Answer:

(3, 2 )

Step-by-step explanation:

Given the 2 equations

2x + y = 8 → (1)

y = - x + 5 → (2)

Substitute y = - x + 5 into (1)

2x - x + 5 = 8, that is

x + 5 = 8 ( subtract 5 from both sides )

x = 3

Substitute x = 3 into (2) for corresponding value of y

y = - 3 + 5 = 2

Solution is (3, 2 )

A car starts with a speed of 20km/ hr and accelerates at a rate of 3.4 m/s for 20 seconds. What is the final speed of the car in

Schach [20]

The relevant formula that we can use in this situation is:

v = v0 + at

where v is the final velocity, v0 is the initial velocity = 20 km/hr, a is acceleration at 3.4 m/s^2 and t is time at 20 seconds

First convert v0 to m/s, v0 = 5.56 m/s

v = 5.56 m/s + 3.4 m/s^2 * 20 s

v = 73.56 m/s

Then convert back to km/hr:

Couldn’t figure this out help please

WARRIOR [948]

(B)

Step-by-step explanation:

Rewrite the equations into their standard forms. The first one can be rewritten as

$10x - 12y = -5$

and the 2nd can be rewritten as

$3x + 5y = -1$

Solving this system either by substitution or elimination, we get

$x = -\dfrac{37}{86}\:\:\text{and}\:\:y= \dfrac{25}{86}$

If you add x + y, you'll get a negative number.
