Answers

Answer 1

Answer: 35 + 8w = 179.40
8w = 179.40 - 35
8w = 144.40
w = 144.40/8
w = 18.05 per week

Baseball tickets cost $15 for general admission or $20 for box seats. the sales tax on each ticket is 8%. What is the final cost of each type of ticket

Answers

Answer:

the final cost of a box seat ticket is $21.60.

Step-by-step explanation:

To calculate the final cost of each type of ticket, we need to add the sales tax to the original ticket prices.

For the general admission ticket:

Original price = $15

Sales tax = 8% of $15 = 0.08 * $15 = $1.20

Final cost of general admission ticket = Original price + Sales tax = $15 + $1.20 = $16.20

Therefore, the final cost of a general admission ticket is $16.20.

For the box seat ticket:

Original price = $20

Sales tax = 8% of $20 = 0.08 * $20 = $1.60

Final cost of box seat ticket = Original price + Sales tax = $20 + $1.60 = $21.60

Therefore, the final cost of a box seat ticket is $21.60.

The graph of f(x) = x is given. Which equation will translate the graph 3 units down?A. g(x) = 3x
B. g(x) = -3x
C. g(x) = x - 3
D. g(x) = x + 3

Answers

Answer:

C. g(x) = x - 3

Step-by-step explanation:

The given function is

$f(x)=x$

When we transform a parent function, we can translate it, rotate it, stretch it or expand it. However, in this case, the problem is asking for translations.

If we want to translate the function downside, we just have to subtract units from f(x), like this f(x) - u.

If we want to translate the function horizontally, we have to add or subtract units to the x-variable of the function.

So, in this case, to move the parent function 3 units down, we have to subtract 3 units.

Therefore, the transformation would be

$g(x) = x-3$

So, the right answer is C.

Answer:

g(x)=x-3

How do I solve for x and state the restriction if (a-c)/(x-a)=m

Answers

$(a-c)/(x-a)=m;\ D:x\neq a\n\nm(x-a)=a-c\n\nmx-ma=a-c\n\nmx=a-c+ma\ \ \ \ /:m\neq0\n\nx=(a-c+ma)/(m)$

$(a - c)/(x - a) = m$

$(x - a) (a - c)/(x - a) = m ( x - a)$

$a - c = mx - am$

$a - c + am = mx$

$(a)/(m) - (c)/(m) + (am)/(m) = x$

$(a - c)/(m) + a = x$

Write "252 miles per 8 gallons " as a rate in simplest form

Answers

Hi there! 252 miles per gallon would be 252 miles/8 gallons. The GCF of 252 and 8 is 4 so we are going to divide by 4. 252÷4=63 and 8÷4=2. In this case, we have a fraction of 63/2.

Answer:

Rate per gallon in simplest form is, $(63)/(2)$
