i cant see the answers does anyone else have this problem

Answer:

D

Step-by-step explanation:

The diagonals of a parallelogram bisect each other, thus

DE = BE , substitute values

4y - 8 = y + 10 ( subtract y from both sides )

3y - 8 = 10 ( add 8 to both sides )

3y = 18 ( divide both sides by 3 )

y = 6

Thus

BD = y + 10 + 4y - 8 = 5y + 2 = 5(6) + 2 = 30 + 2 = 32 → D

Answer:

a. -17 -9n

Step-by-step explanation:

Question written clearly below:

Which answer choice is equivalent to the expression below?

-7(2+n)+1/3(-9-6n)

a.-17 -9n

b, -14-12n

c. 11+5n

d. 14+2n

Solution

-7(2+n)+1/3(-9-6n)

Open parenthesis

(-14-7n)+(-9/3-6/3n)

= -14-7n+(-3-2n)

= -14-7n-3-2n

Collect like terms

= -14-3-7n-2n

= -17-9n

The answer is option a. -17 -9n

Answer:

115.96

Step-by-step explanation:

=> [tex]9393 / 81 * 1[/tex]

By BODMAS, Dividing first

=> 115.96 * 1

Now, Multiplying

=> 115.96

Answer:

115.962963

Step-by-step explanation:

81 x 1 = 81

9393 ÷ 81 = 115.96

Answer: The third graph (the one on the right side)

Step-by-step explanation:

The inequalities are:

2x -3y ≤ 12

y < -3

First, for the second inequality, we can see that y must be strictly less than -3, so we should see a dotted line at y = 3, and a shaded section under that line.

From this, we can discard the second graph (the middle one).

The first inequality can be rewritten as:

2x - 3y ≤ 12

-3y ≤ 12 - 2x

Now we divide by -3 on both sides, as we are dividing by a negative number, the direction of the ≤ sign changes:

y ≥ (12/-3) + (-2/-3)x = -4 + (2/3)*x

This means that the shaded section must be above the line:

y = -4 + (2/3)*x

Then the correct option is the third graph (rightmost graph).

Answer:

= [tex]\frac{34}{6561}[/tex]

Step-by-step explanation:

[tex]= 3^{-8}\times \:34\\= 34\times \frac{1}{3^{8} } \\= \frac{1\times \:34}{3^{8} } \\= \frac{34}{3^{8} } \\= \frac{34}{6561}[/tex]

Answer:

1/81

Step-by-step explanation:

Work Shown:

x^2 - 7x = -12

x^2 - 7x + 12 = 0

(x - 3)(x - 4) = 0 ... see note below

x - 3 = 0 or x - 4 = 0

x = 3 or x = 4

Note: we're looking for two numbers that multiply to 12 and add to -7. Those two numbers are -3 and -4, so that's where the factorization (x-3)(x-4) comes in. After this step, you set each factor equal to zero and solve for x.

Answer:

x=3  x=4

Step-by-step explanation:

x^2 − 7x = −12

Add 12 to each side

x^2 - 7x +12 =0

Factor

What 2 numbers multiply to 12 and add to -7

-3*-4 = 12

-3+-4 = -7

(x-3)(x-4) =0

Using the zero product property

x-3 =0   x-4 =0

x=3  x=4

Answer:

D.

Step-by-step explanation:

To find the equation of g(x), we can substitute the point into each of the equations.

A. g(x) = (1/4x)^2

1 = (1/4 * 2)^2

1 = (1/2)^2

1 = 1/4

This statement is false, so this is not the equation.

B. g(x) = 1/2 * x^2

1 = 1/2 * (2)^2

1 = 1/2 * 4

1 = 2

This statement is false, so this is not the equation.

C. g(x) = 2x^2

1 = 2 * 2^2

1 = 2 * 4

1 = 8

This statement is false, so this is not the equation.

D. g(x) = (1/2x)^2.

1 = (1/2 * 2)^2

1 = 1^2

1 = 1

This statement is true, so this is your answer.

Greetings from Brasil...

Here we don't have much to go

∛Y = A.(C + 1/X)

∛Y = (AC + A/X)

raising both members to the cube.....

(∛Y)³ = (AC + A/X)³

from Notable Products: (a + b)³ = a³ + 3a²b + 3ab² + b³

Y = (AC)³ + 3(AC)².(A/X) + 3AC(A/X)² + (A/X)³

Y = A³[C³ + (3C²/X) + (3C/X²) + (1/X³)]

Answer:

Variance population of 147,141,120,124,128 = 106

Variance sample of 147,141,120,124,128 = 132.5

Hope this helps and PLSSS MARK AS BRAINLIEST :)

Answer:

See below.

Step-by-step explanation:

The mean = (120+124+128+141+147) / 5

= 660 / 5

= 132

Difference between the values and the mean = -12, -8, -4, 9, 15.

Squares of these differences = 144, 64, 16, 81, 225

Sum of these squared differences =  530

So the variance = 530 / 5

= 106.

This is the population variance.

The sample variance = 530 / (5-1)

= 132.5.

Answer:

it is c because i took test review

Step-by-step explanation:

Answer:

C The solution should be 6, and the cyclists will need to ride 6 laps before the sprint to the finish.

The given point (2,5) is in the form (x,y). So x = 2 and y = 5.

Plug x = 2 into the equation given to find the predicted y value

y = 2.5x - 1.5

y = 2.5(2) - 1.5

y = 5 - 1.5

y = 3.5

We get a predicted y value of 3.5, and the actual y value is 5. Subtract the two values in this exact order

residual = (actual) - (predicted) = 5 - 3.5 = 1.5

A positive residual means that our predicted value is too small. A negative residual would be that the predicted value is too large.

Answer:

d=1.5

Step-by-step explanation:

y=2.5x-1.5   point (2,5)

f(2)=2.5(2)-1.5

f(2)=3.5           now we have two point , find the distance between them

(2,5) and (2,3.5)

d=√(x2-x1)²+(y2-y1)²

d=√(2-2)²+(3.5-5)²=

d=√1.5²=1.5

tried different way, it is 1.5

Answer:

Step-by-step explanation:

For the first triangle which is triangle <KJL

Hypotenuse= 8✓2

Angle=30°

Opposite = ?

Therefore we will use Sine formula

Sin30° = Y/8✓2

Y=4✓2

For the second triangle which is triangle <JML

Hypotenuse= 4✓2

Opposite=X

Angle=45°

Therefore we will use Sine formula again

Sin45°=X/4✓2

X=4

Answer:

Step-by-step explanation:

ΔJKL is half of equilateral triangle and ΔJML is half of square.

We can use properties of these triangles (picture):

m∠KJL=90° and m∠JKL = 30° ⇒  JL = 0.5KL = 0.5•8√2 = 4√2

m∠JML=90° and m∠MJL = 45° ⇒  JL = ML√2

                                                        4√2 = x√2

                                                             x = 4

Answer:

[tex]\frac{4}{3} \pi r^3[/tex].

Step-by-step explanation:

Let's say that the radius is r. The base diameter is two times the radius, or 2r.

Since the height is two times the diameter, the height is 2 * 2r = 4r.

The volume of a cone is 1/3 * h * pi * r^2. So, the volume of the cone is 1/3 * 4r * pi * r^2 = 1/3 * pi * 4r^3 = 4/3 * pi * r^3.

So, the volume of the cone is [tex]\frac{4}{3} \pi r^3[/tex].

Step-by-step explanation:

In order to get from point -1, 8, to point 2, -4, you would have to go down 12 and right 3, which would be 12/-3, which would simplify to -4

Answer:

Option B is the correct option

Step-by-step explanation:

Let the points be A and B

A ( -1 , 8 ) -----> ( x1 , y1 )

B ( 2 , -4 ) -----> ( x2 , y2 )

Now, let's find the slope of the line:

[tex] \frac{y2 - y1}{x2 - x1} [/tex]

plug the values

[tex] = \frac{ - 4 - 8}{2 - ( - 1)} [/tex]

Calculate the difference

[tex] \frac{ - 12}{2 - ( - 1)} [/tex]

When there is a (-) in front of an expression in parentheses , change the sign of each term in expression

[tex] \frac{ - 12}{2 + 1} [/tex]

Add the numbers

[tex] = \frac{ - 12}{3} [/tex]

Reduce the fraction with 3

[tex] = - 4[/tex]

------- = ----------

x+1         7

Using cross products

7x = 5(x+1)

Distribute

subtract 5x

7x-5x = 5x-5x+5

2x= 5

Divide by 2

2x/2 = 5/2

x = 2.5

Answer:

h = 6

Step-by-step explanation:

Step-by-step explanation:

Answer:b

Step-by-step explanation:

C and D are wrong because both of them should be divided and by 100. A is wrong because you are supposed to divide because if you multiply 3.5 x 100 its 350 and it just doesn’t make any sense because milli is smaller than deci. So by process of elimination b is the right answer.

Answer:

b

Step-by-step explanation:

:D

The spinner should land on yellow about 75 times, on red about 50 times, and on blue about 25 times.

Yellow: 3 spaces out of 6, so the probability is 3/6 = 1/2

Red: 2 spaces out of 6, so the probability is 2/6 = 1/3

Blue: 1 space out of 6, so the probability is 1/6

multiplying the probability of each color by 150:

Yellow: 1/2 * 150 = 75 times

Red: 1/3 * 150 = 50 times

Blue: 1/6 * 150 = 25 times

Terefore The spinner should land on yellow about 75 times, on red about 50 times, and on blue about 25 times.
