Answer:
Use the appropriate entry method for piecewise functions for the graphing calculator of interest.
Step-by-step explanation:
For Desmos, the entry looks like ...
f(x) = {x ≤ 2: -2x-1,-x+4}
_____
For a TI-84 calculator, the entry may look like ...
Y₁ = (-2X–1)(X≤2) + (-X+4)(X>2)
The symbols ≤ and > come from the TEST menu, which is the (2nd) shift of the MATH key.
Note that the function is the sum of the pieces, each piece multiplied by a test. For something like 0≤x<2, the multiplier would be a pair of tests:
... (0≤X)(X<2)
Answer:
94 for the first one and 130 for the second
Step-by-step explanation:
Since A=6 and B=4
For the first one
13(6)+ 4(4)
78+16=94
For the second one
(6+4)*13
(10)*13= 130
Answer:
1.5 times.
Step-by-step explanation:
6.75 / 4.5 = 1.5.

+516 +516
log3x=518
x=(10^518)/3
the answer seems a bit crazy, you probably typed something wrong</span>
Answer:
Step-by-step explanation:
Remark
You have to guess what the question is. I'm assuming that it is either the black triangle to the blue one or the blue one to the black one. Be careful when you post a question to see if you have included a question.
Answer
<em>Ratio of blue to black</em>
The distance of the left most point of the blue triangle to the y axis is 3. The same point on the black one is 1
blue/black = 3/1
<em>Ratio of black to blue</em>
ratio of the black triangle to the blue one is 1/3
The answer will depend on the question. Notice that the two answers are reciprocals.
