Answer:
equation: y=-2x+2
a=-3
b=-8
Step-by-step explanation:
we need to find the equation of the line containing the point (3,-4) and has the slope (m) of -2
slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept
we can plug what we know into the equation:
y=-2x+b
we need to find b though
since the point will pass through the point (3,-4) we can subsitute it into the equation to find b
-4=-2(3)+b
-4=-6+b
2=b
the y intercept is 2
so the equation is y=-2x+2
the line also contains the points (a,8) and (5,b)
first, let's find a
a is the x value of the point
we know the value of y (8)
substitute y as 8 and solve for x
8=-2x+2
subtract
6=-2x
-3=x=a
so a is -3
now find b
b is the y value of the point
we know the x value (5)
substitute x as 5 and solve for y
y=-2(5)+2
y=-10+2
y=-8=b
so b is -8
hope this helps!
answer
system : 8L+ 4S = 120
L + S = 20
There are 10 small packs and 10 large packs
step by step answer :
to form the two systems, we have to determine the catagories of the 2 equations : one for money and one for the no of packs
after forming the two equations we simply put the numbers in the same order put above on the calculator ( mode 5:1) and the calaculator will answer it in seconds . 10 small packs and 10 large packs.
To check your answer , substitute the letters with their values and if both equations gave you the same value at the end then your answer is correct!
[ (52.65 * 5) + 46.25 - 16.25] * 1/6
[ 263.25 + 46.25 - 16.25] * 1/6
293.25 * 1/6 =
293.25/6 =
48.875
error occurred in step 3....he multiplied by 6 instead of multiplying by 1/6
Answer:
Step-by-step explanation:
9: y=5(x-1)^2-3
standard form: y=5x^2-10x+2
10: y=3(x+3)^2+2
standard form: y=3x^2+18x+29
