8x+2<3x+12
fastt!!!!!!!!!!!!​

Answer 1

Step-by-step explanation:

Decide whether the lines are parallel, perpendicular or neither.

x + 4y = 7 and 4x – y = 3

Solution:

x + 4y = 7

4y = -x + 7

y = (-1/4) x + 7

Slope of the equation x + 4y = 7 is -1/4.

Again, 4x – y = 3

y = 4x – 3

Slope of the equation 4x – y = 3 is 4.

Since multiplying both the slope of the equation = -1/4 × 4 = -1

Therefore, the given two equations are perpendicular to each other.

Answer: Perpendicular

10. Simplify: 3x – 5 + 23x – 9

Solution:

3x – 5 + 23x – 9

= 3x + 23x – 5 – 9

= 26x – 14

= 2(13x – 7)

Answer: 2(13x – 7)

Answer 2

${\huge{\underline{\boxed{\red{\mathcal{Answer}}}}}}$

Given:

• 8x + 2 < 3x + 12

To Find:

• Values of x

Solution:

$:\implies 8x + 2 < 3x + 12 \\:\implies 8x - 3x < 12 - 2 \\:\implies 5x < 10 \\\bf{:\implies x < 2}$

Hope it helps!
