The answer is C) y=14(0.9)ˣ and it's an exponential function
PROOF
Give to x the respective values of x & calculate y, using y = 14(0.9)ˣ
x | y
---------|---------
0 | 14(0.9)⁰ = 14
1 | 14(0.9)¹ = 12.6
2 | 14(0.9)² = 11.34
3 | 14(0.9)³ = 10.206
4 | 14(09)⁴ = 9.1845
Answer:
3 tens
Step-by-step explanation:
4 tens and 5 ones is 45
so 45 minus 15 is 30
so 3 tens
An algebraic expression is, obviously, an expression with a variable.
"A number" would represent a variable, which, in this case, we'll use y.
So, 15 decreased by twice x.
15 - y x 2 =

Answer <u>(assuming it can be in slope-intercept form): </u>
y = x - 5
Step-by-step explanation:
1) First, find the slope of the equation. Use the slope formula, 
, and substitute the x and y values of the given points into it. Then, solve:
2) Now that we know the slope and at least one point the line crosses through, we can write an equation of the line in point-slope form, or 
. Substitute 
, 
, and 
for real values.
Since represents the slope, substitute 1 for it. Since and represent the x and y values of a point the line intersects, use any one of the given points (either one is fine, either way the equation will represent the same line) and substitute its x and y values into the equation. (I chose the point (6, 1), as seen below.) Finally, isolate y to put the equation in slope-intercept form.
