Answer:
A. Subtraction Property of Equality
Step-by-step explanation:
3x + 4 = 10
Subtract 4 from both sides ---->Subtraction Property of Equality
3x + 4 - 4 = 10 - 4
3x = 6
So
If 3x + 4 = 10, then 3x = 6
Answer
A. Subtraction Property of Equality
D the slopes are negative reciprocals
Answer: $271.15
Step-by-step explanation:
$5.80 × 40 = 232
Time and a half = $8.70
Overtime is 4.5 hours
$8.70 × 4.5 = 39.15
$232 + 39.15 = 271.15
Hi
f(x) = g(x) if -x²+3x-2 - ( -x+1) = 0
-x² +3x-2 +x-1 = 0
-x² +4x -3 = 0
To solve, tou have to use the general method of resolution of a quadratic fonction.
To determine if it's has a solution in R, let's calculate Δ
Δ = (4)² - 4 * (1) *(-3)
Δ = 16 +12
Δ= 28
as Δ≥ 0 so the function allow two solution within R
so S 1 = ( -4 +√28) / 2 S 2 = (-4 -√28 ) /2
S1 = ( -4 + 2√7) /2 S2 = (-4 - 2√7) /2
S1 = (2 (-2 +√7) /2 S2 2 (-2 -√7) /2
S1 = -2 +√7 S2 = -2 -√7
So the two function are equal twice. one for x = -2 +√7 and second x = -2-√7
(3,0) and (0,-9)
Explanation: type the equation in a graphing calculator and the answer is the points where the line crosses the x and y axis
