I just need questions so try your best hope this works
The denominator is equal to the numerator.
<u>Step-by-step explanation</u>:
- For a fraction to be equal to 1, the value of denominator and the value of numerator should be same.
- For instance, the fraction 2/2 = 1 because the number in the denominator is 2 and the numerator is also 2.
- Both cancel out each other that is equal to 1.
U have to solve it then right the equation down
Answer:
Step-by-step explanation:
Let the width of the pool deck be x.
- Dimensions of the pool are 12 + 2x and 24 + 2x.
- Total area is 1408 ft².
<u>We have equation:</u>
- (12 + 2x)(24 + 2x) = 1408
- 12*24 + 12*2x + 24*2x + (2x)² = 1408
- 288 + 72x + 4x² = 1408
- 4x² + 72x + 288 - 1408 = 0
- 4x² + 72x - 1120 = 0
- x² + 18x - 280 = 0
- x² - 10x + 28x - 280 = 0
- x(x - 10) + 28(x - 10) = 0
- (x - 10)(x + 28) = 0
1)
2)
- x + 28 = 0
- x = - 28 (discarded as negative)
Correct choice is B
Answer:
a)
.
Substitute all the values in the given relation.
The steps and table is attached below.
b) The relation is not a function.
Since the x =0 and x=3 has the same value. A relation is function when each input has only exact one output. refer the on-to diagram uploaded.
c) The domain is the set of all input values that can be applied into a function y or f(x).
Here all the x values -4,-3,-,-1,0,1,2,3,4 [-4,4] is the domain.
