Put this equation into slope- intercept form. -2x + 3y = 9
Answers
Answer:
y = 2/3x + 3
Step-by-step explanation:
In order to put it in slope intercept form (y = mx + b), y needs to be isolated.
Add 2x to both sides:
-2x + 3y = 9
3y = 2x + 9
Then, divide both sides of the equation by 3.
3y = 2x + 9
y = 2/3x + 3 is the equation in slope intercept form
Answer:
Slope-intercept form:
→ y = (2/3)x + 3
Step-by-step explanation:
Given equation,
→ -2x + 3y = 9
Now we have to,
→ Convert this given equation into the slope-intercept form.
The slope-intercept form is,
→ y = mx + b
Let's convert the equation,
→ -2x + 3y = 9
→ 3y = 9 + 2x
→ 3y = 2x + 9
→ y = (2x + 9)/3
→ y = (2x/3) + (9/3)
→ y = (2/3)x + 3
From this slope-intercept form:
→ Slope (m) = 2/3
→ y-intercept (b) = 3
Thus, the answer is y = (2/3)x + 3.

Jefferson Middle School needs to see a 300% gain in PTO fundraiser
sales from last year. If they sold a total of $2,420 last year, how much do
they need to sell this year to meet their goal? *
Answers
Given parameters:
Percentage gain = 300%
Selling cost last year = $2420
Unknown:
Selling cost this year = ?
Solution:
To solve this problem;
Profit percent = [tex]\frac{Selling cost this year - Selling cost last year}{Selling cost last year} x 100[/tex]
300 = [tex]\frac{S - 2420}{2420} x 100[/tex]
3 = [tex]\frac{S - 2420}{2420}[/tex]
S- 2420 = 7260
S = $9680
To make a 300% gain, Jefferson Middle school needs a $9680 from fundraiser sales this year.

Answers
Answer: 20% of 95
Step-by-step explanation: 20% of 95 is 19 and 90% of 20 is 18. So 19>18.
Hi! I believe your answer is ---20% of 95--- because 90% of 20 is 18, but 20% of 95 is 19, so that is larger. I hope this helps you! Good luck and have a great day. :)
