Answer:
3
Step-by-step explanation:
f(x) = 2x-5
substitute 4 in for x
f(4) = 2*4 -5
f(4) = 8-5
f(4) =3
840 : 360
(÷120) : ( ÷120)
7 : 3

Answer:
THEY ARE 37 AND 28
Step-by-step explanation:
LET THE NUMBERS BE X AND Y
X = 9 + Y
X - Y = 9 ........1
X + Y = 65 .....2
ADDING 1 AND 2
2X = 74
DIVIDING BY 2
2X/2 = 74/2
X = 37
AND X = 9 + Y
: Y = X - 9
PUTTING X = 37
Y = 37 - 9
Y = 28
Answer:
(x - 2)² + (y - 6)² = 49
Step-by-step explanation:
Equation of a circle formula: (x - a)² + (y - b)² = r²
where (a, b) is the center of the circle and r is the radius
Given, center = (2, 6) and radius = 7
Substitute this information in the equation of a circle formula.
⇒ Equation of the circle: (x - 2)² + (y - 6)² = 49
