Answer:
Step 2-3
Step-by-step explanation:
I don't know what's wrong with step 2 but in step 3 the student added the exponent instead of multiplying.
That automatically makes every other step done afterwards wrong but it's not 3-4 because the math is right it's just that step 3 messed up step 4 laws of exponent wise.
On a coordinate plane, 3 lines are shown. Line a has points (negative 3, 3) and (3, negative 3). Line b has points (negative 3, negative 2) and (2, 3). Line c is parallel to line b.
If line b is perpendicular to line a, and line c is perpendicular to line a, what is the slope of line c?
Answer:
slope c =1
Step-by-step explanation:
slope for line (y2-y1)/(x2-x1)
slope of line a = (-3-3)/(3-(-3))
slope of line a = -6/6 = -1
if line c is perpendicular to line a, so relationship for slops are
(slope a) *(slope c)= -1
(-1)*(slope c) = -1
slope c =1

Enzo is driving to his niece's t-ball game. his sister gave him directions. what will
happen if enzo follows these directions?
turn east off 1st avenue at lake drive. drive 3 miles. make a 90° right turn and drive
1 mile. turn 90° at the intersection. you will reach the field in 2 miles.
a
The direction given by Enzo's sister is an illustration of distance
Enzo's distance from the east of 1st avenue to the field is 6 miles
How to describe the directions?From the question, we have the following directions:
Start at east of 1st avenueDrive 3 milesMake a 90 degrees right turnDrive 1 mileTurn at 90 degrees intersectionDrive 2 milesThe above directions imply that the total distance from the east of 1st avenue to the field is:
Distance = 3 miles + 1 mile + 2 miles
Evaluate the sum
Distance = 6 miles
Hence, Enzo's distance from the east of 1st avenue to the field is 6 miles

one sixth of a number is 9 algebraic expression
Answer:
x= 54
Step-by-step explanation:
let the number be (x)
so One sixth of x will be 9
numerically,
1/6 × (x) =9
x= 9×6
x= 54
One-sixth can be written as [tex]^1/_6[/tex]
now, let the number be y
so one-sixth of y is written as
[tex]^1/_6~y~=~9[/tex]
If it's necessary to solve for y, consult the [Solving for y] section of this ans ↓[Solving for y]First we need to get rid of the fraction, one-sixth.
since in mathematics we can't just terminate fractions without altering the equation/expression itself, we need to perform an operation.
the first one is multiplication; we will multiply both sides of the equation by 6 (the denominator of the fraction)
[tex]^1/_6*6~y~=~9~*~6}[/tex]
On the left-hand side the 6's cancel, and we're left with
1 y = 9 * 6
Or
y = 9* 6
Which simplifies to :
y = 54

Step-by-step explanation:
Given
[tex]\frac{x}{a}= \frac{y}{b} =\frac{z}{c}[/tex]
[tex]Let \: \frac{x}{a}= \frac{y}{b} =\frac{z}{c}=m[/tex]
(where m is any constant)
[tex]\implies[/tex]
[tex]\frac{x}{a}=m\implies x =am[/tex]
[tex]\frac{y}{b}=m\implies y =bm[/tex]
[tex]\frac{z}{c}=m\implies z =cm[/tex]
To Prove:
[tex]\frac{ax-by}{(a+b)(x-y)}+\frac{by-cz}{(b+c)(y-z)}=2[/tex]
LHS [tex]=\frac{ax-by}{(a+b)(x-y)}+\frac{by-cz}{(b+c)(y-z)}[/tex]
(Plug the values of x, y and z in the form of am, bm and cm respectively in the LHS)
[tex]=\frac{a(am)-b(bm)}{(a+b)(am-bm)}+\frac{b(bm)-c(cm)}{(b+c)(bm-cm)}[/tex]
[tex]=\frac{a^2m-b^2m}{(a+b)m(a-b)}+\frac{b^2m-c^2m}{(b+c)m(b-c)}[/tex]
[tex]=\frac{m(a^2-b^2)}{m(a+b)(a-b)}+\frac{m(b^2-c^2)}{m(b+c)(b-c)}[/tex]
[tex]=\frac{\cancel{m(a^2-b^2)}}{\cancel{m(a^2-b^2)}}+\frac{\cancel{m(b^2-c^2)}}{\cancel{m(b^2-c^2)}}[/tex]

How many different plates can be made with 2 vowels and a digit?
============================================================
Explanation:
If repeats are allowed, then we have 5 vowels (a,e,i,o,u) for the first vowel slot, and 5 choices for the second vowel slot. We also have 10 choices for the numeric digit (0 through 9).
There are 5*5*10 = 250 ways to make a selection of the form LLN where L stands for "letter" (specifically a vowel) and N stands for "number". An example plate could be AE2.
There are also 250 ways to make a selection of the form LNL and 250 ways to select something of the form NLL.
That means there are 3*250 = 750 ways to make a license plate with two vowels and a digit where repeats are allowed.

Answer: Its not possible.
Step-by-step explanation:There aer two vairables. Whats the value of N
Hey there!
n = 4/5(m + 7)
n = 4/5(1m + 7)
n = 4/5(1m) + 4/5(7)
n = 4/5m + 28/5
n = 4/5m + 5.6
Thus, your answer is probably:
n = 4/5m + 5.6 or n = 4/5m + 28/5

Ο Α. 1536
O B. 43
O C. 133
O D. 47°
Answer:
<3=C. 133
Step-by-step explanation:
Well, angle 2 and angle 3 are corrisponding angles, meaning that they are on the same line, and a line is always equal to 180, and 47 degrees is a part of that line, and you need the other part of that line for angle 3, so you simply subtract 180-47=133 degrees

Shannon mistakenly mixed up angles A and B. Notice the side 9 is opposite angle B and not angle A.
She should replace every copy of uppercase A with uppercase B. Also, she should replace lowercase 'a' with lowercase b
This is what her steps should look like
[tex]\frac{\sin B}{b} = \frac{\sin C}{c}\\\\\frac{\sin B}{9} = \frac{\sin 125^{\circ}}{12}\\\\B= \sin^{-1}\left(\frac{9*\sin 125^{\circ}}{12}\right) \approx 37.9^{\circ}\\\\[/tex]
Then we can find angle A like this
[tex]A+B+C = 180\\\\A = 180 - B - C\\\\A \approx 180 - 37.9 - 125\\\\A \approx 17.1^{\circ}\\\\[/tex]
Angle A is approximately 17.1 degrees.
The rate for shipping by air express is $8.50 per 100 kg.

Answer:
It will cost $21.25
Step-by-step explanation:
We can use ratios to solve
8.50 x
-------- = -----------
100 kg 250 kg
Using cross products
8.50 * 250 = 100 x
Divide each side by 100
8.50 * 250/100 = x
21.25 = x
It will cost $21.25

Step-by-step explanation:
The given equation is in "point-slope" form:
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
Comparing the equation to the form, you see ...
m = 3(h, k) = (-1, -3)__
The equation is easily graphed by plotting the point (-1, -3) and then drawing a line through it that has a slope (rise/run) of 3. That is, the line will go up 3 grid squares for each grid square to the right. (The origin is a point on the line.)

Step-by-step explanation:
The surface area of a prism is the total area of all its faces.
A triangular prism has three rectangular faces and two triangular faces.
As all 3 sides of the triangle face of this prism are equal, each of the 3 rectangular faces are also equal in area.
Formulae
Area of a triangle = 1/2 x base x heightArea of a rectangle = width x lengthFrom inspection of the diagram:
⇒ Area of a triangle = 1/2 x 8 x 7 = 28 in²
⇒ Area of a rectangle = 8 x 10 = 80 in²
Total surface area
Total surface area = 3 rectangle areas + 2 triangle areas
= (3 x 80) + (2 x 28)
= 296 in²
Answer:
296

The number is 17 and less and the inequality is 3x + 11 ≤ 62
Given,
Eleven more than three times a number is at most 62
We need to find the number and the inequality.
What are the inequalities?
< mean less than
> means greater than
≤ means less than or greater than
≥ means greater than or equal to
Find the meaning of the statement.
more than means adding
times means multiply
At most 62 means the maximum is 62 and we use ≤ 62.
Find the expression.
Eleven more than three times a number is at most 62
Let x be the number.
3x + 11 ≤ 62
Find x value.
3x + 11 ≤ 62
3x + 11 62
3x ≤ 62 - 11
3x ≤ 51
x ≤ 51/3
x ≤ 17
Thus the number must be 17 and less and the inequality is 3x + 11 ≤ 62

Answer:
L < 5.25yd
Step-by-step explanation:
We can think of Mrs. Klein's composting area as a rectangle, and the formula for finding the area of a rectangle is Base * Height = Area (B*H=A)
Let's just say for the sake of solving the problem that they say that area of the garden had to be exaclty 6 square feet. Because the area must be 6sqft (sqyd = square yards) then we can enter 6 into our formula.
B*H=A now equals B*H=6
They also tell us that the width (which is a stand-in for height) is [tex]1\frac{1}{7}[/tex] so we can enter that in our formula as well
B*H=6 now is [tex]B*1\frac{1}{7} =6[/tex] and now we just have one unknown... the B (base)
And since [tex]B*1\frac{1}{7} =6[/tex] then [tex]6/1\frac{1}{7} =B[/tex]
Thus,
[tex]6yd / 1\frac{1}{7} = 5.25yd[/tex]
And because the question said that the area must be less then 6sqyd, then the length can be anything less then 5.25yd.
Thus,
L < 2.25

Together, teammates Pedro and Ricky got 2680 base hits last season. Pedro had 280 more hits than Ricky. How many hits did each player have?
Answer:
Ricky it is 1,202
And for Pedro 1202 + 276 = 1478
Step-by-step explanation:
The computation is shown below:
Let us assume the ricky be x,
So, pedro be x + 276
Now the equation is,
x + x + 276 = 2680
2x + 276 = 2680
2x = 2680-276
2x = 2404
x = 1,202
For Ricky it is 1,202
And for Pedro 1202 + 276=1478
