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:

x=71/9, y= -47/9

Step-by-step explanation:

5x+2y=29

x+4y=13 subtract 4y from both sides

x= -4y+13 substitute on the first one

5( -4y+13) + 2y = 29 distribute in parenthesis

-20y - 65 +2y =29 add 65 to both sides

-20y +2y = 29+65 combine like terms

-18y = 94 divide by -18 both sides

y= 94/-18= -47/9

substitute y =-47/9 in x=-4y+13

x=-4(-47/9)+13=(188/9)+13=188+117/9=71/9

Answer:

9/10

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.

I hope this helps! I would really appreciate it if you would please mark me brainliest! Have a blessed day!

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:

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

3. Distributive

Step-by-step explanation:

In the equation 3(x - 2y) if you distribute the 3 to the x and the -2 you would get 3x-6y.

The property illustrated in the equation is 3)Distributive

Distributive law, also called distributive property, in mathematics, the law relating the operations of multiplication and addition, stated symbolically as a(b + c) = ab + ac; that is, the monomial factor a is distributed, or separately applied, to each term of the binomial factor b + c, resulting in the product ab + ac.

Given here, 3x-6y=3(x-2y)

Thus clearly 3 is distributed over x and 2y

Hence, The property illustrated in the equation is 3)Distributive

Answer: 40

Step-by-step explanation:

using dimensional analysis ( you might not have learned this yet, but it's basically multiplying things to cancel out units)...

200 ml * (1 tsp/ 5 ml) = 40 tsp  

200 milliliters is equal to 40 teaspoons.

Here, we have,

given that,

1 tsp = 5 ml

so, we get,

If 1 teaspoon (tsp) is equal to 5 milliliters (ml),

then to find how many teaspoons are in 200 milliliters (mL),

we have to divide 200 by 5:

so, we get,

200 mL / 5 mL/tsp

= 40 teaspoons (tsp)

i.e. 200 ml * (1 tsp/ 5 ml) = 40 tsp  

So, 200 milliliters is equal to 40 teaspoons.

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]
