Wouldn't the formula be a×b/2?
The equation of the line is y = -2/3x - 3.
To find this, we first need to turn the intercepts into ordered pairs.
x intercept: (-4.5, 0)
y intercept: (0, -3)
Now we can use these two points and the slope equation to find slope.
m = (y2 - y1)/(x2 - x1)
m = (0 - -3)/(-4.5 - 0)
m = 3/-4.5
m = -2/3
Now that we have the slope, we can use slope intercept form to find the intercept.
y = mx + b
-3 = 2/3(0) + b
-3 = 0 + b
-3 = b
Which allows us to model the equation as y = -2/3x - 3
Answer:
Multiply input by 4.
Step-by-step explanation:
So, all we have to do is find the difference between the input/output.
So for the first one.
4y=1x
Divde both sides:
1y=1/4x
Next we have 16y=4x
Divide both sides:
1y=1/4x
Ok, so we now know that y is 1/4x
Or in otherwords, 4x is 1y.
Remember x is input, and y is output.
So we can think of this as the input times 4 equals the output.
This seems to be the second answer.
Hope this helps!
Well, first you go to make a equation like... 35 x 15/100.Then all u gotta do is find y, which is gonna be 5.25. The shirt will cost $5.25
PEMDAS
parenthesis, exponents, mult/division, add/subtract
parenthesis: 4+0.2= 4.2
exponents: 10^2= 10×10= 100
new equation: 10-5/100×0.4(4.2)
multiply/divide: 10-(1/20)×.4×4.2
10-(0.05)(0.4)(4.2)
10-0.002×4.2
add/subtract: 10-0.0084 = 9.9916
~this feels like a wrong answer~
