Answer:
$573.75
Step-by-step explanation:
625.00x15%=93.75
625.00-93.75=531.25
531.25x8%=42.50
531.25+42.50=573.75
Answer: I think that the answer is $573.75
please correct me if im wrong.

Find the length and width of the frame
Answer:
The width is - 4 the lengeth is - 7
Step-by-step explanation:
w*l = 28in²
w = ?
l = w+3
w=2
2+3 = 5
5*2 = 10
w = 3
3+3 = 6
6*3 = 18
w = 4
4+3 = 7
7*4 = 28
So,
W = 4 L = 7
Each week jake gets an allowance of $8 plus $3 for each chore he does at
home. His younger sister bella gets an allowance of $6 plus $2 per each chore
she does. Write an expression for how much their parents give them each week if
they do the same number of chores.
Answer:
y = 5x + 14
Step-by-step explanation:
y represents the total money their parents give them. X represents the number of chores. 5 is the sum of 3 + 2 since Jack gets $3 for each chode while Bella gets $2 for each chore. 14 is the set amount of money the receive each week since 8 + 6 is 14.

Consider the following scenario describing the residents of Charlestown: The list pairs resident's ages with their zip codes.
Does this scenario represent a function?
No, because people who are the same age can have different zip codes
No, because people who have the same zip code can be different ages
Yes, because people who are the same age can have different zip codes
Yes, because people who have the same zip code can be different ages
Answer:
No, because people who are the same age can have different zip codes!!

Which table represents a nonlinear function?
Approximate the solution to this system of equations. y = –2x + 6 y = 4x – 1
Answer:
x = 1[tex]\frac{1}{6}[/tex], y = 3[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
y = -2x + 6 --- Equation 1
y = 4x - 1 --- Equation 2
Since both (-2x + 6) and (4x - 1) have the same total, y, they are equal.
-2x + 6 = 4x - 1
Isolate the like terms.
6 + 1 = 4x + 2x
Evaluate like terms.
6x = 7
Find x.
x = [tex]\frac{7}{6}[/tex]
x = 1[tex]\frac{1}{6}[/tex]
Substitute x = [tex]\frac{7}{6}[/tex] into Equation 2:
y = 4x - 1
y = 4([tex]\frac{7}{6}[/tex]) - 1
= 4[tex]\frac{2}{3}[/tex] - 1
y = 3[tex]\frac{2}{3}[/tex]
What is the correct value of x?
Answer:
x= -5
Step-by-step explanation:
First get X alone by dividing both sides by -4.2
-4.2x=21
-4.2. -4.2
then you're left with X = -5
To verify your answers, multiply -5 by -4.2
Please help me due tomorrow morning
Answer: Y=-5
Step-by-step explanation:
The reason is because if you look down the y axis from the origin you can see the location where the line crosses over the y axis in this case it was at (0,-5)
f(x) = 4/5x - 2
Find f(3)
[?
Answer:
f(3) = 2/5
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
Function NotationStep-by-step explanation:
Step 1: Define
f(x) = 4/5x - 2
f(3) is x = 3
Step 2: Evaluate
Substitute: f(3) = 4/5(3) - 2Multiply: f(3) = 12/5 - 2Subtract: f(3) = 2/5Answer: 2/5
Step-by-step explanation:
We need to replace x with 3
f(x)= 4/5*(3)-2= (12/5)-2=(12-10)/5= 2/5
4. A hot air balloon hovers 100 feet about the ground. The balloon is tethered to the ground with a
rope that is 250 feet long. At what angle of elevation, is the rope attached to the ground? Round
you answer to the nearest degree.
Answer:
[tex]\theta=24^\circ[/tex]
Step-by-step explanation:
Trigonometry and Right Triangles:
The ratios of the sides of a right triangle are called trigonometric ratios. Any angle or side length can be calculated using the appropriate trigonometric ratio.
Please refer to the image below. The balloon is 100 feet high and the rope has a length of 250 feet. The right triangle formed allows us to apply a trigonometric ratio that relates the two given side lengths: the hypotenuse and the opposite leg to angle θ.
The sine ratio is defined as:
[tex]\displaystyle \sin\theta=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]
[tex]\displaystyle \sin\theta=\frac{100}{250}=0.4[/tex]
[tex]\displaystyle \sin\theta=0.4[/tex]
Calculating θ:
[tex]\theta=\arcsin 0.4[/tex]
[tex]\theta=23.6^\circ[/tex]
To the nearest degree:
[tex]\mathbf{\theta=24^\circ}[/tex]

The relationship between a rubber band's length and the weight attached to it is a function. The more weight, the longer the rubber band will be. The increase of
the rubber band's length is called deflection Students in science class have measured how much a rubber band would stretch if different weights, in ounces,
were attached to it. They recorded the data collected in the experiment by constructing a graph:

Solve the system of equations - x - y = 6 and 5x -7y=66 by combining the equations
Answer: Let's solve for x.
−x−y=6
Step 1: Add y to both sides.
−x−y+y=6+y
−x=y+6
Step 2: Divide both sides by -1.
−x
−1
=
y+6
−1
x=−y−6
Answer:
x=−y−6
Let's solve for x.
5x−7y=66
Step 1: Add 7y to both sides.
5x−7y+7y=66+7y
5x=7y+66
Step 2: Divide both sides by 5.

9514 1404 393
Answer:
no
Step-by-step explanation:
When the second equation is put in standard form like the first equation is, then you can see they are different. They do not define the same line.
3x +2y = 7
x + y = 7 . . . . . second equation in standard form

i need help me wit this
Answer:
C: (1, 2.5)
Step-by-step explanation:
The point is not exactly on 2 or 3 on the y axis. So it is at 2.5. and when you read a graph you need to look at it from x to y so it should be C: (1, 2.5).
Solve for x: one over four (4x + 15) = 24
Answer:
x = 81/4
Step-by-step explanation:
multiply both sides by 4
4x + 15 = 96
subtract 15 from both sides
4x = 81
divide both sides by 4
x= 81/4
i hope that's right
Answer:
81/4

What is the slope of the line?
Answer:
-3/2
Step-by-step explanation:
Rise/run
You count down/up however many until the line hits another point, and then go across until it matches. So I counted down 3 squares and over 2, and since it is going down it is negative.
