So we know
[tex]\\ \rm\rightarrowtail y=ab^x[/tex]
Put what's given
[tex]\\ \rm\rightarrowtail -3=ab^0[/tex]
[tex]\\ \rm\rightarrowtail -3=a[/tex]
Now put back
[tex]\\ \rm\rightarrowtail y=-3b^x[/tex]
Range of all y values less than 0turn b to Euler's number thenAs we know that e^x has range (0,oo) when multiplied with any negative number i.e here -3 it yields y less than 0[tex]\\ \rm\rightarrowtail y=-3e^x[/tex]

Answer:
General form of an exponential function: [tex]y=ab^x[/tex]
where:
[tex]a[/tex] is the y-intercept (or initial value)[tex]b[/tex] is the base (or growth factor)[tex]x[/tex] is the independent variableIf [tex]b > 1[/tex] then it is an increasing function
If [tex]0 < b < 1[/tex] then it is a decreasing function
Also [tex]b\neq 1[/tex]
Given:
y-intercept = (0, -3)[tex]\implies y=(-3)b^x[/tex]
If we want the function to be decreasing, then as [tex]a[/tex] is negative, we need [tex]b > 1[/tex] to make the overall function decreasing.
Let [tex]b=2[/tex] :
[tex]\implies y=(-3)2^x[/tex]
If we want the function to be increasing, then as [tex]a[/tex] is negative, we need [tex]0 < b < 1[/tex] to make the overall function increasing.
Let [tex]b=\dfrac12[/tex] :
[tex]\implies y=-3\left(\dfrac12\right)^x[/tex]
However, it doesn't matter whether the function is increasing or decreasing as the range of both of the above given functions is < 0 as [tex]a[/tex] is negative and [tex]b[/tex] is positive.

Answer:
this is how!!!
Step-by-step explanation:
so since it says “unit price” (also says dollar per bananas) all you have to do is make a variable and substitue
So:
Let number of bananas be “ b “
0.50b
0.5(4)
2
2 dollars
It the same for the rest except the last two
Since you dont know the number of bananas, let b be unknown, but may it equal to the cost given. For example:
10 = 0.5b
Since you dont know b
To solve for b, you have to make b be all by itself (like me when my cousin is sleeping on the other side of the world ;’) )
To do that you have to divide 0.5 to both sides
10 / 0.5 = 0.5b / 0.5
This will remove 0.5 from the right side and isolate b
Since b and 0.5 are being multiplied you can factor 0.5 out from the right side
10 / 0.5 = b
Now simplify
B = 20 bananas
Which situation can be represented by the inequality x < 56? A) Tina's dog weighed 56 pounds two months ago. He gained weight and weighs x pounds now. B) Tina has x dollars. She has more than enough money to buy a camera that costs $56. C) Tina walks for 56 minutes. She walks for the same amount of time as her sister, who walks for x minutes. D) Tina's height is x inches. She is shorter than her brother, whose height is 56 inches.
Answers
Given:
The inequality is [tex]x<56[/tex].
To find:
The correct situation for the given inequality.
Solution:
Tina's dog weighed 56 pounds two months ago. He gained weight and weighs x pounds now. It means, weighs x pounds is more than 56 pounds.
[tex]x>56[/tex]
So, option A is incorrect.
Tina has x dollars. She has more than enough money to buy a camera that costs $56. It means, amount $x is more than required amount $56.
[tex]x>56[/tex]
So, option B is incorrect.
Tina walks for 56 minutes. She walks for the same amount of time as her sister, who walks for x minutes. It means, x is equal to 56.
[tex]x=56[/tex]
So, option C is incorrect.
Tina's height is x inches. She is shorter than her brother, whose height is 56 inches. It means, Tina's height is x inches is less than her brother's height, i.e., 56 inches.
[tex]x<56[/tex]
Therefore, the correct option is D.

Step-by-step explanation:
Question 8: Ramiro is correct because the triangles are similar by AA (the measure of angle C in triangle ABC is 180-62-39=79 degrees). Julie is wrong because you would need at least 1 pair of corresponding congruent sides to prove the triangles congruent (angles alone are not sufficient)
The question with the angle diagram:
Since angles A and B are supplementary (since they form a linear pair), their measures add to 180 degrees. Hence, the measure of angle B is 180-140=40 degrees.
The measure of angle E can be found by the same logic, and has a measure of 50 degrees.
Since the sum of the measures of the angles of a triangle is 180 degrees, the measure of angle C is 180-40-50=90 degrees.
Hence, since angles C and D are supplementary, angle D has a measure of 90 degrees.

GEOMETRY HELP!!!!!!!!
Why is he wrong?
Answers
Answer:
He is wrong since reflecting the image across the x-axis means reflecting it on the axis that is horizontal and reflecting it over the y-axis means reflecting it on the y-axis which is verticle.
Answer:No, it would not be the same if you reflect it from the X axis.
Step-by-step explanation:
because the the shape is not "on" the X axis. When you reflect the shape across the X axis, then you will not really get a shape. It's easier if you imagine you put a mirror on the x axis and looked at it. Malik would have to shift the whole shape down so that the current points (3,1) and (-3,1) would change to (3,0) and (-3,0) Also shifting down the other two points too. Reflecting it is like if you had the shape in paper and you folded it in half. If it matches perfectly, then you know that you have a match and that it is reflecting. If it doesn't fold perfectly, then it doesn't reflect. So if you folded the shape from the X axis, you wouldn't get a perfect match so he is wrong. Does it help?

Answers
The total amount of fertilizer needed for the rectangular garden is 0.315 kg.
What is the total amount of fertilizer needed?The first step is to determine the area of the garden.
Area of the garden = length x width
=1.2 x 3.5 = 4.2
The second step is to multiply 0.075 by 4.2
0.075 x 4.2 = 0.315 kg

An international calling plan charges a rate per minute plus a connection fee. You can make a phone call from France to the United States for $0.22 per minute plus a $0.99 connection fee. Write a linear equation that could be used to represent the cost of an x minute phone call.
Answers
Answer:
y=0.22x+0.99
Step-by-step explanation:
Notice that in this problem they are giving us a rate $0.22 per minute. This means that whenever we multiply that rate by the number of minutes used, we will get the total amount of money spent. In this case, since we don't know the amount of minutes (variable) we will call them x, so the first part of the equation should be:
0.22x
the connection fee is $0.99, which means that no matter the time you take talking by the phone, you will be charged a constant value of $0.99, so we can add that to the previous value we got:
0.22x+0.99
and for the equation to be complete, we can set variable y= to the total cost of the call, so the whole equation would be:
y=0.22x+0.99

This means that if i wanted 2 cups of cranberry juice, i also need double the amount of orange juice, which would be 8 cups.
In this way we can say the ratio of orange juice to cranberry juice would be 4:1.
This is the same as saying for every 1 cup cranberry juice, we need 4 cups orange juice . This is written as 1:4

We are looking for the time the helicopter and the plane will be the same distance from Burbank after 10 AM.We are given the two equations for the distance that the helicopter and the plane are away, in miles.It also says that R is the variable for time.Using this information, we need to solve for the time with broth equations, so we would set both up to be equal to each other, since they will be the same distance away from each other.It would look like this: -150r + 260 = -270r + 440.Add 150r to both sides.260 = -10r + 440.Add -10r to both sides.Now we have 10r + 260 = 440Subtract 260 from both sides.10r = 180Divide each side by 10 to isolate the R.R = 18.It would be 18 hours after 10 AM.If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers.
