Find the slope and y-intercept of the line 6x−7y=2

1 answer:

Allisa [31]3 years ago

To easily find the slope and y intercept of the line, put it in slope intercept form by rearranging the variables around.

6x-7y = 2
6x - 7y + 7y = 2 + 7y
6x = 7y + 2
6x - 2 = 7y + 2 - 2
7y = 6x - 2
7y/7 = 6x/7 - 2/7
Y = 6/7(X) - 2/7

Y = 6/7x - 2/7
Slope = m = 6/7
Y intercept = b = -2/7
(0, -2/7).

Answer:

$11. - 60 = - 49 \\ 12.10 = 12.1 \\ 13. - 9 = 4 \\ 14.14 = \frac{707}{50} \\ 15.37 = \frac{1537}{100}$

Coffee table is 20% odd the original price of $115. If there is 7.5% sales tax, what is the final price of the coffee table?

netineya [11]

100%-20%= 80%=0.8

115(0.8)= 92

92(1.075)= 98.9

The final price of the coffee table is $98.90.

Hope this helps!

Answer:

Not proportional

Step-by-step explanation:

If x and y are proportional then the equation relating them is

y = kx ← k is the constant of proportionality

To determine if x and y are in proportion then k must be equal for all ordered pairs, that is

k = $\frac{y}{x}$

(2, 0) k = $\frac{0}{2}$ = 0

(4, 2) → k = $\frac{2}{4}$ = $\frac{1}{2}$

(6, 4) → k = $\frac{4}{6}$ = $\frac{2}{3}$

(8, 6) → k = $\frac{6}{8}$ = $\frac{3}{4}$

Since k is not constant for all values then not in proportion

The following are the last 10 run scores Colin got in cricket: 23, 20, 4, 19, 28, 35, 25, 0, 1, 30 a) Work out Colin's mean scor

sdas [7]

Answer:

I have given it step by step below.

Step-by-step explanation:

(i) Mean = sum of observations/total no. of observation

= 23 + 20 + 4 + 19 + 28 + 35 + 25 + 0 +1 + 30/ 10

= 185/10

= 18.5

(ii) additional 35 runs

New Mean

=previous total + 35/10 + 1 (the 1 gets added in denominator because of the additional observation)

= 185 + 35/11

= 220/11

= 20

Hope this helps you!
