Ethan had planned to visit his local post office on Saturday to exchange £400
for euros. The exchange rate for that day was £1 = 1.25 €
However, due to unforseen circumstances, Ethan arrived at the post office after
it closed on that day. He therefore had to wait until the following Monday to
exchange his £400 for euros. The exchange rate on Monday was £1 = 1.20 €
a) How many fewer euros did he receive due to this delay? 20 fewer euros
b) What percentage loss was caused by this delay?

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17

step-by-step explanation:

mark brainliest and have a great day!

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
