we have to express it as sum.

Let us first understand the property to be use here.

We can write (a-b) as (a+(-b))

For example:

If we have 7-2, we can rewrite it as 7+(-2)

and then we can combine them to get 5

Now let us use the above property for our question,

We are given,

15-7

rewriting it as addition,

15+(-7)

+ and - on multiplication will be (-)

so +(-7) will remain -7 only

Answer: 15-7 = 15+(-7)

Solve -4y - 3 + 3y = 8 - 2y -15, interpret the result
Elenna [48]

Answer:

y = -4

Step-by-step explanation:

-4y - 3 + 3y = 8 - 2y - 15

~Combine like terms

-y - 3 = -2y - 7

~Add 3 to both sides

-y = -2y - 4

~Add 2y to both sides

y = -4

Best of Luck!

Write an equation in point-slope form of the line that passes through the given point and with the given slope m.
il63 [147K]

y = mx + c

7 = 4(-8) + c

c = 39

The equation is y = 4x + 39

y - 7 = 4 ( x - (-8))

y -7 = 4 (x +8)
