A truck driver drove 49 miles in 1 1/3 hours. What was the average speed, in miles per hour, for this trip?
Answer:
B. [tex]36\frac{3}{4}\ mph[/tex]
Step-by-step explanation:
The formula for average speed:
[tex]S_{average} = \frac{distance}{time}\\\\S = \frac{49\ miles}{1\frac{1}{3}\ hours}\\\\S = 36.75 = 36\frac{3}{4}\ mph[/tex]

The image shows a circle centered at point O angle AOB Measures at 42 degrees.
What is the Measure of the angle acb explain your reasoning
Answer:
∠ ACB = 21°
Step-by-step explanation:
the inscribed angle ACB is half the central angle AOB , subtended by the same arc AB , then
∠ ACB = [tex]\frac{1}{2}[/tex] ∠ AOB = [tex]\frac{1}{2}[/tex] × 42° = 21°

Answer:
[tex]\large{\boxed{\sf g(x) = \dfrac{1}{2} |x - 4| +7}}[/tex]
Explanation:
Absolute value of a graph formula:
y = a |x -h| + kIdentify the vertex : (h, k) = (4, 7)
Take two points: (4, 7), (6, 8)
[tex]\sf Find \ slope \ (a) : \sf \ \dfrac{y_2 - y_1}{x_2- x_1} \ = \ \dfrac{8-7}{6-4} \ = \dfrac{1}{2}[/tex]
Putting them together : [tex]\bf g(x) = \dfrac{1}{2} |x - 4| +7[/tex]
Answer:
[tex]g(x)=\dfrac{1}{2}|x-4|+7[/tex]
Step-by-step explanation:
Translations
For [tex]a > 0[/tex]
[tex]f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}[/tex]
[tex]f(x)+a \implies f(x) \: \textsf{translated}\:a\:\textsf{units up}[/tex]
[tex]y=a\:f(x) \implies f(x) \: \textsf{stretched parallel to the y-axis by a factor of}\:a[/tex]
-----------------------------------------------------------------------------------------
Parent function: [tex]f(x)=|x|[/tex]
(with vertex at the origin)
From inspection of the graph, the vertex of the transformed function is at (4, 7). Therefore, there has been a translation of:
4 units right7 units up[tex]\implies f(x-4)+7=|x-4|+7[/tex]
From inspection of the graph, we can see that it has been stretched parallel to the y-axis:
[tex]\implies a\:f(x-4)+7=a|x-4|+7[/tex]
The line goes through point (0, 9)
Substituting this point into the above equation to find [tex]a[/tex]:
[tex]\implies a|0-4|+7=9[/tex]
[tex]\implies 4a=2[/tex]
[tex]\implies a= \dfrac{1}{2}[/tex]
Therefore,
[tex]\implies g(x)=\dfrac{1}{2}|x-4|+7[/tex]

Solve the simultaneous equations
4x + 3y = 21
and
4x + 2y = 16
Answer:
x= 1.5
y=5
Step-by-step explanation:
do equation 1 and 2 then,
subtract the equation
find the value of y by subtracting
and put the value of y in any equation and get the value of x
Step-by-step explanation:
4x+3y=21
4x+2y=16
If we add both the equation:
4x + 3y = 21
4x + 2y = 16
(-) (-) (-)
4x + 3y = 21
-4x - 2y= -16
=> 0+1y= 5
y=5
substituting Y in eq 1
4x+3y=21
4x+3(5)=21
4x+15=21

Please i really need help, i really need this i will give a brainliest to the people that answer correctly
Answer:
Step-by-step explanation:
so to go forward we input x and get out y, to go backwards ( the inverse) we plug in y and get out x , so just solve the equation for x
f(x) = 8x - 5
remember that f(x) = y
so,
y = 8x - 5
now solve for x
y+5 = 8x
(y+5) / 8 = x
then remember that we want to swap x and y ,
(x+5) / 8 = y
now y = [tex]f^{-1}[/tex](x), it's kinda confusing.
[tex]f^{-1}[/tex](x)= [tex]\frac{x+5}{8}[/tex]
Can any one please help me under this? I need to know which option indicates that 3 goes after 5and between 7,12and 5 then how that goes before 12 and between7 and 3. I’ve been reading this forever and I don’t understand her wording. Help please! Ayuda porfavor!
"3 va después de 5 y entre 7 y 12" = "3 goes after 5, and between 7 and 12"
This eliminates A and D (3 is not between 7 and 12 in either choice).
"5 va antes de 12 y entre 7 y 3" = "5 goes after 12, and between 7 and 3"
This eliminates C (5 is not between 7 and 3).
So the correct sequence is B.
Find the value of x if the area of the trapezoid is 54.
Answer:
11
Step-by-step explanation:
area = (side a + side b)/2 times height
side a = (2 times (area ÷ height)) - side b
side a = (2 times (54+6)) - 7
side a = (2 times (9)) - 7
side a = 18 - 7
side a = 11

to get c or the hypotenuse

Given
m
∥
n
m∥n, find the value of x and y.
If m is parallel to n then value of x and y is X = 41° and Y = 41°.
What are Angles?An angle is formed when two straight lines or rays meet at a common endpoint.
Given that line m and n are parallel lines.
Parallel lines are those straight lines that are always the same distance apart from each other.
As y is vertically opposite to the angle 41° . So the value of y is also 41° and angle x is equal to angle y because they are alternate angles. So the value of y is also 41°.
Therefore X = 41° and Y = 41°.

How do we write 8x-2y=10 in slope intercept form?
[tex]\blue\textsf{\textbf{\underline{\underline{Answer and Solution:-}}}}[/tex]
First subtract 8x on both sides:-
-2y=10-8x
or
-2y=-8x+10
Now divide by -2 on both sides:-
y=2x-5
This is our equation in slope intercept form.
Good luck.

7. The cost, c(x), for a carriage ride is given by c(x) = 2x + 4, where “x” is the number of minutes. Graph c(x), including the correct axis labels.
As m is a constant that is applied to x, it has to have something to do with minutes, eliminating A and B. As the constant is 2, it has to have something to with 2, eliminating D, meaning your answer is C. This is because a slope is the rate of change of y in relation to x, so it would be rate of change of y is a (a being your constant, in this case 2) per x. With your case, y is cost and x is minutes, leading to answer choice C.

x+2=43
check your answer by adding the three integers:
41+42+43=126
Answer:
40, 42 and 44Step-by-step explanation:
An Integer is even, if it's divisible by two. it's also a multiple of two.let first integer= Y note : Y is an even number.
second integer= (Y+2)
third integer = (Y+4)
from the question,
Y+Y+2+Y+4= 126
3Y+6 = 126
3Y = 126-6
3Y = 120
dividingbothsides by (3)
3Y/3 = 120/3
Y= 40
therefore, the even integers are:
40
(Y+2)= 40+2= 42
(Y+4) =40+4= 44
