Y = 2x + 7 => f(x) = 2x + 7
Answer:
That's hard u should scan and look at other ppl that answered that
X<-7
times both sides by 2
2x<-14
add 14 both sides
2x<-14
<span>87 24/25 ...this is a mixed fraction ..so in order to get in in decimal we first need to convert it into unlike fraction ..for that we do the following ...
</span>
<span>87 24/25
</span>=> multiply the whole number and the denominator ..
=>87 X 25 = 2175
=>now add the numerator to this product ...
=>2175 + 24 = 2199 ..
=> so now we get an unlike fraction which when we divide we get the answer in decimals ..
=> 2199/25 = 87.96 ...
that is ... 87 24/25 in decimals ...
Hope it helps !!!
The possible solution is having 30 rolls of wallpaper and 20 can of paints or 30 rolls of wallpaper with 46 can of paint.

Inequality</h3>
Inequality is the non equal comparison of two or more numbers and variables.
Let x represent the number of wallpapers and y represent the number of cans.
He needs at least 30 rolls of wallpaper and at least 20 cans of paint. Hence:
x ≥ 30 (1);
y ≥ 20 (2)
Also:
32x + 28y ≤ 2240 (3)
Plotting the 3 equations using geogebra online graphing tool, the possible solution is:
(30, 20), (30, 46)
The possible solution is having 30 rolls of wallpaper and 20 can of paints or 30 rolls of wallpaper with 46 can of paint.
