Answer:
B
Step-by-step explanation:
In this case, we use variables to represent the the cost of the big and the smaller boxes. Let x be the selling price of the big boxes while y be the selling price of the bigger boxes.
The total selling price of the smaller boxes is 20x. The total selling price of the bigger ones is 12y.
Now we know he is making a profit of $1,300
Hence in equation form, all the information above can be represented as:
20x + 12y = 1,300

Answer:
The required equation in factored form is: [tex]\mathbf{y=-4(x+2)(x-1)}[/tex]
Step-by-step explanation:
In this question we need to find the equation of the graph in factored form.
The factored form will be: [tex]f(x)=a(x-r_1)(x-r_2)..[/tex]
where a is y-intercept and r₁, r₂ are x-intercepts
X-intercepts
When y=0, the values of x axis are known as x-intercepts
Y-intercepts
When x=0, the values of y-axis are known as y-intercepts.
Looking at the graph finding x-intercepts
When y=0 x=-2 and 1
So, we have
r₁ = -2
r₂ = 1
Looking at the graph finding y-intercepts
When x=0, y=-4
So, a = -4
Putting values in the formula we will get:
[tex]f(x)=a(x-r_1)(x-r_2)\\f(x)=-4(x-(-2))(x-1)\\f(x)=-4(x+2)(x-1)[/tex]
So, the required equation in factored form is: [tex]\mathbf{y=-4(x+2)(x-1)}[/tex]

For ax + by = c, solve for x.
Answer:
Step-by-step explanation:
ax + by = c
ax= c-by <------- Subtract by "by"
x= c-by/a <------ divide by a

y = -3x + 4
y = -7x
Submit Answer
Answer:
{y,x} = {7,-1}
Step-by-step explanation:
(-7x) + 3x = 4
- 4x = 4
4x = - 4
x = - 1
y = -7x
x = -1
y = -7(-1) = 7

What is an equation of the line that passes through the points (-2, 1) and (-8, 4)
and i need the answer quick please
Answer:
y= -1/2x
Step-by-step explanation:
y-y1/x-x1=y2-y1/x2-x1
y-1/x+2=-1/2
2y-2= -x-2
2y= -x-2+2
2y=-x
y=-1x/2„
Answer:
y= -1/2x

i need to know what the answer is we have to combine like terms 10-4+6(4-2)
Answer:
18
Step-by-step explanation:
Solve the separate part of the equation first
6(4) 6(-2) would equal 24-12
Add it back in to get: 10 - 4 + 24 - 12
-4-12 and 10+24 are the like terms so
10+24 = 34 and -4-12 = -16
Equation in the end: 34-16
Simplify that to: 34-16 = 18
Answer: 18
Step-by-step explanation: do ten minus four plus six and get twelve then dont subtract four from two add and you get 6 add that two gether and get eighteen

Kyle is buying a book online for $14.58. It is on sale for 10% off. What is the sale price with a 8.25% tax?
First, find the discount by finding 10% of $14.58. To do this, convert 0% into a decimal and multiply by $14.58.
14.58 x 0.1 = 1.458.
Since this a sale price, how much he is getting off, subtract from the total.
14.58 - 1.458 = 13.122.
We still have to find the sales tax. Solving is similar to finding the discount.
13.122 x 0.0825 = 1.082565.
Now, since it is a tax, add to the total.
13.122 + 1.082565 = 14.204565
Round to the nearest hundredth, and you have $14.20.
The sale price with after tax is $14.20.

Two groups of people need to get across a lake. The first group has 36 people. Its boats can carry 5 passengers. The second group has 24 people. Its boats can carry only 4 passengers.
Which group needs more boats?
follow the steps to solve the problem.
1. Group 1 is represented by the equation 5x = 36. Solve this equation for x. Show your work.
2. How many boats does group 1 need? Explain your answer.
3. Write and solve an equation to find how many boats group 2 needs. Show your work.
Answer:
Both groups need more boats
1.) 5x=36
36/5
=7.2 boats
2.) 7.2 but you can't split a boats nor can you decrease the amount of people so 8 boats.
3.)4x=24
24/4
=6 boats
