Jorge says the first step to solving the equation below is to combine like terms on each side of the equal sign. David says you should distribute first then isolate x. Which perspective do you agree with and why? Determine the solution to the equation.
x + 2x + 3 + 3 = 3(x + 2)

Answer:

11a.  (1, 1)

11b.  (2, 2)

Step-by-step explanation:

A function cannot have an x-value that produces multiple different y-values.  A function can have a y-value that produces multiple different x-values.

For this question, you could put in a number of different points and still get the right answer.  If you work through this problem yourself again and pick different points from mine, it doesn't mean that it is wrong.  As long as it follows the rules stated above, you will get the correct answer.

11a.  (1, 1)  

This is an x-value that was not stated in the data set.  This means that, as far as we know, there is only one y-value for the x-value of 1.

11b.  (2, 2)

This is an x-value that was stated in the data set.  This means that for the x-value of 2, there are two y-values: 2 and 8.

c) j = 95 degree (similar triangle)

d) jk/4 = 4.6/9.2

jk/4 = 1/2

jk = ?

Answer:

angle k = 30.4

Step-by-step explanation:

Large triangle :

95 + 15 = 110

180 - 110 = 70 degrees

Now, the second triangle is 2.3 times larger than the first one.

(9.2 divide 4 = 2.3)

so, 70 degrees divided by 2.3 = 30.4

Answer:

S = π( 2(9) + 2(3)(14))

Step-by-step explanation:

Here we are to select which of the options best describe the equation that could be used to find the surface area of the cylinder.

Mathematically,

the surface area of a cylinder can be calculated using the formula

S = 2 π r^2 + 2 π rh

from the question, we have r as d/2 = 6/2 = 3cm and h = 14cm

We plug these two values into the equation above

Thus, we have

S = 2 * π * 3^2 + 2 * π * 3 * 14

S = π( 2(9) + 2(3)(14))

Answer:

r = [tex]\sqrt{11}[/tex]

Step-by-step explanation:

So we need to complete the square for both parts of the equation

First though we can add the 6 to the other side so we have x² + 2x + y² + 4y = 6

So first we can complete the square for x² + 2x

To do so we need to use [tex](\frac{b}{2} )^{2}[/tex] to figure out the number we need to add to both sides

In this case our b is 2, so substituting this in we get [tex](\frac{2}{2} )^{2} =(1)^{2} =1[/tex]

Here we add 1 to both sides and now we have x² + 2x + 1 + y² + 4y = 6 + 1

Now we can follow the same steps to complete the square for y² + 4y

Here our b is 4, so substituting this in we get [tex](\frac{4}{2} )^{2}=(2)^{2} =4[/tex]

Now we add 4 to both sides and now we have x² + 2x + 1 + y² + 4y + 4 = 6 + 1 + 4

Now condensing everything we have (x + 1)² + (y + 2)² = 11

The formula for a circle is (x - h)² + (y - k)² = r²

In our equation we have r² = 11

To find the radius we need to take the square root of both sides [tex]\sqrt{r^{2}} =\sqrt{11}[/tex] to get r = [tex]\sqrt{11}[/tex]

Answer:

See Below:

Step-by-step explanation:

b*3/5 = l

where b is the cost of the bill, being multiplied by 3/5 to find out how much of it was l, labor cost.

We now labor was 79.50 so we substitute that for l.

b*3/5= 79.50          We now multiply by 5/3 on both sides to isolate b, the cost of the bill.

b=  132.50

The correct equation is D, 3/5*b = 79.50 and the total bill was 132.50

80

Step-by-step explanation:

Geoff's number is 80. We can figure this out by reversing the steps.

Instead of dividing, we can multiply 3 by 25 to get the number in which 5 was subtracted to get that number.

3 x 25 = 75

75 + 5 = 80

Therefore, Geoff's number is 80.

A, B and C

Step-by-step explanation:

Given any three side lengths of a right triangle, the longest side is the hypotenuse.

The side lengths  of a right triangle must satisfy the Pythagorean Theorem.

Pythagorean Theorem: [tex]Hypotenuse^2=Opposite^2+Adjacent^2[/tex]

Option A: [tex]3, 6, \sqrt{45}[/tex]

[tex](\sqrt{45})^2=3^2+6^2\\45=36+9\\45=45[/tex]

True

Option B: 2.5, 6, 6.5

[tex]6.5^2=6^2+2.5^2\\42.25=36+6.25\\42.25=42.25 (TRUE)[/tex]

Option C: [tex]4, 8, \sqrt{80}[/tex]

[tex]4, 8, \sqrt{80}\\( \sqrt{80})^2=4^2+8^2\\80=16+64\\80=80 (TRUE)[/tex]

Since all are true, the side lengths in Options A, B and C forms a right triangle,

GF = GE so GE = 7x-3

Answer:

GE = 38

Step-by-step explanation:

6x + 2 = 7x - 3

6x + 5 = 7x

5 = x

Put the variable into the equation of GF, since GF and GE make a square therefore are equal.

7(5) - 3

GE = 38

Answer:

Step-by-step explanation:

The scale factor is 2/3

2/3=2*2/2*3=4/6

2/3=2*3/3*3=6/9

The two figures are similar and the scale factor of the first figure to the second figure is [tex]\frac{2}{3}[/tex]

The scale factor is a measure for similar figures, who look the same but have different scales or measures.

From the given figure take the same sides of both figure

Width = [tex]\frac{6}{9}=\frac{2}{3}[/tex]

Length = [tex]\frac{4}{6}=\frac{2}{3}[/tex]

Height = [tex]\frac{2}{3}[/tex]

Therefore the scale factor is [tex]\frac{2}{3}[/tex]

Hence, the two figures are similar and the scale factor of the first figure to the second figure is [tex]\frac{2}{3}[/tex]

Answer:

A

Step-by-step explanation:

While the obvious answer might be Book B because that had the most amount of teachers that approved it, I looked at it a different way. I think that the best book has the greatest percentage of teachers approved compared to the total teachers who reviewed the book. Let's apply this to the 4 books.

A: Approved = 8 Total = 9    8/9 = 88%

B: Approved = 24 Total = 29    24/29 = 83%

C: Approved = 12 Total = 16    12/16 = 75%

D: Approved = 20 Total = 26   20/26 = 77%

As you can see, Book A should be chosen because it has the highest percentage. I hope this helps and makes sense!
