Evaluate 9/m + 4 when m = 3
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.

Alisha used the Given table to find the slope of a linear relationship . Find her Error and correct it :
Alisha's Answer:
The Slope ( m ) = 6
Answer:
Please mark me as a brainlist.............
Thank you.....
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.

The corner market sells potatoes at a rate of 1/2 dollars per potato.
1. Amanda is only able to spend $5 on potatoes. What is the most number of potatoes she can buy?
2. Sam wants to buy 15 potatoes. How much will that cost him?
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
-3=12y-5(2y-7). Solve for y
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

X 2 +10x+22=13x, squared, plus, 10, x, plus, 22, equals, 13 1) Rewrite the equation by completing the square. Your equation should look like (x+c)^2=d(x+c) 2 =dleft parenthesis, x, plus, c, right parenthesis, squared, equals, d or (x-c)^2=d(x−c) 2 =dleft parenthesis, x, minus, c, right parenthesis, squared, equals, d.
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.

Sam wrote down the counting numbers from 12 to 11 (including)
a) How many natural numbers did she write?
b) how many digits?
c) what is the sum of all the digits?
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.

Step-by-step explanation:
y = 4x + 25 is our equation.

m = slope
x = independent variable
b = constant/y - intercept
Based on that knowledge we can tell that 25 is our y intercept.

An image shows three groups of three tenths and two hundredths.
Which of the following explains the mistake Jill made?
A.
Jill used 3 groups of 3 tenths and 2 hundredths rather than 4 groups.
B.
Jill used groups of 3 tenths and 2 hundredths rather than groups of 4 tenths.
C.
Jill used 3 groups of 3 tenths and 2 hundredths rather than 2 groups.
D.
Jill used groups of 3 tenths and 2 hundredths rather than groups of 3 tenths and 8 hundredths.
Answer:
A.
Step-by-step explanation: By looking at the image it shows 2 not 4.
The only option that explains the mistake Jill made in the model is;
Option A; Jill used 3 groups of 3 tenths and 2 hundredths rather than 4 groups.
The model Jill made is to show the quotient of 1.28 ÷ 4.
Now, this means she wants to divide 1.28 into 4 equal parts. Thus, the model must show 4 identical quotients.
The image of the model we are seeing from Jill is showing;
3 groups of 3 tenths and 2 hundredths.
Since it is showing 3 groups instead of 4 groups, the it is clear that Jill made a mistake in her model.
In conclusion, the only option that identifies the mistake correctly is option A.
