What is the slope of the line that passes through the points ( -9, -8 ) and ( -15, - 16 ) In simplest form please
Answer:
4/3
Step-by-step explanation:
The slope formula is y2-y1/x2-x1
take the y from one of the points and subtract the y from the other point, the divide that by the x of the first y you picked and subtract the x of the second y
(-16)-(-8)/(-15)-(-9)
-8/-6
simplify
4/3
the slope is 4/3
[tex] {x}^{4} - 6 {x}^{3} + 22 {x}^{2} - 48x + 40[/tex]
find the zeros
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.
2 ± (√(−2)^2 − 4 ⋅ (1 ⋅ 10))/2 ⋅ 1
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

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.
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.

How do I do this? Anyone know
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
Which statement describes a unit rate? * 5 points Mary paid $2.50 for 3 bottles of water. Ricardo paid $17.00 for 3 pumpkins. Katherine paid $1.25 for 1 bottle of water. Joshua paid $6.00 for 3 masks.
Answer:
Katherine paid $1.25 for 1 bottle of water.Step-by-step explanation:
What is the unit rate?In this context, a unit rate is defined as the amount in dollars paid for one unit of a commodity.
In the given options, all the items are above one except
option C( Katherine paid $1.25 for 1 bottle of water.)
hence all the other amount does not correspond to the unit rate
Mary paid $2.50 for 3 bottles of water. not a aunit rate
Ricardo paid $17.00 for 3 pumpkins. not a unit rate
Katherine paid $1.25 for 1 bottle of water. a unit rate
Joshua paid $6.00 for 3 masks. not a unit rate

a triangle has side lengths of 14, 23, and 27. Is it a right angle ?
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

angle 9 and angle 10 are corresponding and complementary angles formed by two parallel lines cut by a transversal. Find the measure of angle 9.
Answer:
45 Degrees
Step-by-step explanation:
9 and 10 are corresponding meaning that they will be the same. They are also complementary, so they equal 90 degrees when added. 90/2 is 45.

Mary can read 22 pages in 30 minutes. How long would it take her to read a 100 page book? Write your answer in hours and minutes
Answer:
Step-by-step explanation:
Step one:
given data
we are told that Mary can read 22 pages in 30 minutes (0.5 hours)
let us find the number of pages per minute she can read
rate= quantity/time
rate= 22/30
rate=0.73 pages per minute
or
rate= 22/0.5
rate= 44 pages per hour
Step two:
Required
time taken to read 100 pages
t= quantity/rate
t=100/0.73
t=136 pages per minute
or
t= 100/44
t=2.3 pages per hour

Which is an equivalent equation solved for the slope, m? m = yx + b m = m equals StartFraction y minus b Over x EndFraction. m = m equals StartFraction y Over x EndFraction minus b. – b m = y – m equals y minus StartFraction b Over x EndFraction.
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

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.
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
