Answer:
<em>The temperature in Miami is 9/5 times the temperature in San Diego.</em>
Step-by-step explanation:
<u>Ratios</u>
To compare the temperature in Miami (45) with the temperature in San Diego (25), we use the division or ratio between both numbers:
Simplify the fraction dividing by 5:
Since the relation between them is 9/5, it means the temperature in Miami is 9/5 times the temperature in San Diego.
Three possible answers are:
y = 2x-1
y = 5x-1
y = -3x-1
All of them have the same y intercept of -1. The slopes are the only thing that differ.
Any linear equation can be written in the form y = mx+b where
m = slope
b = y intercept
Answer : x=3
Step-by-step explanation:
Explanation:
2x+3=9
We want to find the variable x, so we have to make it alone. To do so, first subtract 3 from both sides of the equation:
2x+3 − 3=9 − 3
2x=6
Now divide both sides by 2:
2x2=62
So the final answer is:
x=3
<h3>
Answer: 49</h3>
Work Shown:
Replace x with 3, replace y with -8. Use order of operations PEMDAS to simplify.
x^2 + y^2 + x*y
3^2 + (-8)^2 + 3*(-8)
9 + 64 - 24
73 - 24
49
