The graph shows a slope 7/10, which is 0.7. Only 8/11 (=0.72727) is greater than 0.7, so the answer is y=(8/11)x

Answer:

The correct option is 4.

Step-by-step explanation:

The units rate is also knows as slope of the line.

If a line passing though two points then the slope of the lien is

m=\frac{y_2-y_1}{x_2-x_1}

From the given graph it is clear that the line passing through the points (0,0) and (10,7). The slope or unit rate of the given line is

m=\frac{7-0}{10-0}=0.7

The unit rate of the given line is 0.7.

If a equation is defined as

y=mx+b                  .... (1)

then m is the unit rate and b is y-intercept.

By comparing the given options and equation (1),we get

In option 1,

m=\frac{9}{13}\approx 0.69

In option 2,

m=\frac{13}{19}\approx 0.68

In option 3,

m=\frac{11}{16}\approx 0.69

In option 4,

m=\frac{8}{11}\approx 0.72>0.7

In option 5,

m=\frac{7}{12}\approx 0.58

The unit rate of y=\frac{8}{11} is greater than the unit rate of given line, therefore the correct option is 4.

Hal is asked to write an exponential function to represent the value of a $10,000 investment decreasing at 2% annually. What
jek_recluse [69]

Answer:

0.98

Step-by-step explanation:

The investment starts at $10,000.

$10,000 is 100% of the investment.

In the first year, it loses 2% of its value. That means that after 1 year, the value of 100% of $10,000 is decreased by 2% of $10,000.

100% - 2% = 98%

After the first year, the investment is worth 98% of the original value.

98% as a decimal is 0.98

Answer: 0.98

AveGali [126]

Answer:

\displaystyle y = -\frac{x}{5} - 2\frac{1}{5}

Step-by-step explanation:

\displaystyle x + 5y = -11 → 5y = -x - 11 → \frac{5y}{5} = \frac{-x - 11}{5} \\ \\ y = -\frac{1}{5}x - 2\frac{1}{5}

HELP!!!! Find the area. Simplify your answer.<br> 552-9s<br> 3t2+t
Tems11 [23]

Answer:

A = (5s^2t - 9st) (3t + 1)

Step-by-step explanation:

(5s^2 - 9s) (3t^2 + t)

= 15s2t^2 + 5s^2t - 27st^2 - 9st

= 5s2t (3t + 1) - 9st (3t + 1)

= ( 5s^2t - 9st) (3t+1)
