Answer:
y = 10 + 2.50h
$25
Step-by-step explanation:
first the equation is written as such because she pays $10 no matter how many hours she rides. She also pays 2.50 for each hour so use h as the variable to define number of hours she rides the bike.
since equation is y = 10 +2.50h
and h = 6 hours, substitute and find the total cost
y = 10 + 2.50(6)
= 10 + 15
= $25

What is the value of the expression when x = 4?
8x^2 + 3x
Answers
Answer:
The value of the expression at x = 4 is 140
Step-by-step explanation:
Let us solve the question
∵ The expression is 8x² + 3x
∵ x = 4
→ To find the value of the expression at x = 4 substitute x by 4 in
the expression, then calculate the value of it
∵ The value of the expression = 8(4)² + 3(4)
→ Solve the power first
∴ The value of the expression = 8(16) + 3(4)
→ Simplify each term using multiplication
∴ The value of the expression = 128 + 12
→ Add the terms
∴ The value of the expression = 140
∴ The value of the expression at x = 4 is 140

The radius of a circle is 8 kilometers. What is the length of a 90° arc?
Answers
C=pi(D)
C=pi(16) (16 because diameter is just 2x the radius, which is 8)
C=16pi
So, divide this by 4, and the arc will be 4pi.
The length of a 90° arc is 4π kilometers.
What is Circle?Circle is a two dimensional figure which consist of set of all the points which are at equal distance from a point which is fixed called the center of the circle.
Given that,
radius of the circle = 8 kilometers
Arc length can be found by the formula,
Arc length = 2πr (x/360°) where r is the radius, x is the measure of the arc in degrees.
Substituting,
Arc length = 2π × 8 (90°/360°)
= 4π
Hence the length of the arc is 4π kilometers.

What is the solution to the equation square root 2x + 6 - square root x + 4 = 1
Answers
raAnswer:
x = 5
Step-by-step explanation:
Original equation = [tex]\sqrt{2x+6}[/tex] - [tex]\sqrt{x+4}[/tex] = 1
Remove square roots
[tex]x^{2}[/tex] + 2x +1 = 4x +16
Subtract 16 from both sides
[tex]x^{2}[/tex]+ 2x +1 = 4x +16
-16 -16
---------------------------
[tex]x^{2}[/tex] + 2x- 15= 4x
Subtract 4x from both sides
[tex]x^{2}[/tex] + 2x - 15 - 4x= 4x - 4x
= [tex]x^{2}[/tex] - 2x - 15 = 0
THIS EQUATION HAS 2 rational roots. {x1,x2} = {5,-3}
CHECK THAT THE FIRST SOLUTION IS CORRECT (5)
Original equation, root isolated, after tidy up
[tex]\sqrt{2x+6}[/tex] = [tex]\sqrt{x+4}[/tex]
Plug in 5 for x
[tex]\sqrt{2\cdot (5)+6}[/tex] = [tex]\sqrt{(5)+4+1}[/tex]
Simplify
[tex]\sqrt16}[/tex] = 4
Solution checks !!
Solution is: x = 5
CHECK THAT THE SECOND SOLUTION IS CORRECT (-3)
Original equation, root isolated, after tidy up
[tex]\sqrt{2x+6}[/tex] = [tex]\sqrt{x+4}[/tex]
Plug in -3 for x
[tex]\sqrt{2\cdot (-3) +6}[/tex] = [tex]\sqrt{(-3)+4+1}[/tex]
Simplify
[tex]\sqrt{0}[/tex] = 2
Solution does not check
0 ≠ 2
So, the answer is x = 5

The equation of line L is 3x - 8y + 20 = 0.
Find the gradient of line L.
Answers
Answer:
The slope or gradient of the line L will be: m = 3/8
Step-by-step explanation
We know that the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where m is the slope or gradient and b is the y-intercept
Given the equation of the line
[tex]3x - 8y + 20 = 0[/tex]
Let us solve for 'y' to write the equation in the slope-intercept form
[tex]3x - 8y + 20 = 0[/tex]
Add -3x to both sides
[tex]3x-8y+20+\left(-3x\right)=0+\left(-3x\right)[/tex]
simplify
[tex]-8y+20=-3x[/tex]
subtract 20 from both sides
[tex]-8y+20-20=-3x-20[/tex]
simplify
[tex]-8y=-3x-20[/tex]
Divide both sides by -8.
[tex]\frac{-8y}{-8}=\frac{-3x-20}{-8}[/tex]
[tex]y=\frac{3}{8}x+\frac{5}{2}[/tex]
Thus, comparing with the slope-intercept form
[tex]y = mx+b[/tex]
[tex]m\:=\:\frac{3}{8}[/tex]
Thus, the slope or gradient of the line L will be: m = 3/8

Answers
Hello!
[tex]\large\boxed{x = 5}[/tex]
11 - (3x + 1) = 7(x - 6) + 2
Distribute the coefficients outside of the parenthesis:
11 - (3x) - (1) = 7(x) + 7(-6) + 2
Simplify:
11 - 3x - 1 = 7x - 42 + 2
Combine like terms:
10 - 3x = 7x - 40
Add 3x to both sides to isolate x:
10 = 10x - 40
Add 40 to both sides:
50 = 10x
Divide both sides by 10:
x = 5
Answer:
11-3x-1=7x-42+2
