Answer:

Step-by-step explanation:

9/3 = 3

3+4 = 7

The answer is 7!

Answer:

7

Step-by-step explanation:

First, plug in m.

9/3+4

Because this equation has multiple operations, we need to use the order of operations, aka PEMDAS. It stands for Parentheses, Exponents, Multiplication/Division, and Addition/Subtraction. First in the order of operations that we have in this equation is multiplication/division. So, we need to divide 9/3 before adding.

9/3=3

The equation is now simplified to 3+4, which is 7.

Hope this helps! Have a great day :D

Answer:

X-intercept- ( 3/7,0)

Y-intercept- (0,-3)

Step-by-step explanation:

To find the y-intercept(s), substitute in  0 for x and slove for y

y=7(0)-3

simplify y=-3

to find the x-intercept(s), substitute in  0 for y and slove for X  

0=7x-3

rewrite equation- 7x-3=0 and slove

which would equal 3/7

x = 7 or x = -8

Step-by-step explanation:

3|2x + 1| = 45

Divide both sides by 3.

|2x + 1| = 15

Separate into a compound equation.

2x + 1 = 15 or 2x + 1 = -15

2x = 14 or 2x = -16

Answer:

610 feet

Step-by-step explanation:

From the question :

1 scarf = 2.5 yards of yarn

84 scarves = x yards

Cross Multiply

1 scarf × x yards = 84 × 2.5 yards

x yards = 210 yards

Hence, 84 scarves require 210 yards

Converting yards to feet

1 yard = 3 feet

210 yards = x feet

x feet × 1 yard = 210 yards × 3 feet

x feet = 210 yards × 3 feet/1 yards

x feet = 610 feet

Hence, if Janet wants to make 84 scarves, she need to buy 610 feet of yarn

Answer:

y = -19

Step-by-step explanation:

-3 = 12y -5(2y - 7)

distribute -5 to (2y -7)

-3 = 12y - 10y + 35

subtract 35 from both sides and simplify

-38 = 2y

divide both sides by 2 to isolate y

-19 = y

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given  a pair of alternate exterior angle of 4x + 24 and 8x, we are to find the value of x that will make m and n parallel.

Alternate exterior angles are equal, hence;

4x + 24 = 8x

24 = 8x - 4x

24 = 4x

Rearrange

4x = 24

Divide both sides by 4

4x/4 = 24/4

x = 6

Hence the value of x required is 6

Answer:

4t + 8

Step-by-step explanation:

t + 3t = 4t

4t + 8

Answer:

4t+8

Step-by-step explanation:

If you look at your equation t+8+3t you will notice how you have two t parts

part 1: t

part 2: 3t

Since they have the same variable or letter you are able to combine them. When you add them together you get 4t.

Then you just put your 8 back on to the equation! 4t+8

Area = 4.84 cm^2 (centimeters squared)

Answer:

(0 , 25)

Step-by-step explanation:

y = 4x + 25 is our equation.

The formula used is y = mx + b where:

m = slope

x = independent variable

b = constant/y - intercept

Based on that knowledge we can tell that 25 is our y intercept.

Answer:

C. The market price of the bonds is more stable than the price of the company's stock.

Step-by-step explanation:

In the context, Sam bought some bonds at the market price from Grath Oil and also invested in buying corporate shares which paid a dividend of $3.10 for each share annually for a period of ten years.

At present the market value of the bonds of Grath Oil is more. The market price of the bond is the amount of the money to be paid in an open market to buy a bond.

So the bond's market price is much more stable than the price of the company's stock. It is riskier to invest in company stocks.

Answer:

Whereby the counting numbers Sam wrote down are 12 and 11, we have;

a) The number of natural numbers = 2

b) The number of digits = 4

c) The sum of the digits is 5

Step-by-step explanation:

The natural numbers are also known as the counting numbers or the ordering numbers and includes positive whole numbers from 1 and above

b) A digit is a number from 0 to 9, which can be used singly or combined to form a number

There are two digits each in 12 and 11, therefore, there are a total of 4 digits in both numbers

c) The sum of all the digits is given as follows;

The sum of the digits = 1 + 2 + 1 + 1 = 5.

Answer:

y = - 8x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

Here m = - 8 and (0, 3) → c = 3

y = - 8x + 3 ← equation of line

Answer:

(x + 5)^2 = (5 - 3)^2

Step-by-step explanation:

Given the equation;

x^2 + 10x + 22 = 13

We have;

x^2 + 10x = 13 - 22

x^2 + 10x = -9

Adding half of 10 to both sides and completing the square as usual, we have;

(x + 5)^2 = 5^2 + (-9)

(x + 5)^2 = (5 - 3)^2

The rewritten equation, after completing the square, is

(x - 3/2)² = -79/4.

To rewrite the equation x² + 10x + 22 = 13x as (x + c)² = d or (x - c)² = d, we need to complete the square on the left side of the equation.

Step 1: Move the constant term (22) to the right side of the equation:

x² + 10x = 13x - 22

Step 2: Move all terms involving x to the left side:

x² + 10x - 13x = -22

x² - 3x = -22

Step 3: Take half of the coefficient of x (-3) and square it.

To both sides of the equation, add the following value:

x² - 3x + (-3/2)² = -22 + (-3/2)²

Simplifying:

x² - 3x + 9/4 = -22 + 9/4

Step 4: Make the right side of the equation simpler:

-22 + 9/4 = -88/4 + 9/4 = -79/4

Step 5: The left side of the equation should now be written as a perfect square trinomial:

(x - 3/2)² = -79/4

Therefore, the rewritten equation, after completing the square, is

(x - 3/2)² = -79/4.
