Find the equation of a line that satisfies the given conditions; x-intercept = 2, and y-intercept = -8
The equation of a line with an x-intercept of 2 and a y-intercept of -8 is y = 4x - 8, which follows from applying the slope-intercept form and calculating the slope based on the intercepts.
To find the equation of a line with an x-intercept of 2 and a y-intercept of -8, we use the slope-intercept form of a line, which is y = mx + b, where m is the slope and b is the y-intercept.
We can determine the slope by recognizing that the line crosses the x-axis at (2,0) and the y-axis at (0,-8).
The slope m is the rise over the run, which in this case is (-8 - 0) / (0 - 2) = 4.
Therefore, the equation of the line is y = 4x - 8.
This equation satisfies the given conditions, as plugging in x = 0 gives the y-intercept of -8 and setting y to 0, and solving for x yields the x-intercept of 2.
The standard form of the equation of a parabola is x = y2 + 10y + 22. What is the vertex form of the equation?
Answer:
The vertex form of the parabola is [tex]x=(y+5)^2-3[/tex]
C is the correct option.
Step-by-step explanation:
The standard form of the parabola is [tex]x=y^2+10y+22[/tex]
We can write this equation in vertex form by using the completing square method.
For the expression [tex]y^2+10y[/tex], the value of b is 10.
Hence, add and subtract [tex](\frac{10}{2})^2=25[/tex] to the right side of the equation.
Thus, the equation becomes
[tex]x=y^2+10y+25-25+22[/tex]
Now, the expression [tex]y^2+10y+25=(y+5)^2[/tex]
Hence, we have
[tex]x=(y+5)^2-25+22[/tex]
We can simplify further as
[tex]x=(y+5)^2-3[/tex]
Hence, the vertex form of the parabola is [tex]x=(y+5)^2-3[/tex]
C is the correct option.

For a car traveling at a speed of 50 miles per hour, the relationship between the distance traveled, d, and the time traveled, t, is described by the function d = 50t. Which statement is true?
Answer:
The distance traveled is based on the time traveled.
Step-by-step explanation:
I did this question.
The inverse of the given function is t(d) = d/50. The time taken to travel 180 miles is 3.6 hours.
What is speed?Speed is measured as distance moved over time. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).
Speed = Distance/ Time.
Here, we have,
It is given that a car travels at a constant speed of 50 miles per hour. A function for distance traveled is also given as d(t)=50t.
It is required to find the inverse of the function by expressing the time travel in terms of distance traveled and also find t(180).
To find the inverse, express time traveled in terms of distance traveled using normal algebraic methods and then substitute 180 for t and explain its results.
Step 1 of 2
The given function is d(t)=50t.
Consider d(t) as d and t as t(d) and rewrite the equation.
The rewritten function is d=50 t(d)
Divide by 50 on both sides of the equation.
d/ 50 =50 t(d)/50
t(d) = d/50
Step 2 of 2
Substitute 180 for $t$ in the simplified expression and interpret the results.
t(d) = 180/50
= 3.6
The time taken to travel 180 miles is 3.6 hours.
Hence, The inverse of the given function is t(d) = d/50. The time taken to travel 180 miles is 3.6 hours.

Which is the graph of f(x)=(x-1)(x+4)
The quadratic function is described by the standard equation [tex]\boxed{ \ f(x) = ax^2 + bx + c \ }.[/tex]
We have the quadratic function [tex]\boxed{ \ f(x) = (x - 1)(x + 4) \ }.[/tex]

The graph of f(x) = (x-1)(x+4) is an upward-opening parabola with roots at x = 1 and x = -4. It should be plotted carefully, labeling and scaling the axes to show maximum and minimum values, and ensuring it passes through the roots with the proper shape.
Explanation:The graph of the function f(x) = (x-1)(x+4) can be determined by finding the roots and the shape of the curve. The roots of the function can be found when f(x) = 0, which occurs at x = 1 and x = -4. Therefore, these are the points at which the graph will intersect the x-axis. Since it's a quadratic function, its graph will be a parabola.
Additionally, because the coefficient of x² is positive, the parabola opens upwards. To graph this function accurately, one needs to plot the roots and then sketch the parabola, ensuring that it intersects these points and opens upwards. The vertex of the parabola can also be found by averaging the roots, which gives us the x-value of the vertex as (-4 + 1)/2 = -1.5, with the corresponding y-value obtained by evaluating f(x) at x = -1.5.
The resulting graph would start above the x-axis for x < -4, pass through the x-axis at x = -4, reach a vertex at x = -1.5, pass through the x-axis again at x = 1, and continue upwards for x > 1.
The graph should be accurately scaled and labeled with the function f(x) and the variable x, and include the maximum and minimum values on the axes based on the calculated points and the behavior of the quadratic function.

Jane sells 8 times as many Volvos as Melissa. If the difference in their sales is 35, how many cars did Jane sell?
Melissa sold 5 Volvos. Given that Jane sold eight times as many Volvos as Melissa, Jane sold 40 Volvos.
Explanation:In order to solve this problem, we can use a simple equation. Let's denote the number of Volvos Melissa sold as 'x'. Since Jane sells 8 times as many Volvos as Melissa, the number of Volvos Jane sold can be denoted as '8x'. We know from the problem that the difference between the number of cars Jane and Melissa sold is 35, so we can write the equation like this: 8x - x = 35.
By simplifying the equation, we get 7x = 35. Therefore, to find the value of 'x', we divide 35 by 7, which gives us 'x' equals to 5.
But 'x' is the number of Volvos Melissa sold. To find out the number of cars Jane sold, we multiply 'x' by 8. Which gives us 5 multiplied by 8 equals to 40 cars.

What is the value of 6x2 – 4x when x = 5?
Final answer:
To calculate 6x^2 – 4x when x = 5, you square 5 to get 25, multiply by 6 to get 150, then subtract 4 times 5 which is 20, resulting in a final value of 130.
Explanation:
To find the value of the expression 6x^2 – 4x when x = 5, you need to substitute 5 for x in the expression and perform the arithmetic. First, calculate the value of 6x^2 by squaring x (which is 5) and multiplying by 6:
6 * 5^2 = 6 * 25 = 150.
Next, calculate the value of 4x when x is 5:
4 * 5 = 20.
Now subtract the result of 4x from the result of 6x^2:
150 - 20 = 130.
So, the value of the expression when x = 5 is 130.
a bowling ball weighs 48 N. With what net force must it be pushed to accelerate it at 3.0 m/s2
Final answer:
The net force required to accelerate a bowling ball weighing 48 N at 3.0 m/s² is 14.7 N, which we round to 15 N using two significant figures.
Explanation:
To find the net force required to accelerate the bowling ball at 3.0 m/s², we can use Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma). First, we need to determine the mass of the bowling ball. Since the weight of the bowling ball is given as 48 N and weight can be calculated by multiplying mass with the acceleration due to gravity (weight = mass × gravity), we can find the mass (m = weight / gravity). Assuming the acceleration due to gravity is 9.8 m/s², the mass of the bowling ball would be approximately 4.9 kg (48 N / 9.8 m/s²). Next, we apply Newton's second law to find the net force required for the 3.0 m/s² acceleration by multiplying the mass by the desired acceleration (F = ma).
The calculation is as follows:
F = ma = 4.9 kg × 3.0 m/s² = 14.7 N
Therefore, a net force of 14.7 N must be applied to the bowling ball to achieve the acceleration of 3.0 m/s². We typically round this to two significant figures, giving a final answer of 15 N.

In the equation 6x – 2 = –4x + 2, Spencer claims that the first step is to add 4x to both sides. Jeremiah claims that the first step is to subtract 6x from both sides. Who is correct? Explain
Sample Response: Both are correct. As long as inverse operations and the properties of equality are used properly, both methods will generate the same solution. They both isolate the variable on one side of the equation.
Answer:
Spencer and Jeremiah both are correct
Step-by-step explanation:
We have given an equation 6x-2 = -4x+2
In this case spencer and jeremiah both are correct whether we first subtract 6x from both sides or we add 4x to both sides will not lead to any incorrection we will get the same result after simplification from both the methods
If we subtract 6x from both sides we will get 6x-6x-2= -4x-6x+2 after simplification we will get -2 = -10x+2
After further simplification we will get x=4/10=2/5
And if we add 4x on both sides we will get 6x+4x-2= -4x+4x+2 after simplification we will get 10x -2 =2 which eventually gives the result
x=4/10=2/5
Therefore, Both are correct
