I believe it is answer b.
Step-by-step explanation:
You multiply 4x and - 7 by 1/5 which gives you 4/5x and 1 2/5. You add 4/5x and 2/5x as they are like terms and get 1 1/5x. The equation then becomes 1 1/5 - 1 2/5
What is the solution?

Kelly bought a soda for three dollars and 7 candy bars when she went to the movies. She spent a total of $21. How much did each candy bar cost? Write out and solve. Show work
Answer:
$2.57
Step-by-step explanation:
Create an equation.
7x + 3 = 21
Subtract 3 from both sides of the equation.
7x = 18
Divide 7 from both sides to find x.
18/7 = x,
x = 2.57
Each candy bar costs 2.57 dollars,

Martin has 128 pencils that he is putting
into boxes. Each box holds 6 pencils. If he
puts all the pencils into boxes, how many
more pencils will he need to fill the last box
completely?
128 pencils divided by 6 pencils that can be put in a box; 128÷6=21 with a remainder of 3
Martin needs 3 more pencils for the last box, beacuse he has 3 leftovers and 6 can go into the box. 6-3=3

C. Again, assume that we can't produce more than 1,000 un necessarily some x value, let's call it C, for which the profit is exactly 0? Explain your answer. 2. For the following: A. Produce a function f(x) that satisfies the following conditions: 1. Its domain is all real numbers. 11. It has no maximum and no minimum on the interval (1, 3). III. It satisfies f(1) = 1 and f(3) = -1, but there does not exist a c between 1 and 3 such that f(x) = 0. B. Construct a function f(x) that satisfies the following conditions: C. fis continuous for all x.
Answer:
C. Yes, there is an x-value that is exactly zero. This is true because zero is our starting point in our profits. The x and y value would be (0,0) as we have just begun to produce energy units. Once the graph starts to increase, we cannot have a point at exactly zero, unless the profits have a dramatic drop to the x value of 0. This would then be (0, at a number of diminishing returns)

2x+3y=24 in slope intercept form
Answer:
3y = -2x + 24
y = -2/3x + 8
Step-by-step explanation:
Answer:
The slope-intercept form is y=mx+b y = m x + b
Step-by-step explanation:
where m m is the slope and b b is the y-intercept. Subtract 2x 2 x from both sides of the equation. Divide each term by 3 3 and simplify. Divide each term in 3y=24−2x 3 y = 24 - 2 x by 3 3 .

Help a person out asap plz
Answer:
m∠1 = 52, m∠2 = 60
Step-by-step explanation:
68 and ∠2 are interior angles. 128 is exterior angle.
Formula : -
Sum of two interior angles = Exterior angle
68 + ∠2 = 128
∠2 = 128 - 68
∠2 = 60
∠1 and 128 are linear pair angles. Sum of linear pair angles is 180,
∠1 + 128 = 180
∠1 = 180 - 128
∠1 = 52

which of the following quotients is greater that 9 and less than 12.
a) 144/12
b) 250/20
c) 320/20
d) 81/9
please help me
Answer:
(D)
Step-by-step explanation:
Becuase 81 is greater than 9 and 9 is less than 12 (I hope this helps) :)
Step-by-step explanation:
12 less ( subtracting 12 from something else)
the quotient-Dividing between two values
A number: let's use Y
so we want to substract 12 from the product of y/9
(Y/9) -12.
So 81 is greater than 9 but 9 is less than 12.

Susan is choosing tween two cell phone plans that offer the same amount of free minutes.
Plan A charges $29.99 per month with additional minutes costing $0.45
per minute.
Plan B charghes $39.99 a month with addtional minutes costing $0.40 per minute. If the equation for Plan A is
0.45x + 29.99 and the equation for plan E
is 0.40x+ 39.99, then how many addtional minutes, x, will it take for the two plans to cost the same?
Answer:
200
Step-by-step explanation:
You can simply just graph it and see where the points intersect, or you can do it algebraically.
0.45x+29.99=0.40x+39.99 subtract 29.99 both sides
0.45x=0.40x+10.00 subtract .40x both sides
0.05x=10.00 divide both sides by 0.05
x=200

f(x)=2+|x-3| for all x than the value of the derivative of x=3 is
The derivative at x = 3 does not exist.
To see why, recall the definition of absolute value:
[tex]|x| = \begin{cases}x&\text{if }x\ge0\\-x&\text{if }x<0\end{cases}[/tex]
If x - 3 ≥ 0, then
2 + |x - 3| = 2 + (x - 3) = x - 1
and the derivative of this piece is 1 for all x > 3.
If x - 3 < 0, then
2 + |x - 3| = 2 - (x - 3) = 5 - x
and its derivative is -1 for all x < 3.
The derivatives to either side of x = 3 are not the same, so f '(x) is not continuous and indeed does not take on any value at this point.

Line segment XY has endpoints X(5,7) and Y(-3,3)
y=-2x+7
Step-by-step explanation:
line segment xy has endpoints x(5 7) and y(-3 3)
for the equation of the perpendicular bisector of line segment xy
slope of line segment xy = 7-3 / 5+3
= 4/8
=1/2
so slope of perpendicular bisector is -2
as m1m2= -1 or m1= -1/m2
As perpendicular bisector goes through midpoint of xy , let's find midpoint of xy
midpoint(x,y) = (5-3 / 2 , 7+3 / 2)
=(2/2, 10/2)
=(1,5)
find the equation of line(perpendicular bisector) passing through (1,5) and the slope -2
y-5 = -2(x-1)
y-5 =-2x+2
y=-2x+7
