Find the slope of the line Y=-3x - 4

1 answer:

6 0

Let y=0 to find the x-intercept(s).
0=−3x−4

Add 4 to both sides.
4=−3x

Divide both sides by -3
-4/3 =x (fraction)

Switch sides.
x=−4/3 (fraction)

Let x=0 to find the y-intercept(s).
y=−3×0−4

Simplify
y=−4

Softa [21]

Answer:

62 cm

Step-by-step explanation:

Given the expressions for width (3x + 1) and length (5x - 2) as well as the formula for the perimeter of a rectangle: 2(5x - 2) + 2(3x +10), we can first solve for the simplified expression of 'x' and then substitute the given value of x = 4cm to find the total distance:

Distribute: 2(5x - 2) + 2(3x +1) = 10x - 4 + 6x + 2

Combine like terms: 16x - 2

Plug in '4' for 'x': 16(4) - 2 = 64 -2 = 62 cm

Nine less than one forth of a number is 6

snow_lady [41]

Answer:

$x = 60$

Step-by-step explanation:

Step 1: Convert into an equation

Nine less than one forth of a number is 6

$1/4x - 9 = 6$

Step 2: Add 9 to both sides

$1/4x - 9 = 6$

$1/4x - 9 + 9= 6+ 9$

$1/4x = 15$

Step 3: Multiply both sides by 4

$1/4x * 4 = 15 * 4$

$x = 60$

Answer: $x = 60$

A chemist has 10% and 40% solutions of acid available. How many liters of each solution should be mixed to obtain 120 liters of

kaheart [24]

Answer:

100 liters of 10% solution is used and 20 liters of 40% solution is used

Step-by-step explanation:

Let "X" amount of 10% solution is used. Then the amount of 40% solution used is equal to 120-X

Now

10% of X + 40% of (120-X) = 15% of 120

On solving the above equation, we get

$0.1 X + 0.4 (120-X) = 0.15 *120\\0.1 X + 48 -0.4X = 18\\0.3 X = 30\\X = 100$ liters

Amount of 40% solution used = 120 -X = 120-100 = 20 liters

100 liters of 10% solution is used and 20 liters of 40% solution is used
