Answer:

Solution → (3, -1)

Step-by-step explanation:

We ave to identify the graph representing the system of lines first.

y = $\frac{2}{3}x-3$

Y-intercept of the line = -3

y = -2x + 5

y-intercept of the line = 5

From the given graphs 3rd (extreme right) graph is representing the system of equations.

Solution of the system of equations will be the point of intersection of these lines.

Solution of the system → (3, -1)

What is the solution to -122 <-3 (-2-8×)-8×?

Furkat [3]

Answer:

solution is

$(-8,\infty)$

Step-by-step explanation:

we are given inequality as

$-122$

Firstly, we will simplify it

$-122$

now, we can subtract both sides by 6

$-122-6$

$-128$

now, we can divide both sides by 16

and we get

$\frac{-128}{16}$

$-8$

so, solution is

$(-8,\infty)$

30. Write an equation in point-slope form for the line through the given point with the given slope. (-7,9); m=4/5

tamaranim1 [39]

Equation in point-slope form is $y-9=4/5(x+7)$

Option C is correct.

Step-by-step explanation:

We need to Write an equation in point-slope form for the line through the given point with the given slope. (-7,9); m=4/5

The formula used for point-slope form is:

$y-y_1=m(x-x_1)$

We are given slope m = 4/5

Point (-7,9) where x₁ = -7 and y₁ = 9

Putting values in the formula:

$y-y_1=m(x-x_1)\\y-9=4/5(x-(-7))\\y-9=4/5(x+7)$

So, equation in point-slope form is $y-9=4/5(x+7)$

Option C is correct.

the area of a rectangular wall of a barn is 260 square feet. it's length is 6 feel longer than twice it's width. find the length

scoundrel [369]

L=2w+6
260=lw

Substitute for l
260=w(2w+6)
260= 2w^2+6w
2w^2+6w-260=0
2(w^2+3w-130)
2(w+13)(w-10)
w=-13, w=10

Since width cannot be negative it must be 10
260=l(10)
26=l

Final answer: length-26 ft, width-10ft
