Answer:

Step-by-step explanation:

Answer:

Juan = 93 years.

Gabe = 31 years.

Catherine = 25 years.

Step-by-step explanation:

Let the age of Juan = J

Let the age of Gabe = G

Let the age of Catherine = C

Translating the word problem into an algebraic equation, we have;

[tex] J = 3G[/tex] ..........equation 1

[tex] G = C + 6 [/tex] ........equation 2

[tex] J + G + C = 149 [/tex] ........equation 3

We would solve the linear equations by using the substitution method;

Substituting equation 2 into equation 1;

[tex] J = 3(C + 6)[/tex]

[tex] J = 3C + 18[/tex] ........equation 4

Substituting equation 2 and equation 4 into equation 3;

[tex] (3C + 18) + (C + 6) + C = 149 [/tex]

Simplifying the equation, we have;

[tex] 5C + 24 = 149[/tex]

[tex] 5C = 149 - 24[/tex]

[tex] 5C = 125[/tex]

[tex] C = \frac {125}{5}[/tex]

C = 25 years.

To find G; from equation 2

[tex] G = C + 6[/tex]

Substituting the value of "C" into equation 2, we have;

[tex] G = 25 + 6[/tex]

G = 31 years.

To find J; from equation 1

[tex] J = 3G [/tex]

Substituting the value of "G" into equation 1, we have;

[tex] J = 3 * 31[/tex]

J = 93 years.

Therefore, Juan is 93 years old, Gabe is 31 years old and Catherine is 25 years old.

Answer:

b; vertically compressed by a factor of 2

Step-by-step explanation:

Here, we want to select from the options, the transformation that was not done on the parent function;

a) shifted up seven units

This was done

as we can see, we have + 7 from the initial 0 point

b) vertically compressed by a factor of 2

This is wrong

What we had is 1/2 multiplied by x

If there is any compressor done, it is to a factor of 1/2 and not 2

This, is thus our answer

Answer:x<2

Step-by-step explanation:

Answer:

(23, 9,200) (26, 10,400)

those are the only 2

Given :

An expression (cos 6m)(cos 2m) .

To Find :

We need to express it in terms as sum or difference.

Solution :

We know,

cos( A + B ) = cosA cos B - sin A sin B

cos( A - B ) = cosA cos B + sin A sin B

Adding both the equations we get :

2cos A cos B = cos( A + B) + cos( A - B )

or

cos A cos B = cos( A + B) + cos( A - B )/2

Putting value of A = 6m and B = 2m in above equation, we get :

(cos 6m)(cos 2m) = cos( 6m + 2m ) + cos( 6m - 2m )/2

(cos 6m)(cos 2m) = cos(8m) + cos(4m)/2

Hence, this is the required solution.

Answer:

1 1/3 feet long

Step-by-step explanation:

Answer:

Each of the seven smaller boards will be 1.3 feet long

Step-by-step explanation:

We must divide 9 1/3 by 7

9 1/3 / 7 =  1.333286

We now have to round to the nearest tenth which would give us:

1.3

So our final answer would be 1.3

Answer:

13.5

Step-by-step explanation:

the answer is 13.5, because you do the proportionate equations of 6/4 = x/9, and then you cross multiply to get 4x=54, and then you isolate x, so the answer is 13.5

Answer:

Slope = -1/2

Step-by-step explanation:

Use y = mx + b to find the slope (m) Write the expression as an equation (-14y)-7x=0. Rewrite in slope-intercept form by removing the parentheses, adding 7x to both sides, dividing each term by -14, then writing in y = mx + b form, which is m=-1/2x. Remove the variable, it becomes your answer of -1/2.

Answer:

x = [tex]\frac{2}{5}[/tex] , x = ± i

Step-by-step explanation:

Given

5x³ - 2x² + 5x - 2 = 0 ( factor the first/second and third/fourth terms )

x²(5x - 2) + 1(5x - 2) = 0 ← factor out (x - 2) from each term

(5x - 2)(x² + 1) = 0

Equate each factor to zero and solve for x

5x - 2 = 0 ⇒ 5x = 2 ⇒ x = [tex]\frac{2}{5}[/tex]

x² + 1 = 0 ⇒ x² = - 1 ⇒ x = ± [tex]\sqrt{-1}[/tex] = ± i

The polynomial is of degree 3 and has 3 roots, 1 real and 2 complex, that is

x = [tex]\frac{2}{5}[/tex] ← real root

x = ± i ← complex roots

Answer:

1) [tex]16\frac{2}{3}[/tex]% or 20%

Step-by-step explanation:

Given that:

An experiment which is carried out by flipping a coin and rolling six sided die.

The outcomes can be:

{H1, H2, H3, H5, H6, T1, T1, T2, T3, T5}

As per question statement:

Number of outcomes having tails and an odd number greater than one is 2 (i.e. T3 and T5)

Total number of outcomes here is 10.

Therefore, to find the percentage, we use the following formula:

[tex]\dfrac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\times 100[/tex]

[tex]\Rightarrow \dfrac{2}{10}\times 100 = 20\%[/tex]

As per question statement, the answer is 20%.

If we consider all the outcomes, i.e.

{H1, H2, H3, H4, H5, H6, T1, T2, T3, T4, T5, T6}

Total number of outcomes = 12

The percentage will come out be :

[tex]\Rightarrow \dfrac{2}{12}\times 100 = 16\frac{2}{3}\%[/tex]

Step-by-step explanation:

Answer:

B and E

Step-by-step explanation:

B because they are both congruent the only difference is that shape 4 is in a angle and E the only difference is that 2 is bigger but they are still congruent.

Answer:

False

Step-by-step explanation:

Assuming that the first equation is 10x - 12, you need to solve both equations in order to see if the equations are equivalent from each other.

[tex]10x-12[/tex]

[tex]10x-12=2(5x-6)[/tex]

[tex]=2(5x-6)[/tex]

Then...

[tex]2\times(52-6)[/tex]

Use Order of Operations...

[tex]52-6=46[/tex]

[tex]2\times46=92[/tex]

[tex]2(5x-6)<96[/tex]

Therefore "false" or the second option is your answer.

Hope this helps.

Answer:

The lines that could be the image of line m after a dilation are;

C. n

E. p

Step-by-step explanation:

A dilation is the operation performed on a geometric figure, that involves the uniform enlargement or uniform shrinking of the figure from a given center of dilation, such that the shape of the figure, which can be a line segment, a polygon, or a point on the coordinate plane

From the given options, the lines l and consists of rotation of the line m and are therefore not purely dilations of the line m

Dilation Is the process of increasing or decreasing a figure by a scale factor..The line n and p is the image of the line m after the dilation.

There are total 5 lines are given in the image shown.

Dilation Is the process of increasing or decreasing a figure by a scale factor. When the lines are shorter or longer with the ratio of the original line then it is called the dilation of the line.

The center point of the dilation must be same for the original line and the dilated line.

For the given figure there are total  5 lines are given. Lets check all one by one,

Thus the line n and p is the image of the line m after the dilation.
