The domain of this function is (-12, -6, 3, 15).
y =-2/3x +7
Complete the table based on the given domain.
(Table in Picture)
(PLEASE HELPP)))
Answer:
Step-by-step explanation:
1) y = -2/3* -6 + 7 =
y= 11
2) 5 = -2/3 x + 7
-2/3 x = -2
x = 3
3) y = -2/3 * 15 + 7
y = -3
4) 15 = -2/3x + 7
2/3x = -8
x = -12
which sum or difference is modeled by the algebraic tiles?
Answer:
C
Step-by-step explanation:
Solve the system of equations given below. (Please--help..)
Step-by-step explanation:
x+2y=-4
2x+3y=1
The difference between this two equations is x+y so:
x+y
=1-(-4)
=1+4
=5
I'm not sure what the question is asking to find, but I have already helped you find the value of x+y, good luck with the rest I guess :))

A candle is 6 tall after burning for one hour. After 3 h, it is 5. 5 tall. Write a linear equation to model the hh () of the candle after burning () h.
Answer:
h(t) = -0.25t + 6.25
Step-by-step explanation:
Given that :
Height of candle after burning for 1 hour = 6
Height of candle after burning for 3 hours = 5.5
The linear model to show the height ight of candle after burning for h hours :
The height change per hour of burn ; this is the slope ;
Change in height / Change in time ;
Time = 1 hour ; height = 6
Time = 3 hours ; height = 5.5
Slope = (5.5 - 6) / (3 - 1) = - 0.5 / 2 = - 0.25
This means candle height decreases ; - 0.25 ft per hour :
Based on the linear, slope, intercept equation ;
y = mx + c
Candle height, h
h(t) = mt + c
c = intercept, we can obtain this thus ;
Using the height at 1 hour and slope;
After an hour burn :
6 = - 0.25t + c
t = 1
6 = - 0.25(1) + c
6 = - 0.25+c
6+0.25 =, c
c = 6.25
Hence ; to calculate height, h after burn time &
h(t) = -0.25t + 6.25

Find (-4) for f(x) = 9(3)^x
A. -108
B. 1/3
C. -729
D. 1/9
Answer:
D
Step-by-step explanation:
9(3)^-4
3^2 × (3^-4)
in algebraic expression a^n × a^m = a^n+m
3^2+(-4)
3^-2
but 3^-2 = 1/3²
1/3²= 1/9
The option (4) is correct i.e., when [tex]x=-4[/tex] then
[tex]f(x) = 9(3)^x\\\\f(x)=\frac{1}{9}[/tex]
What is the equation?
The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Here given equation is
[tex]f(x)=9(3)^x\\\\\\x=-4\\\\\\f(-4)=9(3)^{-4}\\\\f(-4)=\frac{9}{(3)^4}\\\\f(-4)=\frac{9}{81}\\\\f(-4)=\frac{1}{9}[/tex]
Hence, the option (4) is correct i.e., when [tex]x=-4[/tex] then
[tex]f(x) = 9(3)^x\\\\f(x)=\frac{1}{9}[/tex]

Find the slope of the line passing through the points (-6, 4) and (-6, -9).
Answer:
There is no slope.
Step-by-step explanation:
Following the formula for slope,
y^2 - y^1
-------------
x^2 - x^1
when inputting our values, we get -13/0. We cannot divide by 0 and because the 0 is in the denominator, it means that there is no slope.
