Answer: Graph A & B
Step-by-step explanation:
Both A & B have x values that stretch from 1-6. The others are different
Answer:
Step-by-step explanation:
Triangle ABC is a right angle triangle that is made up of 2 right angle triangle.
To determine y, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
15² = y² + 12²
225 = y² + 144
y² = 225 - 144 = 81
y = √81 = 9
To determine z,
20² = z² + 12²
400 = z² + 144
z² = 400 - 144 = 256
z = √256 = 16
Mutiply first equation by -1 and add to 2nd
-y=3x-6
<u>y=x^2-4 +</u>
0=x^2+3x-10
factor like any equation
what 2 numbers multiply to -10 and add to 3
-2 and 5
0=(x-2)(x+5)
set to zero
x-2=0
x=2
x+5=0
x=-5
solve for y in each case
for x=2
y=2^2-4
y=4-4
y=0
(2,0) is a point
for x=-5
y=(-5)^2-4
y=25-4
y=21
(-5,21) is another
the solutions are
(2,0) and
(-5,21)
