Which system of equations is equivalent to the system of equations shown?

Ivanshal [37]

<span>I can solve for x and y
A) 2x - 4y = 12
A) 2x = 4y + 12
A) x = 2y + 6
Substituting into B
B) 3* (2y +6) - 5y = 20
B) 6y + 18 -5y = 20
B) y = 2
B) x = 10

Solve -4y - 3 + 3y = 8 - 2y -15, interpret the result

Elenna [48]

Answer:

y = -4

Step-by-step explanation:

-4y - 3 + 3y = 8 - 2y - 15

~Combine like terms

-y - 3 = -2y - 7

~Add 3 to both sides

-y = -2y - 4

~Add 2y to both sides

y = -4

Best of Luck!

Find the y intercept and slope

Naya [18.7K]

Okay so first off the equation of a line is
Y=mx+b
m= the slope
b= the y intercept

The Y intercept of this line is 2 and the slope is 5/3! You know this is the slope because if you start at point a and go up 5 and to the right 3, you end up at point b.

The equation for this line would be y=5/3x+2

Hey there,

Question #1

The answer would be in the attachment below.

Question #2

The answer would be in the attachment below.

Question #3

The answer would be in the attachment below.
_____________________________________________________________

Question 4#

The last one was kind of tricky. But, as I saw this attachment, I noticed on how the rectangle was actually 3/4 on the base and for the height, it was 1/2. So by doing this,we need to find the area, and we would multiply these both. 1/2 x 3/4 = 3/8 but by looking at your options, those are not simplified so . . .your answer would be 6/16 because 3x2=6 & 8x2=16.

I really hope this can help you Amanda.

Have a great day! =)

I’ll give brainly

tresset_1 [31]

Answer:

take 45 degree as reference angle

use sin rule

sin 45=opposite/hypotenuse

1/ $\sqrt{2}$ =b/10(do cross multiplication)

b $\sqrt{2}$ =10

b=10/ $\sqrt{2}$
