Answer:
D
Step-by-step explanation:
A:
25d - 58 = 234
Add 58 to 58 and 234
25d = 292
Divide 25 from both sides
d = 11
A is incorrect because you need to subtract the pages that have been read.
—
B:
25d + 58d = 234
Combine Like Terms
83d = 234
Divide 83 from both sides
d = 83
B is incorrect because 58 pages aren't days, those are the pages read so this equation is overall incorrect.
—
C:
25 + 58d = 234
Subtract 25 from both sides
58d = 209
Divide both sides by 58
d = 3.603 and so on
C is incorrect because, again, 58 isn't the days its the pages read.
—
D:
25d + 58 = 234
Subtract 58 from 58 and 234
25d = 176
Divide 25 from both sides
d = 7.04
D is the correct answer because 25 is the days and 58 is the pages read. You subtracted 58 from each side, making the number of pages in the book go down because you read those pages. You also divided 176 (the pages left) by the days, so 7.04 is your answer. 7 is the answer rounded down. D is your answer.

Help me out the meaning
slope intercept form:
y = mx + b
m = slope
b = y-intercept
the y-intercept is the place on the y-axis (vertical) where the line crosses. In this problem, the line crosses at (0,4), meaning the y-intercept is 4.
y = mx + 4
the slope is technically the rate of change (rise over run) bewteen points.
If you take the distance from point (-1,3) and (0,4) you get a slope of 1/1, or just 1
y = 1x +4
this could also be:
y = x + 4
(because the 1 is invisible but still there)
Consider the function and the value of a.
f(x) = 5 - x - x^2, a = 0
(a) Use Mtan = lim h->0 [f(a + h) – f(a)] / h
to find the slope of the tangent line mtan = f'(a).
Answer:
Mtan=1-2a
Step-by-step explanation:
Mtan=lim h->0[5-(a+h)-(a+h)^2-(5-a-a^2)/h
=lim h->0[5-a-h-a^2-2ah-h^2-5+a+a^2]/h
=lim h->0[h-2ah-h^2+5-5-a+a-a^2+a^2]/h
=lim h->[h-2ah-h^2 +0+0+0]/h
=lim h->o[h(1-2a-h)/h
=lim h->0 (1-2a-h)
=1-2a-0
=1-2a
Mtan=1-2a.

4. How long does it take a horse to run 300m if its
speed is 15m/s
if f(x)=logx, explain the transformation that occurs when f(0.25(x-5))+3
Answer:
First, let's explain the transformations in a general way:
Vertical shift.
If we have a function f(x), a vertical shift of N units is written as:
g(x) = f(x) + N
This will move the graph of f(x) up or down a distance of N units.
if N is positive, then the shift is upwards
if N is negative, then the shift is downwards.
Horizontal shift.
If we have a function f(x), a horizontal shift of N units is written as:
g(x) = f(x + N)
This will move the graph of f(x) to the right or left a distance of N units.
if N is positive, then the shift is to the left
if N is negative, then the shift is to the right.
Horizontal dilation/contraction.
For a function f(x), an horizontal contraction dilation is written as:
g(x) = f(k*x)
where:
k is called the "scale factor"
If k < 1, then the graph "dilates" horizontally.
if k > 1, then the graph "contracts" horizontally.
Now, in this problem we have:
f(x) = log(x)
And the transformed function is:
g(x) = f(0.25*(x - 5)) + 3
Then, the transformations that take place here are, in order:
Vertical shift of 3 units up:
g(x) = f(x) + 3.
Horizontal shift of 5 units to the right:
g(x) = f(x - 5) + 3
Horizontal dilation of scale factor 0.25
g(x) = f( 0.25*(x - 5)) + 3
replacing f(x) by log(x) we have
g(x) = log(0.25*(x - 5)) + 3.

A 2.5-kg bag of flour contains enough flour to make 4 cakes. a) How much flour is needed to make 50 cakes?
Answer:
31.25 kg of flour is needed to make 50 cakes
Step-by-step explanation:
A 2.5-kg bag of flour contains enough flour to make 4 cakes. a) How much flour is needed to make 50 cakes?
We can find it by using unitary method i.e first find quantity of flour needed for 1 cake and then we can find quantity of flour needed for 50 cakes.
Flour needed to make 4 cakes = 2.5 kg
Flour needed to make 1 cake = [tex]\frac{2.5}{4}[/tex] kg
Flour needed to make 50 cakes = [tex]\frac{2.5}{4}\times 50[/tex]
= 31.25 kg
So, 31.25 kg of flour is needed to make 50 cakes

1. x+y= 7
7x + ty = 77
The system above has NO SOLUTION when t= ?
2. x+y=7
7x+ty=49
The system above has INFINITELY MANY SOLUTIONS when t= ?
t is 35 for x+y= 7 and 7x + ty = 77, and the value of t is 7 for x+y=7 and 7x+ty=49
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given equations are x+y= 7..(1)
7x + ty =77
We need to find value of t.
Multiply equation 1 with 7
7x+7y-7x-ty=49-77
y(7-t)=-28
7-t=-28
-t=-28-7
-t=-35
t=35
Hence the value of t is 35
Now for equations x+y=7
7x+ty=49
7x+7y-7x-ty=49-49
7y-ty=0
y(7-t)=0
7-t=0
t=7
Hence the value of t is 7
Therefore, t is 35 for x+y= 7 and 7x + ty = 77, and the value of t is 7 for x+y=7 and 7x+ty=49

Deanna knows that the floor in her kitchen is a square with an area of 169 ft2. The perimeter of her kitchen floor is found by adding the lengths of all its sides. What is the perimeter of her kitchen floor? Explain how you found your answer.
Answer:
52 ft
Step-by-step explanation:
area of a square is l x w. all sides are equal so the l = w
A = 169 ft^2 so each side is the square root of 169 which is 13 ft
perimeter of the floor would be all four sides added or length of 1 side multiplied by 4 since they are all equal
Perimeter = 13ft × 4 = 52 ft
so:
Answer:
52m
Step-by-step explanation:
Area of the square floor = 169 m²
For a square with each side 's' , area will be s². Similarly , for a square with area 'a' , length of each side will be √a.So,
Length of each side of floor = √169 = 13m
For a square with each side 's' , its perimeter will be 4s.Hence ,
Perimeter of the kitchen = 13 × 4 = 52m
