Answer:
y = -2/7x - 22/7
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
Slope Formula: ![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
<u>Step 1: Define</u>
Point (-4, -2)
Point (3, -4)
<u>Step 2: Find slope </u><em><u>m</u></em>
- Substitute:
![m=\frac{-4+2}{3+4}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-4%2B2%7D%7B3%2B4%7D)
- Add:
![m=\frac{-2}{7}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-2%7D%7B7%7D)
<u>Step 3: Find y-intercept </u><em><u>b</u></em>
- Define: y = -2/7x + b
- Substitute: -4 = -2/7(3) + b
- Multiply: -4 = -6/7 + b
- Isolate <em>b</em>: -22/7 = b
- Rewrite: b = -22/7
<u>Step 4: Write linear equation</u>
y = -2/7x - 22/7
Answer:
Bryson’s age is 14 years
Step-by-step explanation:
Let
x ----> Bryson’s age
we know that
Bryson’s age multiplied by 3 minus 4 must be equal to 38
so
The linear equation that represent this situation is
![3x-4=38](https://tex.z-dn.net/?f=3x-4%3D38)
solve for x
Adds 4 both sides
![3x=38+4](https://tex.z-dn.net/?f=3x%3D38%2B4)
![3x=42](https://tex.z-dn.net/?f=3x%3D42)
Divide by 3 both sides
![x=14](https://tex.z-dn.net/?f=x%3D14)
therefore
Bryson’s age is 14 years
4/5 = 80%
2/3 = 66.66666...%
4/5 is a bigger fraction, so (4/5) x 45 is a bigger fraction.

Answer:
B.) 6
2.) 70
3.) 56
Step-by-step explanation:
B.) 2(6) - 6
= 12 - 6
=6
2.) 7(2(3)+4)
=7(6+4)
=42+28
=70
3.) 10(3) + 4(3) + 14
= 30 + 12 + 14
= 42+14
=56
Have a wonderful day
