Answer:

y≤[tex]\frac{1}{3} x+1[/tex]

Step-by-step explanation:

Since the graph is facing down, We know the equation is y<mx+b

Since slope is rise/run the slope is 1/3.

Since the y intercept (The point where the line hits y) is 1, the equation is

y<1/3x+1

BUT WAIT!

The line is solid meaning that we have to include the line as part of the values. This will make the new equation

y≤[tex]\frac{1}{3} x+1[/tex]

Answer:

[tex]16a^2b^4[/tex]

Step-by-step explanation:

GCF= Greatest Common Factor

Given a polynomial, the GCF is the largest polynomial that will divide evenly into that polynomial.

The polynomial is

[tex]16a^4b^4 + 32a^3b^5 - 48a^2b^6[/tex]

First, we find the GCF of the coefficients:

16, 32, 48

Since 32 and 48 are multiples of 16, 16 is the GCF of the coefficients.

Now we select all the repeating variables with their smallest exponent:

[tex]a^4, a^3, a^2.\ GCF= a^2[/tex]

[tex]b^4, b^5, b^6.\ GCF=b^4[/tex]

The GCF of the polynomial is

[tex]\boxed{16a^2b^4}[/tex]

The corresponding sides have equal ratios, so the triangles are similar triangles.

From the question, we have:

In triangle ABC, AB = 3, BC = 5 and AC = 4

In triangle EDC, ED = 9, DC = 15 and EC = 12

For the triangles to be similar, then the corresponding sides must have an equivalent ratio.

This is calculated as:

[tex]\mathbf{Ratio = \frac{ED}{AB} = \frac{DC}{BC} = \frac{EC}{AC}}[/tex]

So, we have:

[tex]\mathbf{Ratio = \frac{9}{3} = \frac{15}{5} = \frac{12}{4}}[/tex]

[tex]\mathbf{Ratio =3 = 3 = 3}[/tex]

[tex]\mathbf{Ratio =3}[/tex]

Because the corresponding sides have equal ratios, then the triangles are similar.

Answer:

The tectonic plates.

Step-by-step explanation:

If you look at a diagram of Earth on Google, you'll see there's the crust, the mantle, the core...etc. If the tectonic plates are apart of the crust- which is the Earth's surface, then it's safe to assume the shell of the egg is the tectonic plates.

Answer:

C.) The amount of money she saved before attending lessons.

Answer:

(8 / x) + (21 / y)

Step-by-step explanation:

Given that:

Average driving speed = x mph

Miles driven to work = 8 mile

Miles by train to work = 21 miles

Average train speed = y

Total time taken to get to work. :

Recall : time taken = distance / speed

Hence,

Time taken =) total distance / average driving speed)

Total time taken = (8 / x) + (21 / y) hours

Total time taken = (8 / x) + (21 / y) hours

Answer: The average speed of the train is represented by x+20. When Megan drives at an average speed of 45 mph, it takes her approximately 0.50 hour to get to work.

Answer:

9/10

Step-by-step explanation:

Answer:

42.95 first price hiked 25%, then discounted by 25% : Final price = 40.28

42.95 first discounted by 25%, then price hiked by 25% : Final price = 40.27

Both are same (approx) because of same mathematical treatment

Step-by-step explanation:

Last season price = 42.95

This season increase in price = 25% of 42.95 = 10.73

Jeans price at beginning of this season = 53.68

Discount on sale price, this season = 25% of 53.68 = 13.42

Discounted jeans price this season = 53.68 - 13.42 = 40.28

Last season price = 42.95

Discount on previous price = 25% of 42.95 = 10.73

Jeans price this season = 42.95 - 10.73 = 32.22

Price hike this season = 25% of 32.22 = 8.05

New jeans price this season = 32.22 + 8.05 = 40.27

Step-by-step explanation:

Answer:On a coordinate plane, a straight line with a positive slope crosses the x-axis at (negative 1, 0) and crosses the y-axis at (0, 5)

Step-by-step explanation:

(f + g)(x) = -x² + 3x + 5 + x² + 2x = 5x + 5

=> y = 5x + 5

=> the slope is positive

the line crosses the x-axis at (-1;0) and the y-axis at (0;5)

Answer:

Step-by-step explanation:

Answer:

(a) x = 2

Step-by-step explanation:

x - 12 = -8x + 6

First, move all the like terms to one side of the equation. We will move all the x's to the left, and the rest to the right in this equation. (Don't forget to pay attention to the signs of the numbers as you move them over the equal sign.)

x - 12 + 8x = 6

x + 8x = 6 + 12

9x = 18

Next, solve for x by isolating it to one side of the equation. Here, we'll have to divide 18 by 9 (do the opposite of what 9 is doing with x; instead of multiplying it with 18 like it currently is with x, divide 18 by it.)

x = [tex]\frac{18}{9}[/tex]

x = 2

Therefore, your answer is (a), since x = 2.

Answer: 11/15

Hope this helps! ^^

Answer: The answer in improper form is 11/15 or in mixed number form it is 12 1/5... I did this by dividing the Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

2/3 * 11/10

For fraction multiplication, multiply the numerators and then multiply the denominators to get

2*11/3*10=  22/30

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 22 and 30 using 22 divided by 2/30 divided by 2 which equals 11/15.

Therefore 2/3 divided by 10/11 equals 11/15
