Determine whether quadrilateral ABCD with vertices A(–4, –5), B(–3, 0), C(0, 2), and D(5, 1) is a trapezoid. Step 1: Find the sl

Pani-rosa [81]

Answer:

The Slope of AB: 5/1

The Slope of DC: -1/5

The Slope of BC: 2/3

The Slope of AD: 2/3

The quadrilateral is a trapezoid because BC and AD are parallel to each other while AB and DC are congruent.

If 10 cups of ice cream are separated into 1/5 cup sample serving how many samples can be served

cestrela7 [59]

Answer:

50 Samples

Step-by-step explanation:

Divide the total cups of ice cream (10) by the sample amount (1/5)

$\frac{10}{\frac{1}{5} }$

10 ÷ 1/5

Use the keep change flip rule.

$\frac{10}{1}*\frac{5}{1} = 50$

Write the slope-intercept equation of the line parallel to 5y = 2x + 20 that goes through (-1, 3)

katen-ka-za [31]

Answer:

$y = \frac{2}{5}x + 3\frac{2}{5}$

Step-by-step explanation:

This line was never finished, so you finish it like this:

$\frac{5y}{5} = \frac{2x + 20}{5} → y = \frac{2}{5}x + 4$

3 = −⅖ + b

$3\frac{2}{5} = b \\ \\ y = \frac{2}{5}x + 3\frac{2}{5}$

Parallel Lines have SIMILAR <em>RATE OF CHANGES</em> [<em>SLOPES</em>], so ⅖ remains the way it is.

I am joyous to assist you anytime.
