For the function f(x) = 2x-5 find.<br>a. f(2) <br>b. f(0) <br>c. f(-3)

anastassius [24]

Answer:

a. f(2) :

$f(x) = 2x - 5 \\ f(2) = 2(2) - 5 \\ f(2) = 4 - 5 \\ f(2) = - 1$

b. f(0) :

$f(x) = 2x - 5 \\ f(0) = 2(0) - 5 \\ f(0) = - 5$

c. f(-3) :

$f(x) = 2x - 5 \\ f( - 3) = 2( - 3) - 5 \\ = - 6 - 5 \\ = - 11$

A roller coaster starts from a deck at an elevation of 20 feet above the ground. On the first hill it climbs 83 feet and then dr

Simora [160]

Initially started 20 feet from the ground .
Went uphill 83 feet.
So: 20 + 83 = 103. The coaster is 103 ft above at this point.

Went down 42 feet
So: 103 - 42 = 61.

Went up 128 feet
So: 61 + 128 = 189

Finally, went down 90 feet
So: 189 - 90 = 99

99 ft above ground.

Ryan the trainer has two solo workout plans that he offers his clients: Plan A and Plan B. Each client does either one or the ot

Ivahew [28]

Answer:

Both plans last for 1.25 hours (1 hour 15 minutes)

Step-by-step explanation:

Let x hours be the time needed for plan A and y hours be the time needed for plan B.

On Wednesday there were 5 clients who did Plan A and 3 who did Plan B. Thus, 5x+3y=10.

On Thursday there were 2 clients who did Plan A and 6 who did Plan B. Thus, 2x+6y=10.

Solve the sytem of two equation. Multiply the first equation by 2, the second by 5 and subtract them:

$10x+6y-10x-30y=20-50,\\ \\-24y=-30,\\ \\y=\dfrac{30}{24}=\dfrac{5}{4}=1.25\ hours.$

Therefore,

$5x+3\cdot 1.25=10,\\ \\5x=10-3.75=6.25,\\ \\x=1.25\ hours.$
