Find the value of x in the diagram below.
Answer:
x = 31
Step-by-step explanation:
The 2 sides are congruent, meaning the 2 angles are equal so:
47 = x + 16
subtract 16 from both sides
31 = x

ahmad drove 756 miles in 12 hours, at the same rate how many miles would he drive in 7 hours?
Find his rate by dividing total miles by hours:
756 miles / 12 hours = 63 miles per hour.
Multiply the rate by number of hours:
63 x 7 = 441 miles
Answer:
441 miles
Step-by-step explanation:
756 deived by 12 = 63x7 =
441 miles
What is the value of the expression 6 3/4 ( -11.5)?
Answer:
I'm assuming your problem looks like this: 4+5*6-3 =? To solve this problem you need to use the order of operations. PEMDAS which stands for Parentheses, exponents, multiply and divide, and lastly add and subtract. You must multiply and divide before you add and subtract so you must do 5*6 first. You now get 4+30-3. Now all you have left is addition and subtraction so you now just go from right to left and do one at a time. So 4+30 = 34 , 34-3=31. Therefore your answer should be 31. Hope that helped!

Hello!
[tex]\large\boxed{f^{-1} = \frac{5x+2}{4x-2}, f^{-1}(3) = \frac{17}{10} }[/tex]
[tex]f(x) = \frac{2x +2}{4x - 5}[/tex]
Find the inverse by swapping the x and y variables:
[tex]y = \frac{2x +2}{4x - 5}\\\\x = \frac{2y +2}{4y - 5}[/tex]
Begin simplifying. Multiply both sides by 4y - 5:
[tex]x(4y - 5) = 2y + 2[/tex]
Start isolating for y by subtracting 2 from both sides:
[tex]x(4y - 5) -2 = 2y[/tex]
Distribute x:
[tex]4yx - 5x - 2 = 2y[/tex]
Move the term involving y (4yx) over to the other side:
[tex]- 5x - 2 = 2y - 4yx\\\\[/tex]
Factor out y and divide:
[tex]- 5x - 2 = y(2 - 4x)\\\\y = \frac{-5x-2}{-4x+2} \\\\y = \frac{-(5x + 2)}{-(4x - 2)} \\\\y^{-1} = \frac{5x + 2}{4x - 2}[/tex]
Use this equation to evaluate [tex]f^{-1}(3)[/tex]
[tex]f^{-1}(3) = \frac{5(3) + 2}{4(3) - 2} = \frac{17}{10}[/tex]

The lines graphed below are perpendicular. The slope of the red line is 4 what is the slope of the green line
m=
Answer:
m=-1/4
Step-by-step explanation:
Perpendicular lines are negative reciprocals.
So if you have a slope of m= 4x you can break it up into, two parts
m= -4x
this is the negative^
and the reciprocal of m= -4x is m= -1/4x
The slope of the green line if the lines are perpendicular would be -1/4.
How to find if two lines are perpendicular to each other?If two lines are perpendicular to each other, then their slopes are negative reciprocal of each other.
That means, if one line's slope is 'a', then its perpendicular line's slope would be -1/a.
Slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.
For the two lines two be perpendicular, the product of their slope must be -1.
Let the slope of the red and green line be m1 and m2.
Given the following
The Slope of red line = 4
According the definition, we get,
4m2 = -1
m2 = -1/4
Hence, the slope of the green line if the lines are perpendicular is -1/4

HELP PLEASE ITS Which point would not be a solution to the system of linear inequalities shown below? y -3x+7!
(5,−5)(10,−8)(5,−6)(−10,−7)
Answer:
(-10,-7)
Step-by-step explanation:
Lets start with the equation y>-3x+7
Which of these are solutions?
(5,-5) - yes
(10,-8) - yes
(5,-6) - yes
(-10,-7) - no
Now lets do the equation y<4/5x-2
Which of these are solutions?
(5,-5) - yes
(10,-8) - yes
(5,-6) - yes
(-10,-7) - no
So, the point (-10,-7) is not a solution to the system of equations.
Graph the following system of equation
y= 3x + 11
y= -4x + 4
Answer:
Step-by-step explanation:
Answer:
These equations describe two lines that intersect at the point (-1, 8), one of them with a slope of 3, the other with a slope of -4.
Step-by-step explanation:
We can find the point where these two lines intersect by taking one of the equations, solving it for x, and substituting it into the other equation.
[tex]y = -4x + 4\\-4x = y - 4\\4x = 4 - y\\x = 1 - \frac{y}{4} \\\\y = 3x + 11\\y = 3(1 - \frac{y}{4}) + 11\\y = 3 - \frac{3y}{4} + 11\\y + \frac{3y}{4} = 3 + 11\\\frac{4y}{4} + \frac{3y}{4} = 14\\\frac{7y}{4} = 14\\y = \frac{4}{7} * 14\\y = 4 * \frac{14}{7}\\y = 4 * 2\\y = 8[/tex]
Now we can plug that into our first equation to find x
[tex]x = 1 - \frac{y}[4}\\x = 1 - \frac{8}[4}\\\\x = 1 - 2\\x = -1[/tex]
So these lines intersect at the point (-1, 8), one of them with a slope of 3, the other with a slope of -4

In the figure below, ray KM is the angle bisector of ZLKJ. If MZLKJ = 82",
what is MZMKJ?
Answer:
41º
Step-by-step explanation:
An angle bisector splits an angle in half. So angle LKM+angle MKJ=angle LKJ. We know angle LKJ=82º, so angle LKM=angle MKJ=82º/2=41º.
