Answer:

(1,10)

Step-by-step explanation:

Substitute the value of y so you get -5x+15=-2x+12.  Then solve you get x=1. Substitute x as 1 in the equation y=-2x+12 so you get y=10

Which is the solution to the inequality? y minus 27 greater-than-or-equal-to negative 13 y greater-than-or-equal to negative 40
djyliett [7]

Answer:

y\geq 14

y greater than or equal to 14

Step-by-step explanation:

Given the inequality:

y-27\geq -13

We solve it by isolating the variable y on one side. That is, in our case we add 27 to both sides and get:

y-27\geq -13\\y\geq 27-13\\y\geq 14

Write an equation of a line in slope intercept form that is parallel to y = 3x+6 and passes through the point (-10, 2.5)
TiliK225 [7]

1) Line should be parallel to y = 3x+6, so slope of this line should be =3.

y=mx +b

y=3x +b

Now we have to find b (y-intercept), using the point (-10, 2.5).

2.5 = 3*(-10)+b

b=2.5+30=32.5

y=3x + 32.5

2) The line should be perpendicular to y = -4x -2, so its slope is going to be negative reciprocal m= 1/4.

Now we have to find b (y-intercept), using the point (-16, -11).

y=(1/4)x +b

-11=(1/4)*(-16) + b

-11 = -4 +b

b = -7

y=(1/4)x - 7
