Set 4n+3 equal to zero

4n+3=0

4n=-3

n=-3/4

Set 2n-7 equal to zero

2n-7=0

2n=7

n=7/2

and XZ=22

draw a triangle and label its points X,Y,Z.

then fill in your data

Sedaia [141]

Hello:
an equation for the line is : y =mx +b (m: is a slope )

parallel to the liney=2x+2 ( same slope m =2)
the equation is : y =2x+b

through the point (-1,3) : 3 =2(-1)+b....... b=5
the equation is : y = 2x +5

The cost of printing books C varies partly as the amount A charged by the printer

lawyer [7]

The equation connecting C,A and n is C = 25A - $\frac{49990000}{n}$

<h3>What is variation?</h3>

Variation is a mathematical term used to show how a quantity behaves when one quantity increases or decreases.

Analysis:

C = AK + M/n

where K and M are constants

when n = 1000, A = 5000, C = 75010

75010 = 5000K + M/1000-----------1

50004 = 10000k + M/200-------------2

solving simultaneously, K = 25, M = -49990000

C = 25A - 49990000/n

In conclusion, the equation connecting C,A and n is C = 25A - 49990000/n

Answer:

Monthly pay = int. rate / 12 months * cost of car after downpayment / (1-(1+ int. rate/12 months)^( - term length of loan )

Step-by-step explanation:

Just plug in your numbers:

M = 0.0375/12 * 30000/(1-(1+.0375/12)^60)

since 5 years is 60 months

PLEASE HELP ASAP<br> trigonometry

Alex73 [517]

Answer:

5). x = 11.9°

6). x = 27.2°

Step-by-step explanation:

5). By applying cosine rule in the given triangle,

cos(32)° = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

cos(32)° = $\frac{x}{14}$

x = 14cos(32)°

x = 11.87

x ≈ 11.9°

6). By applying sine rule in the given triangle,

sin(54°) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

sin(54°) = $\frac{22}{x}$

x = $\frac{22}{\text{sin(54)}}$

x = 27.19°

x ≈ 27.2°
