help!! i don’t understand geometry

Answer:

(0, 12 )

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (- 5, - 3)

m = [tex]\frac{-3-3}{-5+3}[/tex] = [tex]\frac{-6}{-2}[/tex] = 3 , then

y = 3x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 3, 3 ), then

3 = - 9 + c ⇒ c = 3 + 9 = 12 ← y- intercept

Thus the line crosses the y- axis at (0, 12 )

Answer:

It crosses the y-axis at the point where y = 12

- the point (0, 12).

Step-by-step explanation:

First we need to find the equation of the line q:

The slope of the line = (-3-3)/(-5-(-3))

= -6/-2

= 3.

Using the point-slope form of a line:

y - y1 = m(x - x1)         Take the point (-3, 3):

y - 3 = 3(x -(-3)

y - 3 = 3x + 9

y = 3x + 12.

Where q crosses the y-axis x = 0 so we have

y = 3(0) + 12

y = 12

The required point is (0, 12).

Answer:

3 1/3 Because When we divide two fractions, such as 5/2 ÷ 3/4, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.

Step-by-step explanation:

remember to simplify if ever possible!:D

soooo

in order to do this both fractions has to have the same denominator

so you find the CMD (common denominator)

which is 4

so you'd only change 5/2

5/2 * 2/2 to make it 10/4

now both fractions have the same denominator

you do keep change flip

you keep 10/4

change division to multiplication

and flip 3/4 TO 4/3

which would equal

10/4 * 4/3= 40/12

40/12

and you divide it with long division

you get 3 as ur quotient

divisor as 12

and remainder as 4

= 3 4/12

nd u simplify which u divide 4/12 by 4 and get 1/3

so the answer would be 3 1/3

and in order to check you can use an online fraction calculator

Answer:

(x-2)(x-11)

Step-by-step explanation:

Answer:

(x - 2)(x - 11)

Step-by-step explanation:

We have a polynomial and are asked to factor it.

Polynomial : x^2 - 13x + 22

Usually a trick I follow when factoring is that for c (in this case 22). You need to find two numbers that will multiply to it. And for b (in this case -13) you will need to find two numbers that will add to it, the same numbers you multipled for c.

So

x * y = 22

x + y = -13

These two numbers are -11 and -2.

Answer:

The second option, B.

[tex](x| -3< x \leq 2)[/tex]

Explanation:

Since the point on -3 is hollow, this means that -3 is not included in the equation. Therefore, -3 < x. Since the point on 2 is filled, this means that 2 is a valid number that is included in the equation. Therefore, [tex]x\leq 2[/tex].

Answer:

2,744

Step-by-step explanation:

[tex]C = 400 \sqrt[3]{n} + 200 \\ \\ plug \: C =5800 \\ \\ 5800 = 400 \sqrt[3]{n} + 200 \\ \\ 5800 - 200 = 400 \sqrt[3]{n} \\ \\ 5600 = 400 \sqrt[3]{n} \\ \\ \frac{5600}{400} = \sqrt[3]{n} \\ \\ 14 = \sqrt[3]{n} \\ \\ {(14) }^{3} = {(\sqrt[3]{n})}^{3} \\ (cubing\: both\: sides) \\\\ 2,744 = n \\ \\ n = 2,744[/tex]

[46664792)

Answer:

31°

Step-by-step explanation:

The angle 59° will be equal to the angle c in triangle ABC.

Angle B will be 90°

Angle A + Angle B + Angle C = 180° (ASP)

Angle A + 90° + 59 ° = 180 °

Angle A = 180° - 90° - 59°

Angle A = 31°

Angle A = x

31° = x

Answer:

$52.50

Step-by-step explanation:

Lets use V for Veggie, and H for Ham.

V=4

H=4.50

She is getting 12 sandwiches, and Every 3 H, she buys one V.

So, the order of her buying the sandwiches would be:

H H H V H H H V H H H V

9 H and 3 V

9*H=40.5

3*V=12

40.5+12= $52.50

The total cost of all the sandwiches is given by the equation A = $ 52.50

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total cost of 12 sandwiches be A

Now , the equation will be

For every 1 veggie sandwich 3 ham sandwiches are ordered by Dawn

The cost of veggie sandwich = $ 4.00

The cost of ham sandwich = $ 4.50

So ,

Let the veggie sandwich be = x

Let the ham sandwich be = y

The total number of sandwiches = 12

So , x + 3y = 12

when x = 3 and y = 3

3 + 3 ( 3 ) = 12

3 + 9 = 12

12 = 12

Therefore , the number of veggie sandwich = 3

The number of ham sandwich = 9

And , the cost of 3 veggie sandwich = 3 x 4.00

The cost of 3 veggie sandwich = $ 12

The cost of 9 ham sandwich is = 9 x $ 4.50

The cost of 9 ham sandwich is = $ 40.5

The total cost of 12 sandwich A = cost of 3 veggie sandwich + cost of 9 ham sandwich

Substituting the values in the equation , we get

The total cost of 12 sandwich A = 12 + 40.50

The total cost of 12 sandwich A = $ 52.50

Therefore , the value of A is $ 52.50
