Answer:
y = 3x - 10
Step-by-step explanation:
Step 1: Rewrite 1st equation
2y = 6x + 4
y = 3x + 4
Step 2: Find 2nd equation
y = 3x + b
-4 = 3(2) + b
-4 = 6 + b
b = -10
Step 3: Rewrite 2nd equation
y = 3x - 10
And we have your parallel equation!
Answer:
-9
Step-by-step explanation:
you're taking away 7 each time, so -2-7=-9
Answer:
20/29
Step-by-step explanation:
sin θ = 21/29
Use Pythagorean identity:
sin² θ + cos² θ = 1
(21/29)² + cos² θ = 1
441/841 + cos² θ = 1
cos² θ = 400/841
cos θ = ±20/29
Since 0° < θ < 90°, cos θ > 0. So cos θ = 20/29.
Answer:
$105.04
Step-by-step explanation:
First add $56 plus 45$ and you will get $101, then times $101 and 1.04 together.
Your answer should be $105.04.
3x-12+5-x=2x-7
2x-7 =2x-7
Means there are infinite solutions.
