Step-by-step explanation:
8.9 - 1.4x + (-6.5) +3.4
12.3 - 1.4x - 6.5=
12.3 - 7.9x
Answer:
Step-by-step explanation:
<u>Put input value instead of the x into equation and calculate the output:</u>
<u>x = -4, then find the value of y:</u>
- y = -5(-4) - 7 = 20 - 7 = 13
The output is 13 when the input is -4
Answer:
92%
Step-by-step explanation:
This is because all you have to do to turn a decimal into percentage is to move the decimal over 2 spots, and drop the Zero.
The consecutive positive integers would be: x and (x+1),
We would have to solve the following equation to find these numbers:
x(x+1)-[x+(x+1)]=29
x²+x-2x-1=29
x²-x-30=0
x=[1⁺₋√(1+120)]/2
x=(1⁺₋11)/2
We have two possible solutions:
x₁=(1-11)/2=-5 then: (x+1)=-5+1=-4 This is not the solution.
x₂=(1+11)/2=6 then: (x+1)=6+1=7 This solution is right.
Answer: the numbers would be 6 and 7.
