Answer 1

Answer:

Answer:

1; -1

Step-by-step explanation:

As x approaches 0 from the left, the graph goes up to the point (0, 1), where the solid dot indicates that is the function definition for x=0.

As x approaches 0 from the right, the graph goes down toward the point (0, -1), to which it comes arbitrarily close. The limit from that direction is -1.

The two limits are +1 and -1.

Jessica is selling books during the summer to earn money for college. She earns a commission on each sale but has to pay for her own expenses. After a month of driving from neighborhood to neighborhood and walking door-to-door, she figures out that her weekly earnings are approximately a linear function of the number of doors she knocks on. She writes the equation of the function like this: E(x) = 20x - 50, where x is the number of doors she knocks on during the week and E(x) is her earnings for the week in dollars.What does the slope of Jessica's function represent?a. For each additional set of books she sells, her earnings will increase by $20.b. For each additional door she knocks on, her earnings will increase by $20.c. For each additional set of books she sells, her earnings will increase by $50.d. For each additional door she knocks on, her earnings will increase by $50.

Solve for d.5d+2(2-d)=3(1+d)+1
a)no solution
b)d=4
c)infinitely many solutions
d)d=-3

Answers

5d + 2(2 - d) = 3(1 + d) + 1
5d + 2(2) - 2(d) = 3(1) + 3(d) + 1
5d + 4 - 2d = 3 + 3d + 1
5d - 2d + 4 = 3d + 3 + 1
3d + 4 = 3d + 4
-3d    -3d
   4 = 4
   d = 0

$5d+2(2-d)=3(1+d)+1 \n 5d+4-2d=3+3d+1 \n 3d+4=3d+4 \n 0=0 \n \boxed{C.\ Infinitely\ many\ solutions}$

your school sells tickets for its winter concert. Student tickets are $5 and adult tickets are $10. If your school sells 85 tickets and makes $600, how many of each ticket did they sell?

Answers

Let s be the number of student tickets and a be the number of adult tickets.
s + a = 85; a = 85 - s
Also,
5s + 10a = 600

Substituting a from the first equation
5s + 10(85 - s) = 600
-5s = -250
s = 50
a = 85 - 50 = 35
The school sold 50 student tickets and 35 adult tickets.

A line has this equation: y= -9x-2Write an equation for the parallel line that goes through (2, -3).

Answers

Answer:

y = - 9x + 15

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 9x - 2 ← is in slope- intercept form

with slope m = - 9

Parallel lines have equal slopes, thus

y = - 9x + c ← is the partial equation

To find c substitute (2, - 3) into the partial equation

- 3 = - 18 + c ⇒ c = - 3 + 18 = 15

y = - 9x + 15 ← equation of parallel line
