oee [108]3 years ago
4 0

Answer:

False

Step-by-step explanation:

y = 2x + 1

Substitute the point (4,3) into the equation and see if it is true

3 = 2(4) +1

3 =8+1

3 =9

This is false, so the point is not a solution

What you do is you combine like terms... so in your instance it is using m.

-3m      -3m
3m + 2 =-10
        +10 +10
3m= 12
m= 4

Find x<br><br> 5x-7+8x-55<br><br> 13 POINTS <br><br> Show work please
Law Incorporation [45]

Combine like terms. The 5x is grouped to the 8x and the -7 isgrouped with the -55.

This means 5x + 8x = 13x and -7 - 55 = -62

The new expression is 13x - 62. We can't find the exact value of x because the expression wasn't set equal to anything.

Use factoring to solve the quadratic equation x2 − 2x − 3 = 12.
melomori [17]

Answer:

x_1=5\\x_2=-3

Step-by-step explanation:

You have the following quadratic equation given in the problem:

x^{2}-2x-3=12

You must make the equation equal to zero, as following:

x^{2}-2x-3-12=0

Add like terms:

 x^{2}-2x-15=0

Now, to factor the equation, you must find two numbers whose sum is -2 and whose product is -15. Therefore, you have:

(x-5)(x+3)=0\\x_1=5\\x_2=-3
