We can use a systems of equations to find when the values will equal each other, with x equal to months
Lara's Puppy: 0.5x+3.5
Monica's Puppy: x+2
Now create an equation for these puppy's weights to equal each other, and solve:
0.5x+3.5=x+2
0.5x=1.5
x=3
Answer:
-7/20
Step-by-step explanation:
8/20+-15/20=-7/20
(Ignore the scatter plot thing)
Since the necklace is 33% off, you subtract 33% from 100% to get 67% (you’re only paying 67% of the initial price). You can then multiply 88*0.67 to get the sale price, which is $58.96. For the markdown dollars you can subtract 58.96 from 88 to get $29.04 (you saved $29.04 from the sale)
Answer:
<h2>In the attachment</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
(x₁, y₁) - point
We have the equation:
Therefore we have
the slope m = -2/3
and the point (-9, 5)
A slope
rise = -2
run = 3
From the point (-9, 5) ⇒ 2 units down and 3 units to the right.
Answer:
We can write the position equation as:
P(t) = speed*time + initial position.
If we define Jabal home as the 0 of the position, then Jabal's initial position is 0m
And we know that his speed is 2.5 m/s, then his position equation is:
Pj(t) = (2.5 m/s)*t
We know that Michael speed is 6m/s, and we also know that his house is 15m further away from school than Jabal's one, then Michael's initial position is -15m
Michael's position equation is:
Pm(t) = (6m/s)*t -15 m
The boys will be walking together when they meet, and this will happen when their positions are the same, this means that:
Pj(t) = Pm(t)
That is the equation we need to solve for t.
(2.5 m/s)*t = (6m/s)*t -15 m
15m = (6m/s)*t - (2.5 m/s)*t = (3.5 m/s)*t
15m/(3.5 m/s) = t = 4.28 seconds.
The boys will walk together after 4.28 seconds.
