Answers

Answer:

n = 2

Step-by-step explanation:

Given nx + y = 4, if we rearrange in slope-intercept form: y = -nx + 4

This means that the y-intercept is 4. Point "A" is the y-intercept, which would make OA = 4, and OB = 1/2(4) = 2.

We can now solve for n. The slope here is "-n", also represented by rise/run or OA/-OB = 4/-2 = -2.

-n = -2,

n = 2

0 Example: Loan payments of $400 due 95 days ago and $700 due today
are to be repaid by a payment of $600 thirty days from today and the
balance in 125 days. If money is worth 6% and the agreed focal date is
125 days from today, what is the size of the final payment?​

Answers

Answer:

[tex]X=\$519.48[/tex]

Step-by-step explanation:

From the question we are told that

Loan 1 [tex]X_1=\$400[/tex]

Loan 1 due [tex]t_1=95days[/tex]

Loan 2 [tex]X_2=\$700[/tex]

Loan 2 due[tex]t_2=0days[/tex]

Payment [tex]Y=\$600[/tex]

Worth of money [tex]w=6\%[/tex]

Payment due [tex]t=30days[/tex]

Focal date [tex]t_f=125days[/tex]

Generally [tex]\$400[/tex] was due 95days ago

Therefore

[tex]125+90=220days[/tex](total days to consider)

Therefore

[tex]300+400 =700[/tex] is due today

125days left

Given

600 due in 30days

[tex]125-30=95days[/tex]

Generally the Final payment is mathematically given by

[tex]400(1+ 0.06*\frac{220}{365} ) + 700(1+0.06*\frac{125}{365} )=600(1+0.06*\frac{95}{365} )+X[/tex]

[tex]X=1128.9692 - 609.3698[/tex]

Therefore the

[tex]X=\$519.48[/tex]

Here is a cuboid.

All measurements are in centimetres.

x is an integer.

The total volume of the cuboid is less than
900 cm^3

Show that x < 5.​

Answers

Answer:

Look below

Step-by-step explanation:

-x*3x*2x=6x^3

-6x^3<900

-(cube root both sides)

-6x<9.654893846

-divide by 6

-x=1.609148974

And since 1.609148974 is less than 5, that means that X<5 is correct and hence proved

For given cuboid, x < 5

What is cuboid?

"It is a three-dimensional geometric structure that has six rectangular faces, twelve edges and eight vertices."

Formula of the volume of the cuboid:

V = l × w × h

where, l: length of the cuboid

w: width of the cuboid

h: height of the cuboid

For given example,

We have been given the total volume of the cuboid is less than 900 cm^3

⇒ V < 900 cm³

the length of the cuboid (l) = 3x

the width of the cuboid (w) = 2x

the height of the cuboid (h) = x

Using the formula of the volume of the cuboid,

⇒ V < 900

⇒ l × w × h < 900

⇒ (3x) × (2x) × (x) < 900

⇒ 6x³ < 900

⇒ x³ < 150

⇒ x < 5.3

x < 5

Therefore, for given cuboid, x < 5

D. No, they are not similar.

Answer:

Step-by-step explanation:

<Q is common to both triangles.

130 / 40 = 3.25

Call DQ = x

40/130 = x / (x + 72)       Cross multiply

40*(x + 72) = 130*x

40x + 2880 = 130x      Subtract 40 x from both sides

2880 = 90 x                 Divide by 90

x = 32

(72 + 32)/32 = 104/32 = 3,25

The ratios are the same.

Therefore the triangles are similar by SAS

Lin is solving the inequality 15−x<14. She knows the solution to the equation 15−x=14 is x=1 How can Lin determine whether x>1 or x<1 Is the solution to the inequality?

Answers

Answer:

x > 1

Step-by-step explanation:

Given the inequality ; 15 - x < 14

Since the solution to the equation 15−x=14 is x=1 ;

Then we obtain the value of x for which the inequality expression is true :

If x > 1 ; take x = 2

15 - 2 < 14

13 < 14 (true)

If x < 1 ; take x = 0

15 - 0 < 14

15< 14 (not true)

Hence, solution is x > 1
