Answer:
x = -3 or x = -5
Step-by-step explanation:
Solve for x:
(x + 3) (x + 5) = 0
Split into two equations:
x + 3 = 0 or x + 5 = 0
Subtract 3 from both sides:
x = -3 or x + 5 = 0
Subtract 5 from both sides:
Answer: x = -3 or x = -5
Answer:
A
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 )
y = - x - 6 ← is in slope- intercept form
with slope m = -
Given a line with slope m then the slope of a line perpendicular to it is
= - = - = 3
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
here m = 3 and (a, b) = (- 1, 5), thus
y - 5 = 3(x - (- 1)), that is
y - 5 = 3(x + 1) → A
Answer:
c = $30 + $0.75p
Step-by-step explanation:
total cost = total fixed cost + total variable cost
total fixed cost = $30
Fixed costs are costs that do not vary with output.
total variable cost = variable cost per unit x total unit
p x 0.75
Variable costs are costs that vary with production
Answer:
x = -2
Step-by-step explanation:
6 more then the product of 5 and a number x is -4
" the product " means multiply
5x + 6 = -4
5x = -4 - 6
5x = -10
x = -10/5
x = -2 <===
