Answer:

I, III, and IV

One of my friends explained this very well (Gmany):

"Step-by-step explanation:

The slope-intercept form of an equation of a line:

m - slope

b - y-intercept → (0, b)

If m > 0, then the function is increased

If m < 0, then the function is decreased

We have

- the function is increased

- the y-intercept is -4 → (0, -4)

Therefore the line passes through III, IV and I quadrant.

========================================

<, ≤ - shaded region below the line

>, ≥ - shaded region above the line

========================================

We have → ≤ - shaded region below the line.

Therefore the unequal the inequality exist in I, III and IV quadrant."

The picture shows this too.

WILL GIVE BRAINLIEST! Someone please graph these, I can't graph them.

nadezda [96]

Answer:

see attached image

Step-by-step explanation:

F(x) = 2x + 5 is a linear graph because the exponent on x is 1. I tell my students that think of graphs having one less turn/corner that the value of the highest exponent. so since 2x has a exponent of 1, 1-1 =0 so it has no turns or its a straight line.

this has a slope of 2 or 2/1 or up 2 and right 1 from the y intercept which is 5

so mark 5 on the y axis and a from there go up 2 and right 1 and make another point. Join these points and you have your graph

and

g(x) = (x-5)/2 is its inverse and is found:

F(x) = 2x + 5 write it this way y = 2x + 5

now swap the x and y x = 2y - 5

solve for y

x = 2y + 5

- 5 -5

x - 5 = 2y

/2 /2

(x-5)/2 = y

it can be written as y = x/2 - 5/2

and graphed the same way as above with a 1/2 slope and -5/2 y intercept

Which equation are true for x=-2 and x=2 check all that apply

ki77a [65]

1 it is true
${x}^{2} - 4 = 0 \\ {x}^{2} = + 4 \\ x = \sqrt{4} = 2$
2 it's not true
${x}^{2} = - 4$
3 it's not true
$3 {x}^{2} + 12 = 0 \\ 3 {x}^{2} = - 12 \\ {x}^{2} = \frac{ - 12}{3} = - 4 \\$
4 it's true
$4 {x}^{2} = 16 \\ {x}^{2} = \frac{16}{4} = 4 \\ x = \sqrt{4} = 2$
5- it's true
${2(x - 2)}^{2} = 0 \\ {(x - 2)}^{2} = 0 \\ x - 2 = 0 \\ x = 2$

32) (a)-(c) pre calculus

Harrizon [31]

Well, remember we can't take the square root of a negative

so we see that we have $\sqrt{1-x^2}$
so find those values that take sqrt of a negative and restrict hem from the domain
anny value greater than 1 and less than -1
so domain is from -1 to 1, including those numbers
D=[-1,1]

a. D=[-1,1] or from -1 to 1 is domain

b. for a TI-84, go to y-editor then input $4x \sqrt{1-x^2}$ for y1

c. for a TI-84, click 2nd then window (gets to tbset) scrol down to set Δx to 0.1, then cilick 2nd again then click graph (to select table) and scroll down till you see that value of y that is the biggest, that value is x=0.7

A. domain is from -1 to 1
B. use your brain or google the instructions for your calulator
C. at x=0.7

22nd term: 28, 23, 18, 13,..

Verizon [17]

Answer:

The 22nd Term is -77.

Step-by-step explanation:

The pattern is -5. If you subtract 5 from each starting number you'll get the following number.

Ex: 28 - 23 = 5

23 - 18 = 5

18 - 13 = 5

Subtract 5, 22 times and you will get -77.

I hope this was the most brainliest answer, thank you for letting me help you !
