3 0

Answer:

One solution: x=2.4, y=0.2

Step-by-step explanation:

x-2y=2

y=-2x+5

x-2(-2x+5)=2

x+4x-10=2

5x=2+10=12

x=12:5=2.4

y=-2x+5=-2*2.4+5=-4.8+5=0.2

I am Lyosha [343]

2x + 2y = 20
2(6) + 2y = 20
12 + 2y = 20
2y = 8
y = 4
width = 4

Area = 6 × 4
= 24 cm

The velocity of a car increases from 4 m/s at 2 sec. To 32 m/s at 9 sec. What is the car’s average acceleration?

Dahasolnce [82]

Answer:

$a=4\ m/s^2$

Step-by-step explanation:

Given that,

The velocity of a car increases from 4 m/s at 2 sec to 32 m/s at 9 sec.

We need to find the car's average acceleration. It can be given by the change in velocity divided by the change in time. So,

$a=\dfrac{v-u}{t_2-t_1}\\\\a=\dfrac{32-4}{9-2}\\\\a=4\ m/s^2$

So, the car's average acceleration is equal to $4\ m/s^2$ .
