Answer:
Step-by-step explanation:
y=mx+b b= y-intercept y-intercept=where the line crosses the y-axis m=slope slope== rise/run or slope formula, m=y2-y1/x2-x1
For example, number 1's slope is 5/3. On a graph, you would go up 5 (not in block, but in numerical value) and right 3. The y-intercept is -2. This is where your line starts on the graph.
sorry, cant help ya there buddy
The lengths of x and y are shown in the figure below.
Which number line shows the closest approximate values of x and y?
Answer:
x = 6.40312423743 y=12.8062484748
Step-by-step explanation:
To find the value of x, you must use the Pythagorean Therom.
a^2+b^2=c^2
5^2+4^2=c^2
25+16=c^2
41=c^2
Then find the square root of 41 so x = 6.40312423743.
Then to find y you must substitute the value of x in and use the triangle formula: 1/2(b)(h).
1/2(4)(6.40312423743)
y=12.8062484748
The answer is x = 6.40312423743 y=12.8062484748

Solve for m.
m – 7/8 = 5
Write your answer as a fraction or as a whole or mixed number.
m = ____
Answer:
5 7/8
Step-by-step explanation:
Do the inverse operation.
5 + 7/8 = 5 7/8
Or, do this instead!
Add 7/8 to both sides of the equation. On the side before the equal sign, -78 and +78 cancel out, leaving m all by itself. Bring down the equals sign and we have m = 5 7/8!
Jacki evaluated the expression below.
2 cubed (3 minus 1) + 4 (8 minus 12) = 2 cubed (2) + 4 (4) = 8 (2) + 16 = 16 + 16 = 32.
What was Jacki’s error?
Jacki should have simplified the exponent first.
Jacki should have multiplied 4 and 8 first.
Jacki did not subtract 12 from 8 correctly.
Jacki should not have multiplied 8 and 2
Answer: Jacki did not subtract 12 from 8 correctly
Step-by-step explanation: it should be -4
Answer: C
Step-by-step explanation:
Jacki didn’t subtract 12 from 8 correctly he was suppose to get a negative and not 12

There are 31 girls and 25 boys in the marching band. When the band marches, they are in 7 rows. How many people are in each row?
Answer:
there are 8 people in each row
Step-by-step explanation:
(31+25) ÷ 7
Answer:
8 people
Step-by-step explanation:
Since there are 31 girls and 25 boys, you can add them to get 56 people total.When they march, there are 7 rows. So, you can divide 56 by 7, and get 8.Therefore, you have 8 people in each row.An employee earns a 25% commission rate on his sales. One day, he earned $175. What was his amount of sales?
Help Please
Answer:
$700
Step-by-step explanation:
25% = 1/4
the sales would be 100% or 4/4
So if commission rate is 1/4, to find the sales we multiply this by 4:
$175*4= $700
The sales would amount to $700

How many 2 digit prime numbers can you make make with 2,3,7,9 without repeating a digit?
So you can make 6 prime numbers.
Answer:
6
Hope you could get an idea from here.
Doubt clarification - use comment section.
Answer:
Hey mate!
Step-by-step explanation:
Lets take two places _ _
Now first position is filled in 4 ways (can use 2 3 7 9) that implies 4C1
then second position is filled in 3 ways since for first position we used a digit
and the condition is that not to repeat the digits, so it is done in 3C1 ways.
so the answer is 4*3 or (4C1*3C1)=12;

p/ 1 6/7=−4.4 help please!!!!!!!
Answer:
Sorry, I can't type well.
The solution of the equation p / [1 ⁶/₇] = - 4.4 will be negative 8.17.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The equation is given below.
p / [1 ⁶/₇] = - 4.4
Convert the mixed fraction number into a decimal number. Then we have
1 ⁶/₇ = 1 + ⁶/₇
1 ⁶/₇ = 1 + 0.857
1 ⁶/₇ = 1.857
Then the equation is rewritten as,
p / 1.857 = - 4.4
Simplify the equation, then we have
p = - 4.4 x 1.857
p = - 8.17
The solution of the equation p / [1 ⁶/₇] = - 4.4 will be negative 8.17.
