Answer:

11?

Step-by-step explanation:

Answer:

probaly about ten or 11 five four times is 20 and they are 22

Step-by-step explanation:

5 + 5 +5 +5=20

then you would do 2 x 4 since five is four times

2 x 4 = 8

so i would round up

Answer:

5

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

Answer: -2.55

Explanation: First add 10.2, and then the equation becomes -4x = 10.2.

Then, you just divide by -4 from both sides of the equation, and you get x = -2.55. :]

Answer:

21 - 4x

Step-by-step explanation:

Multiply 10 and 2 to get 20.

41 - 4x - 20

Subtract 20 from 41 to get 21.

21 - 4x

Answer:

D: SAS

Step-by-step explanation:

Answer:

the y intercept is 4

it represents that when it is 0 hours after sunrise the temperature is 4 degrees celcius

the slope is 4

it represents that every hour of sunrise the temperature increases by 4.

y = 4x + 4

Step-by-step explanation:

The

Answer:

a.: y intercept = 4

b.: the y intercept represents the temperature in degrees Celsius when no time has past.

c.: slope = 4

d.: the slope represents that for every hour that passes, the temperature rises 4 degrees.

e. y=4x + 4

Answer:

y=x-1

Step-by-step explanation:

The equation is currently in standard form which is a+b=y and slope-intercept is y=mx+b where m is the slope and b is the y-intercept. To change the form we must move the terms around using Properties of Equality.

First, subtract 1 from both sides

x-y-1=1-1

x-y-1=0

Then, add y to both sides

x-y-1+y=0+y

x-1=y

So that is the equation in slope-intercept form with a slope of 1 and a y-intercept of -1.

Answer:

y=x-1

Step-by-step explanation:

It is y=x-1 because first when we do ANYTHING first. We leave the y on the left side of the equation, since the slope y=mx+b has the y always on the left side. So we subtract x from both sides and we get -y=-x+1. We are NOT DONE yet, so after this, we divide both sides by -1. Why? This is because you cannot have a negative y. Dividing both sides by -1 you finally get y=x-1. If this is trouble some to read, I will also put how to solve the problem down below. :)

Let's solve for y.

x−y=1

Step 1: Add -x to both sides.

x−y=1+−x

−x

−y=−x+1

Step 2: Divide both sides by -1.

−y/ −1 = −x+1 /−1

y=x−1

Answer:

y=x−1

We already know that 0.5 of an hour, or half of an hour, is 30 minutes. We also know that 3 dozen equals 36. With this information, we can conclude that Natalie can make 72 cookies in one hour. 72 times 5 is 360. 360 divided by 12 is 30, so, Natalie can bake 30 dozen, or 360, cookies in five hours.

Answer:

Real numbers are not closed under cube root

Step-by-step explanation:

The cube of each real number is increasing as the real numbers increases, giving a functional or one to one relationship. Therefore, the cube roots of real number have also a one to one relationship.

Given that a cube root of a number, ∛x = y therefore, y³ = x, we have that all real numbers, excluding zero, have one cube root, and two complex and conjugate roots

For the real number, 8, we have the cube roots given as follows;

∛8 = 2

Also, ∛8 = -1 + √3i and -1 - √3i

Given that not all cube roots of 8 are real numbers we have that real numbers are not closed under cube root.

Answer:

35

Step-by-step explanation:

In such cases where there are two minuses, you join them and turn it into a plus sign. So therefore...

= 10 - ( -25 )

= 10 + 25

= 35

Step-by-step explanation: The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve.

Answer:

The answer would be 2x-3

Answer:

2 : 3

Step-by-step explanation:

4 : 6

Divide each by 2

2 : 3

Answer:

2:3

Step-by-step explanation:

4:6 is the same as 4/6.

And if we divide by 2 so we get 2/3 also known as 2:3.

Answer:

y=6x^2-30x-84

Step-by-step explanation:

Answer:

X = 21/2 = 10 1/2 or 10.5

Step-by-step explanation:

2x + 8:= 29

    -8.      -8

2x. = 21

divde both sides by 2

x = 21/2 = 10 1/2

Answer:

eqn of line

5x-y=-9

Step-by-step explanation:

Answer:

y = 5x + 9

Step-by-step explanation:

Assuming you require the equation.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 5 , thus

y = 5x + c ← is the partial equation

To find c substitute (- 1, 4) into the partial equation

4 = - 5 + c ⇒ c = 4 + 5 = 9

y = 5x + 9 ← equation of line
