I really need help. Can you please show your work too.

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

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

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

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.

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,

Based on the above information, the following information should be considered:

Therefore, we can conclude that the first option is correct.

6. Would be Sports City

Step-by-step explanation:

Take 180*.15= 27

Subtract 27 from 180 and you get 153.

200*.20=40

Subtract 40 from 200 and you get 160.

For 5 just multiply the discounted price by 2.

I hope I answered your question.

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

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

Answer:

Step-by-step explanation:

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

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

Answer:

[tex]Total\ Length = \frac{35}{8}\ ft[/tex]

Step-by-step explanation:

Given

[tex]Length = \frac{5}{8}\ ft[/tex]

[tex]Number = 7[/tex]

Required

Determine the total length

Since, he ribbons are of the same lengths.

The total length is calculated as:

[tex]Total\ Length = Length * Number[/tex]

[tex]Total\ Length = \frac{5}{8}\ ft * 7[/tex]

[tex]Total\ Length = \frac{5 * 7}{8}\ ft[/tex]

[tex]Total\ Length = \frac{35}{8}\ ft[/tex]

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
