The answers are A, C, and D. B is not a correct answer because 4 times 11 is not 42
Answer:
D choice.
Step-by-step explanation:
Pass through (0,-4) means that <u>the</u><u> </u><u>graph</u><u> </u><u>intercepts</u><u> </u><u>y-axis</u><u> </u><u>at</u><u> </u><u>(</u><u>0,</u><u>-</u><u>4</u><u>)</u>
Therefore, our b is -4
Slope = 1 means that the value of m is 1. Substitute m = 1.
Therefore, the answer is D choice.
Answer: The zero of a function is any replacement for the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.

Answer:
1. 8.3%
Step-by-step explanation:
Relative error = absolute error/expected measurement
The expected measurement is given as 6 ft.
Now, the absolute error is usually equal to half of a unit of the measure.
This means the absolute error in this case is ½ × 1 = 0.5 ft
Thus, the exact measurement will be;
6 ± 0.5
Thus;
Relative error = 0.5/6
Relative error = 0.083
Expressing it in percentage gives 8.3%
Answer:
5
Step-by-step explanation:
x^2-7x=30
x^2-7x-30=0
a = 1, b = -7, c = -30
sqrt(b^2-4ac)
sqrt(49+120)
sqrt(169)
13
-b +/- 13
7 + 13 = 20
7 - 13 = -6
2a = 2
20/2 = 10
-6/2 = -3
we know x>0, so it cant be -3. so now its just 10 - 5
