-4x+3y=-2 solving for x and y

Mathematics
1 answer:
NISA [10]3 years ago
7 0

Answer:

y= (-2+4x)/3

x= (-2+3y)/4

Step-by-step explanation:

for y;

3y =  - 2  + 4x

y =  \frac{ - 2 + 4x}{3}

for x;

- 4x = 2 - 3y

- x =  \frac{2 - 3y}{4}

multiply both sides by minus

- ( - x) =  - ( \frac{2 - 3y}{4} )

x =  \frac{ - 2 + 3y}{4}

-1 + 18(-4) 
-1 + -72
-73

A pedestrian bridge is 53 meters long. Due to changes in temperature, the bridge may expand or contract by as much as 21 millime
Katena32 [7]

Length of bridge = 53 meters

Length changes expected due to changes in temperature = expansion or contraction by 21 millimeters (or 0.021 meters)

Let length of bridge at any given time be 'a'

As an absolute value equation, the situation can be expressed as:

⇒ |a-53| < 0.021

Solving the equation

⇒ -0.021 < a-53 < 0.021

⇒ 53 - 0.021 < a < 53 + 0.021

⇒ 52.979 < a < 53.021

Hence, the minimum length of the bridge can be 52.979 meters and the maximum length of the bridge can be 53.021 meters.
