Answer:

$beinggreat78 ~is ~here ~to~ help~ you!$

Let's start with 5 squared. 5 squared, or just squared in general, represents the number behind it times itself.

$5^2~or~ 5*5 = 25$

Now, add 3

$25 + 3 = 28$

Next, subtract 1

$28 - 1 = 27$

Now, you must divide, because the line under the first equation represents division, or a fraction. For this case, division. Before dividing your result, 27, by y, the second equation, you first want to solve equation 2, y.

$\frac{18}{2} = 9$

Lastly, divide x by y, 27 divided by 9

$\frac{27}{9} = 3$

The problem is solved! The final answer is 3

Let's solve your equation step-by-step.

Question 1: −2(6−2x) =4(−3+x)

Step 1: Simplify both sides of the equation.

−2(6−2x) =4(−3+x)

(−2) (6) +(−2) (−2x) =(4)(−3)+(4)(x)(Distribute)

−12+4x=−12+4x

4x−12=4x−12

Step 2: Subtract 4x from both sides.

4x−12−4x=4x−12−4x

−12=−12

Step 3: Add 12 to both sides.

−12+12=−12+12

0=0

Answer: All real numbers are solutions.

Question 2:

Let's solve your equation step-by-step.

5−1(2x+3) =−2(4+x)

Step 1: Simplify both sides of the equation.

5−1(2x+3) =−2(4+x)

5+(−1) (2x) +(−1) (3) =(−2) (4)+(−2)(x)(Distribute)

5+−2x+−3=−8+−2x

(−2x) +(5+−3) =−2x−8(Combine Like Terms)

−2x+2=−2x−8

Step 2: Add 2x to both sides.

−2x+2+2x=−2x−8+2x

2=−8

Step 3: Subtract 2 from both sides.

2−2=−8−2

0=−10

Answer: There are no solutions.

Bas_tet [7]

Answer:

It should be reported as 20.648%

Step-by-step explanation:

Since we have 2 different observed values hence we shall use an average of the 2 values to report the result

Thus value is $\frac{19.564+21.731}{2}=20.6475%$

As we can see that the least count of our observations is upto 3 decimal places hence we have to report a result upto only 3 decimal places thus we need to round off the fourth decimal place thus the digit shall be increased by 1 since we have to drop off 5 and the digit before 5 is 7 which is an odd number.

Thus the result shall be 20.648%

Someone please help with this question :)!

Elodia [21]

I think a) would be the answer. I proceeded by elimination: the domaine of the function goes from 3 and continues to infinity, so that leaves with a) and b) as possible answers. Both have the same range and both of their functions reflect over the x axis, so we have to compare the two answer by looking at the position of the function in the graph. The function is in the first quadrant (top right corner), so the position of the function has to be at our right, which leads us to a).
