Answer:
51.5 in , Formula: y=1/2x+48
Step-by-step explanation:
First, create a formula as shown above
Next, plug your number into the formula:
y=1/2(7)+48
Then, simplify your equation by multiplying 1/2 by 7 and getting 3.5, now add 48 and you get 51.5in
Last, check your work by adding 1/2 seven times and you will get the same result
I hope this helps you and if it does please give a thanks (i would eternally appreciate a brainliest trying t level up)

Answer:
D.−√5
Step-by-step explanation:
4 sqrt(20) -3 sqrt(45)
We know that sqrt(ab) = sqrt(a) sqrt(b)
4 sqrt(4) sqrt(5) - 3 sqrt(9) sqrt(5)
4 *2 sqrt(5) - 3 *3 sqrt(5)
8 sqrt(5) - 9 sqrt(5)
- sqrt(5)
Answer:
2
Use the prime factorization:
7 * 5 * 1 = 35
7 * 5 * 2 = 70
Answer:
It was difficult reading the question, as written. Check my assumptions.
Step-by-step explanation:
"five more than the product of two and a number,
decreased by seven"
---
Let the "number" be a.
We are told "five more than . ." means +5,
"the product of two and a number" means 2a,
"decreased by seven" mean -7
Put the statements together to obtain:
+5+2a-7
Simplify to 2a-2
Evaluate when a = 8:
2a-2
2(8)-2
16-2
= 14
1. m
2. One set of ordered pairs
3. b
To show why this is, I’m going to explain how to write the equation for a linear function with two random sets of ordered pairs - (1,0) and (5, 8).
First, find the slope. The formula for slope is m = (y2 - y1)/(x2-x1) where m is the slope and (x1, y1) and (x2, y2) are two sets of points.
This is why #1 is m. M is the letter used when finding slope.
To find m, I plug in the two sets of ordered pairs.
m = (8-0)/(5-1)
m = 8/4
m = 2
An equation for a line (linear function) is written in something called slope-intercept form. It looks like y = mx + b. m is the slope and b is the y-intercept (number y equals when x = 0). If m = 3 and b = 1, the equation would be y = 3x + 1.
Here, you have just solved for m and know it equals 2. Plug that value in for m.
y = 2x + b
To solve for b, plug one ordered pair in for x and y. I will use (1,0)
0 = 2(1) + b
0 = 2 + b
-2 = b
Now that you know b = -2, plug that in for b.
y = 2x - 2. Now you have the equation fo the line.
