Determine the value of r so the line passing through each pair of points has the given slope

1 answer:

4 0

We can use the slope formula to solve this one:
$m=\frac{y_2-y_1}{x_2-x_1}$
$\frac{1}{2}=\frac{2-3}{r-6}$
$(r-6)=2(-1)$
$r-6=-2$
$r=4$

E line plot below shows the amount of water Rickayla drinks in 10 days. Part a: how many cups of water did Rickayla drink in 10

Levart [38]

Answer:

$Total = 23\frac{1}{4}$ cups

Step-by-step explanation:

Incomplete question.

See attachment for line plot

Required

Total cups drank in 10 days

The number of x at the top of each dataset represent the frequency (i.e. number of cups) drank on that day.

To get the total, we simply multiply this frequency by the accompanying dataset.

So, we have:

$Total = 2 * 1\frac{1}{2} + 1 * 1\frac{3}{4} + 2 * 2 + 2 * 2\frac{3}{4} + 3 * 3$

Express fractions as improper fraction

$Total = 2 * \frac{3}{2} + 1 * \frac{7}{4} + 2 * 2 + 2 * \frac{11}{4} + 3 * 3$

Evaluate each product

$Total = 3 + \frac{7}{4} + 4 + \frac{11}{2} + 9$

Take LCM

$Total = \frac{12+ 7+16+22+36}{4}$

$Total = \frac{93}{4}$

$Total = 23\frac{1}{4}$

What is the midpoint of line segment AB?

Elza [17]

Answer

Midpoint = (3, 5.5)

Step by step explanation

Here we have to use the midpoint formula.

Midpoint = ( $\frac{x1 + x2}{2} , \frac{y1 + y2}{2} \\$ )

Here the point A = (-1, 8) and B = (7, 3)

x1 = -1, y1 = 8, x2 = 7 and y2 = 3

Now plug in these values into the formula.

Midpoint = ( $\frac{-1 + 7}{2} , \frac{8 + 3}{2}$

= (6/2, 11/2)

= (3, 5.5)

Therefore, the midpoint the line segment AB is (3, 5.5)

Thank you.

Sherri saves nickels and dimes in a coin purse for her daughter. The total value of the coins in the purse is $0.95. The number

forsale [732]

I’m guessing that this is for systems of equations?
n - nickels
d - dimes

These are the equations you start off with.
n = 5d-2
0.95 = 0.10d+0.05n

Substitute the top equation for n into the variable n in the bottom equation.
0.95 = 0.10d+0.05(5d-2)

Solve for d.
0.95 = 0.10d+0.25d-0.10
1.05 = 0.35d
3 = d

Substitute d into the top equation and solve for n.
n = 5(3)-2
n = 15-3
n = 12

There are 3 dimes and 12 nickels in the coin purse! Hope this helped <3
