Answer:
-1.1, 6.1
Step-by-step explanation:
-2X^2+10X+14=0
(-2X^2+10X+14)/-2=0
X^2-5X-7=0
Then use the quadratic formula because you can't factor
Fill in the equations and solve. One should have the plus and the other should have the minus and that's how you get the 2 different answers.
A=1
B=-5
C=-7
Answer:
B. 11 2/3
Step-by-step explanation:
c = 5 5/6*2
Change the mixed number to an improper fraction
5 5/6 = (6*5+5)/6 = (30+5)/6 = 35/6
c = 35/6 *2
c = 35/6 *2/1
= 70/6
Now we change it back to a mixed number
6 goes into 70 11 times
11*6 = 66 with 4 left over
11 4/6
We can simplify 4/6 by dividing the top and bottom by 2
11 2/3
Answer: 7
Step-by-step explanation:
1. multiply both sides by -6 so the -6 on the right side could cancel out and the left side would be -6: 1= a-13/-6 ==> -6=a-13
2. add both sides by 13 so -13 on the right side could cancel out and the left side would be -6+13: -6=a-13 ==> -6+13=a-13+13
3. you know -6+13 equals 7 right? so the answer is a=7
Answer:
−x+−7
Step-by-step explanation:
Let's simplify step-by-step.
4x−6−(5x+1)
Distribute the Negative Sign:
=4x−6+−1(5x+1)
=4x+−6+−1(5x)+(−1)(1)
=4x+−6+−5x+−1
Combine Like Terms:
=4x+−6+−5x+−1
=(4x+−5x)+(−6+−1)
=−x+−7
