Answer:

Step-by-step explanation:

2k+1 = 3k -2

k =3

every child has a 1 mom

f 7 = 3 f7= -6 this is imposible

[tex]\sf \boxed{\bold{k = 3}}[/tex]

Explanation:

If the first values of the two ordered pairs are the same, the relation is not a function.

Solve:

2k + 1 = 3k -2

2k - 3k = -2-1

-k = -3

k = 3

When k = 3, for the relation R= {(2k+1, 3), (3k-2, -6)} will not be a function.

The equivalent expression of the expression [tex]\sqrt[3]{\frac{12x^2}{16y}}[/tex] is [tex](\frac{3x^2}{4y})^\frac 13[/tex]

The expression is given as:

[tex]\sqrt[3]{\frac{12x^2}{16y}}[/tex]

Divide 12 in the expression by 4

[tex]\sqrt[3]{\frac{3x^2}{16y}}[/tex]

Divide 16 in the expression by 4

[tex]\sqrt[3]{\frac{3x^2}{4y}}[/tex]

Apply the power rule of indices

[tex](\frac{3x^2}{4y})^\frac 13[/tex]

Hence, the equivalent expression of [tex]\sqrt[3]{\frac{12x^2}{16y}}[/tex] is [tex](\frac{3x^2}{4y})^\frac 13[/tex]

Step-by-step explanation:

I may be wrong but heres how I solved it.

12 minutes out of 480 minutes is 2.5%

The probability that the spinner will land on a number greater than 4 or on a shaded section is five-sixt

Probability is the likelihood or chance that an event will occur. Mathematically;

Probability = Expected/Total

If the spinner is spinned, the total outcome is 1/6

Pr(greater than 4) = 2/6 = 1/3

Pr(shaded section) = 3/6 = 1/2

Pr(number greater than 4 or on a shaded section) = 1/3 + 1/2
Pr(number greater than 4 or on a shaded section)  = 5/6

Hence the probability that the spinner will land on a number greater than 4 or on a shaded section is five-sixths

Answer:

8/15 is the fraction I think

The answer is that 50% of the sweaters cost $50 or less.

To determine the fraction of sweaters that cost $50 or less, we need to look at the box plot and identify the range of prices that fall within that category.

Looking at the box plot, we can see that the box extends from $40 to $60, which means that 50% of the sweaters sold were priced between $40 and $60. Additionally, we can see that the left whisker of the box plot extends down to $30, which means that some sweaters were sold for less than $40.

Therefore, to find the fraction of sweaters that cost $50 or less, we need to calculate the portion of the box plot that falls below $50.

From the box plot, we can see that the distance between $40 and $50 is half of the total distance of the box or 25%. And the distance between $30 and $40 is also 25%. Therefore, the total fraction of sweaters that cost $50 or less is 25% + 25% = 50%.

So, the answer is that 50% of the sweaters cost $50 or less.

Just did the assignment

a $2.00

Step-by-step explanation:

0.50 x 4 = 2

If he bought 4 times as many, then take the price times 4.

Answer:

$2.00

Step-by-step explanation:

Stephen bought 1 package for $0.50. His brother bought 4 times as many (4 * 1 packages). Which means his brother bought 4 packages.

If each package costs $0.50 then we simply multiply the price with the amount of packages he bought:

4 * $0.50. Lets get rid of the dollar sign, so it doesn't distract us.

I'm not sure if you studied about floating point numbers yet, but I assume you did.

4 * 0.50 =?

We have two numbers after the floating point, but for the sake of simplicity we can get rid of it too and just multiply 4 * 50 and then put the floating point back into the number after the first two digits (because we removed it after two digits 0.50)

Anyway 4 * 50 = 200

We add the floating point and get:

2.00

Therefore his brother spent $2.00 after we add the dollar sign back in

The question is an illustration of transformation, and the coordinates of the image of the triangle are (-3,7), (-2,4) and (0,6)

The coordinates of the triangle are given as:

(-6,-1), (-5,2) and (-3,0)

When the triangle is reflected across the line y = 2 is, the new points are

(-6,5), (-5,2) and (-3,4)

Next, we translate the image of the triangle using the translation

(x,y) -> (x + 3, y +2)

So, we have:

(-6,5) => (-6 + 3, 5 + 2) = (-3,7)

(-5,2) => (-5 + 3, 2 + 2) = (-2,4)

(-3,4) => (-3 + 3, 4 + 2) = (0,6)

Hence, the coordinates of the image of the triangle are (-3,7), (-2,4) and (0,6)

Answer:

x=0 , x=-3

Step-by-step explanation:

Apply all exponent rules:

[tex]3^{x+3}[/tex] = [tex]3^{x}[/tex]×[tex]3^{3}[/tex]

[tex]\frac{1}{3^{x} }[/tex] = [tex](3^{x} )^{-1}[/tex]

Rewrite equation with [tex]3^{x}= u[/tex]

[tex]u[/tex] × [tex]3^{3}[/tex] + [tex]u^{-1}[/tex] - 28 = 0

Solve for u to give :

u = 1, u = 1/27

Substitute back u = [tex]3^{x}[/tex], solve for x :

[tex]3^{x}[/tex] = 1 , x= 0

[tex]3^{x}= \frac{1}{27}[/tex] , x= -3  
x=0 , x=-3

Substituting x back into original equation verifies our answers
