Linear function f is shown in the graph. Write the slope-intercept form of the equation representing this function.
The equation representing the function f(x) -
y = 4x - 8
We have a linear function f(x) as shown in the graph.
We have to determine the slope-intercept form of the equation representing this function.
What is the Slope - intercept form of the equation of a straight line ?The Slope - intercept form of the equation of a straight line is as follows -
y = mx + c
where -
m - slope of line
c - intercept of line on y - axis.
According to the question, we have -
c = - 8 = intercept of line on y - axes.
Intercepting coordinates on y - axes = (0, -8).
Intercepting coordinates on x - axes = (2, 0).
Slope = m = [tex]\frac{-8-0}{-2 -0}[/tex] = 4
Therefore, the equation representing the function f(x) -
y = 4x - 8.

Choose 1 answer:
4 hundreds plus 1 ten
2 hundreds plus 12 tens
2 hundreds plus 11 tens
Answer:
2 Hundreds plus 12 Tens
Step-by-step explanation:
Since 2 hundred equals 200, and 12 tens equals 120, the equation goes 200 + 120, which equals 320.
Evaluate the expression for a = 3, b =12, and c = 4.

Answer:
The probability of selecting a vowel is 5/26
Step-by-step explanation:
The probability of selecting a vowel
= number of vowels/total number of alphabets
The vowels are a,e,i,o,u = 5
Number of alphabets = 26
The probability is 5/26
Daniela, Kieu, and Cameron decide to go to the movies one hot summer afternoon. The theater is having a summer special called Three Go Free. They will get free movie tickets if they each buy a large popcorn and a large soft drink. They take the deal and spend a total of $22.50 on large popcorns and soft drinks. The next week, they go back again, only this time, they each pay $8 for a ticket, they each get a large soft drink, but they share one large bucket of popcorn. This return trip costs them a total of$37.50. Use systems of equations to find the price of a large soft drink and the price of a large bucket of popcorn!
Answer:
Price of a large soft drink = $3
Price of large bucket of popcorn = $4.5
Step-by-step explanation:
Let the cost of one large popcorn = $P
And the cost of one large soft drink = $S
If Daniela, Kieu and Cameron avail the deal of Three Go Free,
3P + 3S = 22.50
P + S = 7.5 -----(1)
Next time they each pay $8 for a ticket, they each get a large soft drink but they share one large bucket of popcorn.
This trip cost them = $37.50
Cost of 3 tickets + Cost of 3 large soft drinks + Cost of one large bucket of popcorn = 37.50
(3 × 8) + (3 × S) + P = 37.5
24 + 3S + P = 37.5
3S + P = 13.5 -----(2)
By subtracting equation (1) from equation (2),
(3S + P) - (P + S) = 13.5 - 7.5
2S = 6
S = $3
From equation (1),
P + 3 = 7.5
P = $4.5
Therefore, price of a large soft drink is $3 and a large bucket of popcorn is $4.5

The recursive formula is [tex]a_n\\[/tex] = 6n - 4.
What is Recursive formula?Any term of a series can be defined by its preceding term in a recursive formula (s).
A recursive formula consists of two parts: a declaration of the first term and a declaration of the formula connecting the succeeding terms.
For example: The recursive formula of an arithmetic sequence is,
an = an-1 + d.
Given:
2, 8, 14, 20
The above data shows Arithmetic Progression series.
a = 2
d = 8-2
d= 6
So, using Arithmetic Progression
[tex]a_n[/tex] = a+ (n- 1) d
[tex]a_n\\[/tex] = 2+ (n- 1)6
[tex]a_n\\[/tex] = 2+ 6n - 6
[tex]a_n\\[/tex] = 6n - 4
Hence, the recursive formula is [tex]a_n\\[/tex] = 6n - 4.

Lashawn solved the equation below to the determine the solution 3x-8=-x+4(x-2)
Answer:
all real numbers
Step-by-step explanation:
3x-8 = -x + 4(x-2)
distributive property:
3x - 8 = -x + 4x-8
Combine like terms:
(add 3x to both sides)
-8 = -8
That means that x can be any number, because in the end, x will be canceled out from the equation.

Triangle JKL is shown below. Find the value of x.
Answer:
x=9
Step-by-step explanation:
every angle of a triangle added together equals 180. ill just show my work bc its hard to explain:
7x+2 + 4x+7 + 8x = 19x+9
19x+9 = 180
-9 -9
19x = 171 (now divide by 19)
x=9
i need help please what is the x
Answer:
x=4
Step-by-step explanation:
well you know that the square is 90 degrees so you set it up as 90=21x+6. Then you subtract 6 from both sides and it gets you 84=21x. Then divide 21 on both sides. So the answer is x=4
Two angles are supplementary. One measures 3x-2 and the other measures 2x+7 Find the value of x and the measure of the smaller angle.
Sum of two angles that are supplementary = 180°
Then :-
[tex]3x - 2 + 2x+ 7 = 180[/tex]
[tex]5x + 5 = 180[/tex]
[tex]5x = 180 - 5[/tex]
[tex]5x = 180 - 5[/tex]
[tex]5x = 175[/tex]
[tex]x = \frac{175}{5} [/tex]
[tex]x = 35[/tex]
Which means :-
The measure of the larger angle :-
= 35 × 3 - 2
= 105 - 2
= 103°
The measure of the smaller angle :-
= 2 × 35 + 7
= 70 + 7
= 77°Therefore , the value of x = 35 and the measure of the smaller angle = 77° .
Ella babysits 3 hours each for 4 days on the fifth one she babysits for 6 hours .write an equation that shows how many hours Ella babysits for altogether ?
Find the value of x.
Answer:
x=55
Step-by-step explanation:
you have to add the three angles to get 180 first. 180- 21-34=125.
then take the missing angle inside the triangle (125) and subtract by 180.
180-125=55
Answer:
x = 55
Step-by-step explanation:
We know that triangles add up to 180 degrees, so let's start with that. Keep in mind that "y" will be the third degree of the triangle.
21+34+y = 180
55+y = 180
y = 125
Okay, now we know that the third degree is 125. Also, the line that 125 and x are on is a straight line. All straight lines are 180 degrees. Subtract 180 and 125 to get your answer.
180-125 = 55
So your final answer will be x=55, hope this helped!
