Answer: y=-5/2x+13
Step-by-step explanation:
Since we are given the slope, we can plug it into our equation and use the point given to find the y-intercept.
y=mx+b
y=-5/2x+b
-2=-5/2(6)+b
-2=-15+b
b=13
Now that we know the y-intercept, we can complete the equation.
y=-5/2x+13
Answer:
x= -5 and y= 9
Step-by-step explanation:
In the writing of coordinates, the coordinate is always the first number in the set and the y coordinate is always the second number.
that is (x, y)= (-5 , 9)
Answer:
48.2 in^3
Step-by-step explanation:
It'd be easier to calculate the volume if you'd change the mixed numbers to mixed numers with decimal fractions:
2 1/2 becomes 2.5
3 2/3 becomes 3.67
5 1/4 becomes 5.25
Then V = L*W*H, or
V = (5.25 in)(3.67 in)(2.5 in) = 48.2 in^3
Answer:
5/1 or 1/2
Step-by-step explanation:
got it right on the test. sorry I'm a little late. Have a great day/night
X=15% alloy
y=8% alloy
x+y=40
y=40-x
0.15x+0.08y=40*0.10
0.15x+0.08(40-x)=40*0.1
times 100 both sides for easy
15x+8(40-x)=400
15x+320-8x=400
7x+320=400
minus 320 from both sides
7x=80
divide both sides by 7
x=80/7
x+y=40
80/7+y=280/7
y=200/7
aprox
x=11.4lb
y=28.6lb
11.4lb of 15%
28.6lb of the 8%
what????
