Answer:y=-6x-10

Step-by-step explanation:

The slope intercept form is y=mx+b

m=slope

b=y intercept

we can find the slope using the slope formula y2-y1/x2-x1

8-(-4)/-3-(-1)

12/-2

m=-6

substitute in the slope, and one of the points so solve for b

y=-6x+b

-4=-6(-1)+b

-4=6+b

b=-10

y=-6x-10

Answer:

y = -6x - 10

Step-by-step explanation:

(-1, -4), (-3, 8)

(x₁, y₁)  (x₂, y₂)

        y₂ - y₁         8 - (-4)          8 + 4         12

m = ------------ = -------------- = ------------ = ------- = -6

        x₂ - x₁          -3 - (-1)         -3 + 1        -2

y - y₁ = m(x - x₁)

y - (-4) = -6(x - (-1))

y + 4 = -6(x + 1)

y + 4 = -6x - 6

   -4            -4

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

y = -6x - 10

Answer/Step-by-step explanation:

Okay, so this question really is a nightmare, because this image is just not possible. Like, literally, Z is or is not the center, you do or do not have enough info. Its a bad question. This is not your fault. If you don't care why its a bad question scroll down to "How could someone get 55°"

If Z is the center, BZ and CZ are radii and equal. Angle CBZ is 60° because

AngleABC + Angle CBZ = 180°

120° + CBZ = 180°

CBZ = 60°

That means AngleC is also 60°. And then, since 180° in a triangle, AngleCZB also must be 60°.

This makes AngleCZD 120°.

But if Z is the center and ArcCD is 115°, then AngleCZD should be 115°.

Contradiction! Angle CZD can't be both 120° and 115° something is wrong here. See image.

How could someone get 55°? Well, it is also not correct but... If ArcCD is 115° then AngleCZD is 115° (if Z is the center) So AngleCZB is 180°-115°, which is 65°.

AngleCBZ is 60°

60° + 65° + C = 180°

125 + C = 180

C = 55°

Answer: The ratio of red marbles to blue marbles is 3:6. This can be written as a fraction as 3/6, which simplifies to 1/2.

Step-by-step explanation:

To find the ratio of two quantities, you can divide the number of one type of item by the number of another type of item. In this case, the ratio of red marbles to blue marbles is 3 marbles / 6 marbles, which simplifies to 1/2.

It's important to note that a ratio is not the same thing as a percentage or a fraction. A ratio is a comparison of two quantities, while a percentage is a measure of a quantity relative to the total amount and a fraction is a division of one number by another.

Answer:

5 hours

Step-by-step explanation:

40=8x

x=5

The number of hours taken for 8 bunnies to eat the same amount of crops will be 5 hours.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

If 5 bunnies can eat all the crops in a garden in 8 hours. The relation between work and time will be inverse. Then the product of the number of bunnies and the number of hours remains constant.

Let 'x' be the number of hours. Then the equation is given as,

8 × x = 5 × 8

Simplify the equation, then we have

8 × x = 5 × 8

8x = 40

x = 40 / 8

x = 5 hours

The number of hours taken for 8 bunnies to eat the same amount of crops will be 5 hours.

Step-by-step explanation:

The magnitude of length BC in the triangle ABC is equivalent to 8.49 units.

Pythagoras theorem states that -

"In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“.

Mathematically, we can write-

[tex]a^2 + b^2 = c^2[/tex]

Given is that ABC is a right triangle, with right angle at B. Side AC has a length of 13 units. Side AB has a length of 5 units.

Using the Pythagoras theorem in the triangle ABC, we get -

AC² = BC² + AB²

BC² = AC² - AB²

BC² = (AC + AB)(AC - AB)

BC² = (13 + 5)(13 - 9)

BC² = 18 x 4

BC² = 72

BC = √(72)

BC = 8.49 units

Therefore, the length of the side BC is equivalent to 8.49 units.

The percentage markdown only affects the price of the baseball bat, not the price of the baseball. Therefore, the price of a baseball will remain the same at $12.

One technique to express a number as a fraction of 100 is through the use of percentage. It is typically used to denote a percentage or share of a larger whole, and it is frequently written with the sign "%." For instance, a student who obtains an 80 is referred to as having gotten a "80%" or "80%".

Percentages can be used to compare distinct numbers, to assess change over time, or to establish the proportion of a group or population that fits into a specific category. For example, a survey may state that 60% of respondents said "yes" to a certain question, or that the price of a product has grown by 10% in the last year.

How to solve.

If the price of a baseball is marked down by the same percentage as a baseball bat, then the price of a baseball will not change.

The percentage markdown only affects the price of the baseball bat, not the price of the baseball. Therefore, the price of a baseball will remain the same at $12.

Start at origin 0,0 make a point

go up 1 and over 2 make a point

connect with straight line  

Point (2,0) is the solution for the inequality y > -3x +2

Here we have,

y > -3x +2

The shaded area above the dotted line is the solution.

We are aware that

If a point is a solution to an inequality, then its coordinates must satisfy the inequality.

We will investigate all cases to find a solution to the problem.

A) Point (0,2)

   Here,

    x = 0

    y = 2

Verify the inequality by changing the values of x and y.

2 > -3 x 0 + 2

2 > 2

It is not correct.

Therefore the point is not to solve the inequality.

B) Point (2,0)

    Here

    x = 2

    y = 0

Verify the inequality by changing the values of x and y.

0 > -3 x 2 + 2

0 > -4

This is correct

Therefore the point is to solve the inequality.

Therefore point B is the solution.

-2/3,  is the slope of the line that passes.

A line's steepness and direction are measured by the line's slope.

Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

Any two different points on a line can be used to calculate the slope of any line.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.

Two locations located on a straight line can be used to determine a line's slope. We can use the slope of line formula if we know the two spots' coordinates. These two points' coordinates should be-

P1 = (x1, y1) and P2 = (x2, y2)

The dimensions of the rectangular prism are:

Length = 4 meters.

Width = 2 meters.

Height = 2 meters.

A rectangular prism of width W, height H, and length L has a volume given by the formula:V = W*H*L

Here we know that: the height and the width are both 2 meters less than the depth, then:W = L - 2H = L - 2 and the volume is 16 cubic meters

Replacing that in the volume equation we will get:16 = L*(L - 2)*(L - 2)It is ratter easy to notice that if we take L = 4, we will get:16 = 4*(4 - 2)*(4 - 2) 16 = 4*(2)*(2)16 = 4*416 = 16 So L = 4 is a solution, then:
