Answer:
[tex]2(3) {}^{x} [/tex]
Step-by-step explanation:
[tex]y = ab {}^{x} [/tex]
We know that when x=1, y=6
[tex]6 = a {b}^{1} [/tex]
x=2, y=18
[tex]18 = a {b}^{2} [/tex]
Notice that if we divide
[tex] \frac{ {ab}^{2} }{ab} = b[/tex]
So if we divide 18 and 6, that will give us our common ratio.
[tex] \frac{18}{6} = 3[/tex]
So our common ratio is 3.
So know we have
[tex]a(3) {}^{x} [/tex]
Plug in one of the points to find a.
[tex]6 = a(3)[/tex]
[tex]a = 2[/tex]
So the equation. we have
[tex]2 \times ({3}^{x} )[/tex]

7. A card is randomly drawn from a standard deck of shuffled cards. What are the ODDS that the
card drawn is a Letter card?
A. 12.5%
B. 75%
C. 25%
D. 44%
There are 16 total "letter cards" (1 ace and 3 face cards per suit), so the probability of drawing a letter card is 16/52 = 4/13.
There are 52 - 16 = 36 non-letter cards, with probability 36/52 = 9/13 of being drawn.
Then the odds of drawing a letter card is the ratio of these probabilities,
(4/13) / (9/13) = 4/9 ≈ 44%

Step-by-step explanation:
Write these values in order, starting with the smallest.
0.15
1/10
12%
1/20
Rewrite them all as a decimal to compare them:
0.15
1/10 = 0.10
12% = 0.12
1/20 = 0.20
Now write them in order : 1/10, 12%, 0.15, 1/20
How many solutions does the system of equations below have?
y = 3x + 4
y+ 6 = 3x
O A. Exactly 1 solution
O B. More than 1 solution
O C. At least 1 solution
O D. No solution
Answer:
No solution
Step-by-step explanation:
Let's solve your system by substitution.
y=3x+4;y+6=3x
Step: Solvey=3x+4for y:
y=3x+4
Step: Substitute3x+4foryiny+6=3x:
y+6=3x
3x+4+6=3x
3x+10=3x(Simplify both sides of the equation)
3x+10+−3x=3x+−3x(Add -3x to both sides)
10=0
10+−10=0+−10(Add -10 to both sides)
0=−10

In Mr. Kagame's Algebra 1 class, 7 students took the Unit 7 test. The class average was 78% (rounded). Six students' scores are known:HELPPP
The score of the seventh student will be given by:
[tex]x = 546 - a_1 - a_2 - a_3 - a_4 - a_5 - a_6[/tex]
What is the score of the last student?
So you know the scores of 6 of the students, let's define these as:
a₁, a₂, a₃, a₄, a₅, a₆.
And let's define x as the score of the 7th student.
We know that the average of the scores is 78% (rounded).
Then we can estimate the value of x using the average equation:
[tex]\frac{a_1 + a_2 + a_3 + a_4 + a_5 + a_6 + x}{7} = 78[/tex]
Now you can solve that for x, to get:
[tex]x = 78*7 - a_1 - a_2 - a_3 - a_4 - a_5 - a_6\\\\x = 546 - a_1 - a_2 - a_3 - a_4 - a_5 - a_6[/tex]
That is the equation to get the score of the seventh student as a function of the six known scores.

Suppose the distributor charges the artist a $50.00 cost for distribution, and the streaming services pay $ 5.00 per unit. (Note: One unit = one thousand streams) Model the profit for the total number of streams by answering the questions below:
1. Use the cost for distribution to build the y-intercept. What is the y-intercept?
Hint: the y-intercept is a point on the y axis, so the answer should be an ordered pair
(x,y). Keep in mind that money is being spent, and therefore must be deducted from the profit. If the y-intercept is incorrect, all related numbers will be incorrect.)
2. Use the payment per unit to build the slope. What is the slope?
Equation in slope intercept form
y=mx+by=5x+50Slope:-m=5
Y intercept=b=50
The y-intercept of the function is (0, 50) and the slope of the function is 5
How to calculate the slope and y-intercept of a function?Slope is defined as the rate of change of function. Given the following parameters
Fixed price = $50
If the streaming services pay $ 5.00 per unit, then the rate of change is $5
The required profit for the total number of streams is given as:
P(x) = 50 + 5x
1) The y-intercept is the point where the value of x is zero
P(x) = 50 + 5x
P(0) = 50 + 5(0)
P(0) = 50
Hence the y-intercept of the function is (0, 50)
For the slope
mx = 5x
m = 5
Hence the slope of the function is 5

What single percentage change is equivalent to a 9% increase followed by a 17% increase?
Answer:
27.53%
Step-by-step explanation:
Initial number = 100
9% increase
100*1.09= 109
17% increase
109*1.17= 127.53
The difference with the initial number is:
127.53 - 100 = 27.53
27.53/100*100% = 27.53%
This is the single percentage change

Find all real solutions Tan pi/3 x-3=0
Step-by-step explanation:
If the question is like this,
[tex] \tan( \frac{\pi}{3}x - 3 ) = 0[/tex]
We take the arc tan of both sides.
[tex] \tan( - 1) ( \tan( \frac{\pi}{3}x - 3 ) = \tan {}^{ - 1} ( {}^{ }0 ) [/tex]
[tex] \frac{\pi}{3} x - 3 = 0[/tex]
[tex] \frac{\pi}{3} x = 3[/tex]
[tex] = \frac{9}{\pi} [/tex]
Since the period of a tan function, is pi, we divide pi by pi/3 since pi/3is the coeffeicent of the x variable
[tex] \frac{\pi}{ \frac{\pi}{3} } = 3[/tex]
So the answer is
[tex] \frac{9}{\pi} + 3n[/tex]
If this the question,
[tex] \tan( \frac{\pi}{3} x) = 3[/tex]
[tex] \frac{\pi}{3} x = 1.249[/tex]
[tex]x = \frac{3.747}{\pi} [/tex]
The period is once again 3 so we have
[tex] \frac{3.747}{\pi} + 3n[/tex]
where n is a interger.

4b) Find the area of the following shapes.
Answer:
180
Step-by-step explanation:
To find the area of the rectangle, multiply 15 by 9
15 x 9 = 135
To find the area of the triangle, multiply 15 by 6, then divide by 2
15 x 6 = 90
90/2 = 45
Now add these two numbers to get the total area.
135 + 45 = 180
