Answer:

$4.50

Step-by-step explanation:

First step is to find the price per orange. You can do this by dividing total cost by oranges bought. See below.

$4 \div 8 \\ = .50$

Now to find the amount of 9 oranges, you'd multiply price per orange by the specified amount needed (so 9)

$9 \times .50 \\ = 4.50$

Law Incorporation [45]

Using proportions, the number of 1/4 cup servings that she can make is given by:

B. 3 and 5/9.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

For this problem, considering that Susie has 8/9 of a cup, the following <u>rule of three</u> is established:

1 serving - 1/4 cups

x servings - 8/9 cups

Applying cross multiplication:

$\frac{x}{4} = \frac{8}{9}$

9x = 32

x = 32/9

Since 32 divided by 9 has quotient 3 with remainder 5, the correct option is given by:

B. 3 and 5/9.

X and y-intercept of y=X-5

aksik [14]

The x-intercept is when y = 0
y = x - 5 → 0 = x - 5 → x = 5

The y-intercept is when x = 0
y = x - 5 → y = 0 - 5 → y = - 5

Answer: x-intercept is (5, 0), y-intercept is (0, -5)

What is the equation of the line that passes through the point (-6, -8) and has a slope of 1/3

ivanzaharov [21]

Answer <u>(assuming it can be in point-slope form)</u>:

$y + 8 = \frac{1}{3} (x+6)$

Step-by-step explanation:

With the given information, we can use the point-slope formula, $y-y_1 = m (x-x_1)$ , to write the equation of the line. Substitute values for the $m$ , $x_1$ , and $y_1$ in the formula to do so.

The $m$ represents the slope, so substitute $\frac{1}{3}$ in its place. The $x_1$ and $y_1$ represent the x and y values of one point the line intersects, so substitute -6 for $x_1$ and -8 for $y_1$ . This gives the following answer and equation (just make sure to convert the double negatives into positives:

$y-(-8) = \frac{1}{3} (x-(-6))\\y + 8 = \frac{1}{3} (x+6)$
