# Does anyone knows how to do this I don’t understand it.

Answer: Between the two, the difference in x is -1 and the difference in y is 3.
Y's difference is rise, and x's difference is run.
Divide rise over run to get the slope.
3 / -1 = -3
So the slope is -3, eliminating 2 and 4.
The y-intercept that fits the graph is 7, not -7.
That means the correct equation is C.
Hope this helps!

Thirty-five percent of students at Jones High School ride the bus. Two hundred seventy-three students ride the bus. How many students go to Jones High School? A) 96 B) 560 C) 694 D) 780

Answer: D) 780 is the right option. The total number of students go to Jones High School=780.

Step-by-step explanation:

Let the total students go to the Jones High School be 'x'.

Percentage of students ride the bus=35%

Number of students ride the bus= 273

According to the given question,

35% of x=273

he total number of students go to Jones High School=780.

when I solved it I got 750.(273÷.35=780)

a bucket holds 243.5 oz of water. The bucket loses 0.3 oz of water per second.In how many seconds will the bucket be 40% full

ok so
t=time in seconds
therefor the smount lost for t seconds is 0.3 ties t or 0.3t
loss so it is ngative
-0.3t
the question is
243.5-0.3t=40% of 243.5
first, find 40% of 243.5
percent means partst out of 100 so
40%=40/100=0.4
'of' means multiply
40% of 243.5=0.4 ties 243.5=97.4
now the question is
243.5-0.3t=97.4
for ease, multiply whole equation by 10 to make no decimals
2435-3t=974
subtract 2435 from b oth sides
-3t=-1461
divide both sides by -3
t=487

answer is 487 seconds (aka 8 mins, 7 secons)

487 seconds

Which phrase best describe the translation from the graph y = 2(x-15)^2+3 to the graph of y =2(x-11)^2+3?

f(x - n) - shift the graph n units right

f(x + n) - shift the graph n units left

f(x) - n - shift the graph n units down

f(x) + n - shift the graph n units up

----------------------------------------------------------------------------

y = 2(x - 15)² + 3

y = 2(x -11)² + 3 = 2(x - 15 + 4)² + 3

Answer: shift the graph of y = 2(x - 15)² + 3 four units left.
