Answer:

y = 2x + 10

Step-by-step explanation:

We are given the slope of the line and the coordinates of one point on the line. Thus, we use the point-slope formula y - k = m(x - h). Here m = 2, h = -3 and k = 4. Therefore we have:

y - 4 = 2(x + 3)

which can be rewritten as y = 2x + 6 + 4, or y = 2x + 10 (Answer D)

ss7ja [257]

Let x be the number of rolls of wallpaper that you can buy to decorate your kitchen. Since each roll costs $10, the total cost for x rolls is 10x. This value should be not be more than $50. The inequality that is best described is
10x ≤ 50
Solving for x gives an answer of x ≤ 5.

The High Roller, a giant ferris wheel in Las Vagas, casts a 242-foot shadow. A 6’3” tall man standing nearby casts a 2 3/4-foot

Ira Lisetskai [31]

Answer:

550ft

Step-by-step explanation:

Simple napkin math, so you know what both shadows are you need to find how tall the High Roller is we will use X for this.

$\frac{242ft}{6'3"} x \frac{x}{2'9"}$

Im not 100% I set it up right but essentially 242 divided by 2'9" and that equals 88

Take 88 and multiply that by 6'3" and you get your Height for the High Roller

What I did their was I scaled the humans height to that of the High Roller dividing it gives you a number you can use to scale the height of that human to how it should scale to the High Roller, which is why I took 88 and multiplied it by the human's height.

Hope this helped :)
