Answer:

Alisha might have not taken respective input values with the output values and the correct slope is 3.

Step-by-step explanation:

The general form of a linear relationship is given by the equation

[tex]y = mx+b[/tex]

Here m is the rate of change of the linear relationship which is calculated as:

[tex]m = \frac{change\ in\ y}{change\ in\ x}[/tex]

Change in y is given by the difference of two outputs and x is given by difference of two inputs

So taking the set of outputs and inputs

(1,2) and (2,5)

[tex]m = \frac{5-2}{2-1}\\m = \frac{3}{1}\\m = 3[/tex]

Alisha might have not taken respective input values with the output values and the correct slope is 3.

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

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

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:

(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.

Required standard form is 0.000009054.

What is value of 9.054 x 10^-6 in standard form ?

Some examples of standard form of Mathematics,

Example -1:

[tex]0.5 \times {10}^{2} \\ = 0.5 \times 100 \\ = 50[/tex]

Example-2 :

[tex]0.254 \times {10}^{ - 2} \\ = \frac{0.254}{ {10}^{2} } \\ = \frac{0.254}{100} \\ = 0.00254[/tex]

Example-3 :

[tex]3.3548 \times {2}^{2} \\ = 3.3548 \times 2 \times 2 \\ = 13.4192[/tex]

Example -4 :

[tex]5.55 \times {3}^{2} \\ = 5.55 \times 3 \times 3 \\ = 48.95[/tex]

So,we can say that standard form means simplest form.

Here given,

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.

Answer:

The cost of 15 potatoes is $7.50

Step-by-step explanation:

The potatoes are sold at a rate of $0.5 per potato.

1. Given Amanda can only spend $5 on potatoes at that price, she can buy at most $5 / 0.5 = 10 potatoes.

Amanda can buy at most 10 potatoes

2. Sam wants to buy 15 potatoes at that very same price. The cost of 15 potatoes is:

15 * $0.5 = $7.50

The cost of 15 potatoes is $7.50

Answer:

6+7+4+10+4 = 31. The answer is B. I am not sure.

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.
