Step-by-step explanation:
We have y = 9x - 70 and y = 2x - 32.
=> 9x - 70 = 2x - 32
=> 7x = 38
=> x = 38/7 which is around 5.43.
Answer:
Equations are :--- y = 9x – 70 and y = 2x – 32
Substituting the value of y, we get
[tex]9x - 70 = 2x - 32 \\ 7x = 38 \\ x = \frac{38}{7} \\ \boxed{x = 5.43} \\ y = 9x - 70 \\ y = 9( \frac{38}{7} ) - 70 \\ \boxed{ y = - 21.14}[/tex]
Roger wants to have 400 copies of his resume printed. The first print shop Roger calls charges $21.50 for the first 200 copies and $10 for every 100 additional copies. The second print shop charges $0.15 per copy and has no deals on bulk
1.How much will it cost Roger at the first print shop?
2. How much will it cost Roger at the second print shop?
3. Which option is a better deal? How much will Roger save?
Please help!!!!:/
Answer:
3. I would say shop one because it's at a lower price. Although, it is up to you.
Step-by-step explanation:
Roger wants 400 copies; First print shop; $21.50 for first 200 copies + $10 for every 100 additional copies. Second print shop; $0.15 per copy + no deals on bulk
1. how much will cost roger at the first print shop?
$21.50 + $20 = $41.50 for 400 copies
2. how much will it cost roger at the second print shop?
$0.15 x 400 = $60

think about the process the relationship between x and y is represented by the equation y=19x how can you decide if the equation represents a porportianl relatingjip
Answer:
Since the value is always multiplied by the same factor(19), the relationship is proportional.
Step-by-step explanation:
To see if the equation represents a proportional relationship, we see if the division of y by x is always the same
[tex]x = 1, y = 19*1 = 19[/tex]
[tex]x = 2, y = 19*2 = 38[/tex]
[tex]x = 3, y = 19*3 = 57[/tex]
So
[tex]\frac{57}{3} = \frac{38}{2} = \frac{19}{1} = 19[/tex]
Equal, so proportional

Find the GCF of the pair of monomials.
32a,48a
Answer:
The greatest common factor (GCF) of these two monomials is [tex]16\, a[/tex].
Step-by-step explanation:
Rewrite [tex]32\, a[/tex] and [tex]48\, a[/tex] as the products of the variable [tex]a[/tex] and and prime number factors:
[tex]32\, a = 2 \times 2 \times 2 \times 2 \times 2 \times a = 2^{5}\times a[/tex] (where [tex]2[/tex] is a prime factor.)[tex]48\, a = 2 \times 2\times 2 \times 2 \times 3\times a = 2^{4}\times 3\times a[/tex] (where [tex]2[/tex] and [tex]3[/tex] are both prime factors.)Write an expression for the GCF of these two monomials in terms of these factors ([tex]2[/tex]'s, [tex]3[/tex], and [tex]a[/tex].) Try to include as many of each factor as possible, as long as the resulting product is present in both monomials.
For example, there are five factor [tex]2[/tex]'s in the first monomial but only four in the second monomial. Therefore, include the factor [tex]2\![/tex] in the GCF for only four times.
The factor [tex]a[/tex] appeared once in both monomials. Hence, include [tex]a\![/tex] for one in the expression for the GCF.
On the other hand, the factor [tex]3[/tex] is found in the second monomial but not in the first. Therefore, this factor should not be included in the expression for the GCF.
Therefore, the expression for the GCF would be:
[tex]2 \times 2\times 2\times 2 \times a = 16\, a[/tex].

Myra combined the like terms in the algebraic expression correctly.
Which statement correctly describes what Myra did?
8x^2 + 7-2x^2 + x
•Myra combined 8 and -2 to equal 6x2 +x+7- O
•Myra combined 8 and 2 to equal 10x2 +%+7
•Myra combined 8 and 7 to equal 15x2 - 2x + X-
•Myra combined 8 and 1 to equal gx2 - 2x2 +7-
(edge2020).
The answer would be the first one, combining 8 and -2
This is because the 2 like terms are 8x^2 and -2x^2. You can get this by looking in the problem. There are 2 terms with x^2 which means we have to combine them. One of them is 8x^2 (the 1st one) and the other is -2x^2 (since it says 7-2x^2)
If you combine these you will get 6x^2 [8+(-2)=6]
Answer:
Myra combined the like terms in the algebraic expression correctly. Which statement correctly describes what Myra did?
8 x squared + 7 minus 2 x squared + x
Myra combined 8 and Negative 2 to equal 6 x squared + x + 7.

Answer:
Yes! The given quadrilateral represents Parallelogram.
Reason: The given quadrilateral has opposite sides congruent.
Step-by-step explanation:
Given the quadrilateral with the four vertices.
Now in order to determine whether the given quadrilateral is a parallelogram or not, we need to check whether the opposite sides are congruent or not.It is clear that the given quadrilateral has opposite sides congruent.Therefore, the given quadrilateral represents Parallelogram.
Hence,
Yes! The given quadrilateral represents Parallelogram.
Reason: The given quadrilateral has opposite sides congruent.
Please look at the picture
Answer:
1.5
Step-by-step explanation:
Vertical angles are congruent so:
7x=8x-12
Subtract 7x from both sides:
0=8x-12
Add 12 to both sides:
8x=12
Divide both sides by 8:
x=1.5 or

what is half 7minutes and 24 seconds
Answer:
3 minutes and 42 seconds
Step-by-step explanation:
So I would convert that minute into seconds
7*60=420
So 420+24=444
Divide by 2
444/2=222
Now divide by 60 to convert it back to minutes
222/60= 3.7
3.7 minutes or
7/10*60=42
3 minutes and 42 seconds

12 = x(x - 4)
12 = x² - 4x
x² - 4x - 12 = 0
x² - 6x + 2x - 12 = 0
x( x - 6) + 2(x - 6) = 0
(x + 2)(x - 6) = 0
x = -2, 6
Since, measure of the sides can't be negative, x can not be negative.
Therefore, x = 6 will be the answer.

Answer:
x = 12
Step-by-step explanation:
We know that the integers are consecutive. This means that they can be written as:
x, x + 1, and x+2.
First Integer: x
Second Integer: x + 1
Third Integer: x + 2
It is also given that the sum of the first integer and twice the second is 80 minus three times the third.
Write as an equation:
First Integer + 2(Second Integer) = 80 - 3(Third Integer)
Substitute:
x + 2(x+1) = 80 - 3(x+2)
Multiply:
x + 2x + 2 = 80 - 3x - 6
Simplify:
3x + 2 = 74 - 3x
Add 3x to both sides of the equation:
6x + 2 = 74
Subtract 2 from both sides of the equation:
6x = 72
Divide both sides of the equation by 6:
x = 12
Let me know if you have any questions about my explanation!
Answer:
Smallest Integer = 12Step-by-step explanation:
According to question ,
• First Integer → x
• Second Integer → x + 1
• Third Integer → x + 2
Now question says that the sum of the first and twice the second is 80 minus three times the third that means ,
→ x + 2 ( x + 1 ) = 80 - 3 ( x + 2 )
→ x + 2x + 2 = 80 - 3x - 6
→ 3x + 2 = -3x + 74
→ 3x + 3x = 74 - 2
→ 6x = 72
→ x = 72/6
→ x = 12
Hence , value of x is 12 that means :
→ x = First Integer = 12
→ x + 1 = Second Integer = 13
→ x + 2 = Third Integer = 14
In all of these x is the smallest integer and hence 12 is the correct answer .

We move all terms to the left:
1/2(-1.4m+0.4)-(m+0.2)=0
Domain of the equation: 2(-1.4m+0.4)!=0
m∈R
We get rid of parentheses
1/2(-1.4m+0.4)-m-0.2=0
We multiply all the terms by the denominator

Wy multiply elements

Answer:
B: (x + 1) = (y - 2)²
Step-by-step explanation:
0 = y² - x - 4y + 3
We want to find the equation of the parabola in vertex form.
The format for the vertex form is;
y = a(x - h) + k
Where (h, k) is the coordinate of the vertex.
Thus, let's transform 0 = y² - x - 4y + 3 into the vertex form
Let's rearrange to get;
x - 3 = y² - 4y
Let's use method of completing the square to get right hand side;
x - 3 = (y - 2)² - 4
Add 4 to both sides to get;
x - 3 + 4 = (y - 2)²
(x + 1) = (y - 2)²
Which equation represents a line which is parallel to the line y=-4x-8y=−4x−8?
Answer:
Step-by-step explanation:
y = -4x - 8
Any equation with an equal slope will be parallel to the line
Example: y = -4x or y = - 4x + 8
As long as the equation has a different y-intercept and equal slope it will be parallel!
An equation of a line that is parallel to y = -4x - 8 would be in the form:
y = -4x + b
What is the equation of a line?In mathematics, the equation of a line is a formula that describes the relationship between the x and y coordinates of the points on the line.
Two lines are parallel if they have the same slope. The equation of the line y = -4x - 8 is in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.
From y = -4x - 8, we can see that the slope is -4. So, any line that is parallel to this line must also have a slope of -4.
Therefore, an equation of a line that is parallel to y = -4x - 8 would be in the form:
y = -4x + b
Where b is some constant value that determines the y-intercept of the line.
