Answer:
see below explanation
Step-by-step explanation:
1. 9 (x - 11) = 9
9x - (9 * 11) = 9
9x - 99 = 9
x = 12
2. 4 (3x - 2) = 52
(4 * 3x) - (4 * 2) = 52
12x - 8 = 52
x = 5
3. 44 = 2 (3x - 5)
44 = (2 * 3x) - (2 * 5)
44 = 6x - 10
x = 9
4. 2x- 4/5 = 4
2x - 2²/5 = 4
5(2x) + (-2²) / 5 = 4
x = 12 / 5
5. 3x + 2/2 = 13
3x + 1 = 13
(3x + 1) + (-1) = 13 + (-1)
x = 4
6. 4x -5/5 = 3
4x - 1 = 3
(4x - 1) + 1 = 3 + 1
x = 1
7. 10x + 4/7 = 8
10x + 2²/7 = 8
7(10x) + 2² / 7 = 8
x = 26 / 35
8. 6x - 1/2 = 1
2(6x) + (-1) / 2 = 1
((2 * 6x) - 1 ) / 2 = 1
x = 1/4
What is the y-intercept of the polynomial f(x)f(x) f(x) defined below? Write the y-value only. f(x)=−4x2+x5+10x3+5x+8x4f(x)=-4x^2+x^5+10x^3+5x+8x^4 f(x)=−4x 2 +x 5 +10x 3 +5x+8x 4
Answer:
y = 0
Step-by-step explanation:
Given
f(x) = 4x² +x⁵ +10x³ +5x+8x⁴
Required
Determine the y intercept
The y intercept of a function is a point where x = 0
So, we have to substitute 0 for x in the above function
f(x) = 4x² +x⁵ +10x³ +5x+8x⁴ becomes
f(0) = 4(0)² +(0)⁵ +10(0)³ +5(0)+8(0)⁴
f(0) = 4 * 0 + 0 + 10 * 0 + 5 * 0 + 8 * 0
f(0) = 0 + 0 + 0 + 0 + 0
f(0) = 0
Substitute y for f(0)
y = 0
Hence, the y intercept is 0

Answer:
(i) F = 25 N
(ii) F = 35.36 N
(iii) F = 43.3 N
Step-by-step explanation:
We note that the component of force acting along the incline surface is given by the relation
Force, acting parallel to the incline plane, [tex]F_p[/tex] = M×g×sin(θ)
Given that the weight of the body is given as 50 N, we have;
M×g = 50 N
Therefore we have;
(i) For the plane with angle of elevation = 30°
[tex]F_p[/tex] = M×g×sin(θ) = 50 × sin(30°) = 25 N
The force [tex]F_p[/tex] = F = 25 N
F = 25 N
(ii) For the plane with angle of elevation = 45°
[tex]F_p[/tex] = M×g×sin(θ) = 50 × sin(45°) = 50 × (√2)/2 = 25·√2 N
[tex]F_p[/tex] = F = 25×√2 N = 35.36 N
F = 35.36 N
(iii) For the plane with angle of elevation = 60°
[tex]F_p[/tex] = M×g×sin(θ) = 50 × sin(60°) = 50 × (√3)/2 = 25·√3 N
[tex]F_p[/tex] = F = 25×√3 N = 43.3 N
F = 43.3 N.

Find the equation of the line with gradient-4,
which cuts the y-axis at 7.
Answer:
y = - 4x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the gradient and c the y- intercept )
Here m = - 4 and c = 7, thus
y = - 4x + 7 ← equation of line
Explain why you cannot find the intersection points of the two lines shown below. Give both an algebraic reason and a graphical reason. y=4x+1 and y= 4x+10
Answer:
[tex]m_1 = m_2 = 4[/tex]
Step-by-step explanation:
Given
[tex]y = 4x + 1[/tex]
[tex]y = 4x + 10[/tex]
Required
Show that these two lines have no point of intersection
The general equation of a line is
[tex]y = mx + b[/tex]
Where m represents slope
In [tex]y = 4x + 1[/tex]
[tex]m = 4[/tex]
Similarly; in [tex]y = 4x + 10[/tex]
[tex]m = 4[/tex]
Since the slope of both lines are equal;
[tex]m_1 = m_2 = 4[/tex]
This implies that the lines are parallel and parallel lines have no point of intersection

a carpenter works one third as long after lunch as he worked before lunch if he worked 8 hours total how long did he work before lunch
Answer:
6 hours before lunch
Step-by-step explanation:
Let x = hours before lunch
after lunch = 1/3x
Total time worked = 8 hours
x+1/3 x = 8
Combine like terms
4/3x = 8
Multiply each side by 3/4
3/4 * 4/3x = 8 * 3/4
x = 6
6 hours before lunch
Answer:
The carpenter worked 3x, or 6 hrs, before lunch.
Step-by-step explanation:
Represent the time worked before lunch as 3x and the time worked after lunch as x. Then 3x + x = 8 hrs, and so:
4x = 8 hrs, and
x = 2 hrs
The carpenter worked 3x, or 6 hrs, before lunch.

Answer:
B. x = 7/2 or x=-1/3
Step-by-step explanation:
You know both angles 6x² and 19x+7 have to be the same, so you can solve
6x² = 19x+7
6x² - 19x - 7 = 0
apply the quadratic formula and find
x = -1/3 or x = 7/2
now think carefully if the negative x is a realistic solution. It would lead to the angles being (2/3)°. This is not what the picture suggests, but it is also not wrong, so answer B seems the best.

289 and y more is 206
Answer:
Equation translates to 289 + y = 206
it solves to y = -83
====================================================
Explanation:
The "and y more" means we are adding y onto 289 to get the expression 289+y. This is set equal to 206 because of the term "is" in the original statement.
Therefore, "289 and y more is 206" translates fully to the equation 289+y = 206
This is the same as saying y+289 = 206
To isolate y, we undo what is happening to it. We are adding 289 to it, so we must subtract 289 from both sides
y+289 = 206
y+289-289 = 206-289
y = -83
So we are adding -83 to 289 to get 206

Imagine that you stop at a nearby coffee chain and purchase a $5 coffee every morning on your way to work. You do this 5 days a week for 50 weeks out of the year. While it may seem like a small expense each day, this habit can add up and affect your personal finances. How much would this habit cost you over the next five years
Answer:
$6250
Step-by-step explanation:
Hello!
First, we find out how much you spend a week.
Since you buy a $5 coffee 5 days a week we multiply the price for a coffee by 5.
5 * 5 = 25.
Next, we find out how much you spend a year.
Since you do it 50 weeks a year we multiply the amount you spend a week by 50
25 * 50 = 1250
Then, we find out how much you spend in 5 years.
We multiply the cost a year by the amount of years
1250 * 5 = 6250
The answer is $6250

==============================================
Explanation:
The chords intersect to form the angle 73 degrees. The chords also form the arcs of 96 and x. Averaging the arc measures will result in the internal angle 73
---------
(x+96)/2 = 73
x+96 = 2*73 ... multiply both sides by 2
x+96 = 146
x = 146-96 ... subtract 96 from both sides
x = 50
Given xy = 4 and x2 + y2 = a, which expression is equal to (x + y)2?
a + 6
a + 8
a + 4
Answer:
a + 8
Step-by-step explanation:
Note that
(x + y)² = x² + 2xy + y²
= x² + y² + 2xy
= a + 2(4) = a + 8
Here, we are required to determine an expression equal to (x + y)²
The correct answer is therefore (a + 8)
First, x² + y² = a can be rewritten completing the square method as;
(x+y) (x+y) = a + 2xy
when we expand the expression above; we have;
x² + 2xy + y² = a + 2xy
since, 2xy is present on both sides of the equation;
we still get the expression; x² + y² = a
Therefore, (x+y)² = a + 2xy
we can then substitute the value 4 for xy in the equation above;
Thus, since xy = 4, therefore 2xy = 8
Consequently, (x+y)² = a + 8
The correct answer is therefore (a + 8)

What is the equation of the quadratic function represented by this graph
Answer:
f(x) = - x² + 2x + 8or f(x) = - (x - 1)² + 9 or f(x) = - (x + 2)(x - 4)Step-by-step explanation:
f(0) = 8 {y-axis intercept = (0, 8)}
Vertex = (1, 9)
f(x) = a(x - 1)² + 9
8 = a(0-1)² + 9
8 = a + 9
a = -1
f(x) = - (x - 1)² + 9
f(x) = - (x² - 2x + 1) + 9
f(x) = - x² + 2x - 1 + 9
f(x) = - x² + 2x + 8
x₁ = -2 and x₂ = 4, so also:
f(x) = -(x + 2)(x - 4)
Answer:
g(x) = -1 (x + 2)(x − 4)
Step-by-step explanation:
To write the equation of the function in factored form, g(x) = a(x − r1)(x − r2), find the values of r1, r2, and a.
The function has x-intercepts of -2 and 4, so (x − (-2)), or (x + 2), and (x − 4) are factors of the equation.
To find a, look at how the value of y changes for 1 unit to the right of the vertex. The y-value goes down 1 unit for a point 1 unit to the right of the vertex, so a = -1.
The equation of this quadratic function is g(x) = -(x + 2)(x − 4).
