help me please!! Slope

Answer:

Option (c) is correct.

Step-by-step explanation:

Given equation is :

[tex]s=\dfrac{a+b+c}{3}[/tex]

The equation can be solved for a as follows :

Step 1.

Cross multiply the given equation

[tex]3s=a+b+c[/tex]

Step 2.

Now subtract b on both sides

3s-b = a+b+c-b

3s-b = a+c

Step 3.

Subtract c on both sides

3s-b-c=a+c-c

⇒ a=3s-b-c

The statement that is true for Darpana is " In step 3, she needed to subtract c rather than divide".

Answer:

the correct answer is c

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

First you write out your inequality:

[tex]2b-7\geq -14+2b[/tex]

So first we will subtract 2b on both sides:

[tex]-7\geq -14[/tex]

Since they both canceled out each other we are now left with [tex]-7\geq -14[/tex]

So anyways let's add 7 to both sides:

[tex]0\geq -7[/tex]

I know this might be confusing but the answer is all real numbers.

Tip: Real numbers are, in fact, pretty much any number that you can think of. This can include whole numbers or integers, fractions, rational numbers and irrational numbers.

Answer

$60500

Step-by-step explanation:

$50,000÷100=500           1%=500

500x21(3%x7)=10500

$50,000+$10500=$60500

Step-by-step explanation:

y-y1=m(x-x1)

y+7=2(x+5)

y+7=2x+10

2x-y=-3

Answer:

-3 = x

Step-by-step explanation:

4 (2x + 3) = 4x + 24 + 6x – 6

8x + 12 = 10x + 18

12 = 2x + 18

-6 = 2x

-3 = x

Answer:

x=10

Step-by-step explanation:

5x-6=44

Add 6 to each side

5x-6+6 = 44+6

5x = 50

Divide by 5

5x/5 = 50/5

x=10

Easy buddy...

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

Subtract the sides of the equation plus 15

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

[tex]5x = 3x + 22[/tex]

Subtract the sides of the equation minus 3x

[tex]5x - 3x = 22[/tex]

[tex]2x = 22[/tex]

Divided the sides of the equation by 2

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

[tex]x = 11[/tex]

Algebraic notation is a method for recording and describing the moves in a game of chess. It is based on a system of coordinates to uniquely identify each square on the chessboard.

Answer:

The answer would be A. -4

Step-by-step explanation:

If you right it out like x-6=5(x+2), then you distribute the 5, you get: x-6=5x+10. Then subtract x from both sides, you get: -6=4x+10. Subtract 10 from both sides, you get: -16=4x. The all you have to do is divide both sides by 4, and you get: -4=x

answer: you would just substitute all of the values you see for b into the equation where there's a b

Answer:

55; 64; 73

Step-by-step explanation:

In the table, they provide a b value. Basically, you plug in the value of b they give you into the expression n = 9b + 19

if b = 4:

n = 9(4) + 19

n = 36 + 19

n = 55

if b = 5:

n = 9(5) + 19

n = 45 + 19

n = 64

if b = 6:

n = 9(6) + 19

n = 54 + 19

n = 73

Check your work with the last numbers in the table. They say the value of n = 82 when b = 7 so try it

if b = 7:

n = 9(7) + 19

n = 63 + 19

n = 82

Work is correct

Try not to overthink it ^-^

Answer:

40 and 28

Step-by-step explanation:

We have two unknown numbers, so let's call them x and y for now.

We know the sum of the two numbers is 68, and the difference is 12, so let's substitute those two numbers for x and y:

x+y=68

and

x-y=12

Because both of these systems are true, we can take both these equations and combine them, by adding each side of one equation with the corresponding side of the other.

So we have:

(x+y)+(x-y)=(68)+(12)

2x=80

x=40

Now we know one of the numbers, x, is equal to 40, so now we can plug that number back into one of the two original equations, x+y=68 or x-y=12. I'll choose x-y=12.

After plugging in x, we get:

40-y=12

-y=-28

y=28

So now we have figured out x and y, which are 40 and 28.

the answer is 168

Step-by-step explanation:

you times 4 by 2 you get 8.

now you got to times 4 by 40 and you get 160

now you add 8 to 160 you will get 168

Answer:

Greatest Common Factor of 24 and 34 Greatest common factor (GCF) of 24 and 34 is 2.

Step-by-step explanation:

Step-by-step explanation:

x^3-8 = 0

or, x^3 = 8

or, x = 8×(1/3)

or, x = 2

All solutions to the equation are x = 2,  -1 + i√3, and -1 - i√3 two roots are complex and one root is real.

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

We have:

x³ - 8 = 0

Using identity:

a³ - b³ = (a - b)(a² + ab + b²)

(x - 2)(x² + 2x + 4) = 0

x = 2

x² + 2x + 4 = 0

Using quadratic formula:

[tex]\rm x = \dfrac{-2 \pm\sqrt{2^2-4(1)(4)}}{2(1)}[/tex]

x = -1 ± i√3

Thus, all solutions to the equation are x = 2,  -1 + i√3, and -1 - i√3 two roots are complex and one root is real.

Answer:

4^1 + 17 = 21 , which is divisible by 3. 4^k + 17 and 3 * 4^k are both divisible by 3, so 4^k + 17 + 3 * 4^k is divisible by 3 as well. 3 * (4^n + 17) would be divisible by 9

Answer:

-10 degrees

Step-by-step explanation:

at noon the temp was -10. -10 + 12 = 2 and that is at 4 o'clock 2- 6 hours ( time until 10 pm) x 2. 2 - 12 = -10.

Answer: 0º F.

Step-by-step explanation:

Noon = 12 pm

At Noon it was -10º F, over the next 4 hours it went up to 12º F.

Noon + 4 hours = 4 pm

The temperature dropped 2º F every hour until 10 pm which means for 6 hours the temperature dropped.

6x2º F = 12º F which means the temperature dropped by 12º F.

12º F - 12º F = 0º F
