castortr0y [4]3 years ago
4 0

Answer:

d)

true

Step-by-step explanation:

- x - 4y = - 10

x + 4y - 10 = 0

a)

3 + 4×2 - 10 = 0

3 + 8 - 10 = 0

11 - 10 ≠ 0 (false)

b)

- 3 + 4×3 - 10 = 0

12 - 3 - 10 = 0

12 - 13 ≠ 0 (false)

Congruent angle pairs : Find value of x
Alexandra [31]

Answer:

(Opt.B) 18

Step-by-step explanation:

4x = 2y - x (vertically opposite angles are equal)

4x + x = 2y

5x = 2y ----- (1)

4x + 2y + x = 180 (Linear pair angles)

5x + 2y = 180

From (1) we can understand that, the value of 5x and 2y is the same. So,

5x + 5x = 180

10x = 180

x = 180/10

x = 18

Just completing,

Putting the value of x in (1)

5*18 = 2y

90 = 2y

90/2 = y

45 = y

Hope you understand

Need help with this ASAP it’s due in 10 minutes
Gennadij [26K]

Answer:

Step-by-step explanation:

Formula to be used,

A = P(1+\frac{r}{n})^{nt}

Here, A = Final amount

P = Principal amount

r = rate of interest

n = Number of compounding (In a year)

t = Duration of investment (In years)

Question (5)

P = $4250

r = 0.015

n = 4

t = 3 years

A = 4250(1+\frac{0.015}{4})^{4\times 3}

A = 4250(1.00375)^{12}

A = $4445.24

Part (C)

1). P = $6000

   r = 0.03

   n = 2

   t = 10 years

  A = 6000(1+\frac{0.03}{2})^{2\times 10}

      = 6000(1.015)^{20}

      = $8081.13

2). P = $9000

    r = 0.05

    n = 2

    t = 8 years

    A = 9000(1+\frac{0.05}{2})^{2\times 8}

        = 9000(1.025)^{16}

        = $13360.55
