answer:
C. 16
explanation:
when x is 0, the y-intercept is 8
coordinates: (0,8) and (4,6)
slope:
equation:
[ where m is slope and b is y-intercept ]
solve for x-intercept:
note: zeros of a function are the values of x when f(x) is equal to 0
Answer:
Let's solve for x.
2x−y=−5
Step 1: Add y to both sides.
2x−y+y=−5+y
2x=y−5
Step 2: Divide both sides by 2.
2x/2=y-5/2
Answer:
x=1/2y+-5/2
Answer:
y = 60
Step-by-step explanation:
Given
22 + 54 = y + 16 , that is
76 = y + 16 ( subtract 16 from both sides )
60 = y
Answer:
centre = (- 3, - 2) , radius = 1
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Given
x² + 6x + y² + 4y + 12 = 0 ( subtract 12 from both sides )
x² + 6x + y² + 4y = - 12
Use the method of completing the square on the x and y terms
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(3)x + 9 + y² + 2(2)y + 4 = - 12 + 9 + 4
(x + 3)² + (y + 2)² = 1 ← in standard form
with centre = (- (- 3), - (- 2)) and r² = 1, that is
centre = (- 3, - 2) and radius = 1
Answer:
14/5
Step-by-step explanation:
I'd suggest rewriting both mixed numbers as improper fractions. Then we'd have:
14/3 and 5/3
Dividing 14/3 by 5/3 is equivalent to dividing 14 by 5, since the denominators are the same (3).
Quotient is 14/5.
