Solve by substitution 3y-2x=10 and x=9-2y

Mathematics

3y-2(9-2y)=10
3y-18+4y=10
-y-18=10
-y=28
y=-28
3(-28)-2x=10
-84-2x=10
-2x=94
x=-47
so x is -47 and y is -28

In triangle FGH, angle G is 30 degrees and angle H is 100 degrees. What is the measure of angle F? * 1 point 50 degrees 70 degre
serg [7]
Mark brainlist please!

Answer is 50 degrees

Since,

measure of angle F + measure of angle G + measure of angle H = 180

30 + 100 + measure of angle F = 180

Measure of angle F = 180 - 130

Measure of angle F = 50 degrees

Points (3,2) and (-5,6) are endpoints of the diameter of a circle.
vichka [17]

Answer:

A.8 B.(-1,4) C.(1,4)

Step-by-step explanation:

First, know that (3,2)=(x1,y1) and (-5,6)=(x2,y2)

A. The diameter is 8, given the diference between x1 and x2: 3-(-5)=8

B. The center point is given by (x1+x2)/2 and (y1+y2)/2

(x1+x2)/2 and (y1+y2)/2 = (3-5)/2 and (2+6)/2 = (-1,4)

C. The symmetric point of C about the x-axis is (1,4)

What is the x and y intercepts Of “ -2y=3x-6 “ ?
vesna_86 [32]

-2y=3x-6\ \ \ \ |:(-2)\\\\y=-1.5x+3

It's a slope-intercept form where a slope = -1.5 and y-intercept = 3.

x - intercept: y = 0

Therefore we have the equation:

-1.5x + 3 = 0    |-3

-1.5x = -3     |:(-1.5)

x = 2

Answer: x-intercept = 2, y-intercept = 3
