Answer:
Answer is 79 and 28
Step-by-step explanation:
Let two numbers be x and y.
x + y = 107. --> 1
x - y = 51 -->2
solving above equations,
2x = 158
x =79
y = 28
Answer:
There are no x-intercepts.
Step-by-step explanation:
To find an x intercept we have to find where y = 0
So set the equation equal to zero



Since the number under the radical is negative, we know there are no real solutions, and therefore there are no x-intercepts.
This is shown on the graph.
Answer: She had 27.2% correct.
Step-by-step explanation: To find the percent, we can divide the part and whole then multiply the quotient by 100. After that we'll need to convert the percent to a decimal. In mathematical terms, the formula will be,

40% will be the part and 68% will be the whole.
<u><em>Step 1.</em></u>
Convert 40 into a decimal by dividing it by 100.
40 ÷ 100 = 0.4
<u><em>Step 2.</em></u>
Multiply 0.4 by 68.
0.4 × 68 = 27.2
Hence, she had 27.2% correct.
