Answer:
x = 24.5
Step-by-step explanation:
the angles form a straight line, and a straight line equals to 180°
=> (5x + 8) + (3x - 24) = 180
=> 8x = 196
=> x = 24.5

Doug entered a canoe race. He rowed 3 1/2 miles in 1/2 hour what is his average speed in miles per hour
Answer: 7 miles per hour
Step-by-step explanation:
3 1/2 miles = 7/2 miles
1/2 hours= 30 minutes
So,
In 30 mins, travelled 7/2 miles
In 1 min, travelled 7/2 ÷ 30= 7/2× 1/30 = (7×1)/(2×30) = 7/60 miles
In 60 mins, travelled (7×60)/60 miles = 420/60 miles = 7 miles.
Hence, the speed is 7 miles per hour.

The following ratio table has a mistake. Select the value that does not create an equivalent ratio. Ratio Table 1 2 3 6 5 10 10 12
Answer:
10 and 12
Step-by-step explanation:
10 and 12
if I divide 3 and 6 by 3 I get 1/2
if I divide 5 and 10 by 5 I get 1/2
1/2 is the first one listed
I cannot reduce 10/12 and get 1/2, I get 5/6

How to find the rational zeros of a function
Answer:
Step-by-step explanation:
Find the zeroes of the function f ( x ) = x 2 + 12 x + 32
First, because it's a polynomial, factor it f ( x ) = ( x + 8 ) ( x + 4 )
Then, set it equal to zero 0 = ( x + 8 ) ( x + 4 )
Set each factor equal to zero and the answer is x = − 8 and x = − 4 .

At a little-known vacation spot, taxi fares are a bargain. A 28-mile taxi ride takes 42 minutes and costs $16.80. You want to find the cost of a 50-mile taxi ride. What unit price do you need?
Answer:
Unit Cost = 0.6
Cost for 50 mile taxi ride = $30
Step-by-step explanation:
We are given the following information in the question:
Length of taxi ride = 28 miles
Time taken by taxi ride = 42 minutes
Cost of taxi ride = $16.80
We have to find cost of a 50 mile ride.
In order to do so, we have to find the unit cost of distance covered by ride which is the unit cost per mile of the ride that is the cost for 1 mile of taxi ride.
Our Formula:
Unit Cost = Cost for 1 mile of taxi ride = cost of taxi ride / distance covered by taxi ride
Using the values given we can use the formula so
unit cost = 16.80 / 28 = 0.6
Cost of 50 mile taxi ride
0.6 x 50 = 30
Henc costing $30 for a 50 mile taxi ride

What's the domain of this function graph
Answer:
D) [0, ~)
Step-by-step explanation:
Domain of a Function:
the domain of a function is the set of values of x, the independent variable, that are responsible for the graph of the function.
For Example:
suppose, we have a function:
f(x) = 3x - 1
and it's domain is {1, 2, 3}
that means, the corresponding value of f(x) to these 3 values of x will be DEFINED, I.e., they exist and can be plotted on a graph.
The given function:
Therefore, for the given function, it's domain will be those values of x(the ones plotted on the horizontal line), that give some value to the function ,i.e., for which we can draw it's graph.
and since the graph starts from x = 0 and continues towards infiinity
(the arrow on the curve shows that the graph continues and hasn't yet come to a stop.)
So, that way we got [0, ~). ^^
can someone help me with this quickly please
Plug in -3 for f(x) into the first equation.
-3 = x^2 - 5x + 3
x^2 - 5x + 6 = 0
Factor!
(x - 3)(x - 2) = 0
Set each binomial equal to 0 to get the x-value of the point.
x = 3
x = 2
Plug each x-value back into the first equation (the answer should be -3, though it's always good to check) to get the y-value.
(3)^2 - 5(3) + 3
9 - 15 + 3
-6 + 3
-3
(2)^2 - 5(2) + 3
4 - 10 + 3
-6 + 3
-3
Ordered pairs of the solutions for this system of equations: (2, -3) and (3, -3)

Find the midpoint of the segment with the given endpoints.
(-10,- 6) and (-3,7)
Step-by-step explanation:
in essence, these 2 points are the Hypotenuse of a right-angled triangle. the legs are the coordinate differences between the 2 points creating the 3rd point of that triangle at (-10, 7) : the x coordinate of one point, and the y coordinate of the other.
now, we are looking for the midpoint. this midpoint cuts the original line/hypotenuse in half creating a scaling factor of 1/2.
when we create now a similar triangle based on that "half- Hypotenuse", we need to use the same scaling factor also on the legs (the coordinate differences).
so, when we cut the coordinate differences also in half, we get the coordinates for the midpoint on the main line.
xm, ym are the coordinates of the midpoint.
xm = (x1 + x2)/2 = (-10-3)/2 = -13/2 = -6.5
ym = (y1 + y2)/2 = (-6+7)/2 = 1/2 = 0.5
so, the midpoint is (-6.5, 0.5)
find the 21st term of the AP 1,3,5,7,
Answer:
are you Philippines ty points
Answer:
a₂₁ = 41
Step-by-step explanation:
The nth term of an AP is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 1 and d = a₂ - a₁ = 3 - 1 = 2 , then
a₂₁ = 1 + (20 × 2) = 1 + 40 = 41
Which of the following is the graph of y=√-x-3 EndRoot?
9514 1404 393
Answer:
3
Step-by-step explanation:
The square root function (√) only gives positive values, so graphs 1 and 4 make no sense.
When x = -3, the y-value is 0, consistent with graph 3.
