Y = 3x - 4
y = 3(-1) - 4
y = -3 - 4 = -7
Graph pair is (-1, -7)
y = 3(0) - 4
y = 0 - 4 = -4
Graph pair is (0, -4)
y = 3(2) - 4
y = 6 - 4 = 2
Graph pair is (2, 2)
y = 3(4) - 4
y = 12 - 4 = 8
Graph pair is (4, 8)
Answer:
170cm²
Step-by-step explanation:
so the middle rectangle part first
15x10=150
then there's triangles so i'm gonna skip the divided by 2 part.
5x4=20
150+20=170
138% is the combined answer of this equation

Answer:</h3>
<h3>
Step-by-step explanation:</h3>
In this question, we're trying to find the probability of a male that also studies Spanish.
In this case, we know that:
- There's a 40% chance of a student being a male
- Probability of a male that studies Spanish is 25%
With the information above, we can find the probability.
To find the probability, we would need to find how much of 40 is 25%.
To do this, we would multiply 0.4 (40%) by 0.25 (25%) to find our probability.
Solve:
The probability of a male that studies Spanish is 10%
Your answer would be A). 10%

Answer:
- equation: 1368 = 380 +52x
- labor hours: 19
Step-by-step explanation:
The desired equation will relate labor cost, parts cost, and total cost.
<h3>A.</h3>
The total cost is the sum of the parts cost and the product of labor hours and labor rate. We're told to use x to represent labor hours.
total cost = part cost + (labor rate)(labor hours)
1368 = 380 + 52x
__
<h3>B.</h3>
This equation can be solved in 2 steps:
988 = 52x . . . . . . . step 1, subtract 380 from both sides
19 = x . . . . . . . . . . step 2, divide both sides by the coefficient of x
The number of labor hours was 19.
