Step-by-step explanation:
All of the other surfaces have an incline - imagine that there is a ball at the top, and the change in elevation makes it roll down. A screw does not have an incline, and therefore is not,,, an inclined plane.

Answer:
[tex]x<-6; x\ge2[/tex]
Step-by-step explanation:
We're taking values from -6 and behind, and the dot over -6 is empty, so it's not included. That means [tex]x<-6[/tex]. Moreover, the rest of the line goes from 2, with a solid dot, and ahead. That translates in [tex]x\ge 2[/tex]

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]

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

Answer:
t = 12
Step-by-step explanation:
t*5 = 60
Divide both sides by 5
t = 60/5

Find the equation of the line that passes through the points (-1,8)
and (2, -1). Write your equation in slope-intercept form. Show all
work to support your answer.
Answer:
y = -3 * x + 5
Step-by-step explanation:
We start with the equation for slope-intercept y = mx + b -
Y is any y point on the line. X is any x point on the line. M is the slope of the line. B is the y-intercept of the line.
We first find the slope by using this equation (y2 - y1) / (x2 - x1) -
(8 - (-1)) / ((-1) - 2)
9 / (-3)
Slope = -3
Now we insert the slope into the equation -
y = -3 * x + b
As said before, Y is any y point on the line and X is any x point on the line, so we can choose a random point and insert it in to find the y-intercept -
-1 = -3 * 2 + b
-1 = -6 + b
b = 5
The y-intercept of the line is (0, 5)
We insert the y-intercept in the equation -
y = -3 * x + 5
y = -3 * x + 5 is our answer to the problem.

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.

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.
