She starts out with 3 dollars, and then she found 75 cents. 5 quarters are equal to $1.25.
The equation would be: (3 + 0.75) - 1.25

3 + .75 - x = 5(.25)
3.75 - x = 1.25
-3.75 -3.75
-x=-2.5
x=2.5
she spent $2.50

I don't understand how are you supposed to do this

never [62]

Answer:

Scatter plots can be a little confusing, but all you need to do is look for an association (what direction the dots appear to be going in). Positive association resembles this / whereas negative association resembles this / flipped the other way. It could also be a curved line, which would be a nonlinear association. If it appears to have no direction at all it has no association. Other wise, all you have to do is read the data to answer the questions. e.g. for the first question find the highest score in the right side of the table and then the corresponding number in the left side. Hope this helps!

If polynomial p(x) is divided by x + 4, the quotient is x^2-7x+34-144/x+4. Which of the following must be true?

Ber [7]

Answer:

B. P(-4)=-144

Step-by-step explanation:

From the question, we have that:

$\frac{p(x)}{x + 4} = {x}^{2} - 7x + 34 - \frac{144}{x + 4}$

This implies that:

$p(x)=(x + 4)( {x}^{2} - 7x + 34) - 144$

To find p(-4), we put x=-4

$p( - 4)=( - 4+ 4)( {( - 4)}^{2} - 7 \times - 4 + 34) - 144$

$p( - 4)=( 0)( {( - 4)}^{2} - 7 \times - 4 + 34) - 144 = - 144$

To find p(0), we put x=0 to get:

$p( 0)=( 0+ 4)( {( 0)}^{2} - 7 \times 0+ 34) - 144$

$p( 0)=(4)( 34) - 144 = - 8$

The correct answer is B

Find the area of a triangle with a base of 7.5 m and a height of 4*

oksian1 [2.3K]

Answer:

15 units²

Step-by-step explanation:

Hi there!

$A=\displaystyle\frac{1}{2} bh$ where <em>b</em> is the base and <em>h</em> is the height

Plug in the base (7.5) and height (4):

$A=\displaystyle\frac{1}{2} (7.5)(4)\\\\A=\displaystyle\frac{1}{2} (30)\\\\A=15$

Therefore, the area of the triangle is 15 units².

I hope this helps!
