Answer 1

Answer:

x = -5

y = 20

Step-by-step explanation:

3x + y = 5

3x - 3x + y = 5 - 3x

y = 5 - 3x

--------------------------------------------------------

4x + 2y = 20

4x + 2(5 - 3x) = 20

4x + 2(5) + 2(-3x) = 20

4x + 10 - 6x = 20

10 - 2x = 20

10 - 10 - 2x = 20 - 10

-2x = 10

-2x ÷ -2 = 10 ÷ -2

x = -5

--------------------------------------------------------

y = 5 - 3x

y = 5 - 3(-5)

y = 5 + 15

y = 20

Given f(x)=4x+5 and g(x)= x^2+x; find (f∘g)(-5)
Please show all steps thank you

Answers

Answer:

[tex](f\circ g)(-5)=85[/tex]

Step-by-step explanation:

We are given:

[tex]\displaystyle f(x)=4x+5\text{ and } g(x)=x^2+x[/tex]

And we want to find:

[tex](f\circ g)(-5)[/tex]

This is equivalent to:

[tex]\displaystyle =f(g(-5))[/tex]

So, we will evaluate g(-5) first, which yields:

[tex]\displaystyle g(-5)=(-5)^2+(-5)=25-5=20[/tex]

So:

[tex]=f(g(-5))=f(20)[/tex]

Then:

[tex]\displaystyle f(20)=4(20)+5=80+5=85[/tex]

Therefore:

[tex](f\circ g)(-5)=85[/tex]

More generally, this triangle has sides in the ratio 3x:4x:5x

Write an algebraic expression to represent the phrase:

Twenty five less than the quotient of a number and six.

Answers

Answer:  n/6 - 25

Step-by-step explanation:

We can use the vairiable n to represent the unknown number.

Because the question asks ofr the quotient of n and six, we can write the term as n/6

Because the question also asks for 25 less then that term, we can write the whole statement as:  n/6 - 25 .

Therefore, the algebraic expression to represent the phrase Twenty-five less than the quotient of a number and six is n/6 - 25.

Hope this helps and good luck! :D

Answer:

(x / 6) - 25

What is the price of the items Nakita bought?
20 Nakita bought items at a grocery store
she bought 2 boxes of crackers for $3.50 each
she used a coupon for $0.80 off the price of each box of crackers
she bought a jar of peanut butter for $4.85.
she bought a package of juice boxes for $2.40.
she used a coupon for $3.00 off the total price of the items she bought
This expression can be used to determine the price of the items Nakita bought
[2(3.50 - 0.80) + 4.85 + 2.401 - 3.00
A $6.95
B $10.45
C $9.65
D $12.65

Answers

Answer:

B $10.45

Step-by-step explanation:

Fist you find how much the 2 boxes of cracker cost

$3.50 * 2 = $7

Then subtract the amount of 2 crackers by the $0.80 coupon

$7 - $0.80 = $6.20

Then add that amount to the cost of a jar of peanut butter

$6.20 + $4.85 = $11.05

Then add that about for with the amount of a package of juice boxes

$11.05 + $2.40 = $13.45

Then subtract the total amount to the $3.00 coupon

$13.45 - $3.00 = $10.45

B $10.45 is your answer
