Write an exponential equation in the form y = ab* whose graph passes through points (2, 18) and (5, 60.75).
DochEvi [55]

Let y=ab^x, as described in the problem statement. Plugging in x=2 and x=5 gives us the equations 18=ab^2 and 60.75=ab^5. Since a,b are nonzero, we divide the second equation by the first to get \frac{27}{8}=b^3, which means that b=\frac{3}{2}, after taking the cube root. Plugging this value for b into the first equation, we now have 18=a(3/2)^2=\frac{9a}{4}. Solving gives a=8, and our desired exponential equation is \boxed{y=8\left(\frac{3}{2}\right)^x}.

I can’t find the answer tried twice probably easy for others
Sloan [31]
Answer: y=-x-2

Slope intercept form is written as y=mx+b, with m being the slope and b being the y intercept.

The slope is negative one. To find the slope, use the formula y1-y2/x1-x2. When you substitute, you may get -4-1/2-(-3). When you solve it, you get -5/5, or -1.

To find the y intercept, look where the line crosses the y axis (vertical line). In the graph, it crosses as -2. Substitute these numbers into the equation and you get y=-1x-2 which can be simplified to y=-x-2.

Restaurant L made 6 dumplings more than Restaurant M.
11Alexandr11 [23.1K]

Answer:

I am not completely sure with this

Step-by-step explanation:

L restaurant=6 + M

N Restaurant= 2 x  L+M

Total dumplings= 72= (6+M) + M + 2x L+M

Dumplings in N restaurant=

suppose m=2

so L= 6+M=8

so L and M will be 10=8+2

N=10 x 2= 20

so u should try and find out like that

Im in elementary school so im not sure
