A mountain bike costs $675. If the sales tax is 8%, find the total cost of the bike. Round to the nearest cent, if
necessary
Answer:
$729.00
Step-by-step explanation:
The tax is ...
0.08 × $675 = $54.00
So, the total cost of the bike is ...
$675 +54 = $729.00
Given: -8(x+1)=-5(x+10) prove x=14

Francesca plans to compete in a biathlon that involves running and cycling. During one training session, she covered a total distance of 46 miles in four hours. If she ran at a rate of 5 mph and cycled at a rate of 15 mph, how long did she spend cycling?
Answer:
.
Step-by-step explanation:
Use the distance formula
d = vt
where:
d = distance (miles)
v = speed (mph)
t = time (hours)
Let x = run time
Let y = bike time
Total time: x + y = 4
Using these variables we can write an equation representing the formula.
dTotal = drun + dbike
49 = 9x + 22y
Next, we get the equation in terms of only x or y. We'll get it in terms of x.
49 = 9x +22(4 - x)
49 = 9x + 88 - 22x
-39 = -13x
3 = x
Plug in this value of x into the variables to find the distance for each part.
run distance = 9x
bike distance = 22(4 - x)

Answer:
6x^2 + 23x + 21
Step-by-step explanation:
3x+7 x 2x+3
= 3x(2x) + 3x(3) + 7(2x) + 7(3)
= 6x^2 + 9x + 14x + 21
= 6x^2 + 23x + 21

Answer:
9
Step-by-step explanation:
The absolute value of any number is just its distance from 0.
-4 is 4 away from 0, so its absolute value is 4.
-5 is 5 away from 0, so its absolute value is 5.
Therefore, the equation is basically just asking what is 4 + 5, which is 9 :D.
Answer:
9
Step-by-step explanation:
The bars around the two numbers imply that it wants you to find the absolute value. Absolute value is the distance a number is from zero since distance is always positive to find the answer just make the number positive. Following this rule l-4l=4 and l-5l=5. Then add them together 4+5=9.

What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given is an equation of a line, we need to find that on which of the given points it lies,
So, we will put the points one by one, the point which stratify the equation will be the answer.
The equation :- y = 2x-4
1) (1, -2)
Put x = 1, y = -2 in the equation,
2(1)-4
= 2-4 = -2
LHS = RHS
Since, point (1, -2) satisfy the equation therefore, the line will pass through it.
Hence, (1, -2) is the coordinates that exists on the line y = 2x - 4

Which statement correctly describes the inverse of the following function?
Need the answer ASAP
Answer:
(-7, 5)
Step-by-step explanation:
Since both of them are equal to y, you could just set them equal to each other.
5/7x + 4 = -1/7x - 2
6/7x = -6
x = -7
Now just plug x back to one of the equations:
y = -1/7*(-7) - 2 = 7 - 2 = 5
Therefore, the solution to the system is (-7, 5)

Line f has a slope of -3/4 line g is perpendicular to f. What is the slope of like g
Answer:
Slope of line g = [tex]1\frac{1}{3}[/tex]
Step-by-step explanation:
Line f has a slope of [tex]-\frac{3}{4}[/tex] Line g is perpendicular to f* Mathematics rule: If two lines are perpendicular to each other, then the product of their slopes is equal to -1 .
∴ [tex]-\frac{3}{4}[/tex] × slope of line g = -1
Slope of line g = -1 ÷ [tex]-\frac{3}{4}[/tex] = 4/3 = [tex]1\frac{1}{3}[/tex]
