Alexa is planning to drive across the United States in her car. She started making a table to represent the proportional relationship between gallons of gas and miles driven. The table shows how far she can travel for each gallon of gas that she uses.
What is the constant of proportionality?
miles per gallon
Answers
2 | 56
4 | a
B | 168
10 | c
If he can go 56 miles with 2 gallons then he can travel 28 miles with 1 gallon.
4 • 28 = a = 112
168/28=b=6
10 • 28 = c = 280
The constant of proportionality of miles per gallon is 28

Jamal hiked on two trails. The first trail was 8 1 3 miles long, and the second trail was 1 3 5 times as long as the first trail. How many miles did Jamal hike? Enter your answer as a mixed number in simplest form.
Answers
Answer:Total distance( miles ) covered by Jamal =21 2/3 miles
Step-by-step explanation:
Step 1
first trail = 8 1/3 miles long
2nd trail = 1 3/5 times as long as the first
Therefore the distance walked in the 2nd trail is 1 3/5 x 8 1/3
changing to improper fraction and solving
=8/5 x 25/3= 40/3
The distance hiked by Jamal in the second trail = 40/3=13 1/3
Step 2
Total distance( miles ) covered by Jamal = first trail +2nd trail
= 8 1/3 + 13 1/3 =21 2/3 miles
Answer:
21 2/3 miles
Step-by-step explanation:
First trail = 8 1/3 miles long
Second trail = 1 3/5 times as long as the first trail
= 1 3/5 × 8 1/3
= 8/5 × 25/3
= 40 / 3
= 13 1/3 miles
How many miles did Jamal hike?
Total miles hiked = First trail + Second trail
= 8 1/3 miles + 13 1/3 miles
= 25/3 + 40/3
= 25+40/3
= 65/3
= 21 2/3 miles
Jamal hiked 21 2/3 miles

Answers
Answer:
62 degrees
Step-by-step explanation:
Every triangle adds up to 180 degrees.
Since you already know two angles, you subtract them from 180 to find the final angle.
180-68.5-49.5=62
Answer:
x=62
Step-by-step explanation:
the sum of the angles of a triangle is always 180 degrees.
so x + 68,5 + 40,5 = 180°
=> x = 180 - (68,5 + 40,5)
=> x = 62
The solutions to the equation f(x) = g(x) are -2 and 1. Iff and g are graphed on the same coordinate plane, which statement must be true?
The functions will intersect at x = -2 and x = 1.
The functions will intersect at y = -2 and y = 1.
Both functions will have y-intercepts at 2 and 1.
Both functions will have x-intercepts at -2 and 1.
Answers
Answer:
The correct option is;
The function will intersect at x = -2 and x = 1
Step-by-step explanation:
The question parameters are
The functions in the question are f(x) and g(x)
The solution to the equation f(x) = g(x) are -2, and 1
Given that the equations, f(x) and g(x), are both given in values of x, their solution will be the x values that satisfies both functions
Therefore, the functions will intersect (have the same values of f(x) and g(x)) at the points of the solutions, which are given as x = -2, and x = 1
The statement that should be true is the function will intersect at x = -2 and x = 1.
Given that,
The solutions to the equation f(x) = g(x) are -2 and 1. If f and g are graphed on the same coordinate plane.Based on the above information, the following information should be considered:
As the solutions represent x values that satisfied the both functions. Also, the functions should intersect that contains the same value i.e. x = -2 and x = 1.Therefore, we can conclude that the first option is correct.

a triangle has side lengths of 14, 23, and 27. Is it a right angle ?
Answers
Answer:
No, it is not
Step-by-step explanation:
Here, we want to check if the lenghts given is that of a right angle triangle
For a right angle triangle, the square of the hypotenuse is equal to the sum of the squares of the two other sides
The hypotenuse represents the longest side
So 27^2 = 14^2 + 23^2
The difference between these is 4, and as such the triangle is not a right angled

Answers
Answer:
x = 2, 1 + 3i, 1 − 3i
Step-by-step explanation:
Find the Roots (Zeros)
x^4 − 6x^3 + 22x^2 − 48x + 40
Set x^4 − 6x^3 + 22x^2 − 48x + 40 equal to 0. x^4 − 6x^3 + 22x^2 − 48x + 40 = 0
Solve for x.
Factor the left side of the equation.
Factor x^4 − 6x^3 + 22x^2 − 48x + 40 using the rational roots test.
(x − 2) (x^3 − 4x^2 + 14x − 20) = 0
Factor x^3 − 4x^2 + 14x − 20 using the rational roots test.
(x − 2) (x − 2) (x2 − 2x + 10) = 0
Combine like factors.
(x − 2)2 (x^2 − 2x + 10) = 0
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
(x − 2)^2 = 0
x^2 − 2x + 10 = 0
Set (x − 2)^2 equal to 0 and solve for x.
Set (x − 2)^2 equal to 0.
(x − 2)^2 = 0
Solve (x − 2)^2 = 0 for x.
x = 2
Set x^2 − 2x + 10 equal to 0 and solve for x.
Set x^2 − 2x + 10 equal to 0. x^2 − 2x + 10 = 0
Solve x^2 − 2x + 10 = 0 for x.
Use the quadratic formula to find the solutions.
−b ± (√b^2 − 4 (ac) )/2a
Substitute the values a = 1, b = −2, and c = 10 into the quadratic formula and solve for x.

Simplify.
Simplify the numerator.
x = 2 ± 6i/ 2.1
Multiply 2 by 1
x = 2 ± 6i/2⋅1
Simplify
2 ± 6i/2
x = 1 ± 3i
The final answer is the combination of both solutions.
x = 1 + 3i, 1 − 3i
The final solution is all the values that make (x − 2)2 (x2 − 2x + 10) = 0 true.
x = 2, 1 + 3i, 1 − 3i

Answers
Answer:
m equals StartFraction y minus b Over x EndFraction
Step-by-step explanation:
The standard equation of a line is expressed as;
y = MX+b where;
m is the slope
cmb is the intercept
We are to get the equivalent expression for finding the slope.
Make m the subject of the formula to get this as shown;
From the equation;
y =MX+b
Subtract c from both sides;
y-b = MX+b-b
MX = y-b
Divide through by x;
mx/x = (y-b)/x
m = (y-b)/x
Heme the required expression is m = (y-b)/x OR m equals StartFraction y minus b Over x EndFraction
