What is x² + 7x - 30​

Mathematics
1 answer:
Aleonysh [2.5K]3 years ago
6 0

Are you looking for the value of x?

We can complete the square/factor:

x^2+7x-30=0

(x+10)(x-3)=0

By the zero product property rule, we have two equations, x+10=0 and x-3=0.

So the zeroes of x are -10 and 3

Hope this helped. Comment below if this didn't make sense.

If y = 3x+b intersects y= mx +3 at (2, 3), find the value of b and m.
Darina [25.2K]

Answer:

The value of b is -3 and m is 0.

Step-by-step explanation:

You have to substitute the coordinates into both equation in order to find m and b value :

Find m,

y = mx + 3

At (2,3),

3 = m(2) + 3

3 - 3 = 2m

2m = 0

m = 0

Find b,

y = 3x + b

At (2,3),

3 = 3(2) + b

b + 6 = 3

b = 3 - 6

b =  - 3
