Which graph represents this system 2x-5y=-5 y=2/5x+1

option D

The last option

Step-by-step explanation:

Which graph represents this system 2x-5y=-5

y=2x/5+1

Comparing the equation with the slope intercept equation, y= mx + c,

The slope,m = 2/5

From the graph, slope = (change in value of y)/ (change in value of x)

= (y2 - y1) / (x2-x1)

y2 = 1

y1 = 0

x2 = 0

x1 = 2.5

Slope, m =( 1-0)/(0 - - 2.5) = 1/(0+2.5)

= 1/2.5

Multiply numerator and denominator by 2

m= (1×2)/(2.5×2)

= 2/5

This corresponds to the slope of the equation given at the beginning.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
