Answer:
x = 1 because when you multiply negative 2 by negative six you get twelve. when you multiply positive one by negative six you get negative six.
If it's an equation, such as y=mx+b, the slope is whatever the value of m is. For example, if the equation was y=2x-4, than the slope would be 2.
When solving this on a graph, choose any 2 whole number points. (preferably close together, because it makes it easier) Count how many lines up/down (the y axis) and how many lines over left/right (the x axis) and put the up/down on the top of a fraction and the left/right on the bottom. for example if up was 2, and right was 3, than it would be 2/3. Down is negative, and to the left is also negative. If there are 2 negatives (one on the top and one on the bottom) than they cancel each other out and become positive. For example: -2/-3 would be the same as 2/3. Hope this helps :)
Answer:
$2520
Step-by-step explanation:
18 times 20 = 360
360 time 7 = 2520
Answer:
1. y = 30x
2. y = x+5
3. y = 2x
4. y = x+2
Step-by-step explanation:
1. The speed of a car is x miles per hour. The total distance the car covers is 30 minutes is y
Total Distance = y
Time = 30 minutes
Speed = x
So, equation will be y =30x
2. Tina's age y is 5 years more than her brother Tim's age x.
Tim's age = x
Tina's age y= x+5
So, y = x+5
3. The cost to produce a table y is two times the cost to produce a chair,x
Cost of chair = x
Cost of table = y = 2x
So, y = 2x
4. The time required to bake a chocolate muffin, y is 2 minutes more than the time required to bake a vanilla muffin x
Time to bake vanilla muffin = x
Time to bake chocolate muffin= y= x+2
so, y = x+2
