Answer:
y= -23x+142
Step-by-step explanation:
we know that our equation has to look likethis
y=mx+b
where m is the slope and b is the y intercept
we're given that m = -23 so we have
y= -23x+b
we also know that when x=6 y=4 so we can just plug those values in and solve for b
4= -23(6)+b
142=b
Which means our equation is
y= -23x+142
Answer:
x=wp/5
Step-by-step explanation:
Answer:
t=0 or t=44
Step-by-step explanation:
There are a few methods to do this, the most obvious being the use of the quadratic formula.
However, a quick check with a calculator or even your mind will reveal that 704 is divisible by 16. Thus we can solve this through factoring.
-16t(t-44)=0
Using the zero factor principle:
-16t=0 and so t=0
t-44=0 and so t=44
And thus we get the solution.
Answer:
135°
Step-by-step explanation:
The sum of interior angles in this rectangle is equal to 720
Two of the angles are right (has 90°)
so 4x + 180 = 720 subtract 180 from both sides
4x = 540 divide both sides by 4
x = 135°
