6 = 2(y +2)
What does y equal
Answer:
One
Step-by-step explanation:
6=2(y+2)
Distribute 2
6=2y+4
-4 -4
2=2y
______
2
y=1
Answer:
y = 1
Step-by-step explanation:
First, you need to use the distributive property to simplify:
6 = 2y + 4
Then, subtract 4 from both sides, so you get the numbers on one side and the variables on the other.
2 = 2y
Divide both sides by 2, and . . .
y = 1

Step-by-step explanation:
The first 12 seconds of a rollercoaster ride can be modeled by a polynomial function where t is the number of
seconds and h(t) is equal to the height of the roller coaster in feet. Some roller coasters go underground as well
as above ground. In factored form, the rollercoaster can be modeled by the function
2
h(t)=2/5 (t - 1) (t-1) (t - 9) (t - 11)
What key feature(s) can be easily identified from the factored form? Explain how each key feature is related to
the rollercoaster. Use specific values in your explanation.

4v = 20
Help please
Answer:
v=5
Step-by-step explanation:
you are trying to make 4v into v right ?
so simply divide it by 4 - the same if it was 4a or 7a or 9k, always start by dividing by the number
then you need to balance the two sides - so whatever number you divide the letter by (which is the 4 in this case) , you do the same with the other side , so whatever number is after the equal sign , divide it by 4
PART ONE ↓ 4v = 20
DIVIDE BY 4 → v = 20
PART TWO v = 20 ↓
v = 5 ← DIVIDE BY 4
Solve for x

45°
Answer:
x = 109
Step-by-step explanation:
64 + 45 = 109
180 - 109 = 71
180 - 71 = 109
8 squared by 6 ÷ 4 squared by 3 =
8^6 ÷ 4^3
8^6 = 262,144
4^3 = 64
So, 262,144 ÷ 64 = 4,096.
Done!
Answer:
2^12 = 4096
Step-by-step explanation:
Assuming that the problem is:
8^(6) / 4^(3)
1. Convert all numbers to the same base
In other words, rewrite the problem such that all the bases (the numbers under the exponent) are the same.
8 can be rewritten as 2^3
4 can be rewritten as 2^2
Hence the problem is:
((2^(3))^(6)) / ((2^(2))^(3))
2. Combine the exponents on the numerator and denominator
((2^(3))^(6)) / ((2^(2))^(3))
Simplify, remember an exponent to the power of another exponent is the same as multiplying the two exponents, applying this:
(2^(18)) / (2^(6))
3. Simplify the fraction and solve
(2^(18)) / (2^(6))
Dividing two exponents, with the same base is the same as subtracting the exponents, hence:
(2^(12))
= 4096

How long will this trip take? A bike 15 miles per hour on a biking trail to a trailhead 30 miles away.
Answer:
2 hours
Step-by-step explanation:
Distance = Rate * Time
If we replace these with the numbers in the problem and use "t" as the variable, it becomes:
30 miles = 15 mph * t
Now, to solve:
30 = 15t
divide both sides by 15
t = 2
add the units
time = 2 hours

casts a shadow 12ft long. What is the height of the tree? Explain or show all work.
Answer:
28 ft
Step-by-step explanation:
Since the shadows were cast at the same time of the day, both triangular images formed would be similar to each other.
Therefore, the ratio of their corresponding sides would be equal.
That is, the height of the tree / the height of the alien = the shadow of the tree / the shadow of the alien
Height of the tree = x ft
Height of the alien = 7 ft
Shadow of the tree = 48 ft
Shadow of the alien = 12 ft
Plug in the values into the proportional equation stated earlier.
Thus, the ratio of their corresponding sides would be:
[tex] \frac{x}{7} = \frac{48}{12} [/tex]
Cross multiply
[tex] x*12 = 48*7 [/tex]
[tex] 12x = 336 [/tex]
Divide both sides by 12
[tex] x = \frac{336}{12} [/tex]
[tex] x = 28 [/tex]
The height of the tree = 28 ft

3. PQR is an isosceles triangle with PQ = PR, and angle QPR = x".

(a) Find an expression for the perimeter of the triangle in terms of r, giving
your answer in its simplest form.
(b) Work out the value of r, if the perimeter is 49 cm.
Answer:
a). Perimeter = (5r + 9) cm
b). r = 8
Step-by-step explanation:
Property of isosceles triangle:
- Two sides of an isosceles triangle are equal.
- Opposite sides of the equal angles are equal in measure.
From the figure attached,
PQ = QR = (2r + 3)
a). Since perimeter of a polygon = sum of all sides of the polygon
= PQ + QR + PR
= (2r + 3) + (2r + 3) + (r + 3)
= 5r + 9
Perimeter of the given triangle = (5r + 9) cm
b). Perimeter of the given triangle = 49 cm
(5r + 9) = 49
5r = 40
r = 8
Pls help i only have 30 mins left
Answer:
d=rt is basically y=mx+b but with different variables. B is where the line intercepts the y axis and since this line intercepts at 0, 0 b can automatically be deleted from the equation. therefore d=rt is equivilent to y=mx
The slope is 6. I know this by looking at the first point of the line (0, 0) and finding the next point on the line (1, 6). To get from 0, 0 to 1,6 you need to go up 6 and over 1. Since rise/run is the slope of a line 6/1 or 6 is the slope.
At 1, 6 we see that in 1 hour, joseph went 6 miles. Therefore the constant rate is 6 miles per hour (6 mp/h.)
The slope, already found, is 6 and therefore if d=rt is equivilent to y=mx we can write our equation as d=6t
6 mp/h
d=6t

Answer:
2Step-by-step explanation:
The slope of a line given two points can be found by using the formula

Y=(m-2)(m-4)
Find the Y intercept
Please help!!!
Answer:
y - intercept = 8
Step-by-step explanation:
Given
y = (m - 2)(m - 4)
To find the y- intercept, let m = 0 in the equation and solve for y, that is
y = (0 - 2)(0 - 4)
= (- 2)(- 4)
= 8 ← y- intercept or in coordinate form as (0, 8 )

Solve five ninths minus two sixths equals blank.
twelve fifty fourths
twenty fifty fourths
six thirds
three over one
The result of five ninths minus two sixths is two - ninths.
Let us first write the words in figures so that we can perform the required calculation;
five ninths = 5/9
two sixths = 2/6
This means that we are simply asked to subtract 5/9 from 2/6
Hence;
5/9 - 2/6, we have to take LCM. The LCM of 5/9 and 2/6 is 18. The term LCM actually means lowest common multiple of 9 and 6.
So;
[tex]\frac{10 - 6}{18} = \frac{4}{18} = \frac{2}{9}[/tex]
