Rewrite the equation in slope-intercept form. 8x-4y=20

xz_007 [3.2K]

Slope intercept: y = mx + b
Subtract 8x
-4y = 20 - 8x
Divide by -4
Y = -5 + 2x
Switch around
Solution: y = 2x - 5

X+4Y=-8 find the x intercept: find the y intercept: graph the line.

galben [10]

Answer:

x-intercept = (-8, 0)

y-intercept = (0, -2)

Step-by-step explanation:

Given linear equation is: x + 4y = - 8

For x - intercept: Plug y = 0 in the above equation.

$\implies x +4(0) = -8\\\\\implies x +0 =-8\\\\ \implies x = -8\\\\ \boxed{\red{\bold{\implies x- intercept = (-8,\:0)}}}$

For y - intercept: Plug x = 0 in the given linear equation.

$\implies 0 +4y = -8\\\\\implies 4y=-8\\\\ \implies y = \frac{-8}{4}\\\\ \implies y = -2\\\\ \boxed{\purple{\bold{\implies y- intercept = (0,\:-2)}}}$

What value of × is in the solution set of -5×-15>10+20×

vazorg [7]

Answer: $x$

Step-by-step explanation:

$-5x-15>10+20x$

Subtract 20x

$-5x-20x-15>10$

add 15

$-5x-20x>10+15$

Combine like terms

$-25x>25\\$

Divide by -25 (NOTE: When dividing or multiplying by negative numbers the inequality sign flips.)

$x$

Help me out pleaseeee

gladu [14]

4x - y = 5 --> 4x = y + 5

substitute

4x + 4y = -4

(y + 5) + 4y = -4

5y + 5 = -4

5y = -9

y = -1.8

solve x

4x = y + 5 = -1.8 + 5 = 3.2

x = 3.2/4 = 0.8
