Solve the inequality.

frutty [35]

Answer:

$\boxed{\boxed{\sf x>-7}}$

Step-by-step explanation:

$\sf -5x-7$

Add 7 to both sides:

$\sf -5x-7+7$

$\sf -5x$

Multiply both sides by -1:

$\sf \left(-5x\right)\left(-1\right)>35\left(-1\right)$

$\sf 5x>-35$

Divide both sides by 5:

$\sf \cfrac{5x}{5}>\cfrac{-35}{5}$

$\sf x>-7$

Find the product of (5x+4)(5x-4)

nydimaria [60]

Answer:

25x² - 16

Step-by-step explanation:

Given

(5x + 4)(5x - 4)

Each term in the second factor is multiplied by each term in the first factor, that is

5x(5x - 4) + 4(5x - 4) ← distribute parenthesis

= 25x² - 20x + 20x - 16 ← collect like terms

= 25x² - 16

18. A lane 180 m long and 5 m wide is to be paved with bricks, of length 20 cm and breadth 150

maksim [4K]

Area of lane=area of rectangle

=180x5=900m²

Area of brick=0.2x0. 15

=0.03m²

No of bricks needed=900/0.03

=30000

Cost of bricks=30000/1000x750

=30x750=22500

How do you complete problem number 4?

brilliants [131]

(I'm going to translate y' to dy/dx as it makes it easier to read for me, you could change it back if you wanted.)
$x \frac{dy}{dx} -y=0$
$\frac{dy}{dx} = \frac{y}{x}$
$\int \frac{1}{y} dy= \int \frac{1}{x} dx$ (separate the variables)
$\ln y=\ln x +c$
$\ln y = \ln kx$ (by letting c = ln k and using log laws)
$y=kx$ (raise everything to power e)
$3=k\times1 \implies k=3$ (applying boundary conditions)
Particular solution: $y=3x$
