Y = -2x + 5
-1: -2(-1) + 5 = 9
1: -2(1) + 5 = 3
3: -2(3) + 5= -1
5: -2(5) + 5= -5

Plot these coordinates on the graph
(-1,9)
(1,3)
(3,-1)
(5,-5)
If the line is straight then it’s linear
If the line has a constant of proportionality the it’s proportional

Use the formula s - 25,000(1.032) to calculate your salary after 6 years. Round your answer to the nearest dollar
aleksandr82 [10.1K]

Answer:

A) $30201

Step-by-step explanation:

The formula S=25000(1.032)^t describes a 3.2% growth in salary for every year where the principal value is $25000 and the time "t" is the amount of years. This is known as exponential growth.

Since t=6:

S=25000(1.032)^6

S=30200.78

Rounded to the nearest dollar is $30201. So A is the correct choice.

emmainna [20.7K]
Hey!!

here is your answer >>>>

If there are 8 students, and who have 3/4 the cake to share equally, we will have to divide 3/4 with 8.

which is( 3/4)/(8)

Now, we will have to take a reciprocal, we get,

(3/4)(1/8)

which is 3/32

which is
Each student gets, 3/32 of the cake!

Hope my answer helps!

Answer:

I. B. true

II. A true

Step-by-step explanation:

we can use the quadratic equation:

x=\frac{-b+-\sqrt{b^{2}-4*a*c}}{2*a}

we have:

1)x^{2} -4x+5

a=1 b=-4 c=5

x=\frac{-(-4)+-\sqrt{(-4)^{2}-4*1*5}}{2*1} \\\\x=\frac{4+-\sqrt{-4}}{2} \\\\x=\frac{4+-\sqrt{4} i}{2}\\\\x=\frac{4+-2i}{2} \\\\x_{1} =2-i\\\\x_{2} =2+i

the quadratic expression has two complex factors.

2)x^{2} -5x+14

a=1 b=-5 c=14

x=\frac{-(-5)+-\sqrt{(-5)^{2}-4*1*14}}{2*1} \\\\x=\frac{5+-\sqrt{-31}}{2} \\\\x=\frac{5+-\sqrt{31} i}{2}\\\\x_{1} =\frac{5-\sqrt{31}i }{2}\\ \\x_{2} =\frac{5+\sqrt{31}i }{2}

the solution of x^{2} -5x+14 are

x_{1} =\frac{5-\sqrt{31}i }{2}\\\\or\\x_{2} =\frac{5+\sqrt{31}i }{2}

3)2x^{2} -8x+5

a=2 b=-8 c=5

x=\frac{-(-8)+-\sqrt{(-8)^{2}-4*2*5}}{2*2} \\\\x=\frac{8+-\sqrt{24}}{4} \\\\x=\frac{8+-2\sqrt{6}}{4}\\\\x_{1} =2-\frac{\sqrt{6}}{2}\\ \\x_{2} =2+\frac{\sqrt{6}}{2}
