Answer:
$440
Step-by-step explanation:
You need to find the unit rate by dividing how much he earned (88)by how many hours he worked (8) which equals $11 per hour.Then you take the unit rate (11) and multiply it by 40 which equals $440.
Answer:
47
Step-by-step explanation:
When an expression is evaluated, the expression is either simplified or calculated.
The result of the expression is 47
The expression is given as:
Where:
x = 2 and y = 4
Substitute 2 for x and 4 for y in the expression
So, we have:
Evaluate all exponents
Evaluate all products
Evaluate like terms
Hence, the result of the expression is 47
Answer:
6
Step-by-step explanation:
10-7=3
2*3=6
Answer:
y= -1.5x-7 is the equation of the perpendicular line
Here's why:
when we convert 2x-3y=8 to standard form, we get y= 2/3x-8/3. This means the perpendicular line will have a slope of the negative reciprocal of the original one, so the perpendicular slope is -1.5. When we substitute the points (-2,-4) into the equation y=-1.5x+b, we get a b value of -7. So the perpendicular line equation is y= -1.5x-7. You can't the parallel line equation with the points (-2,-4) as it is part of the line 2x-3y=8.
