Answer:
x = - 4
Step-by-step explanation:
x = 19 is a vertical line parallel to the y- axis
A line parallel to it has the equation
x = c
where c is the value of the x- coordinates the line passes through
The line passes through (- 4, 7 ) with x- coordinate - 4 , then
x = - 4 ← equation of parallel line
In this image, the two angles (equations) form a right angle, which is 90°. You combine these equations: 4y-7+3y-1. When you combine like terms, you get 7y-8. You set this equal to 90°. 7y-8=90. Solve for y, and you get y=12.
Since he started with Nothing
He had zero initially
After x Months...
He'll have 10x naxvips
in slope intercept form
y=10x
To get the y values ... substitute the corresponding x value
For x=0
y=10(0)
y=0. Which is true cos he had no naxvip initially
x=1
y=10(1)
=10. Which is true cos he buys 10 more monthly... So 10 + 0 = 10.
x=2
y=10(2) = 20. This is true cos he added an additional 10 after each month
x=7
y=70.
Answer:
x = 21
Step-by-step explanation:
3x + 18 + 4x + 15 = 180
7x + 33 = 180
7x = 147
x = 21
Answer:
3 1/3 or 3.3(repeated)
Step-by-step explanation:
2/3 ÷ 1/5
= 2/3 × 5
= 10/3
= 3 1/3 or 3.3(repeated)
I hope this helped!
