Answer: - 19/4

Step-by-step explanation:

To find the slope , all we need to do is to write the equation in the form y = mx + c , where m is the slope and c is the y - intercept.

That means we need to make y the subject of the formula in the equation.

4y = 152 - 19x

Divide through by 4

y = 152/4 - 19x/4

y = 38 - 19x/4

Therefore the slope is -19/4

Answer:

-4.75

Step-by-step explanation:

Solve for y by dividing by 4:

$y = 38 - 4.75x$

Differentiate with respect to x (use power rule):

$\frac{dy}{dx} = - 4.75$

Answer:

You would multiply the x component by -2

Step-by-step explanation:

(-2) (-2x-5y)=-2(-1)

4x+10y=2

4x+2y=8

set both equal to 4x

4x=2-10y

4x=8-2y

2-10y=8-2y

-6=8y

y=-6/8

y=-3/4

4x + 2(-3/4) = 8

4x=38/4

x=38/16

x=19/8

ANSWER FOR A BUNCH OF POINTS !!EASY!!

Tasya [4]

The correct option is D for the placement of regular polygon and the rhombus.

<h3>What is defined as the regular polygon?</h3>

A polygon is a two-dimensional enclosed image created by connecting three or more straight lines.
A rhombus is a special parallelogram because it meets the definition of a parallelogram, which is a quadrilateral to two pairs of parallel sides.
A polygon is made up of three parts:

Sides: A side is a line segment that connects two vertices.
Vertices: A vertex is the point where two sides meet.
Interior and exterior angles An interior angle is an angle formed by joining the sides of a polygon within its enclosed surface.

As, all the given figures comes under the regular polygon, all are placed in the left circle.

But the three diagram in white, orange and blue colour are regular polygon along with rhombus.

Thus, all three are placed in the intersection of the both circle of the vein diagram.

Write the equation of the line that passes through the two points: (-4, 11) and (2,-4)

snow_tiger [21]

Answer:

y= - $\frac{5}{2}$ x+1

Step-by-step explanation:

Utilize the formula of $\frac{y2-y1}{x2-x1}$ to find the distance between two points, or in this case, the equation of the line that passes through two points.

Applying the given points to identify the slope

1. Plug the coordinates into the y and x values. $\frac{-4-11}{2+4}$ =- $\frac{15}{6}$ .

1.5. Simplify; divide both the numerator and the denominator by 3. - $\frac{5}{2}$ .

Applying slope and a point to find the y-intercept of the equation of a line

1. Utilize the formula of y=mx. Though this sounds strange, morph the sign of equality into subtraction.

1.5. Result: y-mx

2. Do this for both points.

First point: (-4,11)

y-mx

11 + $\frac{5}{2}$ (-4)

11 + -10 (11-10)

Plug the result and the slope into y=mx+b to find the slope of the line.

Result: y=- $\frac{5}{2}$ x+1.

Check your answer to confirm that the value of y is true for both points

1. Do the same thing you did with the first point, but use the second point this time.

y-mx

-4 + $\frac{5}{2}$ (2)

-4 + 5

Plug the result and the slope into y=mx+b to find the slope of the line.

Result: y=- $\frac{5}{2}$ x+1. Identical to point one's result.

In conclusion, both of the results are the same. Therefore, the equation of the line must be y=- $\frac{5}{2}$ x+1.

Think about what you already know about math and baking.

alekssr [168]

Answer:

1. So if you want to know how is math related to baking, I will show you how. Firstly, if you bake a cake, you'll all have to use some measurement, and if you calculate anything wrong or place the crazy amount, the cake you're trying to bake would turn out awful. That's where maths come to play. You would have to calculate ratios and much more, for example, one tee-spoon of sugar to 2 tee-spoons of water it's a 1:2 ratio of sugar to water. If you try to make double the amount of cake, then you'll all have to double the ratio, too, so the ratio will become 2:4, and that's how we would use math in baking a cake. If you for any reason put more than the required amount, the whole cake would be ruined like it might be too sugary, and you will have to retry and bake another one.

2. Yes indeed I've tasted a mess up the cake, and I think that the problem was that the cake batter was much sugary than I expected and that's why you guys have to calculate the perfect amount of ingredients, and that's how maths would help us in baking a cake

hope this helps you btw
