One ordered pair that works is (1,5).

First equation:
5<4(1)+3; 5<4+3; 5<7 This is true

Second equation:
5>-3(1)-3; 5>-3-3; 5>-6 This is also true.

Y < 4x + 3....this will be a dashed line with shading under the line
slope = 4....y int = (0,3)....x int = (-3/4,0)

y > -3x - 3...this will be a dashed line with shading above the line
slope = -3....y int = (0,-3)...x int = (-1,0)

** u can go to desmos calculator to see the graph


one solution is (0,0)
y < 4x + 3...subbing in (0,0)
0 < 4(0) + 3
0 < 3 (correct)

y > -3x - 3...subbing in (0,0)
0 > -3(0) - 3
0 > -3 (correct)

Find the first 5 terms in the sequence an = 2n - 1
JulsSmile [24]

Answer:

1, 3, 5, 7, 9

Step-by-step explanation:

a_n = 2n - 1

n = 1:

a_1 = 2(1) - 1 = 2 - 1 = 1

n = 2:

a_2 = 2(2) - 1 = 4 - 1 = 3

n = 3:

a_3 = 2(3) - 1 = 6 - 1 = 5

n = 4:

a_4 = 2(4) - 1 = 8 - 1 = 7

n = 5:

a_5 = 2(5) - 1 = 10 - 1 = 9

Answer: 1, 3, 5, 7, 9

Write the point-slope form of the line that passes through (6, 1) and is parallel to a line with a slope of -3. Include all of y
denpristay [2]

Answer:

(y - 1) = -3(x - 6)

Step-by-step explanation:

The equation of a line in point-slope form is

(y-y_{1}) = m (x-x_{1})

where y1 and x1 are 2 known points, and m is the slope of the line. So simply just fill in the blanks.

y is a variable so it is left alone (since there is no subscript).

y1 we are told is 1.

m we are told is -3 (the slope)

x is a variable so it is left alone (since there is no subscript).

x1 we are told is 6.

The following function represents the value of a car, in dollars, after x years:
Assoli18 [71]

Answer:

Option D.The decrease in the value of the car, which is 8%

Step-by-step explanation:

we have a exponential function of the form

f(x)=a(b)^{x}

where

y is the value of the car

x is the time in years

a is the initial value

b is the base

r is the rate of decrease

b=1+r

In this problem we have

a=$24,000 initial value of the car

b=0.92

so

0.92=1+r

r=0.92-1=-0.08=-8%-----> is negative because is a rate of decrease

I am not sure how sigma notation works, can somebody explain how to solve this? It isn't the second choice.
Masja [62]

Answer:

first answer is correct

Step-by-step explanation:

Hello, we want to write 2 + 4 + 6 + ... + 20

for n = 1, 2n = 2*1 =2

for n = 2, 2n = 2*2=4

for n = 3, 2n=2*3=6

etc

so

\displaystyle \sum_{n=1}^{10} {2n} = 2*1 + 2*2 +2*3+2*4+...+2*10=2+4+6+8+...+20

thanks
