The answer is C because 90-55 is 35 and 90+55+35=180
Answer:
Height = 20 ; Base = 5
Step-by-step explanation:
Triangle Area = Base x Height x 1/2
50 = 1x × 4x × 1/2
50 = 4x^2 × 1/2
50 = 2x^2
25 = x^2
x=5
Height equals to 4x -> 4 × 5 = 20
Base equals to x -> 1 × 5 = 5
Answer:
Figure out the x and y intercepts.
Step-by-step explanation:
you should find what the y or x intercept's are.
To figure that out you need to divide the number next to x or y to 8. use x to find out x intercept and y for y intercept.
lets find out y intercept
8 / -2 = -4
and now x intercept
8 / 3 = 1.75 or 1 (3/4)
Once you found out the intercepts you can now graph the equation.
Answer:
y=3/5x-1
Step-by-step explanation:
The formula you need to find this would be
(y-y1)=m(x-x1)
The y1 is your y point.
The x1 is your x point.
m is your slope.
Start by plugging in your numbers that they provide you.
(y-8)=3/5(x-15)
Now you need to distribute the slope to the terms inside the parenthesis next to it.
3/5(x)=3/5x
3/5(-15)= -9 Now you put those back into the equation.
(y-8)=3/5x-9
At this point you can get rid of the parenthesis around the y-8 since it is basically saying to take the term times 1.
To get y alone we not need to add 8 to both sides.
y-8=3/5x-9
+8 +8
y=3/5x-1
