Step-by-step explanation:

Answer:

Step-by-step explanation:

 let the degree holder earn  x

 then a masters degree holder earns= (2x-45,000)

the comnined amount of the two degree holders=   (2x-45,000)+x

2x-45000+x=117000

3x=117000+45000

3x=162000

x=162000/3

x=$54000

so bachelor'sdegree hold earns= $54000

a masters degree holder earns= (2(54000)-45,000)

a masters degree holder earns= (108000-45,000)

a masters degree holder earns=$63000

the average= (54000+63000)/2

the average= (117000)/2

the average=$58500

The factors of -24 which should be used to factorize the given quadratic equation are -8 and 3.

It is required to factorize the quadratic equation [tex]x^2-5x - 24[/tex] using the factors of -24.

The required combination of factors should be -8 and 3 because,

[tex]-8+3=-5\\-8\times3=-24[/tex]

Now, factorize the quadratic equation as,

[tex]x^2-5x - 24=x^2-8x+3x-24\\=x(x-8)+3(x-8)\\=(x-8)(x+3)[/tex]

Therefore, the factors of -24 which should be used to factorize the given quadratic equation are -8 and 3.

The ratio of saving money for Lisa and her brother is 5 : 2.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, Lisa and her brother are saving money to go on a trip. For every $2 Lisa saves, her brother saves $5.

Therefore, The ratio of saving money for Lisa and her brother is,

Lisa : Her brother = 5 : 2.

Answer:

x = 1

Step-by-step explanation:

4x+7(3x-3) = 9-5x (equation)

4x+21x-21 = 9-5x (simplify)

25x-21 = 9-5x (combine like terms)

30x-21 = 9 (add 5x to each side)

30x = 30 (add 21 to each side)

x = 1 (divide each side by 30)

Answer:

He paid $2.35 for each pair of socks.

An equation using the variable S is

$77.99 = 9S + (3 × $8.28) + $32

Step-by-step explanation:

Let S be the cost of a pair of socks

From the question, Mark purchase nine pairs of socks, that is, the total cost of the pairs of socks is 9S

He purchase three packages of undershirts for $8.28 each; the total cost of the three packages of shirt will be 3 × $8.28 = $24.84

and he also purchase a pair of pants for $32

Since he spent a total of $77.99, we can write that

$77.99 = 9S + (3 × $8.28) + $32

Now, we can determine S, the cost of a pair of socks

$77.99 = 9S + (3 × $8.28) + $32

$77.99 = 9S + $24.84 + $32

$77.99 = 9S + $56.84

9S = $77.99 - $56.84

9S = $21.15

S = $21.15/9

S = $2.35

Hence, he paid $2.35 for each pair of socks.

Step-by-step explanation:

The slope of this line is -4/3. You can calculate the slope by picking two points on the graph and calculating the rise/run (the vertical distance between the two points divided by the horizontal distance). The line also intersects the point (3,-2) which you can find if you go to the right 3 and down 2 on the graph.

Answer:

3.84*10^-2 s the answer:)

Step-by-step explanation:

Answer:

y=0.75m+45

Step-by-step explanation:

when you bought the car it was 45, that doesnt change so its a constant

but every mile you drive, it changes, therefore it becomes the dependent or the rate :)

so we just make it into an equation of

y=0.75m+45

where y= the total amount of money owed

and if you wanted to solve for how far the car drove, plug in the 222.5 in for y, as that was the amount owed and solve!

222.5=0.75m+45

177.5=.75m

now divide by .75

m= 236 2/3 miles

Answer:x=2

Step-by-step explanation:

Answer:

Step-by-step explanation:

Correct steps to find the value of 'a' should be,

Braulio's synthetic division should be,

-1  |     1       5         a          -3           11

               -1        -4        (4 - a)     (a - 1)  

         1      4     (a - 4)     (1 - a)     (a + 10)

Here remainder is (a + 10).

So (a + 10) = 17 ⇒ a = 7

Braulio Incorrectly found a value of 'a' because he should have used (-1) instead of 1.

Zahra's calculation by remainder theorem should be,

p(x) = x⁴ + 5x³ + ax² - 3x + 11

p(-1) = (-1)⁴ + 5(-1)³ + a(-1)² - 3(-1) + 11

      = 1 - 5 + a + 3 + 11

      = (a + 10)

Since, remainder of the solution is 17,

(a + 10) = 17 ⇒ a = 7

Zahra incorrectly found the value of 'a' because she incorrectly solved the powers to (-1).

Answer: incorrectly, should have used -1 instead of 1

incorrectly, incorrectly applied the powers to -1
