X^2 + 9x -10 = (x -1)(x +10) = (x +(-1)) (x + 10)

Answer with explanation:

\rightarrow x^2+9 x-10\\\\=x^2+10 x-x-10\\\\= x\times (x+10)-1 \times (x+10)\\\\=(x-1)(x+10)

From the table

Sum of term which contains coefficient of , x =9=-1+10

Constant term = -10= -1 × 10

⇒ (x+p)(x+q)=(x-1)(x+10)

Comparing , L HS and R HS

p= -1

q= 10

Option A:→ -1 and 10

1) check if they given ordered pairs are solutions to the equation or not.
ziro4ka [17]
Answer: a) Yes
b) No


Explanation: Substitute the values of X and Y from the given points into the equation. I’ll use a) as an example:
Given point: (1,-3)
Equation: 4x-2y=10
Value of X: 1
Value of Y: -3
Substitute X and Y: 4(1)-2(-3)=10
4-(-6)=10
4+6=10 ✔︎

Therefore, the given ordered pair is a proper solution to the equation 4x-2y=10.

*You can use the same method for question b).*

The difference between the acute angles of a right angled triangle is 72degree find them .
MaRussiya [10]

The 2 angles add up to 90 degrees so

x + y = 90, also:-

x - y = 72 (given)

adding the 2 equations:-

2x = 162

x = 81

and therefore

y + 81 = 90

y = 9


Answer the 2 angles are 81 and 9 degrees

lorasvet [3.4K]

Answer:

The speed of the boat is 20 km/hr

Step-by-step explanation:

Let s be the speed of boat in still water

Let d be the distance

Upstream speed = s-4

Jane took 30 min to drive her boat upstream to water-ski at her favorite spot.

So, Distance traveled in upstream =Speed \times time =(s-4) \times \frac{30}{60}

Downstream speed = s+4

So, Distance traveled in downstream = Speed \times time =(s+4) \times \frac{20}{60}

So, (s-4) \times \frac{30}{60}=(s+4) \times \frac{20}{60}

30s-120=20s+80

10s=200

s=20

Hence The speed of the boat is 20 km/hr
