Answer:
2x - 3y + 8
Step-by-step explanation:
If you combine like terms
(In this case "y" and "-4y")

Henry has q5 lawns mowed out of total 60 lawns what percent of the laws does. Henry still have to mow
Answer:
Henry still has to mow 75% of the laws.
Step-by-step explanation:
It is given that Henry has 15 lawns mowed out of a total of 60 lawns.
We need to find: What percent of the lawns do Henry still have to mow?
Henry has 60 lawns in total.
He mowed 15 out of them.
The percentage of lawns mow = [tex]\frac{15}{60} \times 100=25 \%[/tex]
Henry mowed 25% of total lawns.
The percent of laws still have to mow = 100%-25%
The percent of laws still have to mow = 75%
Hence, Henry still has to mow 75% of the laws.

Answer:
Second Choice.
Step-by-step explanation:
The shifting of graph depends on value of b.
[tex]y = mx + b[/tex]
If b > 0, the graph shifts up.
If b = 0, the graph passes origin point.
If b < 0, the graph shifts down.
The only thing that's matter if the graph shifts up or down is about if the value of b is in negative or positive.

Find angle x and y. Please show step by step process.
Answer:
x = 60, y = 25
Step-by-step explanation:
Δ ABC has 3 congruent sides and is equiangular, thus
the 3 angles are congruent, all 60°
x = 60
∠ ABC and ∠ CBD are adjacent and supplementary, sum to 180° , then
∠ CBD = 180° - 60° = 120°, so
y = 180 - (120 + 35) = 180 - 155 ← sum of angles in triangle
y = 25

The shoe store bought a pair of shoes for from the wholesaler for $45, and then marked them up 80%.
How much $ did the shoes get marked up by?
how much did the shoe company charge for the shoes?
Answer:
$81
Step-by-step explanation:
You need to divide 45 by 10 to get 10% of 45. 10% of 45= 4.5. Then, multiply 4.5 by 8 to get 80% of 45. Then, add 36 to 45 to get 81 dollars final price.

9x+y=2
−4x−y=−17
Answer: x = -3 y = 29
Step-by-step explanation:
9x + y = 2
-4x - y = -17
5x = -15
Divide both sides by 5
x = -3
9x + y = 2
Substitute -3 for x
9 (-3) + y = 2
-27 + y = 2
Add 27 to both sides
y = 29

What is the gross profit margin?The gross profit margin is a profitability raio. Profitability ratios measures the efficiency with which a company generates profit from its asset. Gross profit margin measures the return on sales.
Gross profit margin can be calculated by dividing the gross profit (difference between revenue and cost of goods sold) by revenue (Net sales). It could be expressed as a percentage by multiplying by 100.
Therefore, Gross profit margin = (gross profit ÷ net sales) x 100
Gross profit = $3,320
Net sales = $4,350
Gross profit margin = ($3,320÷$4,350) * 100
0.763 * 100 = 76.3%
4,350 - 3,320 = 1030
That would be 870 dollar.

Why do the roots of a quadratic equation have the opposite sign of the factors of a quadratic equation
Answer:
To find the roots of the quadratic equation we set the factors of the quadratic equation equal to 0.
Step-by-step explanation:
Consider the provided information.
Roots of the equation is x-intercepts or zeros of the given equation.
So, By definition, the value of The y-coordinate is zero for points situated on the x-axis.
Thus, we can find the roots of a quadratic function, by putting f (x) = 0.
Now, let (x-a)(x-b) is the factor of any quadratic equation.
To find the roots of the quadratic function we will put our factor equal to 0.
[tex](x-a)(x-b)=0[/tex]
Now by the zero product property either x-a=0 or x-b=0
[tex]x-a=0[/tex] then [tex]x=a[/tex]
or
[tex]x-b=0[/tex] then [tex]x=b[/tex]
So, we can say that to find the roots of the quadratic equation we set the factors of the quadratic equation equal to 0.

Starbucks sells their coffee for $3.36 for 24 ounces
OR
Circle K sells their coffee for $2.40 for 16 ounces
Which is a better buy and by how much?
Answer:
Starbucks by 1 cent difference.
Step-by-step explanation:
Divide: 3.36 divided by 24 to find Starbucks. You get 14 cents per ounce
Divide: 2.40 divided by 16 to find Circle K. You get 15 cents per ounce
Compare: Starbucks is cheaper by 1 cent.
Answer:
starbucks is a better by because they each sell one ounce for the same price. from starbucks you get more ounces for the same price as you would at circle k
Step-by-step explanation:
starbucks: 24 / 336 = $0.07
1 ounce sells for about $0.07
circle k: 16 / 240 = 0.066 = (rounded) 0.07
1 ounce sells for about $0.07
