Write the slope-intercept form of the equation of the line described. through (2, -5) perpendicular to y = 1/3x -1
Answer:
y = -3x + 1
Step-by-step explanation:
Perpendicular lines have opposite reciprocal slopes, so the slope will be -3.
Plug in the slope and given point into y = mx + b
y = mx + b
-5 = -3(2) + b
-5 = -6 + b
1 = b
Then, plug in the slope and y intercept into y = mx + b again:
y = -3x + 1 will be the equation of the line

Aidan has been offered a job to paint the outside of a barn. If one gallon costs $35 and covers 550 square feet. How much will it cost to paint the barn with one coat?
Complete Question
The diagram of the barn is shown on the first uploaded image
Answer:
The cost is [tex]C = \$ 530[/tex]
Step-by-step explanation:
From the question we are told that
The cost of one gallon of paint is [tex]c = \$35[/tex]
The area the one gallon of paint covers is [tex]A = 550 \ square\ feet[/tex]
Generally from the diagram the region of the barn which can be painted is mathematically represented as
[tex]A =80 * 35 + 38 * 35 + 2( \frac{1}{2} * 38 * 2 )[/tex]
=> [tex]A = 8336 \ ft^2[/tex]
From the question
1 gallon covers 500 square feet
x gallon will cover 8336 square feet
So
[tex]x = \frac{8336}{550}[/tex]
=> [tex]x =15 \ gallons[/tex]
Generally the cost of 15 gallons of paint is mathematically represented as
[tex]C = c * x[/tex]
=> [tex]C = 15 * 35[/tex]
=> [tex]C = \$ 530[/tex]

Consider these functions:
For x ≥ 0, the value of f(g(x)) is __
For x ≥ 0, the value of g(f(x)) is __
For x ≥ 0, functions f and g __ inverse functions.
Choices:
1. x,4x,8x
2. x,4x,8x
3. are, are not
Answer:
x
x
are
Step-by-step explanation:
For x ≥ 0, the value of f(g(x)) is x,For x ≥ 0, the value of g(f(x)) will be x and functions f and g are inverse functions.Option a from all the choices is corect.
What is a function?A connection between independent variables and the dependent variable.is defined by the function.
Functions help to represent graphs and equations. A function is represented by two variables one is dependent and another one is an independent function.
The relation between them is shown as y if dependent and x is the independent variable;
Given function;
f(x) = 16x²
g(x)=(1/4)√x
For x ≥ 0, the value of f(g(x)) is found as;
f(x) = 16x²
[tex]\rm f(g(x)) = 16 (\frac{1}{4} \sqrt x) ^2\\\\ f(g(x)) =\frac{16}{16} x\\\\ f(g(x)) = x[/tex]
For x ≥ 0, the value of g(f(x)) is
g(x)=(1/4)√x
[tex]\rm g(x)=\frac{1}{4}\sqrt x \\\\ g(x ) = \frac{1}{4} \times \sqrt{16 \ x^2}\\\\ g(x) = \frac{4}{4} x \\\\ g(x) = x[/tex]
For x ≥ 0, functions f and g are inverse functions
Let,
y=F(X)
If,
y= 16x²
x=16y²
y² = x/16
y=(1/4)√x
Hence,For x ≥ 0, the value of f(g(x)),For x ≥ 0, the value of g(f(x)) will be x and x respectively.and For x ≥ 0, functions f and g are inverse functions.
Hence, option a from all the choices is corect.

The parabola of a given quadratic function opens up. What is true about the vertex of that function?
The vertex is the maximum.
The vertex is unaffected.
There is no vertex.
The vertex is the minimum.
Answer:
D
Step-by-step explanation:
The vertex is a point where the slope is 0 so opening up the vertex is the minimum so option (D) will be correct.
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
The graph is easy to understand behavior of the graph.
For example y = x² form a parabola now by looking at only the graph we can predict that it has only a positive value irrespective of the interval of x.
Vertex is a point where the rate of change or slope of the function is zero.
Since if the slope is zero it means the tangent at that point will be horizontal.
If the parabola opens up then the point where it is changing its direction will be vertex as shown below.
So vertex has a minimum value of y.
Hence "The vertex is a point where the slope is 0 so opening up the vertex is the minimum so option (D) will be correct".

what are the solutions to x^2=16x-28
Answer:
x=14
Step-by-step explanation:
Answer:
x=14
Step-by-step explanation:
Step-1 :
Multiply the coefficient of the first term by the constant 1 • 28 = 28
Step-2 :Find two factors of 28 whose sum equals the coefficient of the middle term, which is -16 .
-28 + -1 = -29
-14 + -2 = -16
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -14 and -2
x2 - 14x - 2x - 28
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-14)
Add up the last 2 terms, pulling out common factors :
2 • (x-14)
Step-5 : Add up the four terms of step 4 :
(x-2) • (x-14)
Answer:
x=14
