The solution to the systems if equation y = 4x - 5, y = 2x + 3 is (x, y) = (4, 11)
<h3>Equation</h3>
y = 4x - 5
y = 2x + 3
4x - 5 = 2x + 3
4x - 2x = 3 + 5
2x = 8
x = 8/2
x = 4
y = 4x - 5
= 4(4) - 5
= 16 - 5
y = 11
Therefore, the solution to the system of be equation is x = 4 and y = 11

Answer:
13
Step-by-step explanation:
Y = 25 - 3x
X = 4
Y = 25 - 3(4)
Y = 25 - 12
Y = 13

The answer is below
Step-by-step explanation:
1. COST Mr. Rivera wants to purchase a riding lawn mower, which is on sale for 15% off the marked price. The store charges sales tax 6.5% on all sales. Write a function p(x) that represents the price after a 15% discount. Write a function t(x) that represents the total cost with sales tax. Write a composition of functions that represents the total cost of a riding lawn mower on sale. How much will Mr. Rivera pay for a riding lawn mower that has a marked price of $3000?
Solution:
a) Let x represent the marked price and p(x) represent the price after discount. Since a discount of 15% is given, the price would be:
p(x) =
b) If x = discounted price and t(x) = total cost with sales tax, then:
t(x) =
c) Let t(x) represents the total cost with sales tax
Answer:
c = 7p
Step-by-step explanation:
If 1 person buys the platter, the bill is c = 1 × $7.
If 2 people buy the platter, the bill is c = 2 × $7.
If 3 people buy the platter, the bill is c = 3 × $7.
(Do you see the pattern yet?)
If "p" people buy the platter, the bill is c = p × $7.
We ususally say "c is in dollars" and drop the "$" sign from the equation. When p is multiplied by 7, we conventionally write it as 7p.
... c = 7p
