What is the graph of the system y = −2x + 3 and 2x + 4y = 8? Select one:

zhuklara [117]

y = -2x + 3....slope = -2, y int = 3

2x + 4y = 8
4y = -2x + 8
y = -1/2x + 2....slope is -1/2, y int is 2

this is graph C

Convert the rate 1000 ounces per 2 hours to cups per minutes?

Andrews [41]

125 cups in 120 minutes (because 1000 oz/8 = 125 cups and 2 hrs is 120 minutes)

$\frac{125}{120} = \frac{n}{1}$

now reduce the fraction by dividing the numerator and denominator by 5 = (optional)
$\frac{25}{24} = \frac{n}{1}$
So 24n = 25 Divide both sides by 24
n= 1 1/24 cups per minute

Use substitution to solve for x in the system of equations.

jolli1 [7]

Equation 1) 10x + 2y = 30
Equation 2) 4x + y = 4

Multiply all of equation 2 by 2.

2) 2(4x + y = 4)

2) 8x + 2y = 8
1) 10x + 2y = 30

Subtract equations from each other.

-2x = -22

Divide both sides by -2.

x = -22/-2

x = 11

B) x = 11

~Hope I helped!~
