Answer:

See below.

Step-by-step explanation:

So we have the equation:

$7m+11=-4(2m+3)$

Distribute the right:

$7m+11=-8m-12$

Add 12 to both sides:

$7m+23=-8m$

Subtract 7m from both sides:

$23=-15m$

Divide by -15:

$m=-23/15\approx-1.5333$

brian invests £4700 into his bank account he recieves 5.5% compound intrest how much will brian have after 3 years?

alexandr1967 [171]

Answer:

Brian will have £817.8

Step-by-step explanation:

Principal = £4700

interest = 5.5% = 0.055

n = 3 years

Amount = [(Principal * (1 + interest)ⁿ) - Principal]

Amount = [(4,700 * (1 + 0.055)³) - 4,700]

Amount = [(4,700 * (1.055)³) - 4,700]

Amount = [(4,700 * 1.174) - 4,700]

Amount = [5,517.8 - 4,700]

Amount = £817.8

Write a linear equation that represents the cost of buying t-shirts from Paula's printing. identify the meaning of each variable

g100num [7]

Answer:

Part 1) $y=x+21.5$

Part 2) $y=x+18$

Step-by-step explanation:

Part 1) Write a linear equation that represents the cost of buying t-shirts from Paula's printing.

Let

x ----> the number of t-shirts

y ----> the cost in dollars

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

take two points from the table

(2,23.5) and (4,25.5)

substitute in the formula

$m=\frac{25.5-23.5}{4-2}$

$m=\frac{2}{2}=1$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=1$

$(x1,y1)=(2,23.5)$

substitute

$y-23.5=(1)(x-2)$

Convert to slope intercept form

$y=mx+b$

$y=x-2+23.5$

$y=x+21.5$

Part 2) Write a linear equation that represents the cost of buying t-shirts from Shantay's shirts.

Let

x ----> the number of t-shirts

y ----> the cost in dollars

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

take two points from the table

(2,20) and (4,22)

substitute in the formula

$m=\frac{22-20}{4-2}$

$m=\frac{2}{2}=1$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=1$

$(x1,y1)=(2,20)$

substitute

$y-20=(1)(x-2)$

Convert to slope intercept form

$y=mx+b$

$y=x-2+20$

$y=x+18$
