1 answer:

4 0

$\frac{d}{-3} \leq -6 \\ \\ - \frac{d}{3} \leq -6 \\ \\ -d \leq -6 \times 3 \\ \\ -d \leq -18 \\ \\ d \geq 18 \\ \\$

The final result is: d ≥ 18.

In March, Delphine's house had 40% more snowfall than in February. Delphine's house had f centimeters of snowfall in February.

slamgirl [31]

Answer: Options 'C' and 'E' are correct.

Step-by-step explanation:

Since we have given that

Quantity of snowfall in February at Delphine's house be f centimeters

Quantity of snowfall in March at Delphine's house be 40% more than in February.

According to question,

$40\%\ of\ f=0.4f\\\\Therefore,\\\\f+0.4f=1.4f$

So, Options 'C' and 'E' are correct.

i.e. C) 1.4f

E) $\frac{4}{10}f+f$

Estefani‘s house is at point E (3,-2) and Jasmin’s house is at point J (-5,3). Jasmin’s house is the Mid-point of Estefani’s hou

The formula for midpoint is

( $\frac{x_{1}+x_{2}}{2}$ , $\frac{y_{1}+y_{2}}{2}$ )

Look at the image below to see the line segment of Estefani's (A), Jasmin's (M), and Preston's (B) houses. Keep in mind that the segment shown below is not accurate in regards to how the line segment formed by Estefani's, Jasmin's, and Preston's houses. It is simply there so you can picture the segment better.

In this case:

$x_{1} =3\\x_{2} =unknown\\y_{1} =-2\\y_{2} =unknown$

^^^Plug in these number into the formula given above...

( $\frac{3+x}{2}$ , $\frac{-2 + y}{2}$ )

To find what x is (a coordinate of Preston's house) you must take the x-value part of the midpoint equation ( $\frac{3+x}{2}$ ) and set it equal to the x-value of the midpoint (-5). Then you must solve for x:

$\frac{3+x}{2}$ = -5

3 + x = -5 * 2

3 + x = -10

x = -10 - 3

x = -13

To find what y is (a coordinate of Preston's house) you must take the y-value part of the midpoint equation( $\frac{-2 + y}{2}$ ) and set it equal to the y-value of the midpoint (3). Then you must solve for y:

$\frac{-2 + y}{2}$ = 3

-2 + y = 3 * 2

-2 + y = 6

y = 6 + 2

y = 8

The coordinate of Preston's house is:

(-13, 8)
