Answer:

x= 18°

Step-by-step explanation:

90° = 3x + 2x

90° - 5x

x = 90°/5

x = 18°

Answer:

answer is c

Step-by-step explanation:

Answer:

Simplifying

12x + 2y = 18

Solving

12x + 2y = 18

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2y' to each side of the equation.

12x + 2y + -2y = 18 + -2y

Combine like terms: 2y + -2y = 0

12x + 0 = 18 + -2y

12x = 18 + -2y

Divide each side by '12'.

x = 1.5 + -0.1666666667y

Simplifying

x = 1.5 + -0.1666666667y

Answer:

Hi

Step-by-step explanation:

First, you need to subtract both sides by 12x

12x+ 2y=18

-12x         -12x

That will give you: 2y= 18-12x

Next, you need to deviede both sides by 2

2y/2= 18-12x/2

That gives you the answer:

y= 18-6x

(im not 100%  sure but i think this is right, feel free to correct me)

Answer:

69.2km

Step-by-step explanation:

15km ÷ 13 mins = 1.153km (Average speed)

1 hour = 60mins

1.153km x 60 = 69.18km (Average speed in km/h)

69.18km = 69.2km (Rounded to 1 dp)

Answer: [tex]y = \frac{2}{3} x - 2[/tex]

Step-by-step explanation:

The slope intercept form is y = mx + b

Where m is our slope and b is our y-intercept

We're given a slope of 2/3

We're given a y-intercept of -2

Substituting into y = mx + b gives

[tex]y = \frac{2}{3} x - 2[/tex]

Answer:

y = (2/3)x - 2

Step-by-step explanation:

Use the slope-intercept form y = mx + b.  Here b = -2 and m = 2/3.  Making these replacements, we get:

y = (2/3)x - 2

Answer:

[tex](3+xz)(-3+xz)[/tex]

[tex](y^2-xy)(y^2+xy)[/tex]

Step-by-step explanation:

The Difference of Squares

Any difference of two squared monomial results in a factored form like shown below:

[tex]a^2-b^2=(a-b)(a+b)[/tex]

Similarly:

[tex](a-b)(a+b)=a^2-b^2[/tex]

For a product of binomials to be a difference of squares, they must be in the described form.

------------------------

(x-y)(y-x) can be rewritten as:

-(x-y)(x-y)

Since both binomials are identicals, the product will not result in a difference of squares.

-----------------------

(6-y)(6-Y)

Since both binomials are identicals, the product will not result in a difference of squares.

-----------------------

(3+xz)(-3+xz) can be rewritten as:

(xz+3)(xz-3). This product is a sum multiplied by a difference of the very same terms, thus the result is a difference of squares:

[tex](3+xz)(-3+xz)=(xz)^2-9[/tex]

-----------------------

[tex](y^2-xy)(y^2+xy)[/tex]. This product is a sum multiplied by a difference of the very same terms, thus the result is a difference of squares:

[tex](y^2-xy)(y^2+xy)=y^4-(xy)^2[/tex]

-----------------------

Summarizing:

(3+xz)(-3+xz)

[tex](y^2-xy)(y^2+xy)[/tex]

Answer:

undefined

Step-by-step explanation:

To find the slope of the line between two points, use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line passes through, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point the line also passes through. Therefore, use the x and y values of the points (0,3) and (0,4) to find the slope. Substitute them into the formula in the right order:

[tex]\frac{(4)-(3)}{(0)-(0)} \\= \frac{4-3}{0-0}\\=\frac{1}{0}[/tex]

However, we can't divide 1 by 0. Therefore, the slope is undefined. (You could also graph the points to see that they form a vertical line, and all vertical lines have an undefined slope.)

Answer:

A. $6.65

Step-by-step explanation:

To find how much 1/6 is you divide $7.98 by 6 and so the answer is $1.33. Now multiply $1.33 by 5 to get 5/6 or get the answer $6.65.

Answer: 18 quarts of sparkling water

Step-by-step explanation:

From the question, we are informed that a recipe for sparkling grape jucie calle for 1 1/2 quarts of sparkling water and 3/4 quart of grape jucie.

When there's an increase in the quarts of grape juice to 9, it simply means that the former grape juice has been multiplied 12 times (9 ÷ 3/4 = 9 × 4/3 = 12).

Therefore, we would also multiplybl the sparkling water given by 12 to get the new quantity needed. This will be:

= 1 1/2 × 12

= 3/2 × 12

= 18 quarts of sparkling water
