Bill plans to buy school supplies and the following equation represents what he bought.
5x + 20y = 50 is the equation that shows that he spent $50 and bought 5 binders and 20 pencils. Let
X represent the cost of binders and y represent the cost of pencils
1. How much is each binder if each pencil cost $0.50? Explain how you know.
2. How much is each pencil if the binders cost 8 dollars each? Explain how you know.
Answer:
1. x = 8
2. y = 1/2
Step-by-step explanation:
1. Plug the function
5x + 20(0.50) = 50
= 5x + 10 = 50
Subtract 10 from both side
= 5x = 40
Divide 5 on both sides
= x = 8
2. Plug in the function
5(8) + 20y = 50
= 40 + 20y = 50
Subtract 40 on both sides
= 20y = 10
Divide 20 both sides
= y = 10/20 | 1/2
Answer:
1. 8
Explanation: 5x + 20(.50)=50
5x + 10=50. Now do 50-10 to get 40. So,
5x=40. Now divide 40/5 to get 8.
2. .5
5(8) + 20x=50. Now do 5*8
40 + 20x=50. Now, 50-40 to get
20x=10. And divide 10/20 to get .5

A contractor brought 10.8 ft^2 of sheet metal. She has used 3.7 ft^2 so far and has $127.80 worth of sheet metal remaining. The equation 10.8x-3.7x=127.8 represents how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square foot?
Answer:
[tex]\$18[/tex]
Step-by-step explanation:
Let the cost of sheet metal per square feet be [tex]x[/tex]
Amount of sheet metal bought is [tex]10.8\ \text{ft}^2[/tex]
Amount of sheet metal used is [tex]3.7\ \text{ft}^2[/tex]
Remaining value of the sheet metal is [tex]\$127.8[/tex]
So we get the equation
[tex]10.8x-3.7x=127.8\\\Rightarrow 7.1x=127.8\\\Rightarrow x=\dfrac{127.8}{7.1}\\\Rightarrow x=18[/tex]
So, cost of sheet metal per square feet is [tex]\$18[/tex].

Use proportional reasoning to find 45% of 200
Answer:
90 i think :)
Step-by-step explanation:
Answer:
90
Step-by-step explanation:
By reasoning, we can say 50% of 200 is 100
We can say 10% of 200 is 20
We divide 20 by 2 to get 5%
20/2
= 10
Subtract 100 by 10
100 - 10
= 90
45% of 200 is 90

THISS IS SURGENT PLSSS Form a polynomial whose zeros and degree are given.
Zeros: -7, multiplicity 1 3;multiplicity 2; degree 3
Type a polynomial with integer coefficients and a leading coefficient of 1 in the box below.
Answer:
The polynomial is x^3-x^2-33x+63
Step-by-step explanation:
Here, we want to find a polynomial of degree 3 with the given roots
-7 with a multiplicity of 1 and 3 with a multiplicity of 2
if x = -7
x + 7 is a root
if x = 3
x -3 is a root
Since the multiplicity of this is 2, we have x-3 twice
The complete polynomial is;
(x-3)(x-3)(x+7)
= x^2-6x+9(x + 7)
= x(x^2-6x+9) + 7(x^2-6x+9)
= x^3-6x^2 + 9x+7x^2-42x+63
= x^3-x^2-33x+63

the fifth term of an arithmetic progression is 40 and the seventh term is 28 more than the 3rd term. Find the first and 10th term.
Answer:
Step-by-step explanation:
t5 = a + (5-1)d
t5 = a + 4d
40 = a + 4d
t3 = a + 2*d
t7 = a + 2d + 28 = a + 6d
Start with the seventh term which has 2 equal answers
a + 2d + 28 = a + 6d Subtract a from both sides
2d + 28 = 6d Subtract 2d from both sides
28 = 4d Divide by 4
28/4 = d
d = 7
==================
t5 = a + 4d = 40
a + 4*7 = 40
a = 40 - 28
a = 12
===================
First term is 12
10th term is
t10 = 12 + (10 - 1)*7
t10 = 12 + 9*7
t10 = 75

find the highest commen factor of 30 and 18
Answer:
6
Step-by-step explanation:
Use prime factorization;
30 = 2 * 3* 5
18 = 2 * 3 * 3
Both of these numbers have ( 2 * 3 ) in common, ( 2 * 3 = 6 ), hence their highest common factor (greatest common factor) is 6.
Answer: the common factor is 6
Step-by-step explanation:
the factor of 30=1x2x3x5
the factor of 18=1x2x3x3

Find the equation of the line that passes through the points (4,1) and (-4, -5)
A. y = 4x + 1
B. y = -4x - 5
C. y = 3/4 x -2
D. y = -3/4 x + 2
First, we must find the slope of the line using slope formula*.
[tex]m = \frac{-5 - 1}{-4 - 4} = \frac{-6}{-8} = \frac{3}{4}[/tex]
Second, we now find the y-intercept, or b, using slope-intercept form, the slope we found, and one of the given points.
[tex]1 = \frac{3}{4}(4) + b\\\\1 = 3 + b\\\\-2 = b[/tex]
Lastly, we can now create the equation of the line.
[tex]m = \frac{3}{4}\\[/tex][tex]b = -2[/tex]The equation of the line that goes through the given points is C. [tex]y = \frac{3}{4}x - 2[/tex]
(Please this is URGENT!) On a computer screen, Jennifer just created a triangular design of a banner with vertices at A(-4,3), B(-1,5) and C(-1,2). She can use the computer software to perform transformations on this design.
Which sequence of two transformations could she perform so that the transformed vertices become A'(4,-5), B'(7,-7), and C'(7,-4)?
a. translating 6 units down, followed by translating 8 units to the right
b. reflecting about the line y = -2, followed by translating 8 units to the right
c. reflecting about the line y = -1, followed by reflecting about the y-axis
d. reflecting about the line y = -1, followed by translating 8 units to the right
Answer:
The correct option is;
d. Reflecting about the line y = -1, followed by translating 8 units to the right
Step-by-step explanation:
The coordinates of the vertices of the banner Jane created = A(-4, 3), B(-1, 5) and C(-1, 2)
By reflecting across the line y = -1, we get
A(-4, 3) by reflection across the line y = -1 gives A(-4, -5)
B(-1, 5) by reflection across the line y = -1 gives B(-1, -7)
C(-1, 2) by reflection across the line y = -1 gives C(-1, -4)
By translating 8 units to the right get
A(-4, 3) by translation 8 units right gives A prime (4, -5)
B(-1, 5) by translation 8 units right gives B prime (7, -7)
C(-1, 2) by translation 8 units right gives C prime (7, -4)
Therefore, the two transformation that she could perform so that the transformed vertices become A prime (4, -5), B prime (7, -7), and C prime (7, -4) are;
1) Reflection across the line y = -1
2) An horizontal translation 8 units to the right get.
Transformation involves changing the size and position of a shape.
The sequence of two transformations are: (d). reflecting about the line y = -1, followed by translating 8 units to the right
The coordinates of ABC are given as:
[tex]\mathbf{A =(-4,3)}[/tex]
[tex]\mathbf{B =(-1,5)}[/tex]
[tex]\mathbf{C =(-1,2)}[/tex]
First, the coordinates of ABC are reflected across the line [tex]\mathbf{y =-1}[/tex]
The transformation rule is:
[tex]\mathbf{(x,y) \to (x,-y -2 \times 1)}[/tex]
So, we have:
[tex]\mathbf{A' = (-4,-3 -2 \times 1)}[/tex]
[tex]\mathbf{A' = (-4,-5)}[/tex]
[tex]\mathbf{B' =(-1,-5 - 2 \times 1)}[/tex]
[tex]\mathbf{B' =(-1,-7)}[/tex]
[tex]\mathbf{C' =(-1,-2 -2 \times 1)}[/tex]
[tex]\mathbf{C' =(-1,-4)}[/tex]
Next, the shape is translated 8 units right.
The rule of this transformation is:
[tex]\mathbf{(x,y) \to (x + 8, y)}[/tex]
So, we have:
[tex]\mathbf{A" = (-4 + 8, -5)}[/tex]
[tex]\mathbf{A" = (4, -5)}[/tex]
[tex]\mathbf{B" =(-1+8,-7)}[/tex]
[tex]\mathbf{B" =(7,-7)}[/tex]
[tex]\mathbf{C" =(-1+8,-4)}[/tex]
[tex]\mathbf{C" =(7,-4)}[/tex]
Hence, the sequence of two transformations are:
(d). reflecting about the line y = -1, followed by translating 8 units to the right
