Answer:
The equation of this line is y = -3x + 7
Step-by-step explanation:
Remember that when writing an equation for a graphed linear line, we must write it in slope intercept form (y=mx+b). The m represents the slope, and the b represents the y-intercept.
<em>(</em><em>The slope determines the direction in which the line </em><em>goes</em><em>,</em><em> </em><em>and</em><em> </em><em>is</em><em> </em><em>written</em><em> </em><em>as</em><em> </em><em>rise</em><em>/</em><em>run</em><em>.</em><em>)</em>
In this case the slope is going to be negative, since the line is going downwards to the right. Additionally the slope of this line is -3/1 or just -3.
<em>(</em><em>The</em><em> </em><em>y</em><em>-</em><em>intercept</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>point</em><em> </em><em>in</em><em> </em><em>which</em><em> </em><em>the</em><em> </em><em>line</em><em> </em><em>crosses</em><em> </em><em>the</em><em> </em><em>y</em><em>-</em><em>axis.</em><em>)</em>
In this case, since the line crosses the y-axis at positive 7, the y-intercept will be 7.
So all together we have y = -3x + 7.
Hope this helps you :)
Answer:
6 cars per hour
Step-by-step explanation:
The rate can be expressed several ways. One of them is "cars per hour". To find that rate, divide cars by hours:
(24 cars)/(4 hours) = 6 cars/hour
__
If 6 cars were washed in 60 minutes, another way to express the rate is ...
(60 minutes)/(6 cars) = 10 minutes/car
__
When you ask "what is the rate?", you need to be specific as to the rate you're interested in. Different expressions of the rate are useful for different purposes.
now, the hypotenuse is just a radius unit, so, is never negative, so, the fraction is negative because the numerator is negative, that is, the adjacent side is -3.
now, let's use the pythagorean theorem to find the opposite side.
ok... so, which is it? the +/-? well, we also know that <span>sin(t) >0, namely that the sine of the angle is positive, so, then is +4 then.

Answer:
6 - pack of scented candles for $40.5?
Step-by-step explanation:
$30 ÷ 4 = $7.5 for one
$40.5 ÷ 6 = $6.75 for one
therefore 6 - pack of scented candles for $40.5 is more cheap.
Answer:
Part 1)
Part 2) There are about
Step-by-step explanation:
Part 1) we know that
1 month=4 weeks
Let
x------> the number of hours of practice for three months
so
Convert months to weeks
3 months=3(4)=12 weeks
using proportion
that means------> In three months (12 weeks) the pianist practice 180 hours
Part 2)
Let
x------> the number of bass
y------> the number of catfish
we know that
Using proportion
There are about
