The equation of the line that contains the points (-8, 1) and (0, -5) is

Mathematics
1 answer:
posledela3 years ago
5 0

Answer:

y = -3/4x -5 (G)

Step-by-step explanation:

Find the slope by using the slope formula. (It's hard to format here so look it up)

Basically, it is y2 - y1/x2 - x1

-5 - 1/ 0 + 8

-6/8 = -3/4

The slope is -3/4.

Plug in for y = mx + b

y (y coordinate) = -5

x (x coordinate) = 0

slope (m) = -3/4

-5 = -3/4(0) + b

-5 = 0 + b

b = -5

y = -3/4x -5

g A jacket regularly sells for $135.00. The sale price is $60.75. Find the percent decrease of the sale price from the regular p
Alenkasestr [34]

Answer:

55%

the percent decrease of the sale price from the regular price is 55%

Step-by-step explanation:

Percentage decrease is the percentage change in the sales price (regular and new)

Percentage decrease %∆P = ∆P/Pr × 100%

∆P = change in sales price = $135 - $60.75

Pr = regular price = $135

Substituting the values;

%∆P = (135-60.75)/135 × 100%

%∆P = 55%

the percent decrease of the sale price from the regular price is 55%

The first term of a geometric sequence is 300 and the common ratio is 2 What is the 7th term of the sequence
xxMikexx [17]

Step-by-step explanation:

s1 = 300

s2 = s1 × 2 = 300 × 2 = 600

s3 = s2 × 2 = s1 × 2² = 1200

sn = sn-1 × 2 = s1 × 2^(n-1)

s7 = 300 × 2⁶ = 300 × 64 = 19,200

Find the percent of increase to the nearest whole from 12 to 20
ankoles [38]

Answer:

The answer is

<h2>67\%</h2>

Step-by-step explanation:

To find the percentage increase we use the formula

<h3>Percentage \:   change =  \frac{change}{original \:  \: quantity}  \times 100\%</h3>

From the question

The original value = 12

To find the change we subtract the smaller value from the larger one

That's

Change = 20 - 12 = 8

So the percentage increase is

<h3>\frac{8}{12}  \times 100 \%\\  =  \frac{2}{3}  \times 100\% \\  = 66.67\%</h3>

We have the final answer as

67\% to the nearest whole number

Hope this helps you
