Answer:
y = 3n - 2
Step-by-step explanation:
so to find the slope or rate of change we use the equation
y 2 - y1 / x2 - x1
soo lets use the points
(1, 1) and (2, 4)
4 - 1/ 2 - 1
3/1
3
y = 3n + b
now we substitute a point we did not use yet
(3, 7)
7 = 3(3) + b
7 = 9 + b
b = -2
y = 3n - 2
now check
(4,10)
10 = 3(4) - 2 ?
10 = 12 - 2 ?
10 = 10
Answer:
y = 3n - 2
Step-by-step explanation:
y = mx + b or y = nx + b
Where m or n represents the slope
[tex]m\ or\ n=\frac{y_2-y_1}{x_2-x_1} \\\\m\ or\ n=\frac{4-1}{2-1} \\\\m\ or\ n=\frac{3}{1} \\\\m\ or\ n=3[/tex]
y = 3n + b
(n, y) ==> (2, 4)
y = 3n + b
4 = 3(2) + b
4 = 6 + b
-6 -6
-2 = b
y = 3n - 2
Check your answer using (2, 4):
y = 3n - 2
4 = 3(2) - 2
4 = 6 -2
4 =4
This statement is correct
Hope this helps!

Answer:
16
Step-by-step explanation:
Line 1: ◄ + ◄ + ◄ = 30
3◄ = 30
◄ = 10
The triangle equals 10.
Line 2: ◄ + ◘ + ◘ = 18
10 + 2◘ = 18
2◘ = 8
◘ = 4
The square equals 4.
Line 3: ◘ - ○ = 2
4 - ○ = 2
-○ = -2
○ = 2
The circle equals 2.
○ + ◄ + ◘ = 2 + 10 + 4 = 16

Step-by-step explanation:
Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah a total of 8 people took the trip. She was able to purchase coach tickets for $200 and first class tickets for $1210. She used her total budget for airfare for the trip, which was $4630. How many first class tickets did she buy? How many coach tickets did she buy?
Answer:
3 1st class tickets
5 coach tickets
Step-by-step explanation:
Quantity:: C + F = 8
Value:: 380C + 1180F = 5440
Modify;:
1180C + 1180F = 1180*8
380C + 1180F = 5440
Subtract and solve for "C"::
800C = 4000
C = 5 (# of coach tickets)
Let x = number of 1st class tickets
8-x = number of coach tickets
and
She bought 3 1st class tickets
She bought 5 coach tickets
What is 10 of the power mean?
Answer:
A power of 10 is as many number 10s as indicated by the exponent multiplied together.
Step-by-step explanation:
Thus, shown in long-form, a power of 10 is the number 1 followed by n zeros, where n is the exponent and is greater than 0; for example, 106 is written 1,000,000.
Answer:10 of the power means you add on the zeros
Step-by-step explanation:
say if your question says 10 to the 4 power it would be 10,000 because the power stands for the zeros in your answer.

Step-by-step explanation:
Start with the rectangle of 8×6 which is 48.
Then start with a base, 2×6=12 and add 4, 2 per triangle. One base equals 16 and because it's 2 bases multiply by 2 equals 32.

Three-Dimensional Figures and Spacial Reasoning (PLEASE HELP)
Answer:
could you word this in a diffrent way me english is not so good
Step-by-step explanation:
Find the area, please show your work
Answer:
25
Step-by-step explanation:
8 x 4 / 2 gets you the area of the big triangle, which is 32 / 2 = 16
1 x 8 for the rectangle, so far you're at 16 + 8 = 24
The tiny triangles are half the squares so add them together ( 1/2 + 1/2) to get 2/2 = 1/1
add them together to get 24 + 1 = 25
You can also do it as if you take the big triangles and add them together to get a square, you get a 4 x 4 square
Then you have the 1 x 8 rectangle
do the same thing with the tiny triangles as the big triangles, and you get 1
(4 x 4) + (1 x 8) + 1
16 + 8 + 1
24 + 1 = 25

A line passes through the points (2, -4) and (4, 2). What is the equation of this line in slope-intercept form?
A. y = 3x – 10
B. y = 2x – 14
C. y = 3x + 14
D. y = x + 4
Answer:
C. y = 3x + 14
Hope it helps!!!Brainliest pls!!!Answer:
A. y = 3x – 10
Step-by-step explanation:
We have equation of line passing through two points (x1, y1) and (x2, y2) as,
(y - y1) = [(y2 - y1)/(x2 - x1)] (x - x1)
(y + 4) = [(2 + 4)/(4 - 2)] (x - 2)
(y + 4) = (6/2)(x - 2)
(y + 4) = 3(x - 2)
3x - y - 10 = 0 --- (1)
Now, slope-intercept form of line is y = mx + c
Rearranging equation (1) ⇒ y = 3x - 10
Therefore, the required equation is y = 3x - 10

What is the value of 1 over 2 x^3 + 3.4y when x = 3 and y = 4?
A. 15.85
B. 18.1
C. 27.1
D. 31.6
Answer:
67.6
Solving Steps:
=> 2x³ + 3.4y
=> 2(3)³ + 3.4(4)
=> 2(27) + 13.6
=> 54 + 13.6
=> 67.6
Hey there!
1/2x^3 + 3.4y
= 1/2(3)^3 + 3.4(4)
= 1/2(3 * 3 * 3) + 3.4(4)
= 1/2(9*3) + 3.4(4)
= 1/2(27) + 3.4(4)
= 27/2 + 3.4(4)
= 13.5 + 13.6
= 27.1
Therefore, your answer is: 27.1

4 1/5 + 2 5/6=
A. 6 1/30
B. 6 1/6
C. 7 1/4
D. 7 1/30
PLEASE HELP
Answer:
the answer is D. 7 1/30
Step-by-step explanation:
first make them into improper fractions:
21/5 and 17/6
second find a common denominater (im using 30) and multiply so they have 30 as the denominater:
126/30 and 85/30
third add the improper fractions:
126/30 + 85/30 = 211/30 and as a mixed number it would be 7 1/30
Answer:
D. 7 1/30
Step-by-step explanation:
4 1/5 + 2 5/6=
The first thing we notice here are the fractions, whenever working with fractions, the first thing to do to make your life easier is to find the common denominator for the fractions. What's a common denominator?? a common denominator is when two fractions can have the same number on the bottom. We know that 5 times 6 gives you 30, so 30 can be our common denominator.
4 1/30 + 2 5/30 =
ok so, we changed our denominator, but now what? since we changed the denominator, this also affects the numerator (the numbers on the top). to fix this, we have to do the same to the numerator as we did to the denominator. to change 5 into 30, we multiplied it by 6, this means we also have to multiply 1 by six, 6/30. Don't forget the other fraction too! Since we multiplied 6 by 5 to get 30, we also have to multiply 5 by 5, 25/30.
4 6/30 + 2 25/30 =
now that the fractions have the same denominator, we can just go ahead and add the digits and numerators!
we know that 4 + 2 = 6, so we can remove them and put 6 at the end of the equation
6/30 + 25/30 = 6
but we aren't done yet, now we add 6 + 25 which gives us 31, out of 30
wait! 31/30? that doesn't sound right. 30 out of 30 automatically gives us a 1, so we can add that to the 6 we got earlier, 6 + 1 = 7. Since we are left with 1/30 we will add this to the final answer: 4 6/30 + 2 25/30 = 7 1/30

A shoe store marks up its merchandise by 8%. What was the selling price of a pair of shoes whose wholesale price is $24.50? Show work
Answer:
Result: $26.46
Steps:
$24.50 (increase) + 8% = $26.46
24.50 x (1 + 8%) = 24.50 x (1 + 0.08) = 26.46
I'm truly sorry if my math is incorrect.

Answer:
$26.46
Step-by-step explanation:
1 example $24.50*(108%)

A watering can contained 5 1/2 quarts water. After all the plants were watered, only 4 cups remained.
How many cups of water were used to water the plants?
7 cups
18 cups
40 cups
84 cups
Answer:
18 cups
Step-by-step explanation:
Because there is 4 cups in a quart, we can turn 5 1/2 or 5.5 quarts into 22 cups:
5 1/2 or 5.5
( 5 x 4) + (0.5 x 4) = 22
Since we need to find how many cups were used, that is x. Because 22 cups is the total amount of cups and 4 is the amount remaining then the equation would look like this:
x + 4 = 22
Finally you solve to get:
x = 18 cups
