If x is direct proportional to y cube and x=32 when y=2
1. Find the value of x when y=6
2. Calculate the value of y when x=108

Answers

Answer 1

Answer:

1x=864,

2y=3

Step-by-step explanation:

y=6,x=?

if x is directly proportional to y^3 &if (when x=32, y is=2) we can understand that x=4y^3

1,x=4y^3

x=4(6^3)

x=4(216)

x=864

2,x=4y^3

108=4y^3

108/4=4y^3/4

27=y^3

√27=y

y=3

i think it is easy to understand,but if the answers are not clear you can ask me &i hope it helps you

Consider the statement "Two lines in a coordinate plane are parallel if and only if the slopes of the lines are m and m, where m is any real number." Is this statement true or false? Explain your reasoning.

Answers

Statement is true.

The slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts.

Answer:

Charles: 17 points

Adam: 25 points

Bethany: 30 points

Answer:

Adam scored 25 points.

Bethany scored 30 points.

Charles scored 17 points.

Step-by-step explanation:

A = Adam, B = Bethany, C = Charles

What we know:

C + 8 = A

A +  5 = B

A + B + C = 72

Charles:

C + 8 + 5 = B

C + (C + 8) +  (C + 13) = 72

72 - 8 - 13 = 51

51/3 = 17

Charles scored 17 points.

Bethany:

17 + 13 = 30

Bethany scored 30 points.

Adam:

17 + 8 = 25

Adam scored 25 points.

Answer:

Assuming you are asking for the slope which is 3 or in the equation format y=3x

Step-by-step explanation:

you must find the distance in the y- values and the x values, how each value increases or decreases. You may have heard of the phrase rise/run. To get to the pint (2,6) from (1,3), you must rise 3 units and move 1 unit. If you were to follow the rise/run method, you will need to divide the two numbers. In this case you will be dividing 3/1 which equals you. Then you must plug that number into the formula (y=mx+b).

Subtract sides minus r

[tex]r \times x \times y - r = - h[/tex]

The table below represents a function.

x y
0 1

5 26
7 50
Which equation makes the table true?

f( x) = 2 x + 1
f( x) = x 2 + 1
f( x) = x 2 - 1
f( x) = 2 x - 1

Answers

Answer:

f( x) = x ^2 + 1

The equation  f( x) = x² + 1 makes the table true.

What is equation?

Two or more expressions with an equal sign is called as equation.

The given  table is

x     y

0     1

2     5

5     26

7      50

The table value satisfy with the function f( x) = x² + 1=y

if x=0, then y=f(0)=0² + 1=1

if x=2, then y=f(2)=2² + 1=4+1=5

if x=5, then y=f(5)=5² + 1=25+1=26

if x=7, then y=f(7)=7² + 1=49+1=50

Therefore f(x)=x² + 1 is the equation of table.

The value of y varies directly with x. When y= 2 4/7, x= 37 .

What is the value of y when x is 27 ?


1 5/7

2 3/7

3 1/7

3 4/7

Answers

Answer:

Option (a).

Step-by-step explanation:

The value of y varies directly with x. It would mean that,

y=kx, where k is constant

When

[tex]y=2\dfrac{4}{7},x=\dfrac{3}{7}\\\\y=\dfrac{18}{7}, x = \dfrac{3}{7}[/tex]

then,

[tex]\dfrac{18}{7}=k\times \dfrac{3}{7}\\\\k=6[/tex]

When x = 27,

[tex]y=6\times \dfrac{2}{7}\\\\y=\dfrac{12}{7}\\\\\text{or}\\\\y=1\dfrac{5}{7}[/tex]

So, the value of y is [tex]1\dfrac{5}{7}[/tex] when x is 27.

0 C x= -10 and x= 3
O D. x= 10 and x= -3

Answers

Answer:

x^2+7x=30

x^2+7x-30=0

Here a=1,b=7 and c=-30

Now,

Discriminant(D)=b^2-4ac

=7^2-4×1×(-30)

=49+120=169

By applying Quadratic formula

x=-b+- root over b^2-4ac÷2a

=-7+- root over D ÷ 2×1

=-7 +- root over 169 ÷2

=-7 +- 13 ÷2

Now,

Either x=-7+13÷2=6÷2=3

Or x=-7 -13 ÷2=-20÷2=-10

Hence, ans is (C) x=-10 and x=3
