Katarina [22]3 years ago

6 0

Answer:

Step-by-step explanation:

c does not have a slope so the slope is 0 and it is parallel to the x axis bc the line will be vertical on a graph making it perpendicular on the y axis

Compare the fractions using - 4/9 and -8/20

laiz [17]

Answer:

-2/45

Step-by-step explanation:

-4/9 is simplified and both 4 and 9 are perfect squares.

-8/20 can be reduced to -2/5 since both 8 and 20 are divisible by 4.

The difference between them is given by -4/9 - (-2/5) = (18-20)/45 = -2/45.

Y=1/4x+7 y=1/2x+5 The y-coordinate of the solution to the system shown is _____.

Brilliant_brown [7]

Answer:

The y-coordinate of the solution to the system shown is 9

Step-by-step explanation:

$y=\frac{1}{4}x+7\\y=\frac{1}{2}x+5$

We need to solve these system of equations and find value of y

Let eq (1) be $y=\frac{1}{4}x+7$

and eq(2) be $y=\frac{1}{2}x+5$

Putting value of y from eq(2) into eq(1)

$y=\frac{1}{2}x+5=\frac{1}{4}x+7\\\\\frac{1}{2}x-\frac{1}{4}x=7-5\\\frac{2x-x}{4}=2\\\frac{x}{4}=2\\x=2*4\\x=8$

Putting value of x=8 in equation 1 to find value of y

$y = \frac{1}{4}x+7$

$y = \frac{1}{4}(8)+7$

$y =2+7$

$y =9$

So, The y-coordinate of the solution to the system shown is 9
