Answer:
3. A; 4. C; 5. D; 6. D
Step-by-step explanation:
3. By Pythagorean theorem, x^2=100-64=36, x=6
4. By Pythagorean theorem, x^2=81-36=25, x=5
5. Since the triangle is an isosceles, the other side is 4, so the hypotenuse is 4. (the ratio is 1:1: by Pythagorean theorem)
6. Like Question #5, the ratio is 1:1: since it is an isosceles triangle, the leg is 8.
Answer:
y=-3x
Step-by-step explanation:
Slope intercept form is written as y=mx+b, where:
m= slope
b= y-intercept
We know the slope and y intercept already, so simply plug them in:
y=-3x+0
We can remove the +0 because it is redundant, therefore the final answer is:
y=-3x
Answer: m=1
Step-by-step explanation:
m = (y2 - y1)/(x2 - x1)
Where
y2=12
y1=9
x2=6
x1=3
so plug in your values in the slop formula:
m=(12-9)/(6-3)
=3/3
=1
