What is the slope of the line?
Answer:
the slope is -2
Step-by-step explanation:
When using rise over run you must divide the Y (in this case it's 2) by the X (which is 1), and in this problem 2 divided by 1 equals 2, but it's a negative line because it's going down which means your answer is -2

Answer:
[tex]y=\frac{9\sqrt{3} }{2}[/tex] or 7.79 x= 9/2 or 4.5
explanation:
This is a special right triangle; a 90-60-30 triangle.
The side labelled y = a, side labelled x is equal to [tex]a\sqrt{3}[/tex], and the hypotenuse equals 2a.
First solve for a. [tex]9\sqrt{3}=2a[/tex] [tex]a=\frac{9\sqrt{3} }{2} =y[/tex] and that gives you y.
Then use a to find x. [tex]a\sqrt{3} =x[/tex] so [tex]\frac{9\sqrt{3} }{2} *\sqrt{3} = 9/2=4.5[/tex]
1/2x-7=1/3(x-12) can someone please help me I have a math test dueeee
Answer:
The correct answer is,
[tex]x = 18[/tex]
Answer:
x = 18
Step-by-step explanation:
So first you want to get rid of the fractions, which are 1/2 and 1/3. To do this you can multiply both sides of the equation by 6, so you would get:
3x - 42 = 2(x - 12).
Next, on the right side of the equation you can distribute the 2.
3x - 42 = 2x - 24
You want to get all the x variables on one side so you can subtract 2x from both sides.
x - 42 = -24
And finally you add 42 to both sides
x = 18

Answer:
135°
Step-by-step explanation:
The sum of interior angles in this rectangle is equal to 720
Two of the angles are right (has 90°)
so 4x + 180 = 720 subtract 180 from both sides
4x = 540 divide both sides by 4
x = 135°

Determine the intercepts of the line.
y + 5 = 2(x+1)
y-intercept:
X-intercept:
Answer:
Y intercept: -3
X intercept: 1.5
Step-by-step explanation:
Find the y intercept by setting x equal to 0 and solving for y:
y + 5 = 2(x + 1)
y + 5 = 2(0 + 1)
y + 5 = 2(1)
y + 5 = 2
y = -3
Find the x intercept by setting y equal to 0 and solving for x:
y + 5 = 2(x + 1)
0 + 5 = 2(x + 1)
5 = 2(x + 1)
5 = 2x + 2
3 = 2x
1.5 = x
So, the y intercept is -3 and the x intercept is 1.5

Mrs. Sanders can clean the windows of her house in
3 hours. Her daughter can clean the windows in 6 hours.
How long will it take them to clean the windows if they
work together?
9514 1404 393
Answer:
2 hours
Step-by-step explanation:
Mrs. Sanders cleans 1/3 of the windows per hour. Her daughter cleans 1/6 of the windows per hour. Working together, they clean 1/3 +1/6 = 1/2 of the windows per hour.
It will take them 2 hours to finish when they work together.
