Order the numbers from greatest to least. [-0.5, 1.5, 0, -5, 1.25]
DiKsa [7]

Answer:

d. 1.5, 1.25, 0, -0.5, -5

Step-by-step explanation:

1.5 > 1.25 > 0 > -0.5 > -5

Well it is obvious that 1.5vis greater than 1.25.

0 is greater than any negative integers, and that the higher negative number it's value is lower. For example:

-10,000 is less than -100

-4 is greater than -10

3. How much interest does $5300 earn at a rate of 2.8% interest compounded quarterly after 6
azamat

Answer:

The interest is I=\$74.46

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=6/12=0.5\ years\\ P=\$5,300\\ r=0.028\\n=4  

substitute in the formula above  

A=5,300(1+\frac{0.028{4})^{4*0.5}

A=5,300(1.007)^{2}  

A=\$5,374.46  

<em>Find the interest</em>

I=A-P

substitute

I=\$5,374.46-\$5,300=\$74.46

A line contains the points (-4,5) and (3,-9). Write the equation of the line using slope-intercept form..please hurry
kotegsom [21]

Answer:

y= -2x-3

Step-by-step explanation:

Using the slope intercept form we have to first find the gradient of the line.

m=(y₂-y₁)/(x₂-x₁)

y₁=5

y₂=-9

x₁=-4

x₂=3

Therefore, m= (-9-5)/(3--4)

=-2

Therefore if we pick any point on the line, say, (-4,5) we obtain the same slope.

(y-5)/(x--4)=-2

(y-5)/(x+4)=-2

y-5=-2(x+4)

y-5=-2x-8

y= -2x-3

Thus the equation of the line in the slope intercept form is: y= -2x-3
