Answer:
36x+42 if you need it simplified
x=-7/6 if you set the equation equal to zero
Answer:
42+36w
Step-by-step explanation:
6(3w+5)+6(3w+2)?
18w+30+6(3w+2)?
18w+30+18w+12?
Combine like terms: 18w,18w and 30,12.
30+12=42

Noah and Lin are marketing paper cones to hold popcorn to hand out at parent math night. They want the cones to hold 9 cubic inches of popcorn. What are two different possible values for height h and radius r for the cones?
if h=3, then r=
if r=2, then h=
Answer: r = 1.69 inches
h = 2.15 inches
Step-by-step explanation: Volume of a solid is the amount of space contained within a solid.
Volume of a cone is directly proportional to radius and height:
[tex]V=\frac{1}{3}\pi r^{2}h[/tex]
They want the cones to hold the same volume of 9 cubic inches.
If height is 3:
[tex]9=\frac{1}{3}\pi r^{2}3[/tex]
[tex]\pi r^{2}=9[/tex]
[tex]r^{2}=2.864[/tex]
r = 1.69 inches
When height is 3, radius is 1.69 inches for a cone to have 9 cubic inches of volume.
If radius is 2:
[tex]9=\frac{1}{3}\pi (2)^{2}h[/tex]
[tex]h=\frac{9(3)}{4 \pi}[/tex]
h = 2.15 inches
If radius is 2 inches, height of the cone is 2.15 inches.

in triangle ABC with vertices A(4,5),B(-2,1) and C(0,3),E and F are midpoints of sides AB and AC resp . then, find coordinates of E and F
Answer:
The answer is
E=(1, 3)
F=(2,4)
Step-by-step explanation:
When E is midpoint of AB
Then
[tex]e = ( \frac{4 + ( - 2)}{2} . \frac{5 + 1}{2} ) \\ = (1.3)[/tex]
By this way we can find F
[tex]f = ( \frac{4 + 0}{2} . \frac{5 + 3}{2} ) \\ = (2.4)[/tex]

0=1-2y+14x what is the slope and the y-intercept
Answer:
slope: 7
y-intercept: 1/2
Step-by-step explanation:
Put it into the form y = mx + b where m is the slope and b will be the y-intercept. (For example, in the equation y = 3x + 2 the slope is 3 and the y-intercept is 2).
[tex]0=1-2y+14x\\2y=1+14x\\2y = 14x+ 1\\y = 7x + 1/2[/tex]
So you know that m = 7, so the slope is 7
and
b = 1/2, so the y-intercept is 1/2.

You measure 3 inches between your house and the movie theater. How many miles is in from your house to the movie theater?
Answer:
4.734 * 10^-5 miles
Step-by-step explanation:
Given that:
Distance between House to movie theater = 3 inches
Expressing the distance in miles :
Converting inch to miles
1 inch = 1.578 * 10^-5 miles
3 inches = (3 * 1.578*10^-5)
3 inches = 4.734 * 10^-5 miles

Which correctly explains the number of solutions of the following system of linear
equations?
- 3x + 3y = 12
y = x + 4
А The graphs of the equations are parallel lines because they have the same slope
but different y-intercepts. The system has no solution.
B The graphs of the equations are lines that intersect at one point because the
equations have the same slope but different y-intercepts. The system has
exactly one solution.
с
The graphs of the equations are lines that intersect at one point because the
equations have the same slope and same y-intercept. The system has exactly
one solution.
D The graphs of the equations are the same line because the equations have the
same slope and same y-intercept. The system has infinitely many solutions.
Answer:
D I dont know if im right though
Step-by-step explanation:
The system of equations are same and graphs of the equations are the same line because the equations have the same slope and same y-intercept. The system has infinitely many solutions.
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
The first equation is -3x + 3y = 12 be equation (1)
y = x + 4 be equation (2)
Adding 3x on both sides , we get
3y = 3x + 12
Divide by 3 on both sides , we get
y = x + 4 be equation (3)
So , the equation ( 2 ) is same as equation ( 3 )
Now , the slope of the equation is m = 1 and the y intercept is b = 4
Hence , the equations have infinite solutions
