Find an equation of the line passing through the point (-4,6) that is perpendicular to the line y=7/2x+5. Work please.

kondaur [170]

Answer:

y = $-\frac{2}{7}$ x + 4 $\frac{6}{7}$

Step-by-step explanation:

We are to find the equation of line 1 which passes through point (-4,6)

Line 1 is perpendicular to line 2.

The equation of line 2 is; y = $\frac{7}{2}$ x + 5

The slope of line 2 is $\frac{7}{2}$

Because the product of two perpendicular line is -1;

The slope of line 1 is -1 ÷ $\frac{7}{2}$ = $\frac{-2}{7}$

Taking another point (x,y) on line 1;

Slope = change in y ÷ change in x

$\frac{-2}{7}$ = $\frac{y - 6}{x - -4}$

y - 6 = $\frac{-2}{7}$ (x + 4)

y - 6 = $\frac{-2}{7}$ x - $\frac{8}{7}$

y = $\frac{-2}{7}$ - $\frac{8}{7}$ + 6

y = $-\frac{2}{7}$ x + 4 $\frac{6}{7}$

(a + b)² = a² + 2ab + b2 with step by step explanation

Dahasolnce [82]

Step-by-step explanation:

Given: (a+b)²

To prove: (a+b)² = a² + 2ab + b²

Proof:-

(a+b)² = (a+b)(a+b)

(a+b)²=a(a+b)+b(a+b)

(a+b)² = a²+ab+ab+b²

(a+b)² = a²+2ab+b².

what is the relationship between 5.34 x 10^5 and 5.34 x 10^-2 is it greater or lesser than? for 5.34 x 10^5? will give brainlies

Romashka-Z-Leto [24]

the relationship between 5.34 x 10^5 and 5.34 x 10^-2

$5.34 x 10^5 = 5.34*100000= 534000$

5.34 * 10^-2 , for exponent -2 we move the decimal point 2 places to the left

$5.34 x 10^-2= 0.0534$

Now we compare 534000 and 0.0534

0.0534 is 10,000,000 times less than 534000

Or we can say 534000 is 10,000,000 times greater than 0.0534

$5.34 x 10^5$ is 10,000,000 times greater than $5.34 x 10^-2$
