Answer:
1.) 90 ways
2.) 15,600 ways
3.) 24 ways
Step-by-step explanation:
1.) Let's say we are given 2 digits not equal to each other...The number of different orderings would be 2*1 = 2, or if we wanted the number of ways to order 2 digits chosen : 10*9 = 90 ways
2.) The number of ways to arrange 3 letters from 26 letters is:
26 Permutes 3 = 26! / (26 -3)! = 26*25*24 = 15,600 ways to choose 3 letters in a certain order
3.) 4 different chores. The number of ways to do them = 4*3*2 *1 = 24 ways
4(4x + 5)
4(4•7+5)
4(28+5)
4(33)
132
1) m∠1 = 360°/8 = 45° . . . . . a regular octagon is 8-way rotationally symmetrical, so each sector is 1/8 of a circle.
2) m∠2 = (180° -45°)/2 = 67.5° . . . . . . the angles of a triangle add to 180°. The base angles of an isosceles triangle are equal.
Answer:
the y intercept is 3 for both functions,
the y intercept is the same
Step-by-step explanation:
y = x+3
is in the form y= mx+b where m is the slope
the slope is 1
the y intercept is 3
graph pick 2 points to find the slope
to get from one point to the next
we go up 1 and to the right 3
m = rise/ run = 1/3
the y intercept is 3
the slopes are not the same, the slope of R > S
the y intercept is 3 for both functions, the y intercept is the same
