F(x) = x + 4: find f(4) and f(x) = 10

Answer:

-11

Step-by-step explanation:

-1/2y=1/2+5

- 1/2 y = 1+10 (by taking lcm)

               2  

 [tex]\frac{-1}{2}[/tex] x 2y = 11

y = -11

[tex] \frac{ - 1}{ \: \: \: 2} y = \frac{1}{2} + 5[/tex]

[tex] \frac{ - 1}{ \: \: \:2} \times y = \frac{1}{2} + 5[/tex]

[tex] \frac{ - 1}{ \: \: \:2} \times y = \frac{11}{2} [/tex]

[tex]y = \frac{11}{2} \div \frac{ - 1}{ \: \: \:2} [/tex]

[tex]y = \frac{11}{2} \times \frac{ \: \: \: 2}{ - 1} [/tex]

[tex]y = \frac{ \: \: 22}{ - 2} [/tex]

[tex]y = - 11[/tex]

The value of y = -11

Therefore :-

[tex] \frac{ - 1}{ \: \: \:2} \times - 11 = \frac{1}{2} + 5[/tex]

Answer:

The insulation fee for 175 square feet of carpet is $237.

Step-by-step explanation:

The amount of money, f(x), that it cost to purchase x square feet of the carpet is:

f(x)= 8x

The insulation fee,g(x), is $125 more than 8% of the cost of the carpet,f(x), we have

g(x)=8% of f(x)+125

[tex]\Rightarrow=\frac{8}{100}\times (8x)+125[/tex]

[tex]\Rightarrow=0.64x+125[/tex]

The insulation fee for 175 square feet of carpet,

i.e for x=175

[tex]g(x=175)=0.64\times175+125=237[/tex]

Hence, the insulation fee for 175 square feet of carpet is $237.

Answer:

C

Step-by-step explanation:

It is C because it has a proportional value through the diameter of the graph. With that you will also be able to figure this out by seeing that the light in between the graph is even. The numbers that the graph a line with are similar to the answer C.

Answer: D

Step-by-step explanation:

Answerer: Darrell has already donated $23 to the foundation, so f (0) =$23.

Because x represents the number of weeks, and Darrell is contributing $1 every day, Monday through Friday, he will contribute a total of $5 per week. So, the total amount donated will increase by $5 each week. Therefore, the recursive function will be f (x) =f(x - 1) + $5, where f ($23).

Answer:

0.155625 or .16 cents per ounce

Step-by-step explanation:

2 tons is 64000 ounces so 9960 divided by 64000 is .155625

Answer:

angle2=23°

angle7=angle5

angle2=angle6

so,angle8=23°

total angle = 180°

angle7=180°-46°=134°÷2=67°

Using corresponding angles are equal property we found that m∠7 = 157°

When two parallel lines are intersected by an transversal line then the pair of angles formed on one same side of transversal on both parallel lines are corresponding angles. As in the figure attached ∠ 1 and ∠5 are  corresponding angles.∠4 and ∠8 are also corresponding angles.

Corresponding angles are always equal.

Given that x and y are parallel lines.

Then ∠2 and ∠6 are corresponding angles , therefore m ∠2 = m ∠6

Given that m∠2 = 23°

⇒ m∠6 = 23°

As ∠7 and ∠6 are on same line hence they are supplementary

m∠7  + m∠6 = 180°

⇒m∠7 + 23° =180°

⇒m∠7  =180°- 23° = 157°

Therefore, the measure of angle ∠7 is 157°

Answer:

acute

Step-by-step explanation:

TAG

think of the angle, the gap is small and T is close to G

if it would be right the T would be upright

if it was straight T would lay flat corresponding to G making a line

if it was obtuse the gap would surpass the right angle outward

Step-by-step explanation:

AB || CD and AC is oblique ;

So : Angle ( BAC ) = Angle ( DCA )

_________________________________

∆ ABC - ∆ ACD :

(1) AB = CD

(2) Angle ( BAC ) = Angle ( DCA )

(3) AC = AC

So According to (1) , (2) , (3) :

∆ ABC =~ ∆ ACD

Answer:

x = 45

Step-by-step explanation:

[tex]540 + 6x = 810[/tex]

Step 1 : Collect like terms

[tex]6x = 810 - 540[/tex]

Step 2 : Simplify

[tex]6x = 270[/tex]

Divide both sides of the equation by 6

[tex] \frac{6x}{6} = \frac{270}{6} [/tex]

Step 4 : Simplify

[tex]x = 45[/tex]

I hope it helps :)

Answer:

Well...X=45

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:540+6*x-(810)=0

Pull out like factors :-270 + 6x  =   6 • (x - 45)

Solve  :    x-45 = 0::

Add  45  to both sides of the equation:  x = 45

Answer:

12, 13, 14

Step-by-step explanation:

Three consecutive numbers means three numbers in a row, so if n is the first number, the second number is one more than  n (which is n+1) and the third number is one more than that (which is n+2)

So three times (3 x) the first number (n) is equal to (=) nine more than (9 +) the sum of the other two ( (n+1) + (n+2) )

3 times n can be written as 3n

So 3n = 9 + (n+1) + (n+2)

3n = 9 + n + 1 + n + 2

3n = 9 + 1 + 2 + n + n

3n = 12 + 2n

Subtract 2n from each side

3n - 2n = 12 + 2n - 2n

1n = 12

n = 12

So the first number is 12, the second number is 12 + 1 (13) and the third number is 12 + 2 (14)

The numbers are 12, 13, 14

Answer:

m = 0

Step-by-step explanation:

To find the slope of a line, use the equation:

m = y2 - y1 / x2 - x1

Then, substitute in numbers:

m = 0 - 0 / -6 - 4

m = 0 / -10

m = 0

Therefore, the slope of the line is 0, meaning it has zero slope.
