Solve for x, give exact answers: 6x^2 - 7x - 3 = 0
Novosadov [1.4K]

Answer:

Step-by-step explanation:

6x∧2-7x-3=0

the coefficient of x² multiplied by -3 = -18

we need to look for 2 numbers that when we add it to together it will equate to -7x

+2 and -9 is the answer

6x∧2+2x-9x-3=0

2x(3x+1)-3(3x+1)=0

(2x-3)(3x+1)=0

equate each brackets to 0

2x-3=0   3x+1=0

2x=3        3x=-1

x=3/2         x=-1/3

Luda [366]

Answer:

The midpoint of MN is <u>(7,1)</u>

Add the x coordinates 7+7=14 then you divide that by 2 giving you 7.

Then you add the y coordinates together 6+(-4)=2 then divide by 2 and that gives you 1. Therefore the answer is (7,1)

Help!!!! giving brainiest!!!
Margarita [4]
Hi there!

In order to find x, we'll need to create an expression. We know that angle x would be 180 - angle ABC - y. Since we know that angle ABC is equal to 30, we can substitute that in. This gives us 180 - 30 - y. Lastly, we can simplify to get our expression. The expression is 150 - y. The answer is the first option.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
