Step-by-step explanation:
please mark as brainliest
Answer:
YES -13 is an integerStep-by-step explanation:
It is an integer because integers are whole numbers. This means that it doesn't include decimals, fractions, and irrational numbers. Even though not all negative numbers are integers, this one is, and that is because it is not a decimal, fraction, or irrational number.

Find the length of the shortest side ( rounded to 2DP) if the area of the rectangle is 28m^2
Answer:
4.39 to 2DP.
Step-by-step explanation:
x * (x - 2) = 28
x^2 - 2x = 28
Solving by completing the square:
(x - 1)^2 - 1 = 28
(x - 1)^2 = 29
x = +/-√29 + 1
x = 6.38516, -4.38516
x must be positive so it = 6.38516.
The shortest side = x - 2 = 4.385.

I sell cookies for $3 and muffins for $7. Yesterday, I made $129. I sold a total of 27 items. How many of each did I sell?
Answer:
You sold 15 cookies and 12 muffins
Step-by-step explanation:
So you're given that 1 cookie is sold for $3 and 1 muffin is sold for $7
You're also given that in total you made $129, and sold 27 items
Let's make equations from that, letting c stand for amount of cookies and m for amount of muffins.
3c + 7m = 129 (equation for amount of money made)c + m = 27 (equation for amount of items sold)Now we can use the second equation to find m:
c + m = 27
m = 27 - c
Not we can substitute m into the first equation to find c:
3c + 7m = 129
3c + 7(27-c) = 129 [substitute m for (27-c)]
3c + 189 -7c = 129 [distribute 7 into (27-c)]
-4c + 189 = 129 [combine like terms]
-4c = -60 [subtract 189 from both sides]
c = 15 [divide both sides by -4]
Now we can substitute c into the second equation to find m:
c + m = 27
15 + m = 27
m = 12

Enter the equation of the line in slope-intercept form.
The line parallel to y =
5/4x + 8 that passes through (−8, 0).
The equation of the line that passes through (−8, 0) is y = ???
Answer:
y = 5x/4 + 10
Step-by-step explanation:
If two lines are parallel, the slopes are equal
The equation of a straight line is y = mx + c
where m is slope and c is y-intercept
So in this case 5/4 is also the slope m of the second line
we can write the equation as;
y-y1 = m(x-x1)
y-0 = 5/4(x + 8)
y = 5x/4 + 10

Write the question, in slope-intercept form, for the line shown in the graph below:
Can some one pls help me in this math problem?
Answer:
The question, in the slope-intercept form will be:
[tex]y=1(x)+0[/tex]Step-by-step explanation:
Taking the two points on the line to find the slope
(0, 0)
(4, 4)
[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:0\right),\:\left(x_2,\:y_2\right)=\left(4,\:4\right)[/tex]
[tex]m=\frac{4-0}{4-0}[/tex]
[tex]m=1[/tex]
As the point-slope form is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope
substituting the values m = 1 and the point (0, 0)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-0=1(x-0)[/tex]
[tex]y=x[/tex]
As the slope-intercept form is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
so writing the equation in slope-intercept form
[tex]y=x[/tex]
[tex]y=1(x)+0[/tex]
Therefore, the question, in the slope-intercept form will be:
[tex]y=1(x)+0[/tex]what is the answer to -x+7=8
Answer:
-x+7=8
bring the 7 over.
to do so you must subtract 7 from itself (canceling it out), then also subtract it from 8.
now you have -x=1.
divide -x by -x (or -1) which just gives you positive x.
do the same to the 1 on the other side, giving you
x= -1

Write the numerator and denominator with a common denominator. Then divide the numerator by the denominator. To do this, multiply the numerator by the reciprocal of the denominator.
Step-by-step explanation:
Simplifying an expression involves breaking down the expression.
The true statement is: (a) Write the numerator and denominator with a common denominator. Then divide the numerator by the denominator. To do this, multiply the numerator by the reciprocal of the denominator.
The expression is given as:
[tex]\mathbf{\frac{\frac{5}{a -3} - 4}{ 2 + \frac{1}{a - 3}}}[/tex]
Start by writing the numerator and the denominator, with a common denominator
[tex]\mathbf{\frac{\frac{5}{a -3} - 4}{ 2 + \frac{1}{a - 3}} = \frac{\frac{5 -4a +12}{a - 3}}{\frac{2a - 6 + 1}{a - 3}}}[/tex]
Cancel out the denominators of both fractions (by dividing the numerators)
[tex]\mathbf{\frac{\frac{5}{a -3} - 4}{ 2 + \frac{1}{a - 3}} = \frac{5 -4a +12}{2a - 6 + 1}}[/tex]
So, we have:
[tex]\mathbf{\frac{\frac{5}{a -3} - 4}{ 2 + \frac{1}{a - 3}} = \frac{17 -4a }{2a - 5}}[/tex]
Hence, the correct option is (a).

Jana and Tim both sell cleaning products to local housecleaning services. When Jana orders from the manufacturer of the products she sells, she is given a 15% discount on her total purchase, and she must pay a $15 shipping fee. Each of Tim's orders to his manufacturer is charged at 85% of the full purchase price of the products, and he pays a $4 handling fee, plus $11 for shipping. Choose ALL of the statements that are true. When Jana and Tim purchase products having the same total value, their costs for the purchases will always be the same. Jana and Tim will never spend exactly the same amount on purchase orders to their manufacturers. Jana and Tim will only spend the same amount on purchase orders to their manufacturers when they each order products with a total purchase value of $100. If Jana switches to Tim's manufacturer for her product purchases, her cost will decrease. If Tim switches to Jana's manufacturer for his product purchases, his cost will remain the same.
Answer: Jana and Tim will only spend the same amount on purchase orders to their manufacturers when they each order products with a total purchase value of $100.
Step-by-step explanation:
Jana and Tim would only be incurring same amount when both total purchase is to a value of $100. This is so because by purchasing a goods worth same amount, they both end up incurring $15 dollar additional cost. Jana would spend $15 on shipping her goods, while Tim would pay $4 Handling fees and $11 dollar shipping fee which would also amount to $15. What this means is total spent for both Jana and Tim would amount to $115 each.

m= yo
your slope
Step-by-step explanation:
Answer:
The equation of the line that passes through the points (-1,8) and (2,-4) is:
[tex]y=-4x+4[/tex]Step-by-step explanation:
Given the points
(-1,8)(2,-4)[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-1,\:8\right),\:\left(x_2,\:y_2\right)=\left(2,\:-4\right)[/tex]
[tex]m=\frac{-4-8}{2-\left(-1\right)}[/tex]
[tex]m=-4[/tex]
As the point-slope form of the line equation is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope.
substituting the values m = -4 and the point (-1,8)
[tex]y-\(8\right=-4\left(x-\left(-1\right)\right)[/tex]
[tex]y-8 = -4(x+1)[/tex]
Add 8 to both sides
[tex]y-8+8=-4\left(x+1\right)+8[/tex]
[tex]y=-4x+4[/tex]
Therefore, the equation of the line that passes through the points (-1,8) and (2,-4) is:
[tex]y=-4x+4[/tex]
