1 answer:

3 0

$\text{Turn the equation into slope intercept form}\\\\\text{Slope intercept form: y = mx + b}\\\\\text{Solve:}\\\\x+2y=6\\\\\text{Subtract x from both sides}\\\\2y=-x+6\\\\\text{Divide both sides by 2}\\\\\boxed{y=-\frac{1}{2}x+3}$

PLEASE HELP ASAP, PUT INTO NORMAL NUMBERS, STANDARD FORM?

Masteriza [31]

Given:

The numbers are written in scientific notation.

To find:

The standard form of given numbers.

Solution:

Formula used:

$a^{-n}=\dfrac{1}{a^n}$

(a)

$7.2\times 10^{-8}=7.2\times \dfrac{1}{10^8}$

$7.2\times 10^{-8}=\dfrac{7.2}{1000000000}$

$7.2\times 10^{-8}=0.000000072$

(b)

$6.3\times 10^{-9}=6.3\times \dfrac{1}{10^9}$

$6.3\times 10^{-9}=\dfrac{6.3}{10000000000}$

$6.3\times 10^{-9}=0.0000000063$

(c)

$4.54\times 10^{-5}=4.54\times \dfrac{1}{10^5}$

$4.54\times 10^{-5}=\dfrac{4.54}{100000}$

$4.54\times 10^{-5}=0.0000454$

(d)

$7.041\times 10^{-10}=7.041\times \dfrac{1}{10^{10}}$

$7.041\times 10^{-10}=\dfrac{7.041}{100000000000}$

$7.041\times 10^{-10}=0.0000000007041$

Therefore, $7.2\times 10^{-8}=0.000000072, 6.3\times 10^{-9}=0.0000000063, 4.54\times 10^{-5}=0.0000454,$

$7.041\times 10^{-10}=0.0000000007041$ .

The length of the base of an isosceles triangle is x. The length of a leg is 2x-6. The perimeter of the triangle is 38. Find X

Norma-Jean [14]

Answer:

x = 10

Step-by-step explanation:

Perimeter of a triangle = the sum of the three sides.

In an isosceles the legs are equal (2x - 6) and the base is x

Perimeter = (x) + (2x - 6) + (2x - 6)

38 = 5x - 12

38 + 12 = 5x

50 = 5x

$\frac{50}{5} = \frac{5x}{5}$

10 = x
