Answer:

[tex]14a^{2}b[/tex] + [tex]28ab^{2}[/tex] - 42ab

Step-by-step explanation:

The expression 7ab(2a+4b-6) simplifies as 14a^2b + 28ab^2 - 42ab by distributing 7ab to each number within the parentheses.

This question involves distribution which is a property in Mathematics. To simplify the expression

7ab(2a+4b-6), you need to distribute or multiply 7ab with each number within the parentheses. When we do this step-by-step:

So, the expression 7ab(2a+4b-6) simplifies as 14a2b + 28ab2 - 42ab.

To confirm if triangle MNP is a dilation of triangle JKL, one must examine the ratios of the corresponding sides. In a dilation, a figure's size changes but its shape and the angles between its sides remain the same, and the lengths of the sides remain proportional. Without the specific measurements, it's not possible to definitively say if MNP is indeed a dilation of JKL.

To determine if triangle MNP is a dilation of triangle JKL, we need to examine the ratios of the corresponding sides. Dilation in mathematics is a transformation that alters the size of a figure without changing its shape or the angles between its sides. In a dilation, the lengths of the sides are proportional.

For example, if triangle MNP has sides that are twice as long as the corresponding sides of triangle JKL, then MNP is a dilation of JKL by a factor of 2.

If the sides of triangle MNP do not maintain the same proportionality with triangle JKL, then triangle MNP is not a dilation of triangle JKL. Therefore, without concrete values or further details, it's difficult to definitively answer whether MNP is a dilation of JKL.

Answer:

The cost of one bag of diapers is $11 and the cost of one can of formula is $13

Step-by-step explanation:

Let

x -----> the cost of one bag of diapers

y ----> the cost of one can of formula

we know that

[tex]x+2y=37[/tex] -----> equation A

[tex]2x+5y=87[/tex] ----> equation B

Solve the system by graphing

Remember that the solution of the system is the intersection point both graphs

The solution is the point (11,13)

see the attached figure

therefore

The cost of one bag of diapers is $11 and the cost of one can of formula is $13

Final answer:

The cost of one bag of diapers is $11, and the cost of one can of formula is $13, as determined by solving a system of two linear equations that describe Malik's purchases.

Explanation:

The student is presented with a system of linear equations based on the purchases made by Malik at different times. The purchases involve a bag of diapers and cans of formula, with the total amounts spent being provided. This information can be turned into a system of equations to solve for the price of one bag of diapers and the price of one can of formula.

Let D represent the cost of one bag of diapers and F represent the cost of one can of formula. From the given information, we can construct the following equations:

D + 2F = $37 (Equation 1: One bag of diapers and two cans of formula cost $37)

2D + 5F = $87 (Equation 2: Two bags of diapers and five cans of formula cost $87)

Now, let's solve this system of equations using the method of substitution or elimination. For simplicity, let's use the elimination method:

Multiply Equation 1 by 2, so it can be arranged to eliminate D:
2D + 4F = $74

Subtract Equation 1 modified from Equation 2:
(2D + 5F) - (2D + 4F) = $87 - $74,
which simplifies to F = $13.

Now plug the value of F back into Equation 1:
D + 2($13) = $37,
D + $26 = $37,
therefore D = $37 - $26,
D = $11.

Therefore, the cost of a bag of diapers is $11, and the cost of one can of formula is $13.

Answer:

x = 9

Step-by-step explanation:

The trick here is knowing that JKM and MKL are equal, which means MKL is equal to JKL/2. From that knowledge, we can solve.

MKL = JKL/2

5x + 1 = 46

5x = 45

x = 9

The value of the x is 9 if KM bisects JKL, m JKL = 92, and MKL = (5x+1).

Since KM bisects JKL, it divides the angle JKL into two congruent angles. Therefore, angle MKL is equal to angle JKL divided by 2.

Given that angle JKL is 92 degrees, we can find the value of x by setting up the following equation:

5x + 1 = 92/2

First, we simplify the right side of the equation:

92/2 = 46

Now, we can solve for x:

5x + 1 = 46

5x = 46 - 1

5x = 45

x = 45/5

x = 9

Therefore, the value of x is 9.

Answer:

Given the domain D = {-1, 0, 3}, the range of f(x) = 3x - 5, is {-8, -5, 4}.

Step-by-step explanation:

To find the range you have to replace the values indicated by the domain in the function (range refers to "y" values of the function).

f(-1) = -8

f(0) = -5

f(3) = 4.

So the range for the given domain is  {-8, -5, 4}.

Answer:  The required range of the given function is {-8, -5, 4}.

Step-by-step explanation:  We are given to find the range of the following function :

[tex]f(x)=3x-5,~~D=\{-1,0,3\}.[/tex]

Since the domain D contains points -1, 0 and 3, so the range will be the following set :

{f(-1), f(0), f(3)}.

We have

[tex]f(-1)=3(-1)-5=-3-5=-8,\\\\f(0)=3\times0-5=-5,\\\\f(3)=3\times3-5=4.[/tex]

Thus, the required range of the given function is {-8, -5, 4}.

Answer:

This answer is 8

Step-by-step explanation:

It actually is very simple. For this question you do not even need the g(x) equation to continue, so put it aside for now. F(x) means that whatever number that will take the place of x will be used in this equation. If f(x)=3x-1, then f(3)=3(3)-1

This happens because the 3 in f(3 tells you to substitute x for 3 in the equation. ) So just plug in 3 for x and solve to get the answer 8.

Step-by-step explanation:

First, find the rate of change [slope]:

-y₁ + y₂\-x₁ + x₂ = m

[tex] \frac{7 + 9}{4 - 6} = -\frac{16}{2} = -8[/tex]

Then use the Point-Slope Formula since we are given points. Now, according to this formula, all negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY careful inserting the coordinates into the formula with their CORRECT signs. It does not matter which one you choose:

y - y₁ = m(x - x₁)

y - 9 = -8(x + 6)

y - 9 = -8x - 48

Answer: FIRST OPTION.

Step-by-step explanation:

By definition, the "Angle formed by a Tangent and a Secant" is:

[tex]Angle\ formed\ by\ Tangent\ and\ Secant=\frac{1}{2}({Difference\ of\ Intercepted\ Arcs)[/tex]

In this case you can identify in the figure that the Intercepted Arcs are:

 [tex]LP=x[/tex] and [tex]PM=y[/tex]

And the Angle formed by the tangent and the secant is:

[tex]\angle MNP[/tex]

Therefore, the following equation can be used to calculate the measure of the angle ∠MNP:

[tex]m\angle MNP=\frac{1}{2}(LP-PM)\\\\m\angle MNP=\frac{1}{2}(x-y)[/tex]

This matches with the First option.
