Answer:
D.) 7 and -4
Step-by-step explanation:
Coefficients are numbers placed directly before a variable.
(7) is a coefficient because it is placed before x².
(-4) is a coefficient because it is placed before x. The negative is included.
(6) is not a coefficient because it is not altering any variable through multiplication/division.
The perimeter is adding all the outside edges together:
4 + 1 +4 +1 + 3 + 1 = 14 cm.
The x intercept is the amount of money she has and I don't know what it is.... sorry. I knew what it stood for though.
Can I get your number and I will help you
Answer: It will take Damon 6 weeks to save the money he needs to buy the snowboard
Step-by-step explanation:
First, let's see what the problem is giving us:
-The variable X will represent the number of weeks it will take Damon to save the money he needs.
- Damon has $40
- Damon is going to safe $20 weekly
- The snowboard costs $160
Therefor:
Our equation will be: $40 + $20X = $160
Step 1
We need to isolate the variable by subtracting in both sides of the equation 40 in order to maintain the equality.
40 - 40 + 20X = 160 - 40
This will let us with 20X = 120
Step 2
We have to isolate the variable again, but this time (because the variable is being multiplied by 20) we have to divide on both sides of the equation.
20X/20 = 120/20
Therefore: X=6
