The area of a circle is π r²

So we do:

π x 11.7² = 430

Create an equation from this table.

Lerok [7]

Look like a linear equation. let's try finding the slope:
(7-4)/(1-0)=3
(4-1)/[(0-(-1)]=3
[1-(-2)]/[-1-(-2)]=3
indeed, it is linear, with a slope of 3
when x=0, y=4, so the y intercept is 4
the equation of the line is y=3x+4

Jayden has x nickels and y pennies. He has at most 14 coins worth no less than $0.34 combined. Solve this system of inequalities

oee [108]

Answer:

Step-by-step explanation:

Number of nickels with Jayden = x

Number of pennies with Jayden = y

Since, number of coins is at most 14,

x + y ≤ 14 -------(1)

Worth of nickels = $0.05x

Worth of pennies = $0.01y

Since, worth of pennies is not less than $0.34,

0.05x + 0.01y ≥ 0.34

5x + y ≥ 34 --------(2)

By using a graphing calculator,

Common point of of both the inequalities is (5, 9)

Therefore, Number of nickels = 5

Number of pennies = 9

the sum of two numbers is 50 the first number is 43 less than twice the second number write and solve a system of equations to f

Korolek [52]

A + b = 50
a = 2b - 43
2b - 43 + b = 50
+43 +43
3b = 93
b = 31
(31 x 2) - 43 = 19
a = 19 b = 31
31 + 19 = 50
