What are the coordinates for the x and y intercepts of the function 4y - 2x = 24?

Answers

For 4y, I believe the coordinates are (4,6) and the coordinates for 2x are (2,12). This is my best guess. Let me know if I'm wrong.
First, let's put this in Slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.
4y - 2x = 24          Add 2x to both sides
4y = 2x + 24         Divide both sides by 4
y = (1/2)x + 6
Now that we're in slope-intercept we can easily find the y and x intercepts/
b = 6, so the y-intercept equals 6. Plug zero in for x to confirm!

Now we plug 0 in for y to find the x intercept:
0 = (1/2)x + 6     Subtract 6 from both sides
-6 = (1/2) x          Multiply both sides by 2
-12 = x
The x intercept is -12

In Conlusion:
x-intercept = -12
y- intercept = 6

Hey Johna!

4x - 9 = k
Add 9 to both sides
4x - 9 + 9 = k + 9
4x = k + 9
Divide both sides by 4

What number appears 7 times in the multiplication table?

Answers

Final answer:

In a multiplication table, each number from 1 to 12 would appear 12 times corresponding to each multiplier. In a table specific for a single number, that number would repeat 12 times.

Explanation:

The question is asking about a number that appears 7 times in a multiplication table. In a multiplication table, numbers 1 through 12 are repeated 12 times, once for each multiplier. However, in a multiplication table between 1 and 10, the number 1 appears multiple times as it is a factor for every other number. As an exception, if we have a multiplication table that is specific to a certain number, for example, the number 7, then number 7 would appear 12 times as it is the constant multiplier for each number in the table.

For which value of k will the roots of the equation 2x^2-5x+k=0 be real and rational numbers

Answers

The trick here is to find the discriminant, b^2-4ac, of the equation 2x^2 - 5x + k.
Here a=2, b=-5, and c=k.

So long as the discriminant is 0 or greater than 0, your roots will be real and rational numbers.

Thus, compute b^2-4ac:  (-5)^2 - 4(2)(k)

Let this equal zero and solve for k:  25=8k; k=25/8.

So long as k is 25/8 or smaller, b^2-4ac will be 0 or greater, and the roots will be real and rational.

25/8 is the  value of k will the roots of the equation 2x^2-5x+k=0 be real and rational numbers

What is quadratic equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .

We need to find  the value of k will the roots of the equation 2x²-5x+k=0 be real and rational numbers.

A quadratic equation has real roots when the discriminant is positive or zero (not negative).

b²-4ac≥0

b=-5, a=2, c=k

(-5)²-4((2.k)≥0

25-8k≥0

25≥8k

Divide both sides by 8

25/8≥k

k≤25/8

Hence, 25/8 is the  value of k will the roots of the equation 2x^2-5x+k=0 be real and rational numbers

Eighteen cement squares cover a patio with an area of 40.5m^2. What is the side length of one of the squares

Answers

Final answer:

The side length of each of the cement squares is 1.5m. This is calculated by dividing the total area by the number of squares to find the area of each square, and then taking the square root to find the side length.

Explanation:

To solve this question, we need to first understand that the total area of the patio equals the sum of the areas of each individual cement square. There are eighteen squares, and the total area is 40.5 square meters. This means that the area of one cement square can be acquired by dividing the total area by the quantity of the squares.

So, the calculation would be 40.5m² / 18, giving us an area of 2.25m² for each square.
Now, since these are squares and all sides of a square are equal, their area is represented by the square of one side length. Therefore, to get the length of one side, we extract the square root of the area.

The calculation is √2.25, which equals 1.5. So, the side length of one of the cement squares is 1.5m.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The product of two numbers is 20 and whose sum is 12

Let the numbers are x and y

xy = 20

x + y = 12

y = 12 - x

x(12 - x) = 20

x² - 12x + 20 = 0

After solving the above quadratic equation, we get:

x = 10, 2

y = 2, 10

Thus, the numbers are 10 and 2 if the product is 20 and whose sum is 12 after making the two equations.

Answers

Harry has 9 points. First, make some expressions to show what you know. I'll use the variables b, h, and n to represent the number of points each player has h = b/2 n = h - 5 b + h + n = 31 Substitute h - 5 for n in the 3rd expression b + h + h - 5 = 31 Now substitute b/2 for the h's in that expression b + b/2 + b/2 - 5 = 31 Now solve for b, first add the b terms together 2b - 5 = 31 Add 5 to both sides 2b = 36 Divide both sides by 2 b = 18 We now know that Butch has 18 points, so plug that value into the formula for Harry's points h = b/2 h = 18 / 2 h = 9 And we now know that Harry has 9 points.

At one point on the trip, the miles are recorded as 15,121 when the gas tank is 75% full. Use a ratio equation to determine the miles per gallon the sedan averages. Round your answer to the nearest whole number.

Answers

The most common size of a sedan tank is 18.5 gallons. So if it is 75% full, it contains 13.875 gallons of gas. If it recorded a mileage of 15,121 miles, mileage per gallon, therefore, is 1090 rounded off to the nearest whole number.

Given: Gas full tank of a sedan – 18.5 gallons

            75% full = 13.875 gallons

            Mileage using 13.875 gallons of fuel = 15,121 miles

The mileage per gallon computation using the ratio equation:

Ratio is 15121:13.875 or

            X/1= 15121/13.875

            13.875x = 15121

            X = 15121/13.875

            X =1089.80 or 1090 miles per gallon (rounded off)

Talia wants to write the equation of the graphed line in point-slope form. These are the steps she plans to use: Step 1: Choose a point on the line, such as (2, 5). Step 2: Choose another point on the line, such as (1, 3). Step 3: Count units to determine the slope ratio. The line runs 1 unit to the right and rises 2 units up, so the slope is . Step 4: Substitute those values into the point-slope form. y – y1 = m(x – x1) y – 3 = (x – 1) Which of Talia’s steps is incorrect? Step 1 is incorrect because it uses a point that is not on the line.
