The answer is -3

You use the formula y1-y2
———
x1-x2
-1 and 8 are your y’s
1 and -2 are your x’s

Your equation should look like this
-1-8 -9
—— = —— = -3
1-(-2) 3

I plugged the y’s and x’s into the formula.
I hope this helps!!

Please help me solve for angle B!!
Vaselesa [24]

I believe it is 50 degrees

Explanation:

180-115 = 65 degrees

Since the base angles of of an isosceles triangle are equal,

Angle C =angle A= 65 degrees

65 times 2 = 130

180-130=50

50 degrees=measure of angle B

Hope this helps

I NEED HELP ASAP plsssssssssssssssss​
Novay_Z [31]

Answer:

(-4,-2)

Step-by-step explanation:

first u should chose a variable to eliminate and i choose Y

y=5/2x+8-y=-1/4x-3

get a common denominator

5/2= 10/4

-1/4=-1/4

the equation i will change a little because we are subtracting

10/4x+8+1/4x+3

11/4x+11

solve for the remaining variable which is X

subtract 11 on both sides

0-11=11/4x+11-11

-11=11/4x

multiply both sides by 4/11

-11 times 4/11= 11/4x times 4/11

x=-4

then substitute the variable in one of the equations and i choose y=5/2x+8

5/2(-4)+8= y

-20/2+8= y

-10+8=y

y=-2
