Answer:

the cost of the table is \$165

the cost of the chair is \$125

Step-by-step explanation:

Let

x-----> the cost of the table

y----> the cost of the chair

we know that

2x+3y=705 -----> equation A

x=y+40 -----> equation B

substitute equation B in equation A

2(y+40)+3y=705

2y+80+3y=705

5y=705-80

y=625/5

y=\$125

Find the value of x

x=y+40  ----> x=125+40=\$165

Trella alcala deposited 1,950 in a new credit union savings account on the first of the quarter the principal earns 4.25 percent
mrs_skeptik [129]
Amount in compound interest = p(1 + r/t)^nt where p is the initial deposit, r = rate, t = number of compunding in a period and n = period.

Here, Amount after 6 months (0.5 year) = 1,950(1 + (4.25/100)/4)^(0.5 x 4) = 1,950(1 + 0.0425/4)^2 = 1,950(1 + 0.010625)^2 = 1,950(1.010625)^2 = 1,950(1.0213629) = $1,991.66

Compound interest = Amount - principal (initial deposit) = $1,991.66 - $1,950 = $41.66

Please help!!! What is the equation of the line in slope-intercept form? Write your answer using integers, proper fractions, and
BabaBlast [244]

Answer:

y = x - 40

Step-by-step explanation:

Points on the graph: (0, -40) and (60,20)

Slope:

m=(y2-y1)/(x2-x1)

m=(20+40)/(60-0)

m=60/60

m = 1

Slope-Intercept

y - y1 = m(x - x1)

y + 40 = 1(x -0)

y + 40 = x

y = x - 40
