Answer:

Step-by-step explanation:
The equation of the line with the slope
and passing through the point
is

In your case,

Hence, the equation of the line is

Ok, so the quadratic coefient is 1, so great
take 1/2 of the linear coefient and square it
10/2=5, (5)^2=25
add that to both sides
x^2+10x+25=7+25
factor perfect square trionomial
(x+5)^2=32
squaer root both sides
x+5=+/-4√2
minus 5
x=-5+/-4√2
x=-5+4√2 and -5-4√2

Answer:
3/10
Step-by-step explanation:
1/5 of <u>total</u> income - spent on car
<u>remainder</u><u> </u> income = 4/5
3/8 of <u>remainder</u><u> </u>= 3/8 ×4/5 = 3/10(of total income spent on rent)
the word "<u>of</u>" means you can find it by multiplication
e.g. 2 of 1/2 means 2 × 1/2 which is 1
