Answer:
slope = -1
y intercept (0,-2)
Step-by-step explanation:
We can use the two points to find the slope
(-4,2) and (1,-3)
m = ( y2-y1)/(x2-x1)
= (-3 -2)/(1 - -4)
= -5 /(1+4)
= -5/5
- 1
The y intercept is where it crosses the y axis
y intercept is (0,-2)
Answer:
Angle A = 53
Step-by-step explanation:
All triangles add up to 180 so...
Lets use x to describe angle A
100+27+x=180
127+x=180
x=53
I'm confused what its asking about b and c but hope this helps a bit :)
Answer:
z<8
Step-by-step explanation:
First: write down the equation : 6z<48
Second: divide both sides with 6 (since its the only number that can be divided for both sides)
Third: then you'll get z<8

You can exploit the difference-of-squares identity,
<em>a</em>² - <em>b</em>² = (<em>a</em> - <em>b</em>) (<em>a</em> + <em>b</em>)
Then
101.5² - 100.5² = (101.5 - 100.5) * (101.5 + 100.5)
101.5² - 100.5² = 1 * 202
101.5² - 100.5² = 202
