Explanation:

Distance traveled by butterfly at the rate of 34 miles per hour in 2.5 hours
=35 mi/hr × 2.5 hour
=<span><span>35mi</span><span>hour</span></span> ×2.5 <span>hour</span>
=<span>35mi⋅<span>2.51</span>⋅<span>1010</span></span>
=<span>35mi⋅<span>2510</span></span>
=<span>35mi⋅<span>52</span></span>

6. Write the equation of the line in slope-intercept form given the following:
Juliette [100K]

Answer:

y=\dfrac{5}{4}x+1

Step-by-step explanation:

Slope intercept form a equation of a line is given by the following formula:

Slope intercept form:

y=mx+c

Given that, a point is (-4,-4)

i.e.

x=-4,\\y=-4

Slope, m =\frac{5}{4}

Putting the given values in the Slope intercept form equation:

-4=-4\times \dfrac{5}{4}+c\\\Rightarrow -4=-5+c\\\Rightarrow c =1

Putting the value of c and m in the slope intercept form:

y=\dfrac{5}{4}x+1

Use the figure to the right to find the value of PT. T is the midpoint of PQ.
Monica [59]

Answer:

PQ = 42

Step-by-step explanation:

Given

PT = 3x + 3

TQ = 5x - 9

Midpoint, T

Required

Determine PT

First, the value of x has to be calculated;

Since T is the midpoint, then:

PT = TQ

This implies

3x + 3 = 5x - 9

Solve for x

3x - 5x = -3 - 9

-2x = -12

x = -12/-2

x = 6

Length PQ can then be calculated using:

PQ = PT + TQ

PQ = 3x +3 + 5x -9

Collect Like Terms

PQ = 3x+ 5x +3  -9

PQ = 8x -6

Substitute 6 for x

PQ = 8 * 6 - 6

PQ = 48 - 6

PQ = 42
