We are given linear equation y=−0.7x−28.
We need to find the coordinates of its intersection with the x- and y-axes.
<em>Note: The coordinate at which line intersect x-axis is called x-intercept and The coordinate at which line intersect y-axis is called y-intercept.</em>
In order to find y-intercept, we need to plug x=0 and solve for y.
Plugging x=0
y= −0.7(0)−28 = 0-28 = -28.
<h3>Therefore, the coordinate where line intersect y-axis is (0,-28).</h3>
In order to find x-intercept, we need to plug y=0 and solve for x.
Plugging y=0
0 = −0.7x−28
Adding 28 on both sides, we get
0+28 = −0.7x−28+28
28 = -0.7x
Dividing both sides by -0.7, we get
x=40.
<h3>Therefore, the coordinate where line intersect x-axis is (40,0).</h3>
An Acute angle
less than 90*= acute angle
Answer:
A=20,000 m2 per year
Step-by-step explanation:
we have that Volume (V) =300,000 m3, so V=A*h, where A=area (m2) and h=15m
V=A*h ⇒ 300,000m3=A*15m ⇒ A=300,000m3/15m ⇒ A=20,000 m2
Answer: 20% decrease.
<u>Step-by-step explanation:</u>
The negative sign represents a decrease.
Answer:
8000
Step-by-step explanation:
10000 x 20% = 2000
10000-2000= 8000
