Y=18-7x/-4
gradient = 7/4
parallel lines, same gradient.
y--7=7/4(x-2)
y=7x-14-28/4
y= (7x + 14)/4
3 goes into both 3x and 18
Answer:
10
Step-by-step explanation:
given

we first need to simplify the expression before we find it's value when s=-3
positive times negative=negative
so the equation becomes

substituting s=-3 into the equation.

=

=the negatives cancel out leaving

You could turn the fraction into a decimal and then see which is bigger
I agree with you because theta could be acute or obtuse, and if obtuse, negative value.
