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:
Step-by-step explanation:
<u>Negative four is at least six less than a number</u>
<u>Sum of a negative two & nine times a number is less than seventy nine</u>
- -2 + 9x < 79 ⇒ 9x < 81 ⇒ x < 9
<u>Combined inequality:</u>

Answer:
5.88%
Step-by-step explanation:
18 - 17 / 17
1/17 = 0.0588
= 5.88%
Answer:
associative property
Step-by-step explanation:
Grouping like this
a + (b + c) = (a + b) + c
or
a(bc) = (ab)c
is the associative property
