I believe the correct awnser is c let me know !
Answer:
x = -1, x = 1
Step-by-step explanation:
Factor the equation. (It's a difference of squares, so we know the form will be (a-b)(a+b).)
Test this by FOILing it out, if you're unsure. This is something it can be good to memorize!
Set it equal to 0.
Separate the two parenthetical expressions by the Zero Product Property.
Solve for x!
Answer:
It is an acute triangle because all the angles are less than 90 degrees.
Well here's your answer straight <u><em>he must pay 29.82$ </em></u>and here's my work,
- 20% of 35 is 7 and since its 20% off we must subtract 35-7=28
- Next it said there's a 6.5 tax so that means we are adding on to 28$
- 6.5 of 28 is 1.82 so we add 28+1.82 which equals your answer 29.82
<span>Plan 1: $50 for a monthly pass and a $3 fee for each gym visit
So, the monthly pass is 50 plus 3 for each visit. You know 50 stays constant no matter how much Hayley goes to the gym so you can already put that into the form as 'b' also known as the y-intercept.
y=mx+50
Now, you need to find the slope which is the amount it increases or decreases by every time. Since Hayley gets charged $3 every visit, that would be the slope (m).
Plan 1: y=3x+50

Plan 2: $10 for each gym visit
</span>
There is only a slope (m) for this. Technically there is a y-intercept (b), but since that is 0 it is not needed. Plug in the values.
y=mx+b
y=10x
