X^2 + 3x - 10 = 0

2x + 3x - 10 = 0

2x + 3x = 5x

5x -10 = 0

+10 +10

5x = 10

5x/5 = 10/5

X = 2


Checking: 2^2 + 3(2) - 10 = 0

4 + 3(2) - 10 = 0

4 + 6 - 10 = 0

10 - 10 = 0

0 = 0

For which independent value do the equations generate the same dependent value? y1=6x-16 , y2=3x-10
Nikitich [7]
The question asks which x-value gives the same y-value for both equations, so if you need the ys to be equal, you can set both equations equal to each other, giving you 6x-16=3x-10. Now, solve for x. 6x-16=3x-10, subtract 3x and add 16, 3x=6, divide 3, x=2. Your answer is x=2.

The correct expression for a number which is 9 times as big as the number obtained after p has been increased
defon

Answer:

9(p + 4)

Step-by-step explanation:

One of the unknown variable is p.

First of all, we know that the number is 9 times as big (multiplication) as the new number obtained through the addition of four to p i.e (p + 4).

Translating the word problem into an algebraic expression, we have;

9 * (p + 4) = 9(p + 4)

Simplifying further, we have;

9p + 36
