ANSWER
The standard form is:

EXPLANATION
The given line passes through (4,10)and (6,11).
The slope of this line is


The equation is given by the formula,

We plug in the first point and the slope to get.




The standard form is

We are given ratio nickel to zinc to copper = 2:7:9.
From this ratio we can see that <em>ratio of nickel to zinc is 2:7</em>.
Let us assume number of pounds of nickel have to be used to create alloy that contains 4.9 lb of zinc is x pounds.
So, we can setup a proportion as :
x : 4.9 = 2:7
Or

On cross multiplication, we get
7x= 4.9× 2
7x = 9.8
Dividing both sides by 7, we get
x = 1.4.
<h3>Therefore, 1.4 pounds of nickel have to be used to create alloy that contains 4.9 lb of zinc.</h3><h3 />
Answer:
1/5
Step-by-step explanation:
Answer:
58.5
Step-by-step explanation:
0.65 decimal form
then times that by 90
then you got the answer 58.5
I believe your answer should be 105x squared-1475x+70
sorry i'm not really sure how to put the little two above the first x but my answer is mathematically correct.
