The formula for an exponential equation is y = a * b^x with a and b being a fixed value.
"a" would also be the Y intercept, which is where the graph touches or crosses the Y axis. In the given graph, the curved line touches the Y axis at 100, so the value of a would be 100.
Now we need to find b.
The blue dot at Y 50 is lined up with x = 1, so we can use the point (1,50)
Using the X and Y values we can solve for b:
format: y = a * b^x we replace the letters with the numbers above:
50 = 100 * b^1
b^1 = b so now we have:
50 = 100 *b
Divide both sides by 100 to get b by itself:
b = 50/100, which reduces to 1/2, so b = 1/2
So the equation of the graph becomes y = 100(1/2)^x
You may need to write the 1/2 as 0.5, not sure how you need to enter it.
70-q-q-2q= 80
combine like terms first
so you get 70-4q= 80
subtract 70 on both sides and you get -4q= 10
divide -4 on both sides and you get q= 10/-4 or -2.5
Use the trick x+ y+ z =0 and 6+8+z=0,...so z= -14
Answer:
Step-by-step explanation:

Answer : option B
the correct method to label a segment with endpoint E and endpoint F
The endpoints of the line are E and F
The Line starts at E and ends at F. The line will not extend after F
The line having end points are called as line segment
We represent a line segment by putting a line at the top
to label a segment with endpoint E and endpoint F, we use EF or FE and a line at the top
So answer is option B
