A line intersects the point (3,-4)and has a slope of 17 .what is the slope - intercept equation for this line?
Answer:
The slope - intercept equation for this line is y = 17x - 55
Step-by-step explanation:
The general form of the slope-intercept form is
y = mx +b
where m is the slope and b is the y-intercept.
We are given slope m = 17
we need to find b the y-intercept.
To find y-intercept we would use point(3,-4) and formula
y = -4
x = 3
m = 17
b=?
y = mx + b
-4 = (17)(3) + b
-4 = 51 + b
b = -4 -51
b = -55
So, y-intercept is -55
The slope - intercept equation for this line is y = 17x - 55
Two roots of a 3-degree polynomial equation are 5 and -5. Which of the following cannot be the third root of the equation?
5
5i
0
-5
-5i
Answer:
5i, -5i
Step-by-step explanation:
None 5i nor -5i could be a third root of the polynomial because if we had a complex root then by the complex conjugate root theorem, their conjugate would be a fourth root, while the polynomial which is a 3-degree polynomial can only have three roots according to the Fundamental Theorem of Algebra, which states that the number of roots of the polynomial is equal to the degree of the polynomial.
In other words, for example, if the third root was 5i then its conjugate -5i should be another root according to the complex conjugate root theorem; so we would end with four roots when we are only allowed -by the Fundamental Theorem of Algebra- to have three roots since it is a 3-degree polynomial. The same reasoning applies for -5i whose conjugate is precisely 5i.
The other numbers are real numbers, so any of them can be a third root. Notice that it does not matter if the third root is again 5 or -5 since the real roots can be repeated (multiplicity greater than 1).
The number of miles driven varies directly as the number of hours driven. After
8
hours,
456
miles were driven.
How long, in hours, does it take to drive
627
miles? Do not include units in your answer.
Answer: 11
Step-by-step explanation:
You can set up a ratio.
8/456 = x/627
Cross multiply and divide
8 • 627 = 5016
5016 / 456 = 11
Final answer:
It takes 11 hours to drive 627 miles when the rate is 57 miles per hour, which is derived from the given information that 456 miles are driven in 8 hours.
Explanation:
To determine the travel time for 627 miles when we know that 456 miles were driven in 8 hours, we can use the concept of direct variation. With direct variation, if two variables vary directly, as one increases, the other also increases by a constant multiplier known as the constant of variation (k). In this case, the distance traveled varies directly with the time spent driving.
First, we need to determine the rate of driving based on the information provided:
Distance (d) = 456 milesTime (t) = 8 hoursRate (r) = d/t = 456 miles / 8 hours = 57 miles/hourNow we can use the rate to calculate the time required to drive 627 miles:
Distance (d) = 627 milesRate (r) = 57 miles/hourTime (t) = d/r = 627 miles / 57 miles/hour = 11 hoursIt would take 11 hours to drive 627 miles at that rate.
The parent function f(x)=x3 and a translation, g(x), are shown on the graph. Which represents g(x), then the translated function?
ANSWER
The correct answer is A
EXPLANATION
The parent function is
[tex]f(x) = {x}^{3} [/tex]
The function g(x) is obtained by shifting the graph of the parent function, 4 units left and 6 units up.
Therefore the transformation is of the form:
[tex]g(x) = f(x + 4) + 6[/tex]
Hence the transformed function has equation:
[tex]g(x) = {(x + 4)}^{3} + 6[/tex]
The correct answer is A
The resulting function g(x) after the translation will be g(x) = (x+4)³ + 6
Translation of functionsTranslation is a way of changing the position of an object on an xy plane. According to the graph shown, the parent function of the graph is f(x) = x^3.
The translates function shows an upward translation by 4 units and horizontal translation to the left by 6 units. The resulting function g(x) after the translation will be g(x) = (x+4)³ + 6

What is the domain for the function f(x) = 2^x-5.
Answer:
X= All real Numbers
Step-by-step explanation:
Answer:
All real numbers
Step-by-step explanation:
The domain is the set of x values that we can plug into the function and it will have a y value.
The domain is the "allowed" x values of a function.
Exponential functions of the form [tex]y=a^x[/tex], where a is a constant have domain of "all real numbers".
The function in this problem is of this form with a "-5" at the end, which shifts the function vertically 5 units down. This doesn't affect x values (or domain)
Hence, the domain is the set of all real numbers.

If two angles are supplementary and one of the angles measures 62°, what is the measure of the other angle?
28°
38°
118°
128°
Answer:
118°
Step-by-step explanation:
Supplementary angles sum to 180°
let x be one of the supplementary angles, then
x + 62 = 180 ( subtract 62 from both sides )
x = 118°
The measure of the supplementary angles are 62° and 118°
What are Supplementary and Complementary Angles?Supplementary angles are two angles that have a sum of 180°.
Complementary angles are two angles that have a sum of 90°.
Given data ,
Let the sum of angles be represented as A
Now , let the first angle be represented as p
And , the value of p = 62°
Let the second angle be represented as q
Now , the value of q = q
For supplementary angles , the sum of the angles is 180°
So , on simplifying , we get
A = p + q = 180°
62° + q = 180°
Subtracting 62° on both sides of the equation , we get
q = 180° - 62°
q = 118°
Hence , the measure of the supplementary angles are 62° and 118° respectively

Find the coordinates of the point where y-4x=1 crosses the y axis
Answer:
(0, 1)
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y - 4x = 1 ( add 4x to both sides )
y = 4x + 1 ← in slope- intercept form
with y- intercept c = 1 ⇒ (0, 1) ← coordinates of y- intercept
The coordinates of the point where y-4x=1 crosses the y axis is (0, 1)
The following information should be considered:
The equation of a line in slope - intercept form is y = mx + c Here m is the slope and c the y- intercept.Now y - 4x = 1.So here we have to add 4x to the both sides. So, y = 4x + 1.Now the coordinates is (0,1)

What is the coefficient of the x-term of the fully simplified expression ?
Which point on the x-axis lies on the line that passes
through point C and is parallel to lino AB?
Answer:
(2,0)
Step-by-step explanation:
For given line AB:
y-intercept = b = -2
slope = m = y₂-y₁/x₂-x₁
= -3/2-(-4) = -3/6 = -1/2
Equation of line AB:
y = (-1/2)x - 2
Finding equation of line that is parallel to line AB and passes through the point C(2,2):
Substituting the slope from line AB into the equation of the line
y = (-1/2)x + b.
Substituting the given point (-2,2) into the x and y values 2 = (-1/2)-2 + b.
Solving for b (the y-intercept) , we get b = 1
Substitute this value for 'b' in the slope intercept form equation y = (-1/2)x + 1.
For x-intercept of the line, we let y = 0
0 = (-1/2)x + 1
x = -1(-2/1)
x = +2
So, the point on the x-axis that lies on the line that passes
through point C and is parallel to line AB is (2,0).
at 6 am, an online company has sold 120 items that day. If the company sells an average of 30 items per hour for the remainder of the day , write an expression to represent the number of items that were sold n after 6 am
The expression to represent the number of items this online company sold n hours after 6am is 120 + 30n. Since the company had already sold 120 items at 6am, and then sells an average of 30 items every hour, the overall quantity of items sold is expressed by this linear formula.
Explanation:This is a problem related to linear functions, as the company's rate of sales is constant throughout the day. We are given the company sold 120 items at 6 am, which is our starting condition or 'y-intercept'. Then, we know the company sells an average of 30 items per hour, our rate or 'slope', for the rest of the day.
Therefore, the expression to represent the number of items sold n hours after 6 am is 120 + 30n. Here, 120 represents the number of items sold by 6 am, 30 is the average rate at which items are sold per hour, and n is the number of hours after 6 am.

Explanation:The question involves a linear equation to find the number of items sold by a company n hours after 6 am. Given that the company has sold 120 items by 6 am, and that it sells an average of 30 items per hour for the rest of the day, we represent this scenario with an expression. This can be expressed as 120 + 30n, where n represents the number of hours passed after 6 am.
This equation is made up of two parts: 120 represents the initial number of items sold by the company by 6 am, and 30n represents the number of items the company sells per hour (30) multiplied by the number of hours passed after 6 am (n). Hence, the total number of items sold after n hours will be the sum of these two values.
