Write a linear function f with the given values.
f(0) = 4,f(5)=19
Answer:
f(x) = 19x/5+4
Step-by-step explanation:
f(0) = 4,f(5)=19
[f(x) - 4]/[x-0] = (19-0)/(5-0)

solve for x
Answer:
121
Step-by-step explanation:
Number of sides = n = 7
Sum of all the interior angles = (n -2)*180 = (7-2) *180
= 5 *180
= 900
x + 125 + 119 +117 +145 + 133 + 140 = 900
x + 779 = 900
x = 900 - 779
x = 121
Answer:
x = 121°
Step-by-step explanation:
The formula to find the sum of interior angles of a polygon is:
180 ( n - 2 )
Here,
n ⇒ number of sides ⇒ 7
First, let us find the sum of the interior angles of the polygon.
180 ( n - 2 )
180 × ( 7 - 2 )
180 × 5
900°.
Accordingly, let us make an expression to find the value of x.
145 + 133 + 140 + 125 + 119 + 117 + x = 900
Let us solve for x now.
779 + x = 900
Subtract 779 from both sides.
x = 900 - 779
x = 121
3) The cost of a movie ticket and a candy bar is $5. The cost of 2 tickets
and a candy bar is $8.75. How much is a candy bar? *
Answer:
$1.25
Step-by-step explanation:
Given data
let the movie ticket be x and the candy bar be y
x+y= 5-------------1
also
2x+y= 8.75--------2
solve 1 and 2
x+y= 5
2x+y= 8.75
from 1
x= 5-y
put this inplace of x in 2
2(5-y)+y=8.75
10-2y+y= 8.75
10-y= 8.75
10-8.75=y
y= 1.25
Hence candy bar is $1.25
Use the Distance Formula to find the distance between each pair of points. Round to the nearest tenth if necessary.
5. P(1, 1), Q(–1, –1)
6. E(1/2,4 1/4),F(5,-1/2)
Given:
The pair of points.
5. P(1, 1), Q(–1, –1)
6. [tex]E\left(\dfrac{1}{2},4\dfrac{1}{4}\right), F\left(5,-\dfrac{1}{2}\right)[/tex]
To find:
The distance between the pair of points.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
5.
The distance between the pair of points P(1, 1) and Q(–1, –1) is:
[tex]PQ=\sqrt{(-1-1)^2+(-1-1)^2}[/tex]
[tex]PQ=\sqrt{(-2)^2+(-2)^2}[/tex]
[tex]PQ=\sqrt{4+4}[/tex]
[tex]PQ=\sqrt{8}[/tex]
[tex]PQ=2\sqrt{2}[/tex]
Therefore, the distance between P and Q is [tex]2\sqrt{2}[/tex].
6.
The distance between the pair of point [tex]E\left(\dfrac{1}{2},4\dfrac{1}{4}\right), F\left(5,-\dfrac{1}{2}\right)[/tex] is:
[tex]EF=\sqrt{\left(5-\dfrac{1}{2}\right)^2+\left(-\dfrac{1}{2}-4\dfrac{1}{4}\right)^2}[/tex]
[tex]EF=\sqrt{\left(\dfrac{10-1}{2}\right)^2+\left(-\dfrac{1}{2}-\dfrac{17}{4}\right)^2}[/tex]
[tex]EF=\sqrt{\left(\dfrac{9}{2}\right)^2+\left(\dfrac{-2-17}{4}\right)^2}[/tex]
[tex]EF=\sqrt{\dfrac{81}{4}+\left(\dfrac{-19}{4}\right)^2}[/tex]
On further simplification, we get
[tex]EF=\sqrt{\dfrac{81}{4}+\dfrac{361}{16}}[/tex]
[tex]EF=\sqrt{\dfrac{324+361}{16}}[/tex]
[tex]EF=\sqrt{\dfrac{685}{16}}[/tex]
[tex]EF=\sqrt{42.8125 }[/tex]
[tex]EF\approx 6.5[/tex]
Therefore, the distance between E and F is 6.5 units.

On a middle school basketball court, there is a large circle painted on the
floor. The diameter of the circle is 12 feet. What is the area of the circle?
Jse 3.14 for a
Answer:
113.04 feet²
Step-by-step explanation:
Use the circle area formula, A = [tex]\pi[/tex]r²
Sine the diameter is 12 feet, the radius is 6 feet
Plug in 6 as r into the formula, and 3.14 as pi, then solve:
A = [tex]\pi[/tex]r²
A = (3.14)(6²)
A = (3.14)(36)
A = 113.04
So, the area of the circle is approximately 113.04 feet²
Answer:
113.04 feet²
Step-by-step explanation:

Work out the area of this circle. Take pi to be 3.142 and give your answer to 1 decimal place
Step-by-step explanation:
I think you have forgotten to attach the question.
Anyways....
In order to find the area of a circle use the formula:
π[tex]r^{2}[/tex] Where r is the radius
For example the radius is 3cm. The area of the circle will be:
π × [tex]3^{2}[/tex]
Since you have taken pi as 3.142...
3.142 × [tex]3^{2}[/tex]
3.142 × 9
= 28.278
In order to find the answer to 1 decimal place, check the number next to the number right after the decimal. Is it a number greater than or equal to 5? then add +1 to the number.
= 28.3 [tex]cm^{2}[/tex]

What is the slope of a vertical line?
What is the slope of a horizontal line?
Answer:
The slope of a vertical line is undefined. The slope of a horizontal line is 0
Step-by-step explanation:
Slope is rise/run
and the rise of a horizontal line is zero since it neither increases nor decreases; therefore, the slope is zero. while a vertical line has undefined slope since it does not run horizontally because division by zero is an undefined operation.

Answer:
x = 65
Step-by-step explanation:
Triangle interior angle sum is 180 degrees.
2x + 25 + 25 = 180
2x = 130
x = 65
Answer:
65
Step-by-step explanation:
OK so we know that the bottom line shows a 180 degrees angle
so 180-25+25 = 180-50 = 130
Now divide 130 by 2 and you should get 65.

Ali and Jake went on a cross-country
trip. They took a train part of the way,
and took a bus the rest of the way. They
traveled a total of 1100 kilometers,
riding on the train 350 more kilometers
than on the bus.
Let x = kilometers traveled by bus. Let
y = kilometers traveled by train.
Answer:
Let x = Kilometers by bus
then x + (x + 350) = 1100
2x = 750
x = 375 by bus
x - 350 + x = 1100
2x = 1450
x = 725 by train
