a(x+1)(x-1)+b(x-2)(x+1)+(x+1)^2=9x^2-x-10
(x+1)(a(x-1)+b(x-2)+(x+1))=(x+1)(9x-10)
a(x-1)+b(x-2)+x+1=9x-10
Now this equation is much simpler!
(a+b)x-a-2b+x+1=9x-10
(a+b)x-a-2b=8x-11
(a+b-8)x-a-2b-11=0
a+b-8=(a+2b-11)/x
I can't solve it 3 variables and 1 equations means infinite answers so yea.

John needs a computer for his summer class. The computer costs 385 but since he is still in school, he gets a 30% discount. What is the total amount he will spend on his computer?
Answer:
269.50, you could search it up
The total amount that he will spend on his computer will be $269.5.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
For his summer course, John has to have a computer. Since he is still enrolled in school, he receives a 30% discount off the computer's $385 price.
The amount of discount is calculated as,
⇒ 0.30 x 385
⇒ 115.5
Then the amount spent on the computer is calculated as,
⇒ 385 - 115.5
⇒ 269.5
The total amount that he will spend on his computer will be $269.5.

2t ² + 5t - 63 Factor the trinomial
Answer:
(2t-9)(t+7)
Step-by-step explanation:
2t^2 + 5t - 63
9x14 = 63
14 - 9 = 5
2t^2+14t - 9t -63
2t ( t+7) -9 (t+7)
(2t-9)(t+7)
Hope this helps!! :))
Step-by-step explanation:
2 t ² + 5t - 63 = 0
2 t² + 14 t. - 9 t -63 = 0
2t ( t + 7) - 9 ( t + 7) = 0
(2t - 9) ( t + 7 ) = 0
t = - 7 , 9 / 2

What is the sum of the greatest and least numbers below:
Answer:
1/6
Step-by-step explanation:
Step 1: Make remaining mixed numbers improper fractions:
8 1/5 = ((8*5)+1)/5 = 41/5
-8 2/5 = -((8*5)+2)/5 = -42/5
Step 2: Order fractions from least to greatest:
-26/3 <- Least
-42/5
-54/7
41/5
53/6 <- Greatest
Step 3: Find the sum of the least and greatest fractions:
Given: -26/3+53/6
Make equivalent fractions: -52/6+53/6
Rearrange: 53/6-52/6
Evaluate: (53-52)/6 = 1/6
Therefore, the sum of the greatest and least numbers is 1/6

Find the slope of the line passing through the points and ( -6, -5 ) and (4, 4)
Answer:
Slope: 9/10
Step-by-step explanation:
We need to find the slope of the line that passes through the coordinates given.
To find the slope, we would use the slope formula: m = y2-y1/x2-x1
Plug in your coordinates and solve:
m = 4-(-5)/4-(-6)
m = 4+5/4+6
m = 9/10
Since we can't simplify further, the slope of the line would be 9/10.

Area of first ∆ :-
A = 1/2 * b * h
A = 1/2 * 14.5 cm * 6cm
A = 3 × 14.5 cm²
A = 43.5 cm²
Area of second ∆ :-
A = 1/2 * ( sum of || sides) * h
A = 1/2 * ( 9 cm + 19cm) * 8cm
A = 4cm * 28cm
A = 112 cm²

Answer:

Step-by-step explanation:
You already have 700 words typed out, which means you have 5500-700 = 4800 words left to type. If you are typing at a rate of 20 words per minute, you will need 4800/20 = 240 more minutes to finish typing your essay. That is 240/60 hours, or 4 hours.
