Answer:

z = 1.75xy

Step-by-step explanation:

Given z varies jointly as x and y then the equation relating them is

z = kxy ← k is the constant of variation

To find k use the condition z = 7 when x = 2 and y = 2, then

7 = k × 2 × 2 = 4k ( divide both sides by 4 )

1.75 = k

z = 1.75xy ← equation of variation

M: -1/2 Point: (-1, 3) Solve for y=mx+b<br> Help
ohaa [14]

Answer:

y= (-1/2)x+(5/2)

Step-by-step explanation:

equation point slope

(y-y1)=m(x-x1)

y-3 = -1/2(x+1) add -3 to both sides and distribute

y=( -x/2) +(-1/2)+3 rewrite 3 as 6/2

y=(-1/2)x +(-1+6/2) solve

y= (-1/2)x+(5/2)

Charlotte spent 1/2 of the day shopping at all. She spent 1/4 of this time trying on jeans. What fraction of the day did Charlot
RideAnS [48]

Answer:

Charlotte spend \frac{1}{8} of day trying on jeans

Step-by-step explanation:

Charlotte spent part of day on shopping = \frac{1}{2}

She spent part of shopping time on trying jeans =\frac{1}{4}

We are supposed to find What fraction of the day did Charlotte spend trying on jeans.

She spent fraction of the day in trying jeans = \frac{1}{2} \times \frac{1}{4}

She spent fraction of the day in trying jeans = \frac{1}{8}

Hence Charlotte spend \frac{1}{8} of day trying on jeans
