D. $\frac{21 \: b}{10} - 48$ ✅

Step-by-step explanation:

$- 6( \frac{1}{4} b+ 10) + 4( \frac{9}{10}b + 3) \\ = \frac{ - 6 \: b}{4} - 60 + \frac{36 \: b}{10} + 12 \\ = \frac{ - 3 \: b}{2} + \frac{18 \: b}{5} - 60 + 12 \\ = \frac{ - 3 \: b \times 5}{2 \times 5} + \frac{18 \: b \times 2}{5 \times 2} - 48 \\ = \frac{ - 15 \: b + 36 \: b}{10} - 48 \\ = \frac{21 \: b}{10} - 48$

Maya can run 18 miles in 3 hours, and she can bike 18 miles in 2 hours. When Maya biked for 3 hours and then ran for 1 hour and

solmaris [256]

Answer: 8

Step-by-step explanation: Speed is distance/time

18/3 = 6 miles per hour running

18/2 = 9 miles per hour biking

3 hour bike = 27 miles

1.50 hour run (0.50 because 30 minutes is half of an hour) = 9 miles

27 + 9/3 + 1.50 = 36/4.5 or 8

Convert the angle \theta=310^\circθ=310 ∘ theta, equals, 310, degree to radians.

lozanna [386]

The correct question is
Convert the angle theta equals 310 degree to radians.

we Know that

2pi radians is equals to----------> 360°
then
X radians-------------------> 310°
X=310*2*pi/360°---------> X=5.41 radians

the answer is
5.41 radians

Plot six lines. Each line should pass through the origin and one of the six points. One is done for you.

frutty [35]

<h3>Solution (Line 2): (Refer to graph 1)</h3>

Note that:

Given points: (0, -2) and (1, -4)
Slope formula: Rise/Run
Point slope form formula: y - y₁ = m(x - x₁)

To create the equation of the line, find the slope. Then, use point slope form to find the equation of the line.

Use the slope formula to find the slope.

Rise/Run = Slope
=> Rise = -2; Run = 1
=> Rise/Run = -2/1 = -2

Use the point slope form formula.

y - y₁ = m(x - x₁) = Equation of line.
=> y - (-4) = -2(x - 1) = Equation of line.
=> y + 4 = -2x + 2
=> y = -2x + 2 - 4
=> y = -2x - 2

<h3>Solution (Line 3): (Refer to graph 2)</h3>

Note that:

Given points: (0, -2) and (-4, 3)
Slope formula: Rise/Run
Point slope form formula: y - y₁ = m(x - x₁)

To create the equation of the line, find the slope. Then, use point slope form to find the equation of the line.

Use the slope formula to find the slope.

Rise/Run = Slope
=> Rise = -5; Run = 4
=> Rise/Run = -5/4

Use the point slope form formula.

y - y₁ = m(x - x₁) = Equation of line.
=> y - 3 = -5/4{x - (-4)} = Equation of line.
=> y - 3 = -5/4{x + 4}
=> y - 3 = -5x/4 - 5
=> y = -5x/4 - 2

<h3>Solution (Line 4): (Refer to graph 3)</h3>

Note that:

Given points: (0, -2) and (-3, -5)
Slope formula: Rise/Run
Point slope form formula: y - y₁ = m(x - x₁)

To create the equation of the line, find the slope. Then, use point slope form to find the equation of the line.

Use the slope formula to find the slope.

Rise/Run = Slope
=> Rise = 3; Run = 3
=> Rise/Run = 3/3 = 1

Use the point slope form formula.

y - y₁ = m(x - x₁) = Equation of line.
=> y - (-5) = 1{x - (-3)} = Equation of line.
=> y - (-5) = 1{x + 3}
=> y + 5 = x + 3
=> y = x - 2

Hoped this helped!
