Answer: 9" by 7"
Step-by-step explanation:
let the dimensions of the rectangle be x and y
equation 1: xy=63
equation 2: 2(x+y)=32
first, rearrange the terms
(1′): y=63/x
(2′): y=16−x
(1′)-(2′): 0=63/x−16+x
multiply the equation by x
0=x2−16x+63
0=(x−9)(x−7)
so x = 7 or x = 9
from this, y = 9 when x = 7 and y = 7 when x = 9
so, the dimension of the rectangle is 9″ by 7″

Your friend doesn't have to pay for a phone, but their parents charge them $3 an hour when they are on it. If you and your friend are both on your phone for the same amount of time (90 hours), who would be charged less money
Answer:
I don't understand who would be charged less money cause it's just the parents and the child and the child is only paying them from the hours being on the phone. but from what I know 90÷ 3 is 30. so the parents would be making like $30 but if its multiplication 90×3 is like 270

Describe the graph of the equation Y equals 6X
Answer:
Make a line using points (0,0) (1,6) and (-1,-6)
Step-by-step explanation:
Okay, so your first point will be (0,0) at the origin because in your equation there is no y-intercept.
For your next point, we have to use Rise/Run, or slope, to find our next point. In y=mx+b, m is the slope. So for y=6x, 6/1 is our slope.
So from the origin, we go up 6 and to the right once. This will give us the point (1,6)
Incase you need another point, we can also go down 6 and left 1. This gives us the point (-1,-6)
Hopefully this helps! Leave a comment if it does, and ask your teacher to see if it's right! <3

Do these pairs of values (x and y) represent two quantities that are proportional?
X: 4, 6, 10, 14
Y: 2, 3, 5, 7
A. No, because none of the pairs is a simplified ratio.
B. Yes, because all of the pairs represent the same ratio.
C. Yes, because as x increases, y increases.
D. because each y-value is less than the corresponding x-value.
B. Yes, because all of the pairs represent the same ratio
Answer:
yes it is B
Step-by-step explanation:
because all of the numbers divided equals 2

if you have 3 pounds of apples and they cost 12$ whats the unit price
Answer:
unit price = 4$ a pound
Step-by-step explanation:
3 pounds for a total of 12$, but you need to know the price of 1 individul unit, so within those 3 lbs is 3 "individul units" (aka 1 pound)
total cost = 12$ for all 3 units so divide 12 by 3 (12/3) = 4 --> Giving you the cost of 1 unit which is $4.00
Check you work : 3 units (3lbs) , you know 1 unit(pound) costs 4$ and your total you paid needs to be equal to 12$
SO: 3 (your pounds) x 4 (price PER unit) = 12
12 = 12

Answer:
The vertex is (-3,0)
Step-by-step explanation:
Insert the values into the given equation on the assignment in order to get the coordinates of the vertex.
The values are:
a = 1
b = 6
c = 9
For the x coordinate, insert the a and b values into the equation (-b/2a):
-6/(2*1) =
-6/(2) =
-3
So now we know the x value is 3, to find the y value insert the a, b, and c values into the equation -(b^2-4ac)/4a
-(6^2 - (4*1*9))/(4*1) =
-(36-(36))/4 =
-0/4 =
0
So the y value is 0 and the vertex is (x,y), so the vertex is (-3,0)

How do you think you could simplify f(x) + g(x) if f(x) = 3x + 2 and g(x) = 4x?
Step-by-step explanation:
f(x) = 3x + 2
g(x) = 4x
= f(x) + g(x)
= 3x + 2 + 4x
= (3 + 4)x + 2
= 7x + 2
(f+g)(x) = 7x + 2

Three times a number minus another number is -3. The sum of the numbers is 11. Find the numbers.
Answer:
they are 2 and 9
Step-by-step explanation:
Set up equation for two numbers a and b:
[tex]3a-b=-3[/tex] and [tex]a+b=11[/tex]
solve the system of equations:
add two equations together we get:
[tex]3a-b+a+b=-3+11[/tex]
[tex]4a=8[/tex]
[tex]a=2[/tex]
Since, a+b=11
thus [tex]b = 9[/tex]
Inclined Ramp A 2-pound weight is attached to a 3-pound
weight by a rope that passes over an ideal pulley. The smaller
weight hangs vertically, while the larger weight sits on a
frictionless inclined ramp with angle 0. The rope exerts a
tension force T on both weights along the direction of the
rope. Find the angle measure for that is needed to keep
the larger weight from sliding down the ramp. Round your
answer to the nearest tenth of a degree.

The angle measure for the inclined ramp needed to keep the larger weight from sliding down the ramp is 42⁰.
The given parameters;
mass of the small block, m = 2 lb = 0.91 kgmass of the larger block, = M = 3 lb = 1.36 kgThe normal force on the larger weight (3 lb) is calculate as;
[tex]F_n = Mgcos(\theta)[/tex]
The net force on the larger weight is calculated as;
[tex]Mgsin(\theta) - T = 0[/tex]
where;
T is the tension on the wire due to the smaller weight pulling up the 3 lb weight.T = mg
[tex]Mgsin(\theta) - mg = 0\\\\(1.36\times 9.8)sin\theta \ - \ (0.91 \times 9.8) = 0\\\\13.328 sin(\theta) = 8.918\\\\sin(\theta) = \frac{8.918}{13.328} \\\\sin(\theta) = 0.669\\\\\theta = sin^{-1} (0.669)\\\\\theta = 42\ ^0[/tex]
Thus, the angle measure for the inclined ramp needed to keep the larger weight from sliding down the ramp is 42⁰.
