Answer:
B
-3
Step-by-step explanation:
B is correct but based on the fact that you selected it I'll assume you know why (comment if you want me to explain it)
Then for two lines to be paralell it means that their lines never intersect
The only way for this to be possible is if the lines have the same slope.
This means that the answer is -3
Answer:
let us consider the full weight to be x.
Step-by-step explanation:
1.25% of x = 5
1.25/100 * x = 5
x = 5*100/1.25
x=5*100*100/125
x=100*100/25
x=4*100
x=400
.: full weight would be 400grams.
The answer is B because the domain is the x value, and because the lines have arrows they continue forever, meaning that they contain all real numbers.
Here we want to find the proportional relationship between the number of hours that Abdul charges the suit and the number of hours that he can fly.
We will get the proportional relationship:
y = 2*x
where y is the number of hours that Abdul can fly and x is the number of hours that he charges the suit.
<h3>Proportional relationships:</h3>
A proportional relationship is a linear relationship of the form:
y = k*x
Where k is the constant of proportionality.
We can define:
- x = number of hours that he charges the suit,
- y = number of hours that he can fly.
Now we know that if Abdul charges the suit for 1 hour, he can fly for 2 hours, then we have the pair:
Replacing that in the proportional relationship we get:
2 = k*1
Now we can solve this for k:
2 = k*1
2/1 = k = 2
From this, we can conclude that the proportional relationship is:
y = 2*x

Answer:
Step-by-step explanation:
Well you only want the two equations so here they are.
x + y = -7
5*x + y = 1
I should give you the answer.
x = 2
y = -9 I think. These answers were done in my head.
