Answer:

y=8 and

x=2

If x=2, then

8x=8*2=16

so therefore , y=8x i.e 16

y=16

SIMPLE AS THAT !!

You pay $228.50 in taxes at a rate of 10.25% to buy a new TV. How much did the tv cost original? Round your number to the hundre

Allisa [31]

Answer:

$2229.27

Step-by-step explanation:

tax rate: 10.25%

tax amount: $228.50

price before tax: x

10.25% of x = $228.50

0.1025x = 228.5

x = 228.5/0.1025

x = 2229.27

Answer: $2229.27

earth is approximately 9 x 10^7 miles from the sun. neptune is approximately 3x10^9 miles from the sun. neptune is approximately

Gelneren [198K]

Answer:

$33$ times

Step-by-step explanation:

Distance between Earth and the sun $(D)$ = 9 × $10^{7}$ miles = $90,000,000$ miles

Distance between Neptune and the sun $(d)$ = 3 × $10^{9}$ miles = $3,000,000,000$ miles

Find $\frac{d}{D}$ .

$\frac{d}{D}=\frac{3,000,000,000}{90,000,000} =33.3$ ≈ $33$

Therefore,

Neptune is approximately $33$ times farther from the sun than earth

Answer:

G. $y = \frac{1}{2} x + 1$

Step-by-step explanation:

$\because \: line \: m \: is \: passing \: through \: the \: \\ points \: (3, \: 2) \: and \: (4, \: 0) \\ \\ slope \: of \: line \: m = \frac{0 - 2}{4 - 3} = \frac{ - 2}{1} = - 2 \\ \\ \because \: line \: l \perp \: line \: m \\ \\ \therefore \: slope \: of \: line \: l = - \frac{ 1}{slope \: of \: line \: m} \\ \\ \therefore \: slope \: of \: line \: l = \frac{1}{2} \\ \\ line \: l \: is \: passing \: through \: (6, \: 4) \\ \\ \therefore \:equation \: of \: line \: l \: in \: point \: slope \: \\ form \: is \: given \: as \\ \\ y - 4 = \frac{1}{2} (x - 6) \\ \\ y - 4= \frac{1}{2} x - 3 \\ \\ y = \frac{1}{2} x - 3 + 4 \\ \\ \huge \red{ \boxed{y = \frac{1}{2} x + 1}}$
