Answer:
24
Step-by-step explanation:
60 is double of 30 so double 12 to get your answer, 12 time two is 24
All we have to do is get y alone and input our values to see if it makes the statement true.
y - 1 = 3(x + 2)
Add 1 to both sides.
y = 3x + 7
y = 3(1) + 7
y = 3 + 7
y = 10
FALSE
y - 2 = 3(x + 1)
Add 2 to both sides.
y = 3x + 3
y = 3(1) + 3
y = 3 + 3
y = 6
FALSE
y + 1 = 3(x - 2)
Subtract 1 from both sides.
y = 3x - 7
y = 3(1) - 7
y = 3 - 7
y = -4
FALSE
y + 2 = 3(x - 1)
Subtract 2 from both sides.
y = 3x -5
y = 3(1) - 5
y = 3 - 5
y = -2
TRUE
The only equation that makes this statement true is D, y + 2 = 3(x - 1).
Answer:
b) 1
Step-by-step explanation:
First, bring the -3 to the right side.
x²+4x + 4
now use b²-4ac.
4²-4(1)(4)
16-16
0
If discriminant < 0 there are 2 imaginary solutions
if discriminant > 0 there are 2 real solutions
if discriminant = 0 there is 1 real solution
The discriminant here is 0 so it has one real solution
Answer:
y = - 2x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x - 1 ← is in slope- intercept form
with slope m = - 2
Parallel lines have equal slopes , then
y = - 2x + c ← is the partial equation
To find c substitute (- 3, 2 ) into the partial equation
2 = 6 + c ⇒ c = 2 - 6 = - 4
y = - 2x - 4 ← equation of parallel line
