All the points in the doubly-shaded area are in the solution set.
Substitute any value for zero on the equation to find the x and y intercept in order to graph:
10x-3(0)=-15
10x=-15
/10x /10x
x=-1.5
Repeat for y:
10(0)-3y=-15
-3y=-15
/-3 /-3
y=5
Answer:
6) 6
9) 40
10)
11) 13
Step-by-step explanation:
6)A right triangle rule: if 2 legs are equal, the hypotenuse is the length of that leg*
9) Pythagorean Theorem
We know the hypotenuse (41) so we substitute that for c and 9 for b now we need to find a
which gives us 40
10) same with #6 but we do the opposite. SInce we have the hypotenuse, we can divide that by because we know that if 2 legs are equal, the hypotenuse is multiplied by . Multiply the numerator and denominator by because we can't have a square root in the denominator.
11) like #9 we have the a and b but we need to find c
a=5 b=12 c=r
so which gives us 13
