Is (1, -1) a solution to y = 3x - 4?
Explain.

Answers

(1,-1) is a solution to y=3x-4 because when we plug in 1 for x in the equation we get y=-1. Since x is 1 and y is -1 we can see that the coordinate points (1.-1) are a solution to y=3x-4.

4. John is packing books into boxes. Each box can hold either 15 small books or 8
large books. He needs to pack at least 35 boxes and at least 350 books, Write a
system of linear inequalities to represent the situation

Answers

Answer:

Your system of inequalities is:

x + y ≥ 35

15x + 8y ≥ 350

Step-by-step explanation:

Let x = number of boxes of small books and let y = number of boxes of large books.

 Since John needs to pack at least 35 boxes:

 (number of boxes of small books) + (number of boxes of large books) (is at least) 35

x + y ≥ 35

Since John needs to pack at least 350 books:

 (number of small books packed) + (number of large books packed) (is at least) 350

(number of small books per box)(number of boxes of small books) + (number of large books per box)(number of boxes of small books) ≥ 350

15x + 8y ≥ 350

The ratio of Braydon's number of laps he ran to the time he ran is 6:2. The ratio of Monique's number of laps she ran to the time she ran is 104. Explain why these ratios are not in a proportional relationship.​

Answers

Answer:

They are not in a proportional relationship because Monique's number and time isnt a proportion. Instead it is a whole number. Like Braydon's his is 6:2 that is the correct way to write it.

Step-by-step explanation:

The ratio is not proportion.

What is ratio and proportion?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

Given:

The ratio of Braydon's number of laps he ran to the time he ran is 6:2.

The ratio of Monique's number of laps she ran to the time she ran is 10:4.

The simplest for Braydon is = 6/2 = 3/1

and, the simplest form for Monique = 10/4 = 5/2

As, 3/1 ≠ 5/2

So, the ratio is not proportion.

Answer:

The answer is $1,875

Step-by-step explanation:

1. I just divided $60,000 by 2 and $1,500 by 2 and got $30,000:$750

2. I realized I needed to do more so I divided again and got $15,000:$375. Next I added it to the question $60,000 + $15,000 = $75,000

3. So then $1,500 + $375 = $1,875

determine the vertex of y=4(x-25)2+ 91

Answers

Answer:

             (25, 91)

Step-by-step explanation:

y = a(x - h)² + k        ← vertex form of  the equation of the parabola with vertex (h, k)

So y = 4(x - 25)² + 91  means:

a = 4

x - 25 = x - h    ⇒  - 25 = - h  ⇒  h = 25

+ 91 = + k     ⇒    k = 91

Therefore vertex is:

If f(x)=2x^3+4x^2, find f(-3)

Answers

Answer:

f(-3) = -18

Step-by-step explanation:

f(x)=2x^3+4x^2, find f(-3); let's rewrite

f(x) = 2[tex]x^{3}[/tex] + 4[tex]x^{2}[/tex]; substitute -3 for x

f(-3) = 2[tex](-3)^{3}[/tex] + 4[tex](-3)^{2}[/tex]; do the exponents

f(-3) = 2(-27) + 4(9); multiply and add

f(-3) = -54 + 36 = -18

The value of the function  f(x) = 2x³ + 4x² at f(-3) is - 18.

What is a function?

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given, A function f(x) = 2x³ + 4x².

Now, The value of the function f(-3) can be obtained by replacing

x with - 3.

Therefore, f(-3) = 2(-3)³ + 4(-3)².

f(-3) = 2×-27 + 4×9.

f(-3) = - 54 + 36.

f(-3) = - 18.

Can someone put this into vertex form?
y=x2+24x-15

Answers

Answer:

The vertex form of y = x² + 24x - 15 is y = (x + 12)² - 159

Step-by-step explanation:

The vertex form of the quadratic equation y = ax² + bx + c is

y = a(x - h)² + k, where

a is the coefficient of x²(h, k) are the coordinates of the vertex pointh = [tex]\frac{-b}{2a}[/tex] , where b is the coefficient of xk = y at x = h

Let us use the facts above to solve the question

y = x² + 24x - 15

∵ a is the coefficient of x² and b is the coefficient of x

a = 1 and b = 24

∵ h is the x-coordinate of the vertex point

∵ h = [tex]\frac{-b}{2a}[/tex]

→ Substitute the values of a and b to find h

∴ h = [tex]\frac{-24}{2(1)}=\frac{-24}{2}[/tex]

h = -12

→ To find k substitute y by k and x by h

∵ y = k and x = h

∴ k = (-12)² + 24(-12) - 15 = 144 - 288 - 15

k = -159

∴ The coordinates of the vertex point are (-12, -159)

→ Substitute the values of a, h, and k in the vertex form above

∵ y = 1(x - -12)² + (-159)

→ Remember (-)(-) = (+) and (+)(-) = (-)

y = (x + 12)² - 159

The vertex form of y = x² + 24x - 15 is y = (x + 12)² - 159

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.

It is given that on Monday, the temperature was 43°F. On Tuesday, the temperature increased by 6°F. On Wednesday, the temperature decreased by 13°F.

The overall change in temperature from Monday to Wednesday is found as,

=  43°F  + 6°F  - 13°F

= 24 °F

Thus, if on Monday, the temperature was 43°F. On Tuesday, the temperature increased by 6°F the overall change in temperature from Monday to Wednesday will be  24°F.

Step-by-step explanation:

answer pleaseeeeeeeeeeeeeeeee

Answers

You can answer this by plugging in the x values given in the chart.

For example let’s look at the first column where x is given to equal -1
If we know that x=-1 then we can substitute that for x in the given equation y= 3x+2 so now it looks like
y=3(-1)+2

The 3 and the -1 are spectated only by parenthesis meaning they are multiplied. So now it look like this:
y=-3+2
Now just add these terms together
y=-1
Now you know what goes in the y box under -1.
You can repeat this for each x value.

Let’s do one more, the box that has 0 In it. Remember this means x=0 so 0 can be put anywhere in the equation you see x.
Y=3(0)+2
Anything times 0 is zero
So you just have: y=0+2
So y=2
This would go in the box under the 0.
