Answer:
2/45
Step-by-step explanation:
Total socks:
7 + 8 + 10 + 5 = 30
P(blue) × P(patterned)
8/30 × 5/30
4/15 × 1/6
2/45
Answer:
Step-by-step explanation:
Slope intercept form is , so we have to find a way to substitute the given information into the equation. We have because it gives us the slope. The slope is -1, as the directions state. Now, we substitute it in and solve for b:
- Substitute -1 in for m⇒
- Substitute in the point (-1, -4) in for and respectively to get
- Solve the equation to get b= -5
After getting the y-intercept, you have the full equation!
Answer:
justin = 135 & greg = 150
Step-by-step explanation:
equations:
(justin is 15lbs under greg) j-15=g
(find gregs full weight by doubling bc the problem gave you half) 75*2=150
(plug in gregs wieght to find justins weight) j-15=150 -> j=135
Answer: y= 9x+ 25
Step-by-step explanation:
to calculate the slope, rise/run rise is difference in y-values 25 -(-2) =27
run is difference in x-values 0-(-3) = 3 . 27/3 = 9
b= y-intercept Given: 25
G inverse ( g^-1 (x) ) = x-2 over 2. so, g^-1 (3) = 3-2 over 2 = 1/2
