Answer:
y = - 
x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - and c = 5 , then
y = - x + 5 ← equation of line
X = -2
explanation: after combining like terms the ends up at 4x = -8 and then divide by 4 on both sides and end up with x = -2
For this case, the first thing you should do is observe the graph.
We have that the x-axis represents the intensity of the sound.
The y-axis represents the measure in decibels.
We have then:
For x = 500 the value of y is y = 28
Answer:
The decibel measurement for the quiet room is:
28 decibels
The answer is 18.8
Just divide 94/5
Step-by-step explanation:
the area of a triangle is baseline×height/2.
the baseline is here 5.8 cm
and the height is given : 2.4 cm
so, the area is
5.8 × 2.4 / 2 = 5.8 × 1.2 = 6.96 cm²
