y = 4x -3

Find the y-intercept; (0, -3). Plug this coordinate's y-value in for the b (y = mx + b).

Now, find two points on the line to do slope formula, or you can do rise over run. For example, if I had the points (0, -3), and (1, 1), I'd have the formula [1 - (-3)] / (1 - 0), in which the division sign represents a fraction. The simplified version of this fraction will be 4.

Plug this value in for m.

Now, your equation is y = 4x - 3

6)532 with a remainder

BartSMP [9]

Hello Rebelkid2004, 532 with a remainder is, gives remainder 0 and so are divisible by 1, we get factors of 532 numbers by finding numbers that can divide 532 without remainder or alternatively numbers that can multiply together to equal the target number being converted.

LaShaundra is buying fence for two triangular sections of her garden.

mixas84 [53]

Answer: 80 feet.

Step-by-step explanation:

1. As you can see in the figure, triangle ABC and the triangle DFG are similar.

2. The scale of factor of triangle ABC to triangle DFG is the following:

$sf=\frac{20ft}{4ft}\\sf=5ft$

3. Therefore, the lenght of the side DG of the trinagle DFG is:

$DG=5*AC\\DG=5*7ft\\DG=35ft$

4. The perimeter of the triangle DFG is:

$P_{DFG}=20ft+25ft+35ft=80ft$

5. Therefore, she would need 80 feet of fence.

Answer:

ln\frac{(x-3)^5}{x^2}[/tex]

Step-by-step explanation:

First use the exponent property alnb=ln(b)^a

$ln(x-3)^5-ln(x)^2$

Then use the difference property that is lna-lnb= ln(a/b)

$ln\frac{(x-3)^5}{x^2}$

Select the correct answer.

Anit [1.1K]

Answer:

C. 21°

Step-by-step explanation:

In triangle ABC, perpendiculars dropped on the sides AB and AC from the ray BD are equal in measure or congruent.

Therefore, ray BD is equidistant from the sides AB and AC.

So, ray BD will be the bisector of angle ABC.

$\therefore m\angle ABD = m\angle DBC$

(Angle bisector theorem)

$\therefore (3x+9)\degree = (45-6x)\degree$

$\therefore 3x+9 = 45-6x$

$\therefore 3x+6x = 45-9$

$\therefore 9x = 36$

$\therefore x =\frac{36}{9}$

$\therefore x =4$

$\therefore (3x+9)\degree = (3*4+9)\degree=(12+9)\degree =21\degree$

$\implies m\angle ABD=21\degree$
