What are the values of x in the equation x(x-6)=4(x+6)

1 answer:

7 0

x(x-6) = x^2 - 6x 4(x+6) = 4x + 24 First we need to eliminate the bracket by multiplying the numbers and variables from outside the bracket with the inside, we weill get : X^2 - 6x = 4x + 24 (subtract 4x and 24 from both sides) x^2 - 10x - 24 = 0 (x+2) (x-12) = 0 x+2 = 0 x-12 = 0 The value of X would be : x = -2 x = 12

Which of the following graphs shows the solution for the inequality y-4> 2(x+2)?

timofeeve [1]

Answer:

Answer:

Graph C shows the solution for the inequality

Step-by-step explanation:

y - 4 > 2(x + 2)

y > 2x + 4 + 4

y > 2x + 8

Let y = 2x + 8, Then

X-intercept (0, 8)

Y-intercept (-4, 0)

Since the inequality sign is > we use broken line.

Put, (0, 0)

y > 2x + 8

0 > 0+ 8

0 > 8 Which is false

so, the answer will be above the broken line

Hence , Graph C shows inequality

Solve the inequality -6p<12 Ah this is due by tomorrow

777dan777 [17]

-6p < 12 Divide -6 on both sides to get "p" by itself

$\frac{-6p}{-6} < \frac{12}{-6}$

p > -2

When you divide or multiply a negative number to both sides of the inequality, the sign (< , > , ≤ , ≥) is flipped.

Answer:

r = 2.5

Step-by-step explanation:

the area of the whole circle = $\frac{13}{50}$ *π * 24

A = πr² = (13π*24)/50

r = √((13*24)/50) = 2.5 inches
