Answer:
-14
Step-by-step explanation:
Think of it like this-
subtracting a negative is like adding a positive, so all you have to do is add a negative sign to the sum after solving these sort of problems :>
Hope this helps!
Answer:
C
Step-by-step explanation:
The table shows a linear function.
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 ) = (1, 3) and (x₂, y₂ ) = (2, 7) ← 2 ordered pairs from the table
m = 
= 4, thus
y = 4x + c ← is the partial equation
To find c substitute any ordered pair into the partial equation
Using (1, 3), then
3 = 4 + c ⇒ c = 3 - 4 = - 1
y = 4x - 1 → C
Answer:
y=145 and x=55
Step-by-step explanation:
Subtract 180 by 35 for y and 90-35 for x. Hope this helps again. Lol
Answer:
area= x^2+8x+7
Step-by-step explanation:
a=l*w
l=x+7
w=x+1
a=(x+7)(x+1)
a= x^2+8x+7
Answer: x = -6
Step-by-step explanation: The problem gave us the y value, so we can just substitute it into the equation and solve it.
y = x - 6
y = 2x
2x = x - 6 (substitute the y value into the equation)
1x = -6 (subtract x on each side)
x = -6 (1x is basically saying x so you do not need to divide)
