O slope: 2; y-intercept: 1

Answer:
(2)
Step-by-step explanation:
slope:-1/2
y-intercept:1 (because the function passes (0,1))
The slope of the linear function is -2 and the y-intercept is 2. Therefore, the correct answer is: slope: -2; y-intercept: 2.
What is linear function?A linear function is a type of function where the rate of change of the dependent variable (y) with respect to the independent variable (x) is constant. In other words, the graph of a linear function is a straight line.
To determine the slope and y-intercept of the linear function graphed, we can use the slope-intercept form of a linear equation, which is:
y = mx + b
Where m is the slope and b is the y-intercept.
Looking at the graph, we can see that the line passes through the y-axis at the point (0, 2), which means that the y-intercept is 2. To find the slope, we can choose any two points on the line and use the formula:
slope = (change in y) / (change in x)
For example, we can choose the points (-1, 0) and (1, -4) which lie on the line. The change in y is -4 - 0 = -4, and the change in x is 1 - (-1) = 2. Therefore, the slope is:
slope = (change in y) / (change in x) = -4 / 2 = -2
Hence, the slope of the linear function is -2 and the y-intercept is 2. Therefore, the correct answer is:
slope: -2; y-intercept: 2
Thus, the answer is slope: -2; y-intercept: 2.

Write the slope-intercept form of the equation of the line described.
Through: (5, 4), parallel to y = x-5
Step-by-step explanation:
Find the slope of the parallel line
When two lines are parallel, they have the same slope.
⇒ if the slope of this line = 1
then the slope of the parallel line (m) = 1
Determine the equation
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line: (5, 4)
⇒ y - 4 = 1 (x - 5)
∴ y - 4 = x - 5
We can also write the equation in the slope-intercept form by making y the subject of the equation and expanding the bracket to simplify:
since y - 4 = x - 5
y = x - 1

A. 4a and 7a
B. 3p^2q and -p^2q
C. 2mn and mn^2
D. -x and 3x
Answer:

Like terms must have exactly the same variables and exactly the same exponents.
In C., you have mn and mn^2. That makes the variable parts not the same, so they are not like terms.

PLEASE HELP QUICK!! the cost of one litre of fuel in May 2015 was $0.88. this was a decrease of 20% on the cost in may 2014. calculate the cost of one litre of fuel in may 2014
Answer:
$1.1
Step-by-step explanation:
[tex] \frac{100}{price \: before \: \: decrease \: (x)} \: = \frac{100 - 20}{0.88} [/tex]
[tex] \frac{100}{x} = \frac{80}{0.88} [/tex]
Cross multiply
80x = 88
X = 88/80
X = 1.1
the cost of one liter of fuel in May 2014 was $1.10.
Let's denote the cost of one liter of fuel in May 2014 as "x" dollars.
According to the information given, the cost of one liter of fuel in May 2015 was a decrease of 20% on the cost in May 2014. This means that the cost in May 2015 was 80% of the cost in May 2014.
Mathematically, we can express this as:
Cost in May 2015 = (100% - 20%) * Cost in May 2014
0.88 = 0.8 * x
Now, let's solve for "x" (the cost in May 2014):
x = 0.88 / 0.8
x = 1.10
So, the cost of one liter of fuel in May 2014 was $1.10.

Answer:
2nd option
Step-by-step explanation:
given a quadratic in standard form
y = ax² + bx + c
• If a > 0 then minimum vertex
• If a < 0 then maximum vertex
Here a = - 1 < 0 then maximum
The maximum value is the value of the y- coordinate of the vertex
The x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
Here a = - 1 and b = 3 , then
x = - [tex]\frac{3}{-2}[/tex] = [tex]\frac{3}{2}[/tex]
Substitute this value into the equation for corresponding y- value
y = - ([tex]\frac{3}{2}[/tex] )² + 3([tex]\frac{3}{2}[/tex] ) - 1 = - [tex]\frac{9}{4}[/tex] + [tex]\frac{9}{2}[/tex] - 1 = - [tex]\frac{9}{4}[/tex] + [tex]\frac{18}{4}[/tex] - [tex]\frac{4}{4}[/tex] = [tex]\frac{5}{4}[/tex]
Then maximum value of [tex]\frac{5}{4}[/tex]

Answer:
C
Step-by-step explanation:
Equations of lines that are perpendicular have gradients that are negative reciprocals of each other. This means that the gradient of one of the lines is negative 1 times the fraction flipped.
With the equations presented in the form y = mx + c, the gradient is m. This means you need to look for the values of m where one is the negative reciprocal of the other.
In C, the first gradient is 6/11. The reciprocal (flipped) is 11/6. Make this negative and you get -11/6, which is the gradient of the second equation, so these lines are perpendicular.
Write the expression as a power and evaluate it. 8*2^7
Answer:
1024
Step-by-step explanation:
The expression can be written as [tex]8 * 2^7[/tex]
What is power?An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.
Example: The standard form of the polynomial 5 + 2x + x² is expressed.
We shall first determine the polynomial's degree before expressing it in standard form.
The degree of the provided polynomial is two. Write the phrase containing the polynomial's degree.
Given:
8*2^7
The above expression can be written as
[tex]=8 * 2^7[/tex]
= 8 x 128
= 1024.
Hence, the expression can be written as [tex]8 * 2^7[/tex]

Answer:
The equation of a line in point-slope form is y-Y1=m(x-X1). ”m” is the slope and (X1,Y1) is a point.
So, the equation in point-slope form is y+5=12(x+4).
