THREE QUESTIONS WILL GIVE BRAINLIEST
Shkiper50 [21]

1. Answer: To create graphs from verbal expressions, first you have to write the verbal expression as a function. Then, you can create a table of values to look for a pattern and graph the function. The key features of any function can be compared in tables and graphs by creating the matching graph for the function.


2. It is because there is no value of x that will cause the value of f(x) in the formula to equal 0. Notice that the graph crosses the y-axis at 1. ... The inverse of an exponential function is a logarithmic function and the inverse of a logarithmic function is an exponential function


3. y = e^x is an exponential function that increases gradually from (-∞, 0) until it reaches the point (0,1). Thereafter, it very sharply increases on (0,∞).



Hey Can you help me with my questions? I need help for English... and Math!?

Marge purchased bicycle helmets and tire pumps. Each helmet cost $12.00 and each pump cost $8.00. She purchased a total of 18 it
algol [13]

Answer:

11

Step-by-step explanation:

Let the no. of helmet be x

cost of 1 helmet = $12.00

cost of x helmet = $12.00*x = $12x

Let the no. of tire pumps be y

cost of 1 tire pumps = $8.00

cost of x tire pumps = $8.00*y = $8y

Given that total no. of helmet and pump is 18

thus

x + y = 18

y = 18-x

also given

total money spent is $188

thus

12x+8y = 188

using y = 18 - x

we have

12x + 8(18-x) = 188

=> 12x+ 144 - 8x = 188

=> 4x = 188-144 = 44

=> x = 44/4 = 11

Thus, no of helmet bought by Margo is 11.
