Answer: CAN U MARK BRAINLIST!!!!! You've probably already seen the basic method for graphing straight lines; namely, make a T-chart, plot some points, put your ruler against them, and draw the line. But the "nice" form of a straight line's equation (being the slope-intercept form, y = mx + b) can make graphing even simpler and faster.

Given two points (x1, y1) and (x2, y2), the formula for the slope of the straight line going through these two points is:

\small{ m = \dfrac{y_1 - y_2}{x_1 - x_2} }m=

Slope-Intercept Form

...where the subscripts merely indicate that we have a "first" point (whose coordinates are subscripted with a "1") and a "second" point (whose coordinates are subscripted with a "2"); that is, the subscripts indicate nothing more than the fact that we have two points that we're working with. Note that which point we pick as the "first" point is irrelevant; if we pick the other point to be "first", the subtractions will be reversed, but we'll still get the exact same value for the slope:

\small{ m = \dfrac{y_2 - y_1}{x_2 - x_1} }m=

[tex](x + 5)(x + 2)[/tex]

Use the algebraic identity,

[tex](x + a)(x + b) \\ = {x}^{2} + (a + b)x + ab[/tex]

Now,

a = 5

b = 2

Substitute the values of a & b in the identity & solve the equation.

[tex] {x}^{2} +( a + b)x + ab \\ = x {}^{2} + (5 + 2)x + 5 \times 2 \\ = {x}^{2} + 7x + 10[/tex]

[tex]✎ \: (x + 5)(x + 2) = {x}^{2} + 7x + 10[/tex]

Answer:

B

Step-by-step explanation:

Answer: Y is equal to 1

Step-by-step explanation:

If any variable is by itself like for example 1 + y, that variable would equal one because it's all by itself so it attomatically equals 1. But if the variable was with another number like 1y, then it would mean you have to multiply it by whatever why would equal.

Answer:

A. (x+8)(x+8)

Step-by-step explanation:

F: x*x=x^2

O: x*8=8x

I: 8*x=8x

L: 8*8=64

x^2+8x+8x+64 = x^2+16x+64

Hi there!

I believe your answer is:  

1.5 square meters

»»————-　★　————-««  

Here’s why:  

As given in the question you have asked, the surface area of a cube can be found with:

[tex]SA=6s^2\\\\SA - \text{Surface Area}\\\\S- \text{A given side length.}[/tex]

⸻⸻⸻⸻⸻

We are given the side length of 0.5 meters. This means that we have to substitute the variable 's' for '0.5' to find the surface area.

⸻⸻⸻⸻⸻

[tex]\boxed{\text{Surface Area of a cube with a side length of 0.5 meters:}}\\\\------\\\\SA= 6(0.5)^2\\\\\rightarrow SA=6(0.25)\\\\\rightarrow \boxed{SA=1.5}\\\\------[/tex]

⸻⸻⸻⸻⸻

[tex]\text{The surface area of the cube should be }\boxed{\text{1.5m}^2\text{.}}[/tex]

Answer:

A

Step-by-step explanation:

∠1 is a right angle

Right angles have a measure of 90°

If ∠1 = 117 - y

Then 117 - y = 90

∠2 and ∠3 create a right angle

Like stated previously right angles have measures of 90°

This means that ∠2 + ∠3 = 90

So if ∠2 = 25 and ∠3 = x + 46

Then 25 + x + 46 = 90

The equations created correspond with the answer choice A

Therefore A is the correct answer

Step-by-step explanation:

The question is not properly formatted.

Assume that the given parameter is: 4

Required

The multiplicative inverse

Let a number be x, and the multiplicative inverse be y. The relationship between them is:

[tex]y * x = 1[/tex]

Make y the subject

[tex]y = \frac{1}{x}[/tex]

So;; for the assumed given parameter.

The multiplicative inverse is:

[tex]y = \frac{1}{4}[/tex]

Answer:

768[tex]m^{3}[/tex]

Step-by-step explanation:

Pyramid volume will be base · height over 3

pyramid volume = 64 · 6 / 3

Pyramid volume = 128

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

Prism volume will be base · height

prism volume = 64 · 10

prism volume = 640

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

Now add the sum of the two volumes

640 + 128 = 768[tex]m^{3}[/tex]

Answer:Jonathan is incorrect.

Step-by-step explanation:A quadrilateral has 4 straight sides is a four sided shape which means 4 straight sides.The image you have showed me does not have 4 straight sides nor 4 edges nor 4 verticals.So Jonathan is incorrect.

Answer:

Yes

Step-by-step explanation:

In any triangle, the sum of any two sides must be larger than the third side. To test this, we only actually need to pick the two shorter sides. In this case, the following inequality is true:

[tex]17+37>53,\\54>53,\\\text{True}\:\checkmark[/tex]

Answer:

8:14, 12:27, 40:70

Step-by-step explanation:

Answer: the answer is B: 24ft

Step-by-step explanation: To find how wide the triangle is identify your angles. You have a right angle which is equal to 90° and an angle that measures 46°. Add up both of these angles and you'll get 136°. A triangle can only have three angles that add up to 180. So subtract 180 and 136 you get 44. Multiply the hypotenuse by sin(46) to get the length of the side facing the opposite way of the angle that measures 44°. You will get 11.8 which is about 12. The other triangle is a congruent triangle meaning that it's angles and sides are the same. Add both 12's up and you have 24ft as your width for the cottage.
