Answer:
y = -3x + 5
Step-by-step explanation:
To graph a linear equation in slope-intercept form, we can use the information given by that form. For example, y=-3x + 5 tells us that the slope of the line is -3 and the y-intercept is at (0,5). This gives us one point the line goes through, and the direction we should continue from that point to draw the entire line.
Answer:
C. $240 for 4.5 days.
Step-by-step explanation:
Let's find the answer using the following data:
Notice that the first day is $88 which can be written as:
first day= $38 + $50, in this way the first day cost the same as the other additional days but it include an additional $50 charge.
In this way we can have the formula:
S(x)=38x+50
Notice in the above formula that the '50' represents the extra money for the first day, while '38' the normal cost per day.
Now, S(4.5) needs to be evaluated as S(5) given the condition that a partial day also costs $38, so:
S(4.5)=S(5)=(38*5)+50=240
In conclusion, for 4.5 days the cost is $240, so de answer is C.
G(x)=-2x-4
f(x)=15+0.75x
the common solution Q is their intersection-> calculate x by setting them equal:
-2x-4=15+0.75x
-2x-(3/4)x=19
-(11/4)x=19
x=-4*19/11
x=-76/11
calculate y:
f(-76/11)=15+(3/4)*(-76/11)
=15+(-3*19/11)
=15+(-57/11)
=15+-5-(2/11)
=10-(2/11)
=108/11
so the solution is a) (-76/11, 108/11)
So the formula for area of a triangle is A= 1/2 base x height. SO you do 20 x 30 you get 600. 600/ 2 = 300 so 300 km squared.
The Critical points and the Trig Functions are not really that different than the methods you always use for finding those critical points for any other types of functions and the Critical points are points that the derivative is set as a 0 or it can be undefined.<span />
