If f(x)=5x+2 and g(x)=x-1 what is f(g(4))

Answers

Answer 1
So g(x) would be 3 because you plug in 4 for x and it would become 4-1 and then you plug in 3 for x in 5x+2 so it would be 5(3)+2 which would equal 17

The first step you should take is to distribute the 2, so if you do that it'll leave you with... [tex]12=-4v+2v+4[/tex]

Then you notice the like terms and then you have to combine them and that'll give you... [tex]12=-2v+4[/tex]

Now you subtract the 4 to both sides and get... [tex]8=-2v[/tex]

Lastly the fun step is to divide the -2 to both sides and to get the answer of...

Answers

Answer:  Casey bought 4 1/2 pounds of apples

The equation is 0.88x - $1.50 = 2.46

x is the unknown number of pounds of apples.

0.88 is the cost per pound,  0.88x is the total cost of the apples before the discount .The discount is $1.50   $2.46 is the cost after the discount.

Part b Step-by-step explanation:

0.88x - $1.50 = 2.46 . Add $1.50 to both sides

0.88x - $1.50 + $1.50 = 2.46 + 1.50  

On left, 1.50-1.50=0 so "cancels'  on the right, add $2.46 + 1.50 = 3.96

0.88x = 3.96  is the cost before discount . Divide both sides by .88

.88x/.88 = 3.96/.88 .  .88/.88 = 1 so 1 'cancels'  leaving x.   3.96/.88 = 4.5

x = 4.5

part c

4.5 is 4 1/2, the (previously unknown) number of pounds of apples.

Casey bought 4 1/2 pounds of apples.

Decrease $820 by 32%​

Answers

Answer:

557.6

Step-by-step explanation:

Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

32% = 32/100 = 32 ÷ 100 = 0.32.

100% = 100/100 = 100 ÷ 100 = 1.

Percentage decrease = 32% × 820

New value =

820 - Percentage decrease =

820 - (32% × 820) =

820 - 32% × 820 =

(1 - 32%) × 820 =

b = b2-4ac

= (-7ab)^2 -4 (6a^2)(-3b^2)

= 49a^2b^2 + 72a^2b^2

Now, x = (7ab +- root 121a^2b^2)÷2(6a²)

sporting goods store is offering a 20% discount on shoes. Mariana also has a $5 off coupon that can be applied to her
purchase. She is planning to buy a pair of shoes that originally costs $89. Will the final price be lower if the discount is applied before the
coupon or if the coupon is applied before the discount? Justify your response

Answers

The discount price will be the same either way. (The commutative property)

20 percent of $89.00= 17.80$

$89.00 - ($5.00 x $17.80) = $66.20

$89.00 - ($17.80 x $5.00) = $66.20

The final price be lower if the discount is applied before the coupon.

What is the fundamental principle of multiplication?

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given that sporting goods store is offering a 20% discount on shoes. Mariana also has a $5 off coupon that can be applied to her

purchase.

She is planning to buy a pair of shoes that originally costs =  $89.

The discount price is the same either way.

Thus 20 percent of $89.00= 17.80$

Therefore, we have;

$89.00 - ($5.00 x $17.80) = $66.20

$89.00 - ($17.80 x $5.00) = $66.20

The slope of the line through (6, -7) and (4, -8)

What is the slope?

The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

where (x₁, y₁) and (x₂, y₂) are the two points that you are trying to find the slope between.

Given;

Two points; (6, -7) and (4, -8)
