-17 -5(X+3) = 3x solve

1 answer:

3 0

-17 -5 (x + 3) = 3x Use the Distributive Property
-17 -5x - 15 = 3x Combine like terms (-17 and -15)
-32 - 5x = 3x Add 32 to both sides
-5x = 3x + 32 Subtract 3x from both sides
-8x = 32 Divide both sides by -8
x = -4

On a very cold morning, it was -7°F. As the day went on, the temperature rose 3 degrees each hour. Which equation shows the temp

wariber [46]

Answer:

The equation shows the temperature over time will be:

$y = 3x - 7$

Hence, option (C) is correct.

Step-by-step explanation:

We know that the slope-intercept form of the line equation is

$y=mx+b$

where m is the rate of change or slope and b is the y-intercept

Let 'y' be the temperature

Let 'x' be the time in the hour

Given that one very cold morning, it was -7°F.

Thus, the y-intercept = b = -7

Given that as the day went on, the temperature rose 3 degrees each hour.

Thus, the rate of change = slope = m = 3

Thus, substituting m = 3 and b = -7 in the equation

$y = mx+b$

$y = 3x + (-7)$

$y = 3x - 7$

Therefore, the equation shows the temperature over time will be:

$y = 3x - 7$

Hence, option (C) is correct.

Last question of the day for 20 points :)

Jobisdone [24]

When x=0, y=4...

Therefore:

4=a*b⁰

b⁰=1, so a=4.

----------

When x=1, y=2...

Therefore:

2=4*b¹

4b=2

b=2/4

So... b=1/2.

This means that:

y=4*((1/2)^x)
