2x - 3y = 6
Find the x and y Intercepts
Answer:
x-intercept(s): (3,0)
y-intercept(s): (0,−2)
Step-by-step explanation:
Answer:
x=3 and y=-2
Step-by-step explanation:
2x - 3y = 6
cancel out the y
2x - 3(0) = 6
2x = 6
divide both sides by 2
x = 3
2x - 3y = 6
cancel out the x
2(0) - 3y = 6
-3y = 6
divide both sides by -3
y = -2

Find the measure of <1
Consider the triangle (in which angle4 is present)
by angle sum property,
20 + 40 + angle4 = 180
60 + angle4 = 180
angle4 = 180 - 60
angle4 = 120
Also,
angle2 = 120 (vertically opposite angles)
angle1 + angle2 = 180 (linear pair)
angle1 + 120 = 180
angle1 = 180 - 120
angle1 = 60
can anyone help me with this?
Write True or False and then explain. The angle of depression is the same degree measure as the angle of elevation in a diagram.
Answer:
The term angle of elevation denotes the angle from the horizontal upward to an object. An observer's line of sight would be above the horizontal. The term angle of depression denotes the angle from the horizontal downward to an object. ... Note that the angle of elevation and the angle of depression are congruent .

Harper is making pudding cups for a big celebration. She made 5 pounds of pudding, but she needs to separate the pudding into individual 4-ounce cups. How many total individual pudding cups can Harper make?
Given :
Total amount of pudding made, T = 5 pounds.
Size of each cup, s = 4 ounces.
To Find :
How many total individual pudding cups can Harper make.
Solution :
Let, n number of pudding cups can filled with 5 pounds pudding.
We know, 1 pound = 16 ounces.
So, 5 pounds = 16×5 = 80 ounces.
Now,
[tex]n = \dfrac{80}{s}\\\\n = \dfrac{80}{4}\\\\n = 20 \ cups[/tex]
Therefore, 20 cups can be filled with 5 pounds of pudding.

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]
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.

you flip a coin twice what is the probability of getting tails then getting heads
HELP ASAP
Answer: The odds of getting tails twice in a row are 1/2 * 1/2 = 1/4. So 25% of the time you'll get heads twice in a row. But, if you've already flipped a coin 99 times, and gotten heads each time, then the odds of your next flip being heads is still just 50:50.
Step-by-step explanation:
Verizon offers a cell phone plan where customers buy a cell phone for $300 and pay a monthly fee of $40. T- Mobile offers a cell phone plan where customers buy a cell phone for $200 and a monthly rent of $60. Write the equation needed to find the number of months a customer would have to own a cell phone in order for the two cell phone companies to be equal. PLEASE ANSWER QUICKLY. need help!!!
Answer:
A customer would have to own a cell phone for 5 months in order for the two companies to be equal.
Step-by-step explanation:
Given that:
Cost of cell phone at Verizon = $300
Monthly fee = $40
Let,
x be the number of months
V(x) = 40x + 300
Cost of cell phone at T-mobile = $200
Monthly fee = $60
T(x) = 60x + 200
For equal amount of money,
V(x) = T(x)
40x+300=60x+200
300-200=60x-40x
100=20x
20x=100
Dividing both sides by 20
[tex]\frac{20x}{20}=\frac{100}{20}\\x=5[/tex]
Hence,
A customer would have to own a cell phone for 5 months in order for the two companies to be equal.
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.
