Answer:
x = 50
Step-by-step explanation:
The marked angles are vertical angles, so are congruent.
3x -3 = 147 . . . . congruent angles have equal measures
x -1 = 49 . . . . . divide by3
x = 50 . . . . . . add 1
Jus plot the points in then draw a line through them.
I will attach a graph example of it
The slope is the rate of change
You can find it in two ways
1: visually, draw a triangle and count from vertically to horizontally
2: slope formula - I will show it this way
(Y2-y1)/(x2-x1)
Given points (3,12), (4,16)
(16-12)/(4-3) = 4/1 = 4
The slope is 4
The slope represents the $ per hour. In this case, the wage is $4 per hour.
Inversely proportional:
y = constant/x, or y*x = constant. Let's see which give the *same* product:
a) 6*1.5 = 5*1.25 NO
b) 5*2 = 4*3 NO
c) 4*2.25=6*1.5 YES!!!
d) 4.5*3 = 6*4 NO
So, C)!!!
Answer:
56 yds
Step-by-step explanation:
Simply add up all the sides to find your perimeter:
12 + 12 + 18 + 14 = 56
Make the two equations equal together and solve for x
(x/3) = -2x+7
multiple both sides by 3
x=-6x+21
solve for x
7x=21
x=3.
now plug in 3 into one of the equation to find your y value.
y=-2(3)+7
y=1
write your answer as a coordinate; (3,1)
