Answer:
-14.5
Step-by-step explanation:
6.5 * -3 = -14.5
- * + = -
the top question is the second answer and the second question is also the second answer
Answer:
45
Step-by-step explanation:
Plug in the values into the equation
4(12) - 3
48 - 3 = 45
Well u have a basic equation y=a • b^x
a is the initial amount
b is the growth factor
and x is the exponent
the first step is to make a chart with ur two points for example
(0,4) and (2,16)
so ur chart will be
x. | y.
0. | 4
2. | 16
next you find the difference between the x side so 0 to 2 is +2
then find the difference between the y side so 4 to 16 is +12
then put it into a fraction with y over x or y/x so 12/2 then simplified 6/1 or just 6.
6 is the growth factor
and to find a u have to go on the y column and find the first number so
a is 4
x is still x because it's 0 but if it was 2 then it would be x-2 so it can cancel
so the answer would be y=4 • 6^x
Its A, all y-values are less than -3x+5. also consider root by setting -3x+5=0
x=5/3 is positive so its the first one
