We know the equation.
=> y = mx + bWe also know the y-intercept is -1.
=> y = mx - 1All we need to do now is to find the slope. We know the slope formula.
=> Rise/Run = Slope=> 4/6 = Slope=> 2/3 = SlopeConclusion:Therefore, our equation is y = 2x/3 - 1

Which quadratic equation is equivalent to (x + 2)2 + 5(x + 2) – 6 = 0?
(u + 2)2 + 5(u + 2) – 6 = 0 where u = (x – 2)
u2 + 4 + 5u – 6 = 0 where u = (x – 2)
u2 + 5u – 6 = 0 where u = (x + 2)
u2 + u – 6 = 0 where u = (x + 2)
Answer:
we have
(x+2)^{2} +5(x+2)-6=0(x+2)
2
+5(x+2)−6=0
Let
u=(x+2)u=(x+2)
Substitute in the expression
(u)^{2} +5(u)-6=0(u)
2
+5(u)−6=0
therefore
the answer is
(u)^{2} +5(u)-6=0(u)
2
+5(u)−6=0 is equivalent to (x+2)^{2} +5(x+2)-6=0(x+2)
2
+5(x+2)−6=0

Answer:
-32r+3
Step-by-step explanation:
You have to combine -9r+2r-5r-20r, orrrr…
you can remove the variables and solve:
[tex]-9+2-5-20=\\ -32[/tex]
then add the variable back,
[tex]-32r[/tex]
since the +3 has no variable, you can’t add it to -32r

Which expression is equivalent to the following complex fraction? 2 minus StartFraction 1 Over y EndFraction divided by 3 StartFraction 1 Over y EndFraction.
The equivalent fraction to the given complex fraction is [tex]\frac{2y-1}{3y+1}[/tex].
Given expression,
[tex]\dfrac{2-\frac{1}{y} }{3+\frac{1}{y} } } \\[/tex]
We have to find the equivalent fraction of [tex]\frac{2-\frac{1}{y} }{3+\frac{1}{y} } } \\[/tex] .
On solving,
[tex]\dfrac{2-\frac{1}{y} }{3+\frac{1}{y} } } =\dfrac{\frac{2y-1}{y} }{\frac{3y+1}{y} }[/tex]
Eliminating y from numerator and denominator we get,
[tex]\dfrac{2-\frac{1}{y} }{3+\frac{1}{y} } } =\dfrac{2y-1} {3y+1} }[/tex]
Hence the required expression is [tex]\frac{2y-1}{3y+1}[/tex].

can you guys help me?
Answer:
Step-by-step explanation:
1. y = 2x
y = 2*4 = 8 Checks, therefore
y = 20 for x = 10
2. y = 3x
y = 3*(0.3) = 0.9 Checks, therefore:
y = 3*(1.5) = 4.5
y = 3*
3. y = 5/x
y = 5/(1/2) = 10 Checks, therefore:
3 = 5/x
x = 5/3
4 v = wu
7*3 = 21 Checks, therefore:
v = (3/4)*(6) = (18/4) = (9/2)
v = (2/3)wu
v = (2/3)*7*3 = 14 Checks
5 m = Kn/p [Add the K as a constant that will make m = Knp true at some value of K]

Answer:
8 sides.
Step-by-step explanation:
The sum of each of the interior and exterior angles = 180 degrees.
Therefore as the ratio is 1:3 the exterior angles are all = 1/4 * 180
= 45 degrees.
So the number of sides = 360/45 = 8. ( As the sum of the exterior angles in all polygons = 360 degrees).

1/3 times 3/4 times 1/3 as a fraction so basically what is 0.08333333333 as a fraction
Answer:
mark me brainliest
Step-by-step explanation:
To write 0.08333333333 as a fraction you have to write 0.08333333333 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
0.08333333333 = 0.08333333333/1 = 0.8333333333/10 = 8.333333333/100 = 83.33333333/1000 = 833.3333333/10000 = 8333.333333/100000 = 83333.33333/1000000 = 833333.3333/10000000 = 8333333.333/100000000 = 83333333.33/1000000000 = 833333333.3/10000000000 = 8333333333/100000000000

It is 8 a.m. and the animals are waking up. In exactly 5 minutes. Sarah will chirp. Sarah will then chirp every 5 minutes until 10 a.m.! To make matters worse, in exactly 13 minutes, Alex will chirp. Alex will then chirp every 13 minutes until 10 a.m.! How many times will both of them be making noise at exactly the same time? Explain how you solved it
Answer:
Once.
Step-by-step explanation:
To find when they chirp together, we must find the LCM of the two numbers. The LCM, or least common multiple of 13 and 5 is 65. Therefore, after 65 minutes is the first time they chirp together. Then we can multiply 65 by 2 to see if they chirp a second time. 65x2 is 130, but 8AM-10AM is only 120 minutes, therefore they do not chirp together more than 1 time.

65÷x = 13/2 ×5
65÷x = 65÷2
x = 2
so 2 is answer

2
let the unknown number be x
65/x=6+1/2*5
65/x=13/2*5
65/x=65/2
65/x=32.5

1/2 mile in 1/16 an hour.what is its rate in miles per hour
Answer:
Step-by-step explanation:
Miles per hour is a speed and we usually just hear the number of how fast a car or a rocket or meteor is going. We look at our speedometer in the car and see how fast we're driving, 35mph or 73mph
But it is literally a formula. Miles on top and hours on the bottom, like a fraction. If the numbers you're given are in miles and in hours, your can just fill in the numbers and simplify.
Your numbers are also fractions, so it looks a little scary, but no worries, you can simplify it.
You have 1/2 on top and 1/16 on the bottom. A fraction bar is just a division sign, we're going to divide 1/2 ÷ 1/16 We do this by using the rule:
Keep Change Flip
1/2 Keep
___ Change
1/16 Flip
Keep the 1/2
Change ÷ to *
Flip the 1/16
So it becomes 1/2* 16/1
1/2 * 16 is 8
8 miles per hour is your answer.
If fractions are too terrifying, you could just change 1/2 to .5 and
change 1/16 to .0625
.5 ÷ .0625= 8
Answer: 8mph
