Answer:
[tex]7^{x}[/tex] or "7 to the power of x"
Step-by-step explanation:
Ok! So an exponential function is a function with a variable as an exponent.
x y
0 1
1 7
2 49
3 343
An example exponential function is [tex]2^{x}[/tex]
Now! Let's look at what number multiplies by each of our "y" values to get the following "y" value. 7!
Now let's see if we can put 7 to the power of x ([tex]7^{x}[/tex]) to get the rest of our table.
[tex]7^{0}[/tex] = 1
[tex]7^{1}[/tex] = 7
[tex]7^{2}[/tex] = 49
[tex]7^{3}[/tex] = 343
Now, we know our exponential function is [tex]7^{x}[/tex]

Write the equation of the line that passes through the points (−3, 5) and (2, -10) in slope-intercept form.
Answer:
[tex]y=-3x-4[/tex]
Step-by-step explanation:
Hi there!
Slope intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)
1) Determine the slope (m)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where the two given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the given points (−3, 5) and (2, -10)
[tex]m=\frac{-10-5}{2-(-3)}\\m=\frac{-10-5}{2+3}\\m=\frac{-15}{5}\\m=-3[/tex]
Therefore, the slope is -3. Plug -3 into [tex]y=mx+b[/tex] as m:
[tex]y=-3x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=-3x+b[/tex]
Plug one of the given points, (−3, 5) or (2, -10) into the equation and isolate b
[tex]5=-3(-3)+b\\5=9+b[/tex]
Subtract 9 from both sides
[tex]5-9=9+b-9\\-4=b[/tex]
Therefore, the y-intercept is -4. Plug -4 into [tex]y=-3x+b[/tex] as b:
[tex]y=-3x-4[/tex]
I hope this helps!

Answer:
245.5 cm²
Step-by-step explanation:
Formula : -
Area of square = side²
Area of square
= 18²
= 324 cm²
Formula : -
Area of circle = πr²
Area of circle
= ( 22 / 7 ) x 5 x 5
= 3.14 x 25
= 78.5 cm²
Area of shaded region
= ( Area of square ) - ( Area of circle )
= 324 - 78.5
= 245.5 cm²

Step-by-step explanation:
Given that,
game 1 game 2
Points 12 18
Shots 14 w
One proportion is : [tex]\dfrac{12}{14}=\dfrac{6}{7}[/tex]
Other proportion is : [tex]\dfrac{18}{w}[/tex]
So,
[tex]\dfrac{6}{7}=\dfrac{18}{w}\\\\w=\dfrac{7\times 18}{6}\\\\w=21[/tex]
So, the value of w is equal to 21.

Based on the table, how much more money would a person with a bachelor's degree earn than a person with an associate's degree over a 30 year career?
A) $16,000
B) $480,000
C) $1,095,000
D) $1,575,000
Answer:
B) $480,000
Step-by-step explanation:
Annual salary of a person with associate's degree
= $36,500
Over a 30 year career the person would earn;
= 30 × 36500
= $10,95,000
Now, annual salary of a person with bachelor's degree = $52,500
Over a course of 30 years he would earn;
= 30 × 52500
= $15,75,000
Difference = $15,75,000 - $10,95,000 = $480,000
So the person with bachelor's degree would earn $480,000 more than a person with associate's degree.
Please Help Jane has 10 cards Jane is going to make a row containing four cards how many unique ways can she ordered the row
it will be 151200 is the anwser
There will be a total of 5040 unique ways to make arrangements of 4 cards out of 10 so option (A) will be correct.
What are permutation and combination?When the order of the arrangements counts, a permutation is a numerical approach that establishes the total number of alternative arrangements in a collection.
The number of alternative configurations in a collection of things when the order of the selection is irrelevant is determined by combination.
Given the 4 cards arrangement out of 10
npr = n! /(n-r)!
Here n = 10 , r = 4
10p4 = 10! /(10-4)!
10p4 = 10 × 9 × 8 × 7 × 6! /6!
10p4 = 5040
So there will be a total of 5040 ways to arrange the cards.

Answer:
Equation: 2x + 1 = 9x - 13
There are two chairs in each row.
Step-by-step explanation:
Looking at the problem, we see that Hue can form two rows of chairs with 1 left over, or 9 rows if she gets 13 more. With that information we can create the equation 2x + 1 = 9x - 13. Now let's solve for x.
2x + 1 = 9x - 13
What we can do first is subtract 9x from both sides. This is done so all of the variables are on one side. Thus that becomes...
2x + 1 - 9x = -13
Now, combine -9x and 2x to get -7x.
-7x + 1 = -13
Now subtract 1 from both sides. This is done so we solve for x directly.
-7x = -13 - 1
Subtract -1 from -13 to get -14.
-7x = -14
Now divide both sides by -7.
x = -14/-7
Divide -14 by -7 to get 2. Remember, dividing two negatives gives you a positive!
x = 2
With that, the equation is solved. There are 2 chairs in each row.
5. Chante was very cold. She wanted to wear her new jacket with the pink
flowers on it. Her mother said that it was negative seven degrees Celsius
but that it was going to be eleven degrees Celsius by afternoon. How many
degrees would the temperature have to rise to reach eleven degrees
Celsius? Convert 11 degrees Celsius to Fahrenheit.
Step-by-step explanation:
To find how many degrees the temperature would have to rise you need to do 11 - (-7) which is equal to 18. So the temperature rose 18 degrees.
To convert Celsius to Fahrenheit you need to do
(C * 9/5) + 32. In this case it would be (11 * 9/5) + 32 which results in 51.8 degrees Fahrenheit.

Answer: <B= 101, <C= 79, <D=101
Step-by-step explanation: all parallelograms have the diagonal angles equal so that is why <c=79. Parallelograms also have all angles equal to 360. so if you add <C, and <A you have 158. then you subtract that from 360 and you get 202. You then need to divide it by to to get the measures of angles B and D which are 101 each.

Part A
Consider the equation of two lines.
Line 1: -3x – 3y = 6.
The slope of the first line is
Line 2: 4x + 4y = 8.
The slope of the second line is
Part B.
What can we infer about the two lines?
PLEASE HELP
Answer:
-1 ; -1 ; the two lines are parallel
Step-by-step explanation:
To find the slope of the two lines, we can proceed in two different ways:
1) the faster is do the division: -a/b where a is the number the multiplies x and b is the number that multiplies y
line 1: m = 3/-3 = -1 line 2: -4/4 = -1
2) the second is to rewrite the two equation in the slope intercept form and find what term multiplies the x
line 1
-3y = 3x+6
-y = x + 2
y = -x -2
m = -1
line 2
x+y = 2
y = -x +2
m = -1
the two lines have the same slope, so they are parallel
