B>a 

<span>b=3a-22, b+2a=98, using b from the left in the right: </span>

<span>3a-22+2a=98 </span>

<span>5a-22=98 </span>

<span>5a=120 </span>

<span>a=24, and since b=3a-22, </span>

<span>b=50 </span>

<span>So the smaller number is 24 and the larger number is 50.</span>

X and y
y is smaller

sum of a number and 2 times a smaler is 98
x+2y=98

bigger is 22 less than 3 times smaller
x=-22+3y

sub -22+3y for x in first equation

-22+3y+2y=98
-22+5y=98
add 22 to both sides
5y=120
divide both sides by 5
y=24

sub back
x=-22+3y
x=-22+3(24)
x=-22+72
x=50

the numbers are 24 and 50

I need help pls asap
lilavasa [31]

Answer:

Step-by-step explanation:

first we are told that side and ae and a f are the same

so that means one side of each triangle is the same

next we are told that that the lines coming off of those sides are both right angles. so we know these are both right triangles

and b/c both of those angle are right angles... the sides ab and ac have to also be the same length.. or the angle could not be a right angle

therefore since two sides are the same length then all 3 must be the same lengths

and b/c all three are the same these two triangles are the same .. congruent

For the graphed function f(x) = (4)x − 1 + 2, calculate the average rate of change from x = 1 to x = 2.
xz_007 [3.2K]
For the function
  f(x) = 4^(x-1) +2
the average rate of change on the interval [1, 2] is found by computing
  (f(2) - f(1))/(2 - 1)
  = ((4^1+2) - (4^0+2)/1
  = (6-3)
  = 3
