You divide $47.50 by 5 and you'll get the answer which is $9.5
Step-by-step explanation:
C + 1 = 2(L-1)
C +1= 2L -2
C- 2L = -3 ......(eq.1)
L+1 = C-1
C- L = 2 .....(eq.2)
by elimination :
C - 2L = -3
C - L = 2
________-
- L = -5
L = 5
C = 2+5 = 7
so, Leo has 5 cars and Charlie has 7 cars
So your equation is currently in point-slope form; however, to figure out the slope and y-intercept, you'd be better off in slope-intercept form: y = mx + b
while in point-slope form, y - y1 = m(x - x1), you can definitely see the slope as -5, you can't see the y-intercept as easily. x-intercepts are actually the solutions/zeros of a function, and it was included in the answer choices to confuse you.
you're correct about -5 being a decreasing slope. but to figure out the y-intercept, you need to convert to slope-intercept form.
y - 4 = -5(x + 1) ... distribute the -5
y - 4 = -5x - 5 ... add 4
y = -5x - 1
and in the form of y = mx + b, where m is the slope and b is the y-intercept, you can see that you have a decreasing slope of -5 and a y-intercept of -1. your correct answer is A. choices C and D were thrown in to distract you and make you think that the -5(x + 1) was somehow related to discovering the x-intercept.
Answer:
The probability that the 2nd Heads occurred at the 4th toss is 5.99%.
Step-by-step explanation:
Given that there were 4 Heads in the first 7 tosses, to find the probability that the 2nd Heads occurred at the 4th toss the following calculation must be performed:
7 - 4 = 3
4/7 x 3/7 x 3/7 x 4/7 = X
0.571 x 0.428 x 0.428 x 0.571 = X
0.0599 = X
Therefore, the probability that the 2nd Heads occurred at the 4th toss is 5.99%.
