What expressions are equivalent to 12+84

Answer:

y = - 4.98

Step-by-step explanation: This statement means

y

∝

x

, which can also be written in the form

y

=

k

x

when it is directly proportionate and

y

=

k

x

when inversely proportionate, where

k

is a value we need to work out. Since the equation is in the form

y

=

Answer:

  D.  J(x) = 1/4(-x)^3

Step-by-step explanation:

Reflection across the y-axis replaces x with -x. Then if Fr(x) represents the reflected function, we have ...

  Fr(x) = (-x)^3.

Compression by a factor of c < 1 multiplies the function value by c. Then ...

  J(x) = 1/4·Fr(x)

  J(x) = (1/4)(-x)^3

Answer:

49 degrees

Step-by-step explanation:

The angles of a triangle must add up to 180 degrees. So, f = 180 - 82 - 49 = 49.

Hello BATAPAAKO!

[tex] \huge \boxed{\mathbb{QUESTION} \downarrow}[/tex]

Solve the inequality: x+10>2x/5.

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

[tex]x + 10 \gt \frac { 2 x } { 5 } \\ [/tex]

Firstly, multiply both sides of the equation by 5.

[tex]5(x + 10) > 2x \\ = 5x + 50 > 2x[/tex]

Since 5 is greater than 0, the direction of the inequality will remain unchanged. Now, subtract 2x from both the sides.

[tex]5x + 50 > 20 \\ = 5x + 50 - 2x > 0[/tex]

Combine 5x & -2x to get 3x.

[tex]5x + 50 - 2x > 0 \\ = 5x - 2x + 50 > 0 \\ = 3x + 50 > 0[/tex]

Now, subtract 50 from both the sides. Remember :- anything subtracted by 0 will result in its negation. So 50 subtracted from 0 will give you -50.

[tex]3x + 50 > 0 \\ = 3x > - 50[/tex]

Divide both sides of the equation by 3. Again, since 3 is > 0, the direction of inequality will remain unchanged.

[tex]3x > - 50 \\ = \large\boxed{\boxed{ \bf \: x > - \frac{ 50}{3} }}[/tex]

Answer:

y = -[tex]\frac{1}{3}[/tex] + 4

Step-by-step explanation:

first of all we know the slope of the equation which is 3x. then we know that we are supposed to write an equation that is perpendicular to y = 3x + 3. so since it is supposed to be perpendicular we have to make the current slope opposite.

so slope for our new equation will be -[tex]\frac{1}{3}[/tex]x.

now since we know our slope we use point-slope form and plug everything in.

point-slope form: y1-y=m(x1-x)

plug it in:

y - 2 = -[tex]\frac{1}{3}[/tex] (x - 6)

= y - 2 = -[tex]\frac{1}{3}[/tex]x +2

= y = -[tex]\frac{1}{3}[/tex] + 4

Answer:

x^2+y^2=256

Step-by-step explanation:

The general formula for a circle is (x - h)^2 + (y - k)^2 = r^2; where (h , k).

Thus, (x - 0)^2 + (y - 0)^2 = (16)^2 is x^2 + y^2 = 256

The type of transformation must the line segment have undergone if Sandra transforms a line segment such that the new image is longer than the original line segment, is dilation, so option A is correct.

The process of dilation entails scaling or changing a thing. It is a transformation that uses the specified scale factor to make the objects smaller or larger.

Given:

Sandra transforms a line segment such that the new image is longer than the original line segment,

The above transformation is an example of dilation, as in dilation the image can be transformed into a large image or a small image,

Thus, the given transformation is an example of dilation.

We have that, how long it will take for Liu to catch Mariel is mathematically given as

t=3.076s

From the question we are told

Mariel and Liu are running a long-distance race. Mariel runs at a rate of 5.4 m/s, and Liu runs at a rate of 7.6 m/s. If Mariel has a 20 m head start, how long will it take for Liu to catch Mariel?

Generally the equation for the Average speed is  mathematically given as

[tex]v_a=\frac{5.4+7.6}{2}\\\\V_a=6.5m/s[/tex]

The subsets of {10, 19, 5, 0} are

{ } - the empty set, or 1 subset of size 0

{10}, {19}, {5}, {0} - 4 subsets of size 1

{10, 19}, {10, 5}, {10, 0}, {19, 5}, {19, 0}, {5, 0} - 6 subsets of size 2

{10, 19, 5}, {10, 19, 0}, {10, 5, 0}, {19, 5, 0} - 4 subsets of size 3

{10, 19, 5, 0} - 1 subset of size 4

A proper subset of a set is any subset of that set that is not equal to that set. The only subset that is not a proper subset is {10, 19, 5, 0}, since that's the set itself. So there are 15 proper subsets.

In general, a set of size n has a total of 2ⁿ subsets, and 2ⁿ - 1 proper subsets.
