Answer:
c
Step-by-step explanation:
consider points (0,2) and (-4,0)
slope=(0-2)/(-4-0)=-2/-4=1/2
y-intercept=2
y=mx+c
y=1/2 x+2
Answer:
yes
Step-by-step explanation:
they are both triangles
Answer:
<em>x = 12</em>
Solve for x:
<em>Using Pythagorean Theorem </em>
a^2 + b^2 = c^2
a = 9
c = 15
b = x
9^2 + x^2 = 15^2
81 + x^2 = 225
x^2 = 144 | sqrt
x = 12
For problems like this we can use algebra to help us, the farenheight 6 hours ago was:
(2xt)-6=-20
We have to balance the sides out, first we minus 6
2xt=-26
Now we can divide by 2
t=-13
We now know the temperature 6 hours ago was -13
