1. Solve the system of equations by substitution:
y = x - 2
4x – 3y = 11

Answers

Answer:

x = 5

y = 3

Step-by-step explanation:

y = x - 2

4x - 3y = 11

substitute y in the second equation with x - 2

4x - 3(x - 2) = 11

open the parenthesis

4x - 3x + 6 = 11

x + 6 = 11

subtract 6 from both sides of the equation

x + 6 - 6 = 11 - 6

x = 5

now substitute x for 5 in the original equation.

y = x - 2

y = 5 - 2

y = 3

At a local pumpkin patch you can pick your own pumpkins. There is a $5 charge to enter the patch and then a $0.25 charge per pound of pumpkin. Let p
represent the weight of the pumpkin you choose and C(p)
represent the total cost of the pumpkin in terms of the weight of the pumpkin. Equation, in function notation:

Answers

Answer:

C(p) = 0.25p + 5

Step-by-step explanation:

$5 is the amount of money you have to pay when you don't get a pumpkin (a pumpkin that's 0 lbs), so the y-intercept is 5. 0.25 is the rate at which the price increases as the weight increases, so the slope is 0.25.

m = slope, b = y-intercept

C(p) = mp + b

C(p) = 0.25p + 5

Find the simple interest and the total amount after two years.
Principal = 2500=2500equals, 2500 rupees

Total interest ==equals

Total amount ==equals

Answers

Answer:

450

2,950

thats the answer

450 is the total interest amount and 2950 is the total amount.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

To find the simple interest, we can use the formula:

A = P(1 + rt)

Now we can simply substitute the values given in the formula.

Before anything, it is a good practice to define the values of each variable.

P = 2,500

r = 9% or 0.09

t = 2

0.09×2500=225

225 is the interest for one year

450 is the total interest for two years.

Now we proceed to use the values in the formula to find total amount.

A=P(1+rt)

A = 2,500(1 + (0.09 × 2))

A = 2,500(1 + 0.18)

A = 2,500( 1.18 )

A = 2,950.00 Rupees

Hence, 450 is the total interest amount and 2950 is the total amount.

Kristina needs to mix a 20% alcohol solution with a 60% alcohol solution to create 200 milliliters of a 34% solution. How many milliliters of each solution must Kristina use?

Answers

Answer:

20% alc: 135 mL

60% alc: 65 mL

Explanation:

Table:

20% alc / x / (.2)(x)

60% alc / 200-x / .6(200-x)

34% alc. / 200 / (.34)(200)

Equation for 60% alc: .6(200-x) = (.34)(200) + (.2)(x)

Equation for 20% alc: (.2)(x) + .6(200-x) = (.34)(200)

Final:
