Answer:
y = 2x + 3
General Formulas and Concepts:
<u>Algebra I</u>
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
Slope <em>m</em> = 2
y-intercept <em>b</em> = 3
<u>Step 2: Write function</u>
y = 2x + 3
I would word it ...
"nine times the sum of x and the square of y is eighteen".
As a math sentence, it looks like
... 9(y^2 +x) = 18
or
... 9(y² +x) = 18
Answer:
$24/5 weeks = $4.80 saved per week.
$4.80 is 30% of what number?.....
4.8=0.3*X....... 4.8/0.3=X ........X=16
So, Joseph receives $16 per week.
Step-by-step explanation:
So, you know that x=-7 and y=3, and you have the expression x - y^3, and when the question says "evaluate"(in this context) it means simplify into the smallest amount of terms possible. So you substitute what x is equal to into the expression and the same for y. so you get (-7) - (3)^3. Then you use pemdas to simplify.
