Step-by-step explanation:
the domain is the interval or set of all valid x-values for the function.
and the range is the interval or set of all valid y-values (functional result values) for the function.
so, we can see here that the function would create results for all x in (- infinity, + infinity). that is the domain.
now, what result values (y-values) are possible ?
we see, that the smallest functional value is y = -2.
and from there all y-values up to +infinity are possible.
so, the range is [-2, +infinity).
please consider the chosen brackets. the "[" means the value is included in the function, a "(" means that that particular interval end value is excluded. anything bigger or smaller might be valid but not this one value.
and infinity is not a value. hence they are not included in such intervals.

Jenny reads a book with 92 pages. Jenny's book has 13 more pages than the book Macy reads. Which equation could you solve to find how many pages, m, Macy's book has?
a m+13=92m plus 13 is equal to 92
b m=92+13m is equal to 92 plus 13
c 92m=1392 m is equal to 13
d 13m=92
Answers
All you do is change M+13=92 by subtracting 13 on both sides so that 13 cancels out on the left and 13 pages are subtracted from 92, and then you get your answer, which is m=79.
You can check your work by adding 13 and 79, and then you will know that that answer is correct

What is a triangular prism?A closed solid with two parallel triangular bases joined by a rectangle surface is known as a triangular prism.
The total surface area of the triangular prism will be
Total surface area = 2(area of the triangle) + 3(area of the rectangle)
The area of the rectangle will be
Rectangle area = 2 x 1
Rectangle area = 2 square cm
The area of the triangle will be
Triangle area = 0.5 x 4 x 2
Triangle area = 4 square cm
Then the total surface area will be
Total surface area = 2 x 4 + 3 x 2
Total surface area = 8 + 6
Total surface area = 14 square cm

Need help with this quick. Find the measure of B and the value of z if ABC~DEF.
Answers
And B = 45
This is because all angles in any triangle is equivalent to 180 degrees. When you have a similar triangle, the angle measures remain consistent, only the side lengths change. Therefore, we know that:
Angle D = 105 degrees
Angle C = 30 degrees
And angle B = (10z - 5) degrees
105 + 30 = 135
180 - 135 = 45
10z - 5 = 45
10z = 50
z = 5
So, angle B = 45 and z = 5

Which function represents a linear function
Answers
Answer:
D. y = -4/5x + 10
Step-by-step explanation:
If you graph it, whether that be on paper or typing the equation out on a website so it can do the graphing for you, it's a straight line with a negative slope unlike the other choices. Therefore, it's a linear function. A quick tip is that, usually, a linear function can be easily shown in the form of y = mx + b (slope-intercept form), and that's the exact form y = -4/5x + 10 is in. y being y (dependent variable, or result/output), -4.5 being m which represents the slope, x being x (independent variable, or input), and +10 being b which represents the y-intercept. If the x is in the denominator like in y = 5/x - 3, it's very likely that it's not a linear function.

3(8w + 6) write the expression in two other ways
need help asap
Answers
Answer:
1) 24w + 18
2) 6(4w + 3)
Step-by-step explanation:
Explanation for 1)
Use the Foil method for factoring by multiplying each number inside the bracket [8w + 6] by the number outside the brackets [3]
3*(8w + 6)
3 * 8w + 3 * 6
= 24w + 18
Explanation for 2)
By using the final product in 1) [24w + 18], we can facour it further by using GCF (Greatest Common Factor)
We have to determine first what is the greatest common factor of 24w, and 18
Its 6
So we use 6, and divide it by what we got in explanation 1 to find our 2nd way of writing the expression
24w/6 + 18/6
= 6(4w + 3)
Don't forget to put whatever you divided those numbers by outside of the bracket
Hope this helps :)
Answer:
Step-by-step explanation:
Given
3(8w + 6)
Question
Write in 2 different ways.
Method One
Use the distributive property to remove the brackets.
3(8w + 6) Given. Remove the brackets. Notice both results
3*8w + 3 * 6 Combine

Method 2
Take out another common factor. 2 is another common factor.
3(8w + 6)
3*2 (4w + 3) Combine
6 ( 4w + 3)
