What is y+8=-5(x+3) in standard form

Mathematics

Papessa [141]3 years ago

5 0

Answer:

-5x + y = -27

Step-by-step explanation:

Equation: y+8 = -5(x+3)

Standard form is (ax + by = c)

We have to get x and y and their coefficients over to the left side of the equation, and all the single numbers to the right side.

y + 8 = -5 (x + 3)

y + 8 = -5x -15

y = -5x - 27

THE ANSWER IS :

-5x + y = -27

12) You can exchange $5 US dollars for L123 Honduran Lempiras. How many dollars can you exchange L2,300 for? ----

Anit [1.1K]

Step-by-step explanation:

$5 US dollar = L123 Honduran Lempiras

L2300Honduran Lempiras = x ( Let $ be x)

By using chain rule, we get

5×2300 = 123×x

or, 11500 = 123x

or, x = 11500÷123

hence, x = 93.49593496

In isosceles right triangle ABC, point is on hypotenuse \overline{BC} such that \overline{AD} is an altitude of \triangle ABC an

Dmitriy789 [7]

Answer:

Area of triangle is 25.

Step-by-step explanation:

We have been given an isosceles right triangle

Isosceles triangle is the triangle having two sides equal.

Figure is shown in attachment

By Pythagoras theorem

$BC^2=AC^2+AB^2$

AD is altitude which divides the triangle into two parts

DC=5 implies BC =10 since D equally divides BC

Let AC=a implies AB=a being Isosceles

On substituting the values in the Pythagoras theorem:

$10^2=a^2+a^2$

$100=2a^2$

$\Rightarrow a^2=50$

$\Rightarrow a=\pm5\sqrt{2}$

WE can find area of right triangle by considering height AB and AD

Area of triangle ABC is:

$\frac{1}{2}\cdot BC\cdot AD$ (1)

$\Rightarrow \frac{1}{2}\cdot 10\cdot AD$

And other method of area of triangle is:

$\frac{1}{2}\cdot AB\cdot BC$ (2)

Equating (1) and (2) we get:

$\frac{1}{2}\cdot 10\cdot AD=\frac{1}{2}\cdot a\cdot a$

$\Rightarrow AD=\frac{a^2}{10}$

$\Rightarrow AD=\frac{50}{10}=5$

Using area of triangle is: $\frac{1}{2}\cdot BC\cdot AD$

Now, the area of triangle ABC= $\frac{1}{2}\cdot 5\cdot 10$

$\Rightarrow 25$

Rectangle

Viefleur [7K]

Answer:

21 square units

Step-by-step explanation:

The sides of the rectangle are aligned with the coordinate grid, so we can easily find its dimensions.

AB lies on the line y = -2, so the horizontal extent is the difference in x-values:

6 - 3 = 3

BC lies on the line x = 6, so the vertical extent is the difference in y-values:

5 -(-2) = 7

The area is the product of these two dimensions:

A = LW = (7)(3) = 21 . . . . square units

The area of the rectangle is 21 square units.

4(2x + 3) ÷ 5y

Murrr4er [49]

I won’t give a actual answer to the equation, because I want you and anyone else to learn it. but I do want to help!

the sum is the answer to a addition problem. that means you should choose anything that falls under that.

The term is anything that is being separated by + or - so for this, choose anything like that.

The product is the final answer to a multiplication problem.

Factor- any number leading up to a answer in a problem. Example: 3 times 4 is 12. The 3 and the 4 are the factors.

Quotient- the final answer to a division problem.

Coefficient- the number separated from the rest of the problem or the number at the beginning of the problem that stands alone. Because this one is a bit harder to explain, I’ll go ahead and tell you it is 4.

Variable- the unknown number such as y or x.

I hope this helps, and good luck!! :)
