=5 + 3 + 3 * 15
do multiplication first
=5 + 3 + 45
=8 + 45
=53
ANSWER: 53
Hope this helps! :)
The equation in slope-intercept form to represent the relationship between hours worked (x) and earnings in dollars (y) is y = $5 + $15x.
An equation in slope intercept form is usually written as: y = mx + b
Where:
If I earn $15 per hour when I babysit, the amount I earn increases by $15 every hour. $15 is the slope of the equation. After 3 hours, the total amount I would earn is: $15 x 5 = $45.
In order to determine the intercept, subtract $45 from $50.
$50 - $45 = $5.

Answer: Number one would be 3x+2y+-14 and x+y=-4, second one is x=-3, y=7
Step-by-step explanation:
The first one is solved by inputting the x and y in each one and finding which one comes out true, the second on is solved by substitution. to find x you would subtract x in the first equation and make it y=4-x then input that equation in the y in the second equation.
Answer:
The area of the shape can be divided into the area of the rectangle, and the area of the semi-circle.
The area of the rectangle can be found by
The area of a semi-circle can be found with the formula where r is the radius.
Since we know the diameter of the semi-circle is 4,
the radius will be 4 ÷ 2 = 2.
Therefore, the area of the semi-circle is
Therefore, the area of the shape is or (3 decimal places)
Answer:
-5
Step-by-step explanation:
or, f(x) = -x^2+10x+16
or, f(7) = (-7)^2+10*-7+16 (-7*-7=49)
=49-70+16
=65-70
=-5
