Answer:
okay im sorry but i can only help with the first page so im going to use the first equation as an example. when it tells you what x equals in this case four you put it in place of the variable and put it all together and see if those two numbers egual the amount given. so here it written out:
x +11=15 x= 4
4+ 11 + 15.
in this case yes the given numbers equal the amount.
really hope this helped you!
Step-by-step explanation:
The price of gasoline in this week is 1.05g. Option C
Step-by-step explanation:
Given,
The price of a gallon of gasoline = g in last week.
The price of gasoline increased by 5% this week.
To find the price of gasoline this week.
Formula
If an original price of an object a increased by b% the final price will be = a×
So,
The price of gasoline in this week = g×1.05 = 1.05g
[ Please note: Here option C and E have same value. So, both are correct].
Point F; in a function, you need to pass the vertical line test. In other words, if you can't have two points with the same x-value. Every input must have one output. An input can't have multiple outputs. Hope that helped! If you need more help, ask; I know my explanation sucked. :P
Answer:
(-8, -2)
Step-by-step explanation:
Subtract 2 from -6, so -6 -2 which gives -8.
Subtract 3 from 1 so, 3-1 = -2.
The required exponential function that contains the points (3,24) and (4,48) is y = 3(2)^x
<h3>Exponential functions</h3>
The standard exponential function is expresses as y = ab^x
Given the coordinate points (3,24) and (4,48), the equivalent equations are:
24 = ab^3 ......... 1
48 = ab^4
Take the ratios
48/24 = b^4/b^3
2 = b
Substitute b = 2 into equation 1
24 = a(2)^3
8a = 24
a = 3
Hence the required exponential function that contains the points (3,24) and (4,48) is y = 3(2)^x
