Answer:

146

Step-by-step explanation:

To find any y-coordinate of a line, plug in the x-coordinate 50 into the equation and simplify. The result will be y.

Plug in x = 50 into y = 3x - 4.

y = 3(50) - 4

y = 150 -4

y = 146

The y-coordinate is 146.

What is the range of the function y = 3x + 2 when the domain is {-3, 0, 2}?

Firlakuza [10]

Answer:

{-7, 2, 8}

Step-by-step explanation:

We see that the domain is limited to three x-values: -3, 0 and 2. To find the range (which is the set of all y-values) we just need to plug-in these x-values and find the corresponding y-values.

So our equation is:

y = 3x + 2

Then we substitute for the x-values:

y = 3(-3) + 2

y = -9 + 2

y = -7

y = 3(0) + 2

y = 0 + 2

y = 2

y = 3(2) + 2

y = 6 + 2

y = 8

So our range would be {-7, 2, 8}.

Suppose h is a function such that h(2) = −3, h'(2) = 3, h''(2) = 4, h(5) = 5, h'(5) = 6, h''(5) = 12, and h'' is continuous ever

Answer:

Step-by-step explanation:

It seems like your question is not complete.

So I will asume that it is like the one in the image.

But probably the answer is not 3 if the range is different from (1-2), eventhough, you just have to follow the same steps.

Vikentia [17]

Answer:

Step-by-step explanation:

The coefficient of determination = $r^{2} = 0.885^{2}$ = 0.7832

It means about 78% variation in waist size of males can be explained by their weight and about 23% can not be explained.
