Pieter wrote and solved an equation that models the number of hours it takes to dig a well to a level of 72 feet below sea level.
7h – 5(3h – 8) = –72
Which statement is true about Pieter’s solution?
It cannot be a fraction or decimal because the depth of the well is a whole number.
It must be a positive number since it represents a number of hours.
It must be a negative number because the depth is below sea level.
It cannot be greater than –72 because that is the depth of the well.
Answer:
The answer is B or It must be a positive number since it represents a number of hours.

Find the x- and y-intercepts of the equation.
4x − 2y = 2
(A) (1/2,0). (0,1)
(B). (2, 0), (0, −1)
(C). (2, 0), (0, −1)
(D). (1/2, 0), (0, −1)
Answer:
Option D
Step-by-step explanation:
Convert to slope-intercept form:
[tex]4x-2y=2[/tex]
[tex]-2y=2-4x[/tex]
[tex]y=-1+2x[/tex]
[tex]y=2x-1[/tex]
Find the x-intercept by plugging in y=0:
[tex]y=2x-1[/tex]
[tex]0=2x-1[/tex]
[tex]1=2x[/tex]
[tex]\frac{1}{2}=x[/tex]
[tex]x=\frac{1}{2}[/tex]
Therefore, the x-intercept is [tex](\frac{1}{2},0)[/tex]
Find the y-intercept by plugging in x=0:
[tex]y=2x-1[/tex]
[tex]y=2(0)-1[/tex]
[tex]y=0-1[/tex]
[tex]y=-1[/tex]
Therefore, the y-intercept is [tex](0,-1)[/tex]
So, the correct answer is option D.
Answer:
D
Step-by-step explanation:
1. To find the x intercepts, set y equal to 0 and solve for x
4x - 2y = 2
4x -2(0) = 2
4x - 0 = 2
4x = 2
x = 1/2
2. To find the y intercepts, set x equal to 0 and solve for y
4x - 2y = 2
4(0) - 2y = 2
0 - 2y = 2
-2y = 2
y = -1
These are two similar triangles

t2-t1=20-10=10 t3-t2=30-20=10. t4-t3=40-30=10 therefore it is in proportion
The slope and y intercept
Answer:
the y intercept is 5 because the line passes through 5 on the y axis. Now to find the slope, pick two points where the line hits directly on the corner of the grid squares. pIck 2 of those and count the squares up till you are lined up with your other point then count over and get another number. Put the number going up over the number going down like x/y and you'll have your answer. ( simplify it if you can.(-2,3) and (0,5) are a good place to start. The answer should be 2/3.

Solve the system of equations using the substitution method.
x+y=6
x = 2y
Answer:
x=4, y=2
Step-by-step explanation:
if x=2y just put 2y into the spot where x is for x+y=6
x+y=6
(2y) + y = 6
3y = 6
y = 2
now that I know y I can then replace y with the number 2
x= 2y

An electrician leans an extension ladder against the outside wall of a house so that it reaches an electric box 23 feet up. The ladder makes an angle of 75^{\circ}
∘
with the ground. Find the length of the ladder. Round your answer to the nearest hundredth of a foot if necessary.
The length of the ladder that makes an angle of 75 degrees and lies against the wall of a house that's 23 feet tall is approximately 25.88 feet.
The ladder forms a right triangle as it lies against the wall as shown in the image below.
Thus:
x = length of the ladder (hypothenuse)
Reference angle [tex](\theta) = 75^{\circ}[/tex]
25 ft = Opposite
Apply SOH:
Thus,
[tex]sin(\theta) = \frac{Opposite}{Hypotenuse}[/tex]
Plug in the values[tex]sin(75) = \frac{25}{x}\\\\x = \frac{25}{sin(75)} \\\\\mathbf{x = 25.88}[/tex]
Therefore, the length of the ladder that makes an angle of 75 degrees and lies against the wall of a house that's 23 feet tall is approximately 25.88 feet.

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
[tex]-(6y-4)+(6y-4)-(-2)[/tex]
Firstly, let's open the brackets of the 1st term, i.e. - (6y - 4).
[tex] -( 6y - 4) \\ = \underline{\underline{- 6y + 4}}[/tex]
Now, the 2nd term [ (6y - 4) ].
[tex] + ( 6y - 4) \\ = \underline{\underline{ + 6y - 4}}[/tex]
Now, the 3rd term ⇨ - (- 2)
[tex] -( - 2) \\ = \underline{\underline{ + 2}}[/tex]
Now, let's bring the equation together.
[tex]- (6y - 4) + (6y - 4) - ( - 2) \\ = - 6y + 4 + 6y - 4 + 2[/tex]
Now, let's solve the equation.
Firstly, bring the like terms together.
[tex]- 6y + 4 + 6y - 4 + 2 \\ = - 6y + 6y + 4 - 4 + 2[/tex]
Now cancel out -6y & +6y and 4 & -4 as they make 0.
[tex]- 6y + 6y + 4 - 4 + 2 \\ = \bcancel{- 6y }+ \bcancel{6y} + \bcancel{ \: \: 4 } \: \: - \bcancel{ \: 4 }+ 2 \\ = 0 + 2 \\ = 2[/tex]
And, the only number left is 2. So our answer is 2.

Yash can buy three pencils and have 49c change, or he can buy five pencils and
have 15c change.
(1) Write this information as an equation for x the cost in cents of one pencil.
(ii) How much money did Yash have to start with?
Answer:
(ii) 1 dollar
Step-by-step explanation:
each pencil costs 17 cents
- thus 3 pencils x 17c is 51c
1.00 dollars minus 0.51 is 49
- 5 pencils x 17c is equal to 85
1.00 dollars minus 0.85 is 15 c

Solve the simultaneous equations
x-6y=5
xy - 2y2 = 6
-
Show clear algebraic working.
Answer:
(- 7, - 2 ) , (9.5, 0.75 )
Step-by-step explanation:
Given the equations
x - 6y = 5 ( add 6y to both sides )
x = 5 + 6y → (1)
xy - 2y² = 6 → (2)
Substitute x = 5 + 6y into (2)
(5 + 6y)y - 2y² = 6 ← distribute and rearrange left side
5y + 6y² - 2y² = 6
4y² + 5y = 6 ( subtract 6 from both sides )
4y² + 5y - 6 = 0 ← in standard form
(y + 2)(4y - 3) = 0 ← in factored form
Equate each factor to zero and solve for y
y + 2 = 0 ⇒ y = - 2
4y - 3 = 0 ⇒ 4y = 3 ⇒ y = [tex]\frac{3}{4}[/tex] = 0.75
Substitute these values into (1) for corresponding values of x
y = - 2 : x = 5 + 6(- 2) = 5 - 12 = - 7 ⇒ (- 7, - 2 )
y = 0.75 : x = 5 + 6(0.75) = 5 + 4.5 = 9.5 ⇒ (9.5, 0.75 )
(- 7, - 2 ) and (9.5, 0.75 ) are the solutions.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Here, we have,
Given the equations
x - 6y = 5 ( add 6y to both sides )
x = 5 + 6y → (1)
xy - 2y² = 6 → (2)
Substitute x = 5 + 6y into (2)
(5 + 6y)y - 2y² = 6 ← distribute and rearrange left side
5y + 6y² - 2y² = 6
4y² + 5y = 6 ( subtract 6 from both sides )
4y² + 5y - 6 = 0 ← in standard form
(y + 2)(4y - 3) = 0 ← in factored form
Equate each factor to zero and solve for y
y + 2 = 0 ⇒ y = - 2
4y - 3 = 0 ⇒ 4y = 3 ⇒ y = = 0.75
Substitute these values into (1) for corresponding values of x
y = - 2 : x = 5 + 6(- 2) = 5 - 12 = - 7 ⇒ (- 7, - 2 )
y = 0.75 : x = 5 + 6(0.75) = 5 + 4.5 = 9.5 ⇒ (9.5, 0.75 )

The width of a rectangle measures (26 – 8c) centimeters, and its length measures
(106 + 6c) centimeters. Which expression represents the perimeter, in centimeters,
of the rectangle?
Answer:
first one is correct
Step-by-step explanation:
length of a rectangle = 2b - 8c
breadth of a rectangle = 10b + 6c
now , formula to calculate the perimeter of rectangle is
p = 2 (l + w)
no substitute the value of l(length) and w(width)
p = 2{(2b - 8c) + (10b + 6c)}
p = 2(2b - 8c + 10b + 6c)
p = 2(12b - 2c)
p = 24b - 4c

nadia typically types 32 words per minute, but her rate may vary by as much as 5 words per minute. let x be the actual rate at which nadia types. what is the range of rates, in words per minute , that nadia could type
The range of rate at which Nadia could type is given by the inequality equation 27 ≤ x ≤ 37 where x is the number of words per minute
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the total number of words typed per minute be = x
Now , the value of x is calculated by
The number of words Nadia can type = 32 words
The rate of change of words per minute = 5 words
So , Nadia can type 5 words slower or faster
So , the value of x ranges from ( 32 - 5 ) and ( 32 + 5 )
So , the value of x ranges from 27 words per minute to 37 words per minute
The inequality equation is given by
27 ≤ x ≤ 37 , where x is the number of words typed by Nadia per minute
Therefore , the inequality equation is 27 ≤ x ≤ 37
Hence , the range of the inequality equation is 27 ≤ x ≤ 37
