Answer:

4. None of the above

Step-by-step explanation:

Change the function to

y - 10 + 3x = 0

then put y values and x values in in each for every set.

for example

in set 1:

y = 10 - 3x

13 = 10 - 3(-1)

13 = 13 .........cancels out to be 0 as all the other does the same.

For every set the answer at the end is coming 0 whereas it should only be above or less than 0 as he needs more 2 dollar to buy another tacos.

Can someone help me with this question.

Doss [256]

Answer:

Step-by-step explanation:

note that x = - 3 < - 2, thus

f(x) = $\frac{1}{x}$ , then

f(- 3) = $\frac{1}{-3}$ = - $\frac{1}{3}$

This table gives a few (x,y)(x,y)left parenthesis, x, comma, y, right parenthesis pairs of a line in the coordinate plane. -28 -

Serhud [2]

Answer:

The y-intercept is y = 2

Step-by-step explanation:

A linear function has the following format:

$y = mx + b$

In which m is the slope and b is the y-intercept, which is the value of y when x = 0.

We are given these three points:

(-28, -54)

(-21, -40)

(-14, -26)

We use two of them to build a system, to find values for m and b.

(-28, -54)

This means that when $x = -28, y = -54$

$y = mx + b$

$-54 = -28m + b$

$28m = b + 54$

$m = \frac{b + 54}{28}$

(-21, -40)

This means that when $x = -21, y = -40$

$y = mx + b$

$-40 = -21m + b$

$-40 = -21\frac{b + 54}{28} + b$

$-40 = \frac{-21b - 1134 + 28b}{28}$

$7b - 1134 = -40*28$

$7b = 14$

$b = \frac{14}{7}$

$b = 2$

The y-intercept is y = 2

A group of friends spent 1, 0, 2, 3, 4, 3, 6, 1, 0, 1, 2, and 2 hours online last night. What are the 1st and 3rd quartiles for

Ostrovityanka [42]

Arrange the numbers from smallest to largest:

0,0,1,1,1,2,2,3,3,4,6

Split the data in the middle, since there is an odd amount of numbers take an even amount on each side:

0,0,1,1,1,2,2,3,3,4,6

Lower half: 0,0,1,1,1

Higher half: 2,3,3,4,6

1st quartile is the middle value of the lower half: 1

3rd quartile is the middle value of the higher half: 3

Numeric values get larger as you travel to the right of the number line true or false

aivan3 [116]

Answer:

True

Step-by-step explanation:

a negative number like -6 which would be found on the left of the number line is not larger than 2 which is found on the right side of the number line.
