Kevin and his children went into a restaurant and he bought $31.50 worth of hotdogs and drinks. Each hotdog costs $4.50 and each

Musya8 [376]

Answer:

6 hot dogs, 2 drinks

Step-by-step explanation:

let y = number of hot dogs

let x = number of drinks

system:

y = 3x

4.5y + 2.25x = 31.50 (standard form: y = -1/2x + 7)

if you graph the system, lines intersect at (2, 6)

Select all the pairs that could be reasonable approximations for the diameter and circumference of a cirlce 5 meters and 22 mete

bazaltina [42]

Answer:

Option a) circle 5 meters and 22 meters

Step-by-step explanation:

We are given the following information in the question:

A pair of diameter and the circumference is given. We have to find a correct approximations for the diameter and circumference.

a) circle 5 meters and 22 meters

$\text{Diameter} = 5\text{ meters}\\\text{Circumference} = \pi d = 3.14\times 5 = 15.7\text{ meters}$

b) 19 inches and 50 inches

$\text{Diameter} = 19\text{ inches}\\\text{Circumference} = \pi d = 3.14\times 19 = 59.66\text{ inches}$

c) 33 centimeters and 80 centimeters

$\text{Diameter} = 33\text{ centimeters}\\\text{Circumference} = \pi d = 3.14\times 33 =103.62\text{ centimeters}$

Thus, no pair gives a reasonable approximation. Only the circle with diameter 5 and circumference 22 meters have closest approximation.

Is it parallel or is it perpendicular?

zavuch27 [327]

It is parallel, which means that the new line should have the same slope of the given line $y=-5/4 x+7$
and the slope is the coefficient of x
so the slope = -5/4
in order to solve this problem we have to know the equation of the slop
$slope= \frac{y-y1}{x-x1}$
where (x1,y1) is the point by which the new line passes through

$\frac{-5}{4}=\frac{y-(-4)}{x-1}$
$\frac{-5}{4}= \frac{y+4}{x-1}$
-5(x-1)=4(y+4)
-5x +5=4y+16 (by subtracting 16 from both sides)
-5x -11= 4y (divide both sides by 4)
y= $\frac{-5}{4}x - \frac{11}{4}$
