1. A plumber charges $50 for a house call in addition to $80
per hour worked. Which equation represents y, the total cost
for x, hours worked?
Answer:
Step-by-step explanation:
Since the plumber charges $50 regardless of how many hours he works, then the equation must be 50 + ....
Since the plumber charges $80 for each hour, then the equation will be y = 50 + 80x.
Help please :( I am stuck
Answer: We all hate it when we are stuck! The slope is -1/2.
Step-by-step explanation: To find the slope, figure out the change of x divided by the change of y. The change of y is -1, and the change of x is 2. Therefore, the slope of the line is -1/2.

Solve this system of equations
y=7x+5
y=x+17
Answer:
(x, y) = (2, 19)
Step-by-step explanation:
7x + 5=x + 17
x=2
y=7*2+5
y=19
Please give brainlyist
Answer: (2, 19)
Step-by-step explanation:
There are three general ways to solve a system of equations:
- Substitution
- Elimination
- Augmented Matric
Since both given equations all have y isolated, substituting the value of y will be the most appropriate way here.
--------------------------------------------------------------------------------------------------------
Given
y=7x+5
y=x+17
Substitute y into the equations
7x+5=x+17
Subtract 17 on both sides
7x+5-17=x+17-17
7x-12=x
Subtract 7x on both sides
7x-12-7x=x-7x
-12=-6x
Divide -6 on both sides
-12/-6=-6x/-6
x=2
Substitute value into one of the equations
y=x+17
y=2+17
y=19
(2, 19)

How is the graph of y = - 4x2 – 5 different from the graph of y = -4x2?
A. It is shifted 5 unit(s) down.
C. It is shifted 5 unit(s) up.
B. It is shifted 5 unit(s) left.
D. It is shifted 5 unit(s) right.
Answer:
C. It is shifted 5 unit(s) up.
Step-by-step explanation:
The y-intercept of the first equation is –5. The y-intercept of the second equation is 0. This means that it moves up by 5 units.

3x - 5 = 7x + 11
Answer:
x=-4
Step-by-step explanation:
3x-5=7x+11 Add like terms
+5 +5
3x=7x+16 Do it again...
-7x -7x
-4x=16 Now divide
x=-4
Answer:
The answer is x=-4
Step-by-step explanation:
3x-5=7x+11
1) you have to move the number that has a variable with it onto one side(3x and +7x) and the numbers that do not have a variable move them onto the other side (-5 and +11),but if you move them you have to change the sign like the underlined numbers below
3x-7x=5+11
2) you have to subtract 3x and-7x which it equals -4x and then you have to add 5 and 11 which it equals 16
Equation now -4x=16
3) you have to divide -4x into -4x and also divide -4x into 16 which you will get x=-4

What is the sum of the interior angles of a regular polygon with 4 sides?
A. 180
B. 540
C. 1260
D. 360
Answer:
D. 360
Step-by-step explanation:
The sum of the interior angles of a regular polygon with 4 sides can be represented as: 180(n-2), where n is the number of sides in the polygon.
In this case, n=4, because there are 4 sides in this polygon.
180(4-2)
180(2)
360

si tienes una mesa de 25m de largo por 10 de ancho ¿ en cuanto varíaran cada una de sus dimensiones para que sin alterar su superficie tengo forma cuadrada
responder: 8,75
Cada dimensión será de 8,75 porque si la longitud es de 25 m de largo y el ancho es 10, si los sumamos y obtendremos 35. Así que 35 dividido entre 4 es 8,75

In a recent year, there were 15,900,000 high school
students in the United States. Suppose 250,000 of a
random sample of 500,000 high school students
during that year played on a sports team. Estimate
the total number of U.S. High school students that
played on a sports team that year.
Answer:
The total number of U.S. high school students that played on a sports team that year can be estimated to be 7,950,000.
Step-by-step explanation:
From the random sample, we can expect that [tex]\frac{250000}{500000}=\frac{1}{2}[/tex] of all students played on a sports team that year. So in the bigger sample of 15900000 high school students, we can expect [tex]15900000 \cdot \frac{1}{2} = 7950000[/tex] students to have played on a sports team that year.
