Write an equations in point-slope form for a horizontal line that passes through (-4, -1)
Flura [38]

Answer:

Y=-1; y+1=0(x+4)

Step-by-step explanation:

Point slope form: y-y1=m(x-x1)

A horizontal line has a slope of "0" therefore our "m" value is 0

So

y+1=0(x+4)

Y+1=0x+0

y=-1

Hope this helps!

Given 16 = −5 + z4solve for z
AysviL [449]
Hi,

16 = - 5 + z4 \\ - 4z + 16 = - 5 \\ - 4z = - 5 - 16 \\ - 4z = -21

Now just divide both sides of equation by -4.

z = \frac{21}{4}

Simplify:

z = 5 \frac{1}{4} \: \: \: \: \: \: \: \: \: \: \: \: \: fraction \: result

Decimal form:

z = 5.25 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: decimal \: result

Hope this helps.

Mai biked 6\frac{3}{4} miles today, and Noah biked 4\frac{1}{2} miles.
Alinara [238K]

It was 1.5 times the length of Noah's bike ride as Mai’s bike ride.

The problem we dealing with is related to mixed numbers which are referred to as mixed numbers and could be the whole number, and a proper division spoke together. It for the most part speaks to a number between any two whole numbers.

Since we are providing mai's rate which is  6 3/4  miles and Noah's  rate of 4 1/2 miles, So in  order to find the time the length of Noah's ride is compared to Mal's, we just need to divide the given rates by each other

=> 6 3/4 divided by 4 1/2,  

=> 27/4 divided by 9/2, (The result is an improper fractions)

=> 27/4 X 2/9

=>3/2

=> 1.5

Flauer [41]

Answer:

13402

Step-by-step explanation:

PV= $299,132

I/YR= 4.48% or 0.0448

N= 216

PMT= $13402

(Excel works great with this and will solve it for you, use the PMT function and insert the numbers provided.  It will show a (-) but that is because a positive PV is placed.)
