Answer:

The point (Negative 4, negative one-fourth) is a solution to this system of equations

Step-by-step explanation:

y = 8x - 2

y = - 4x - 5

y - 8x = - 2 - - (1)

y + 4x = - 5 - - - (2)

Subtract 1 and 2

-8x - 4x = - 2 - (-5)

-8x - 4x = 3

-12x = 3

x = - 1/4

y = 8(-1/4) - 2

y = - 2 - 2

y = - 4

(-1/4, - 4)

hello! your answer is D! :)

Step-by-step explanation:

i took the test.

Answer:

They need to make at least 12 batches.

Step-by-step explanation:

First, we need to find how many cookies in total, so we multiply 70 by 4.

70*4 = 280.

Secondly, 1 batch makes 2 dozen cookies, or technically 24 cookies. So we need to find how many batched with 280 divided by 24. This results in 11.6 repeating. But if you round it up, you get 12.

Time to check:

12 * 24 = 288. So it's the amount of cookies needed with 8 remaining.

Hope this helps.

Answer:

t = 4

Step-by-step explanation:

In step two, instead of multiplying by -6 on both sides, you need to divide by -6 to isolate t.

-6t = -24

÷-6    ÷-6

t = 4

When you multiply by -6 on both sides, the equation would be 36t = 144, which is not what we want. The opposite of multiplication is division, and in order to get the answer, you divide by the number multiplied.

Wait u gave the same equation twice, do u mind checking back to it?

Answer:

9π cm³

Step-by-step explanation:

We require to find the height (h) of the cylinders

The volume (V) is calculated as

Ah ( A is the base area and h the height ), then

3πh = 18π ( divide both sides by 3π )

= 6

Then the height of the smaller cylinder = 6 - 3 = 3 cm

3π × 3 = 9π cm³ ← volume of smaller can

Answer:

15 tables

Step-by-step explanation:

75/5 = 15

Answer:

There are 15 tables in the library.

Step-by-step explanation:

You know this because you know the library holds 75 people and you know how many people can sit at a table so to find the answer you divide 75 by 5 and you get 15. To check this you can multiply 15 by 5 and you will get 75.  

Answer:

7

Step-by-step explanation:

We need to plug in -1 for x. Here's what we get:

[tex]-5(-1)+2[/tex]     multiplying two negative numbers gives us a positive number

[tex]5+2[/tex]

= 7

Answer:

g(-1) = 7

Step-by-step explanation:

this is a function, when it says f(x) or g(x), whatever, and then gives, in this case g(-1), it wants you to substitute -1 into all the x values.

Therefore, our equation is g(-1)= -5 (-1) +2

this simplifies to g(-1)= 7

Answer:

A.

Answer:

D

Step-by-step explanation:

Ed's answer is correct but I would have just multiplied each side by the reciprocal of 2/3 which is 3/2, which will isolate 'm'

m = 1/4 x 3/2

m = 3/8

Answer:

324

Step-by-step explanation:

c = (b/2)²=(-36/2)²=(-18)²=324

Answer:

y = |x+1.5|

Step-by-step explanation:

Start with the graph of y = |x|. To shift it left by 1.5 units, replace x with x+1.5.

So Hazel is correct

Answer:

B is the correct answer

Step-by-step explanation:

Since it gets rid of the y so you could find the x and then work around to find the Y.

Answer:

Multiply the first equation by 3.

Step-by-step explanation:

Answer:

The system of inequalities can be used to find the values of x and y is

z ≥ 40

y ≥ 40

x+y ≥ 80

x+y ≤ 160

Step-by-step explanation:

Let z represent the number of pounds of potatoes and y represent the number of pounds of onions.

In mathematics at least means equal or greater than ,

So applying this property we get

z ≥ 40 →   at least 40 pounds of potatoes

y ≥ 40 → at least 20 pounds of onions

x+y ≥ 80 → combined must be at least 80 pounds

x+y ≤ 160 →  but must not exceed 160 pounds.

So the correct choice is B

Answer:

[tex]h(x) = -4(x - 2)(x + 2)[/tex]

Step-by-step explanation:

Given

[tex]h(x) = -4(x - 2)(x + 2)[/tex]

[tex]h(x) = -2(2x^2 - 8)[/tex]

[tex]h(x) = -4(x^2 - 4)[/tex]

[tex]h(x) = -4x^2 + 16[/tex]

Required

Which shows the zeros of h(x)

To determine the zeros of a function, the function must be written as:

[tex]h(x) = n(x \± a)(x \± b)[/tex]

Where

[tex]n \ne 0[/tex]

[tex]\± a,\± b[/tex] are the zeros

Of options (a) to (d), only (a) is written in the form:

[tex]h(x) = n(x \± a)(x \± b)[/tex]

i.e.

[tex]h(x) = -4(x - 2)(x + 2)[/tex]

Other options do not show the zeros
