what is ─2c – 2 = ─3c – 8 solved for the variable?

Answers

Answer:

c = -6

Step-by-step explanation:

C is your variable

-2c - 2 = -3c - 8

+3c              +2

1c = c       -8 +2 = -6

c = -6

:)

-2c-2=-3c-8

Add 3c to both sides

-2x+3c-2=-8

Simplify

C-2=-8

Add 2 to both sides

C=-8+2

Simplify

C=-6

Sarah mailed her computer to Store B for repairs. Her bill was:

Initial Repair Cost = $1,350

Sales Tax of 7 percent = $94.50

Total Cost of Computer Repair = $1,444.50

Shipping = 2 percent of Total Cost

Which expression would you use to find the shipping cost?
0.2($1,350)
0.2($1,444.50)
0.02($1,350)
0.02($1,444.50)

Answers

Answer:

0.02 (1444.50)

Step-by-step explanation:

Answer:0.02(1444.50)

Step-by-step:

to figure out the shipping cost we would just multiply the shipping percent by the total cost of the computer. however we cant leave the '2 percent' as it is we would have to multiply it by 100. giving us .02 which we can then use to multiply

Enter an equation in point-slope form for the line. (6,8) and (7,1) is on the line. The equation of the line in point slope form is:

Answers

Answer:

[tex] y - 8 = -7(x - 6) [/tex] or [tex] y - 1 = -7(x - 7) [/tex]

Step-by-step explanation:

The point-slope form equation is [tex] y - b = m(x - a) [/tex], where,

(a, b) = a point on the line.

[tex] m = slope = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Given the two points, (6, 8) and (7, 1), find the slope of the line:

[tex] m = \frac{1 - 8}{7 - 6} [/tex]

[tex] m = \frac{-7}{1} [/tex]

[tex] m = -7 [/tex]

There are two possible point-slope equation we can come up with using each points on the line given.

Using the point (6, 8) and m = -7,

Substitute m = -7, a = 6, and b = 8 into [tex] y - b = m(x - a) [/tex]

[tex] y - 8 = -7(x - 6) [/tex]

Using the point (7, 1) and m = -7,

Substitute m = -7, a = 7, and b = 1 into [tex] y - b = m(x - a) [/tex]

[tex] y - 1 = -7(x - 7) [/tex]

Answers

Given:

The values in the table represent the graph of a continuous function.

To find:

The interval that must contain an x-intercept.

Solution:

From the given table it is clear that, initially y-values are negative but after negative values we get y=0.44 at x=-1.9.

This signs of y-value are different, it means the graph of continuous function must contain an x-intercept in the interval -2.3 < x < -1.9.

Therefore, the correct option is B.

Answer:

Its , -2.3 < x < -1.9

mark is shopping during a computers store 20% sale. He wants to buy computers in the range of $500 to $1000. how much are the computers after 20%

Answers

It's £2000    ( don't have the us money sign sorry )

The cost of computer($1000) after sale is $800.

Given that, a computers store 20% sale. He wants to buy computers in the range of $500 to $1000.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

If cost of computer is $500

Then, 20% of 500 = 0.2×500

= $100

So, after sale the cost of computer is 500-100=$400

Similarly, for other cost as well

If cost of computer is $1000

Then, 20% of 1000 = 0.2×1000

= $200

So, after sale the cost of computer is 1000-200=$800

Therefore, the cost of computer($1000) after sale is $800.

Assume that emergency medical personnel in California are planning for future resources and it has been observed that the average number of traffic accidents requiring ambulance assistance on the Hollywood Freeway between 7 and 8 AM on Wednesday mornings is 1.1. What, then, is the probability that there need for exactly 2 ambulances on the Freeway during that time slot on any given Wednesday morning?

Answers

Answer:

Answer is 0.5

Step-by-step explanation:

The text implies that the number of traffic accidents determines the number of ambulances required on the road. Hence, 1 traffic accident requires 1 ambulance.

The time slot and time of day remain same in both the text and the question.

The average or mean number of accidents is 1.1

QUESTION: What then is the probability that there is need for exactly 2 ambulances on that road and in that time frame?

In other words, what is the probability that there'll be 2 accidents on that road and in that time frame?

Since the mean number of accidents is 1.1,  2 is above the mean.

Probability of 1.1 accidents is 1, since that's the mean (expected value).

Probability of 2 accidents is 1/2 which is = 0.5

use the diagram to solve x and y​

Answers

Answer:

x = 54°

y = 144°

Step-by-step explanation:

x° + 36° = 90° (complementary angles)

Subtract 36° from each side of the equation

x° = 90 - 36°

x = 54°

y° + 36° = 180° (angles on a straight line/supplementary angles)

Subtract 36° from each side

y° = 180° - 36°

y = 144°
