Write the phrase as an expression. Then simplify the expression. 7 plus sum of a number x and 5
jeka57 [31]
7+(x+5) would be the answer because sum means addition and it says x and 5. then it says 7 plus that so you put 7. In reality you wouldn't need parenthesis, but if you want it to match the phrase, you can put it in parenthesis.

Please help me!!!!!!!!!

Answer:

Step-by-step explanation:

Using the equation of line

y - y_1 = m(x - x_1)

y = mx + C

First first the slope of the equation

y = 9x - 4

Note: if two lines are perpendicular, their slope will be negative reciprocal

Slope = 9, but because it is perpendicular

m = -1/9

Using the equation

y - y_1 = m(x - x_1)

With the point (-9,-17)

x_1 = -9

y_1 = -17

y - (-17) = -1/9(x - (-9)

y + 17 = -1/9(x + 9)

y = -1/9(x + 9) - 17

Open the bracket.

y = (-x -9)/9 - 17

Lcm is 9

y = -x -9 - 153 / 9

y = -x - 162 / 9

Let's separate

y = -x/9 - 162/9

y = -x/9 - 18

y = -1/9x - 18

Therefore, the equation of the line is y = -1/9x - 18
