Answer:

x = 4 and y = 2

Step-by-step explanation:

Assuming the figure is a Parallelogram then

Opposite sides are parallel and equal, hence

17x - 64 = x ( subtract x from both sides )

16x - 64 = 0 ( add 64 to both sides )

16x = 64 ( divide both sides by 16 )

x = 4

Also 9y = 2y + 14 ( subtract 2y from both sides )

7y = 14 ( divide both sides by 7 )

y = 2

Solve for x.........

Ket [755]

Answer:

x = 12

Step-by-step explanation:

Angle QPR + Angle PQR = Angle HRQ

$30 + 4x + 2 = 8 + 6x \\ (6 - 4)x = 30 + 2 - 8 \\ 2x = 24 \\ x = 12$

Forty six times y is no more than 276

Step2247 [10]

Answer:

y ≤ 6

Step-by-step explanation:

Step 1: Convert words into an expression

Forty six times y is no more than 276

46 * y ≤ 276

Step 2: Solve for y

46 * y / 46 ≤ 276 / 46

y ≤ 6

Answer: y ≤ 6

Can you please help with this question about exponential equations?

RSB [31]

Since $t$ represents the number of years passed since 2005, in 2005 we have $t=0$ , and in 2015 we have $t=10$ . Let $P_J(y),P_D(y)$ represent the profits of Jones and Davis, respectively, at year y.

We have

$P_J(2005) = 10(0.99)^0 = 10,\quad P_J(2015) = 10(0.99)^{10}\approx 9$

$P_D(2005) = 8(1.01)^0 = 8,\quad P_D(2015) = 8(1.01)^{10}\approx 9$

Choosing the best company somehow depends on how much time you can wait: Jones start with a higher value (10 vs 8), but it has a descending trend, because the multiplicative factor $0.99^t$ goes to zero as t grows.
