Well the equation of this line is 
. Which means that for any value of y the x will always equal to 3/5, so the points (ordered pairs) for eg. are 
.
Hope this helps.
A is 11 and b is 16. for b you would plug in what you got for a for x
Answer:
The slope <em>m</em> is 1.9 and the y-intercept <em>b</em> is 2.5.
Step-by-step explanation:
This is in slope-intercept form, y=<em>m</em>x+<em>b</em>, where <em>m</em> is slope and <em>b</em> is the y-intercept.
y = 1.9x + 2.5 means that <em>m </em>is 1.9 and <em>b</em> is 2.5.
Exponential rules state that when you divide exponents, you subtract by the powers. The powers have the same coefficients, so you can divide the two numbers.
6 - (-3) = 9
The answer is
.
Answer:
t=+4.06
Step-by-step explanation:
when the baseball hits the ground, the height will be 0.
h=0we are given that h=−16t2+64t+4.
this means that the height is 0 when −16t2+64t+4=0.−16t2+64t+4=0divide both sides by 4:−4t2+16t+1=04=0−4t2+16t+1=0 can be solved using the quadratic formula:t=−b±√b2−4ac2a, where at2+bt+c=0.at2+bt+c=−4t2+16t+1a=−4,b=16,c=1t=−b+√b2−4ac2aor−b−√b2−4ac2a−b+√b2−4ac2a=−16+√272−8=−0.06..−b−√b2−4ac2a=−16−√272−8=4.06 (3s.f.)we have 2 values for t:−0.06 and 4.06.
since time cannot be negative, only the positive value can be taken.
this is 4.06, to 3 significant figures.the time taken is 4.06 seconds.
