Answer: the cost of riding the taxi for 8 miles is $9
Step-by-step explanation:
The taxi company charges a flat fee of 3.00 for using the taxi and 0.75 per mile. This means that the total cost of using the taxi and travelling x miles would be
3 + 0.75x
This is the equation representing the situation.
To find the cost of riding the taxi for 8 miles, we would substitute x = 8 in our equation. It becomes
Therefore, the total cost of riding the taxi for 8 miles would be
3 + 0.75 × 8
= 3 + 6 = $9
Answer:
15/2, 13/2.
Step-by-step explanation:
Here's a graph as well.
Answer in fraction form = (15/2, 13/2)
Answer in decimal form = (7.5, 6.5)
========================================================
Explanation:
To get the midpoint, we average the two endpoint values. We handle the x and y coordinates separately.
The x coordinates of each point are 6 and 9. They average to (6+9)/2 = 15/2 = 7.5; so you add up the x coordinates and divide by 2.
The y coordinates are handled the same way. Add them to get 4+9 = 13 and then divide by 2 to get 13/2 = 6.5
The midpoint is (15/2, 13/2) = (7.5, 6.5)
Answer:
y = - x +
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given the line with equation
y = - x + 7 ← in slope- intercept form
with slope m = -
• Parallel lines have equal slopes , then
y = - x + c ← is the partial equation of the parallel line
to find c, substitute the point (3, 3 ) for x/ y into the partial equation
3 = - (3) + c = - + c ( add to both sides )
+ = c , that is
c =
y = - x + ← equation of parallel line
The equation of the line passing through point (3,3) and parallel to y = -(1/6)x + 7 is y = -(1/6)x + 3.5, which is achieved by knowing that parallel lines have the same slope and substituting the coordinates of the given point into the y = mx + b (slope-intercept form) and solving for the y-intercept 'b'.
The question asks for an equation of a line that is parallel to the equation y = -(1/6)x + 7 and also passes through the point (3,3). First, it's significant to understand that parallel lines share the same slope. Looking at the equation y = -(1/6)x + 7, we can see that the slope, or 'm' value, is -1/6. Therefore, the slope of our new line will also be -1/6. The conventional form of the equation for a line is y = mx + b where m is the slope and b is the y-intercept. Since we know the slope and have a point that lies on the line, we can substitute these values into this formula to solve for 'b'.
Here's how we do it:
First, substitute the point's coordinates into the equation for the line: 3 = (-1/6)*3 + b
This simplifies to: 3 = -1/2 + b
Then solving for 'b', we get: b = 3 + 1/2 = 3.5
Therefore, the equation of our new line that is parallel to the original line and passes through the point (3,3) is y = -(1/6)x + 3.5.

Answer:
The expression of h as function of x is h =
Step-by-step explanation:
Given as :
The distance of blimp (AB) = 5500 feet
The slanted distance to the pagoda (BC) = d feet
The horizontal distance (AC) = h
Let the angle made between slanted distance and horizontal distance be Ф
So , cos Ф = =
And sin Ф = =
∵, cos²Ф = 1 - sin²Ф
So, =
Or, =
Or, h² = d² - 5500²
∴ h =
Or, h =
Hence The expression of h as function of x is h = Answer
Answer:
x = 77 - 2y
y = -x/2 + 77/2
Step-by-step explanation:
2x + 4y - 31 = 123
add 31 both sides
2x + 4y - 31 + 31 = 123 + 31
2x +4y = 154
Solve for x
2x = 154 - 4y
divide both sides by 2
x = 77 - 2y
solve for y
2y = 77 - x
divide both sides by 2
y = 77/2 - x/2
I belive the answer is no. Tell me if im doing this wrong, but the square root of 380 is a decimal number.
