You measure two quantities as A=1.0m±0.2m, B=2.0m±0.2m. We should report correct value for

AB

as

Medium

Solution

Correct option is

D

1.4m±0.2m

Here, A=1.0m±0.2m, B=2.0m±0.2m

AB=(1.0m)(2.0m)=2.0m

AB

=

2.0m

=1.414m

Rounding off to two significant figures, we get

Please help me, because they ask for so many characters in Brainly lol

Answer:

y=3x+5

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: y=mx+b where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when the line crosses the y-axis)

Given that the slope is 3, we can plug this into y=mx+b as <em>m</em>:

y=3x+b

Now, to solve for <em>b</em>, simply plug in the given point:

-7=3(-4)+b\\-7=-12+b\\b=5

Therefore, the y-intercept is 5. Plug this back into the equation:

y=3x+5

I hope this helps!
