Answer:
y = 5x + 2
5 is the slope 2 is the y-intercept
3x = -y + 10 turns into y = -3x + 10
-3 is the slope 10 is the y-intercept
they intersect at (1, 7)
step-by-step explanation:
I’m not sure what you are wanting me to do with these but i will give you all the information about them
y = 5x + 2 is already in slope-intercept form
5 being the slope and 2 being the y-intercept
to solve for 3x = -y + 10
-3x+y +y-3x
y = -3x + 10
the slope is -3
the y-intercept is 10
they intersect at (1, 7)
5 hours and twenty minutes
Answer:
19 m
Step-by-step explanation:
base=x
leg=3x-2
3x-2+3x-2+x=45
7x-4=45
7x=49
x=7
leg=3x+2=3(7)-2=19
Answer:
65 = <JKL
Step-by-step explanation:
There are two expressions that represent the same thing.
The diagram shows that <JKL = 45 + x
The question states that JKL = 3x + 5
The two expressions must be equal since they represent the same thing.
3x + 5 = x + 45
Subtract 5 from both sides
3x + 5 - 5 = x + 45 - 5
3x = x + 40 Subtract x from both sides
3x - x = x - x + 40
2x = 40 Divide by 2
2x/2 = 40/2
x = 20
So x + 45 = 20 + 45 = 65
or
3x + 5 = 3*20 + 5 = 60 + 5 = 65
