Tonya bought gifts for her family that cost $25, $14, $33, and $19. She has to buy one more gift and wants her mean cost to be $
Brums [2.3K]

____________________________________________________

Answer:

Your answer would be $34.

____________________________________________________

Step-by-step explanation:

In order to get the mean cost that she wants from the gift, we would need to get the numbers that we already had, and have another set of row with the amount of gifts she needs with the mean she wants.

Here is how it should look like:

$25  $14  $33  $19    x

$25  $25  $25  $25 $25

We are trying to find the number for "x"

Therefore, we would need to use the process of adding, then subtracting after.

Lets add:

25+14+33+19=91\\\\25+25+25+25+25=125

What we would do now is subtract the numbers in order to get the price that Tonya wants from her gift, if she buys another gift.

125-91=34

Tonya should spend $34 on her last gift.

$34 should be your FINAL answer

Answer:

y-intercept: -5

Slope: 4

Equation: y = 4x - 5

Step-by-step explanation:

✔️The y-intercept is the value of y when x = 0. From the table of values, it shows that when x = 0, y = -5. Therefore:

y-intercept (b) = -5

✔️using two pairs from the table, (1, -1) and (2, 3):

Slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{3 -(-1)}{2 - 1} = \frac{4}{1} = 4

Slope = 4

✔️To write an equation for the function, substitute m = 4, and b = -5 into y = mx + b.

Thus:

y = 4x +(-5)

y = 4x - 5

(-19+7i)-(29+32i)=<br><br> in the form (a+bi)
olga_2 [115]
ANSWER

-48-25i

EXPLANATION

We want to simplify the expression,

(-19+7i) - (29+32i)

Let us expand the bracket to obtain,

-19+7i-29-32i

We now group the complex number parts and real number parts.

-19 -29+7i-32i


We simplify further to obtain,

- 48-25i


This is in the form,

a+bi

where

a=-48

and

b=-25
