Answer:

y = x + 2

Step-by-step explanation:

What is the value of y = 7 – 2c when x =4? When x = 4, y =?

Effectus [21]

The y -intercept of the graph of an equation is the y -coordinate of the point in the xy -plane where the graph intersects the y -axis. Thus the y -intercept can be found by setting x = 0

The distance between (2, 0) and (5, -1) is: 9. 0. 10. <img src="https://tex.z-dn.net/?f=%20%5Csqrt10" id="TexFor

Sidana [21]

Distance = square root ((x2 - x1)^2 + (y2 - y1)^2)
(2,0)...x1 = 2 and y1 = 0
(5,-1)..x2 = 5 and y2 = -1
sub and solve
d = sqrt ((5 - 2)^2 + (-1 - 0)^2)
d = sqrt ((3^2) + (-1^2))
d = sqrt (9 + 1)
d = sqrt 10 <==

Eve is organizing a race to raise money for a local children's hospital. She makes $20 for each 5K participant and $45 for each

Nastasia [14]

Answer: $20x +45y=9500$ is the linear equation.

yes, it is possible.

Step-by-step explanation:

given data:

we were told that she would make $20 for each 5K participant and $45 for each 10K participant.

cost of each 5k participant = $20

cost of each 10k participant = $45.

her target = $9500

solution:

let y represent the 10k

let x represent the 5k participant

the linear equation for this scenarios is

$20x +45y=9500$

(b.) possibility of having 220 participant in the 5k race.

$\\20(220) +45y=9500\\4400 + 45y = 9500\\45y = 9500- 4400\\45y = 5100\\y = \frac{5100}{45} \\y = 113$
