Answer:
[tex]y = \frac{7}{6} x[/tex]
Step-by-step explanation:
Slope-intercept form is
[tex]y = mx + b[/tex]
Where m = slope,
and b = y-intercept.
The problem states that the slope is [tex]\frac{7}{6}[/tex], and it also states that one point on the line is the origin. (0, 0)
Because the origin crosses the y-axis at point 0, we know that the y-intercept is 0.
All that's left to do is plug these values into the slope formula.
[tex]y = \frac{7}{6} x + 0[/tex]
We can then simplify the equation even more.
[tex]y = \frac{7}{6} x[/tex]

I need help on this and the first person who answer correctly gets a BRANILIST
Answer:
first you need to set up the equation which is 20+2x=44 then isolate 2x by doing the inverse operation for 20 which is -20 and add them to both sides which would now give you 2x=24 so divde 24 by 2 which is 12, x=12 answer 12ml

Step-by-step explanation:
We presume the first transformation is a translation 4 units right and 1 unit up:
(x, y) ⇒ (x+4, y+1)
The second transformation negates the x-coordinate, so the two transformations together have the rule ...
(x, y) ⇒ (-(x+4), y+1)
Then the transformed points are ...

Work out the following (+35) + (-33)
Answer:
2
Step-by-step explanation:
so (+35) can be written as 35 because it's automatically already positive. +(-33) can be written as -33 because of one negative sign and one positive sign (if it was two negative or two positive, it would be positive). it's the same as 35-33, and 35-33=2.
Answer:
(+35) + (-33)
⇒ 35-33
⇒2

There are two questions :v
Answer:
Step-by-step explanation:
One
v^2 - 16
This formation is called the difference of squares. That's because there are 2 squares v^2 and 16. The key to this question is the minus sign.
The square root of v^2 = v
The square root of 16 = 4
You get (v + 4)(v - 4)
Let's see what happens when you expand it.
v*v = v^2v*(-4) = - 4vv*(4) = 4v4*-4 = - 16Look what happens when you add these 4 terms together.
v^2 - 4v + 4v - 16v^2 - 16is what is left. The two middle terms cancel out.
Two
This one is a perfect square
w^2 + 16w + 64
(w + 8)(w + 8)
Notice both factors are the same. You might wonder how I new that.
w^2 is a perfect square so take the square root. .... v
64 is a perfect square so take the square root ..... 8
Now you have to work backwards to see if it is right.
w*w = w^2w*8 = 8w8*w = 8w8^2 = 64Adding you get w^2 + 16w + 64 which is what you started with.

A fair coin was flipped 50 times. It landed on heads 29 times.
What is the experimental probability that the coin landed on tails?
Answer:
21/50, 42%
Step-by-step explanation:
The total times the coin was flipped is 50 and the number of times it landed on tails is 50-29=21. So we need to divide 21 by 50, which gives us 42%.
Find the area of the shaded region. Use 3.14 for pi.
Answer:
326
Step-by-step explanation:
First you find the area of the triangles. Since squares have equal sides we know that the triangle has a side of 20 and 12. We plug this information into the formula A=20x12/2 which equal 120 but since we have 2 triangles we multiply by 2 and get 240. Then we find the area of the square which is 400 when you multiply 20x20. Then you find the area of the circle which is 3.14x10^2 which equals 314. You add 240 and 400 to get 640. You subtract 460 from 314 and get 326.
gimme the answer for 10 points :)
Given:
The table of values.
v and x are in direct proportion.
To find:
The formula connecting v and x.
Solution:
(a)
v and x are in direct proportion.
[tex]v\propto x[/tex]
[tex]v=kx[/tex] ...(i)
Where, k is the constant of proportionality.
Putting v=13.6 and x=32.64, we get
[tex]13.6=k(32.64)[/tex]
[tex]\dfrac{13.6}{32.64}=k[/tex]
[tex]\dfrac{5}{12}=k[/tex]
Putting the value of k in (i), we get
[tex]v=\dfrac{5}{12}x[/tex]
Therefore, the required formula that connecting v and x is [tex]v=\dfrac{5}{12}x[/tex].
(b)
Putting v=n and x=8.16, we get
[tex]n=\dfrac{5}{12}(8.16)[/tex]
[tex]n=3.4[/tex]
Therefore, the value of n is 3.4.
In triangle EFG, angle E equals 8x-16, angle F equals x+8, and angle G equals 2x-10. What is the value of x?
Answer: The value of x= 18
Step-by-step explanation:
Given: In triangle EFG, angle E equals 8x-16, angle F equals x+8, and angle G equals 2x-10.
The sum of all angles of a triangle is 180°.
Therefore, in triangle EFG
∠E + ∠F +∠G= 180°
⇒ 8x-16 +x+8+ 2x-10 = 180
⇒ 11x-18= 180
⇒ 11x = 180+18
⇒11x=198
⇒ x= 18 [Divide both sides by 11]
Hence, the value of x= 18

43.8% complete This is a Single Choice Question; skip ahead to question content A B C D E Confirm To order the right amount of flooring, you need to know the floor area of the living room shown below. What is that area, in square feet?
Answer: 180 ft²
Step-by-step explanation:
The rest of the question is:
The living room is 18 feet wide and 10 feet long.
The floor seems to take the shape of a rectangle because it has one dimension being longer than the other.
As this is a rectangle, the floor area will be calculated by the formula:
= Length * Width
= 10 * 18
= 180 ft²
