Answer:
i think its x = -14/19 Not 100% sure
Answer:
44 feet
Step-by-step explanation:
P = 10 + 12 + 10 + 12
P = 10(2) + 12(2)
P = 20 + 24
P = 44
The slope-intercept form:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
m - slope
b - y-intercept
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
substitute the coordinates of the points (8, 0) and (20, 12) to the formula:
![m=\dfrac{12-0}{20-8}=\dfrac{12}{12}=1](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B12-0%7D%7B20-8%7D%3D%5Cdfrac%7B12%7D%7B12%7D%3D1)
y = 1x + b = x + b
Put the coordinates of the point (8, 0) to the equation of a line:
0 = 8 + b <em>subtract 8 from both sides</em>
-8 = b
<h3>Answer: y = x - 8</h3>
The mistake she had done is she should have reversed the inequality as per the division property of inequality.
<h3>What is inequality?</h3>
A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
The inequality is:
500 − 30x ≥ 200 −500 −500 −30x ≥ −300 x ≥ 10
Given:
Jamie had $500 in her savings account.
She wants to have at least $200 left in the account at the end of the school year.
The inequality she had done is
500 − 30x ≥ 200 −500 −500 −30x ≥ −300 x ≥ 10
But when she was dividing she should have reversed the inequality as per the division property of inequality.
