Answer:
1/2
Step-by-step explanation:
So lets go over what slope is.
The formula for slope is y/x
To find this, we can just count the change in y, and put it over x.
So lets see.
On the graph, we can count that y goes up by one, and that x goes to the right by 2.
So this means our slope is y/x, or 1/2.
This is our answer.
I hope this helps! :)
I included a visual of this as well!
You can find the dimensions of the model and plug them into the formula for volume (length x width x height)
Answer:
∠B
7(13)-1=90˚
Step-by-step explanation:
Are you saying ∠ABC or ABC as sides?
1. ∠ABC
(7x-1)+(4x+1)+(3x-2)=180˚
14x-2=180˚
14x=182
x=182/14
x=13˚
2. plug in
∠A
4(13)+1=53˚
∠B
7(13)-1=90˚
∠C
3(13)-2=37˚
Answer:
Percent change is comparing one current number or value to another.
Percent difference is comparing a number or value to another number or value.
Step-by-step explanation:
Answer:
You will need to use simultaneous equations.
Method:
Get both equations to have the same subject, in this case we will multiply the first equation by 4
1) 2x-y = -1
Becomes
1) 8x-4y = -4
Then make both equations equal to 4y.
1) 8x+4= 4y
2) 4y = -5x + 17
Because they both equal 4y, that means they are equal to each other.
8x+4 = -5x+17
Now solve for x.
13x = 13
x = 1
Now that we have x, we can substitute it back into either equation to get y. I will use equation 1 because it is less complex.
2x-y = -1
2(1)-y = -1
y = 3
