Five times the sum of 9 and some number is 145. What is the number?

Andrews [41]

Answer:

x=20

Step-by-step explanation:

5(x+9) =145 (watch carefully)

5x + 45 = 145

5x + 45 - 45 = 145 - 45

5x = 100

5x/5 (to cancel eachother out) then --> 100/5

x=20

: Write the equation of the line in Point-Slope Form given the information below. Slope=-2 Point=(1,-1)

natulia [17]

Answer: y+1=-2(x-1)

Step-by-step explanation:

The point-slope formula is $y-y_{1}=m(x-x_{1})$ . Since we know the coordinate and slope, we can directly plug them in.

$y-(-1)=-2(x-1)$

$y+1=-2(x-1)$
