I need some help with this math problem. I've had it explained to me two different ways. If x= -3 then what would be the answer

to x^2 + 5 = ? My teacher says it is 14 but then someone else mentioned that order of operations says that the answer is -4. Help!!

Answer:

The square root of x will be evaluated first before the addition of 5. Hence (-3)^2 = 9 and 9 +5 = 14, as per your teacher's answer, which is correct. The answer would not be -4.

\text{You have to solve by plugging in -3 to x:}\\\\(-3)^2+5\\\\\text{Solve:}\\\\(-3)^2+5\\\\9+5\\\\\boxed{14}\\\\\text{Your answer would be 14. The teacher is correct}

A scatter plot contains a trend line that passes through points (2, 5) and (3, 7). Does this trend line illustrate a correlation
zalisa [80]
Given that the scatter plot contains a trend line that passes through (2,5) and (3,7),
the slope of this line is given by:
slope,m=(7-5)/(3-2)=2/1=2
this shows a positive slope, but other than this we cannot draw any further details concerning the points such as the correlations, hence the answer is:

Two numbers are co-prime if they have no common factors (other than
Triss [41]

Answer:

See below.

Step-by-step explanation:

a)

105/3 = 35

35/5 = 7

7/7 = 1

429/3 = 143

143/11 = 13

13/13 = 1

105 = 3 * 5 * 7

429 = 3 * 11 * 13

Not co-prime

For the other parts of the problem, do the same I did above. Find the prime factorizations of both numbers, and see if they have any prime factors in common.

Brenda collected this data from an experiment.
Gelneren [198K]

Answer:

7.04

Step-by-step explanation:

To get the value of residual of the data point, we simply substitute 11 for t

The substitution equation is h = 0.6t + 0.44

Substituting 11, we have

h = 0.6(11) + 0.44

h = 6.6 + 0.44

h = 7.04

How can complex fractions be used to solve problems involving ratios
strojnjashka [21]
When you have ratios, and some unknowns, you can create complex fractions from them. Bring them to the same denominator, and solve for x.

Example - we have this proportion:
2-x
5-45
And we can change it into fraction:
\frac{2}{5}=\frac{x}{45}

\frac{2*9}{5*9}=\frac{x}{45}

\frac{18}{45}=\frac{x}{45}
18=x

In case of more complex fractions it may come in handy.
