Find slope can anyone give me a step by step

Answers

Answer:

slope is 6/1 (or 6)

Step-by-step explanation:

your y-intercept is 3, so that means the point will be (0,3).

from there, you can start plotting points. up 6, over 1 (to the right)

the equation for a line is y=mx+b, so whatever number is in m will always be your slope, and whatever number is in b will be your y intercept

The answer is D

Step-by-step explanation:

(4x6)^3

(24)^3=13,824

when you multiply 4^3 with 6^3 you get the same answer of 13,824

Answer:

Answer=D

Step-by-step explanation:

(for powers outside a bracket it splits in the numbers inside the bracket)

(4×6)^3

=([tex]4^{3}[/tex]×[tex]6^{3}[/tex]) as in D

To proof

-if we multiply them first we will get 24 and that to the power of three will equal to 13824.

-if we did as in the answer so,

[tex]4^{3}[/tex]×[tex]6^{3}[/tex]

=64×216

=13824

they are equal to each other 13824=13824 so answer D is correct.

C is the circumcenter of PQR
PC=3x+7, RC=5x-15 and QC=51-x.
what does RC equal?

Answers

Answer:

[tex] RC = 40 [/tex]

Step-by-step explanation:

Given:

PC = 3x + 7,

RC = 5x - 15,

QC = 51 - x.

Required:

measure of RC

SOLUTION:

Given that C is the circumcenter of ∆PQR, therefore, vertices P, Q, and R are equidistant from C.

So therefore,

[tex] PC = RC = QC [/tex]

Let's find the value of x using:

[tex] PC = RC [/tex]

[tex] 3x + 7 = 5x - 15 [/tex] (substitution)

Collect like terms

[tex] 3x - 5x = -7 - 15 [/tex]

[tex] -2x = -22 [/tex]

Divide both sides by -2

[tex] x = \frac{-22}{-2} [/tex]

[tex] x = 11 [/tex]

Find the measure of RC

[tex] RC = 5x - 15 [/tex]

substitute x = 11 into the equation

[tex] RC = 5(11) - 15 [/tex]

[tex] RC = 55 - 15 [/tex]

Meandre has 8 pints of milk. If he drinks ¼ of a pint of milk each day, how long will the 8 pints of milk last him?

Answers

Answer:

16 days

Step-by-step explanation:

1/4 = 0.25

8 divied 32

In multiplacation

8 time 4 = 32

8 pints of milk will last for 32 days.

What is Division?

Division is one of the operation in mathematics where number is divided into equal parts as that of a definite number.

Given that,

Total amount of milk Meandre has = 8 pints

Amount of milk drinking in 1 day = 1/4 pint

We have to calculate the number of days that 8 pints of milk will last.

Let x be the required number of days.

Using the concept of proportion,

(1/4) / 1 = 8 / x

1/4 = 8 / x

x = 8 × 4

x = 32

Hence total number of days that 8 pints of milk will last is 32 days.

Many of the insects, snails, birds, mice, and other animals found in these communities rely on Spartina for food, nest building materials, protection for their young, etc. The roots of Spartina also form dense mats that hold together soil in these ecosystems. Many species that live in Spartina salt marshes cannot survive outside of these unique ecosystems.
