Equal too 4 wholes that is my answer
Answer:
y = - 3x + 11
Step-by-step explanation:
the altitude is a line from the vertex A drawn perpendicular to the opposite side BC
calculate the slope of BC using the slope formula
m = 
with (x₁, y₁ ) = B (- 7, 3 ) and (x₂, y₂ ) = C (- 1, 5 )
=
=
=
= 
given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= - 3
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept ) , then
y = - 3x + c ← is the partial equation
to find c substitute A (4, - 1 ) into the partial equation
- 1 = - 12 + c ⇒ c = - 1 + 12 = 11
y = - 3x + 11 ← equation of altitude from A
I would love to help you with this question just send all of the possible answer choices such A,B,C,D answers.
In math, IS represents = OF represents multiply
1. So for the first problem is saying 24% * 80 24% is the same as .24 so .24*80=19.2
2. For this one the problem is saying 15=30%*x So for this we need to find x. So we divide both sides by .3 and get x = 50
3. You do the same thing as in 2. Im not gonna do all ur homework so you can do this one.
Hope that helps :)<span />
