Set it equal to each other. 3x-38+7x-95=47. 10x-133=47. 10x=180. X=18
Answer:
y = - 2x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (8, - 9) and (x₂, y₂ ) = (- 4, 15)
m =
=
= - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, - 9), then
- 9 = - 16 + c ⇒ c = - 9 + 16 = 7
y = - 2x + 7 ← equation of line
Answer:
x=-2.8
Step-by-step explanation:
14 tens is equal to 140. You get this by multiplying 14 and 10. So the answer to your question is 140.
Answer:
5,000
Step-by-step explanation:
When a number is 5 or above, you would round up. When it is below 4 or below, you round down.
Since 5,182 the 1 is below 1, 5 would remain the same.
