Step-by-step explanation:

Answer:

y = - 5x - 6

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 )

Here m = - 5 and c = - 6, thus

y = - 5x - 6 ← equation in slope- intercept form

The slope intercept form is y = -5x-6

Given, y-intercept = (0, -6) & slope of the line = -5

The general form of an equation of line is, y = mx+c

where, m is the slope of the line & c is the y intercept

So, when x = 0 , y = -6

So, the line above passes through the point (0, -6)

Therefore, The slope intercept form is, y = -5x-6

Answer:

[tex]\frac{x+2}{x-1}[/tex]

Step-by-step explanation:

Factorise the numerator and denominator

2x² + 2x - 4 ← factor out 2 from each term

= 2(x² + x - 2)

= 2(x + 2)(x - 1) ← in factored form

2x² - 4x + 2 ← factor out 2 from each term

= 2(x² - 2x + 1)

= 2(x - 1)² ← in factored form

Thus

[tex]\frac{2x^2+2x-4}{2x^2-4x+2}[/tex]

= [tex]\frac{2(x+2)(x-1)}{2(x-1)^2}[/tex]

Cancel 2 and factor (x - 1) on numerator/ denominator, leaving

Answer:

Step-by-step explanation:

-3.3m = -1.1

Divide both sides by -3.3

m = -1.1

-3.3

The solution to the equation -3.3m = -1.1 is m = 1/3 or approximately 0.33. This was determined by dividing both sides of the equation by -3.3.

The problem -3.3m = -1.1 is a simple one-step equation which can be solved by isolating the variable. Here the variable is m. Dividing both sides of the equation by -3.3, we get m = (-1.1/-3.3). This simplifies to m = 1/3 ≈ 0.33. So, the solution to the equation is m = 0.33.

Answer:

45 Miles

Step-by-step explanation:

Speed = Distance / Time

Distance = Speed * Time

= 7.5 * 6 = 45 Miles

Final answer:

To find the distance traveled by the bicycle rider, multiply the average speed of 7.5 mph by the time of travel of 6 hours, resulting in a total distance of 45 miles.

Explanation:

Calculating Distance Traveled

To calculate the distance traveled by the bicycle rider, we use the formula that relates average speed, distance traveled, and time of travel:

Average speed = Distance traveled / Time of travel

In this scenario, the bicycle rider's average speed is given as 7.5 mph, and the time of travel is 6 hours. Therefore, the distance traveled can be calculated by multiplying the average speed by the time of travel:

Distance traveled = Average speed × Time of travel

Distance traveled = 7.5 mph × 6 h = 45 miles

Therefore, the bicycle rider traveled a total of 45 miles.

Final answer:

In the number 5,291, the digit 5 is in the thousands place (value of 5,000), the digit 2 is in the hundreds place (value of 200), the digit 9 is in the tens place (value of 90), and the digit 1 is in the ones place (value of 1).

Explanation:

The place value of a digit in a number indicates the value of the digit based on its position relative to the other digits. For example, in the number 5,291, the digit 5 is in the thousands place, which means its value is 5,000. Similarly, the digit 2 is in the hundreds place, so its value is 200; the digit 9 is in the tens place, so its value is 90; and the digit 1 is in the ones place, which means its value is simply 1.

Step-by-step explanation:

To solve this system of equations, you can use either substitution or elimination. Let's use the elimination method.

First, multiply the second equation by 4 to make the coefficients of \( x \) in both equations opposites:

\( (2x + 5y) \times 4 = -28 \times 4 \)

This gives us:

\( 8x + 20y = -112 \)

Now, we'll subtract the first equation from this modified second equation:

\( (8x + 20y) - (-8x + 15y) = -112 - (-28) \)

Simplify:

\( 8x + 20y + 8x - 15y = -112 + 28 \)

\( 16x + 5y = -84 \)

Now we have a new equation:

\( 16x + 5y = -84 \)

And the first equation remains the same:

\( -8x + 15y = -28 \)

Now, we can solve this system of equations by elimination or substitution. Let's continue with elimination. Multiply the first equation by 2:

\( -16x + 30y = -56 \)

Now, add this equation to the second modified equation:

\( (-16x + 30y) + (16x + 5y) = -56 - 84 \)

\( 30y + 5y = -140 \)

\( 35y = -140 \)

Divide both sides by 35:

\( y = -4 \)

Now, substitute \( y = -4 \) into one of the original equations to solve for \( x \). Let's use the first equation:

\( -8x + 15(-4) = -28 \)

\( -8x - 60 = -28 \)

Add 60 to both sides:

\( -8x = -28 + 60 \)

\( -8x = 32 \)

Divide both sides by -8:

\( x = -4 \)

So, the solution to the system of equations is \( x = -4 \) and \( y = -4 \).

To solve, find how many groups of 5 are in 145 girls (145 ÷ 5 = 29 groups of girls). Then, find how many boys are in these groups by multiplying the number of groups by the boys' ratio (4), thus 29 x 4 = 116 boys in the 6th grade.

To determine the number of boys in the 6th grade, we will make use of the ratio provided, 4:5. This ratio means that for every 4 boys, there are 5 girls. To translate this into actual numbers, take the total number of girls (145) and calculate how many groups of 5 you have, because that's how many groups of boys you would have also. To determine the number of boys, you multiply the number of groups by 4.

First, Divide 145 by 5 to find out how many groups of girls there are: 145 ÷ 5 = 29. These equate to groups of students based on the ratio. Second, Multiply the number of groups by the boys’ ratio number (4) to find the number of boys. So, 29 x 4 = 116. That's the total number of boys in the 6th grade.

Final answer:

The volume of foam needed to make 120 cones, each with a 9-inch height and a 5-inch diameter base, is approximately 7,068.6 cubic inches.

Explanation:

The question involves finding the volume of a single cone and then calculating the total volume of foam needed for producing 120 cones. To find the volume of one cone, we use the formula V = (1/3)πr²h, where r is the radius of the base and h is the height. Given that the diameter of the base is 5 inches, the radius (r) would be half of that, which is 2.5 inches. The height (h) is given as 9 inches. Therefore, the volume of one cone is:

V = (1/3)π(2.5)²(9)

This simplifies to V ≈ 58.905 cubic inches (using 3.14159 for π). To find the volume for 120 cones, we multiply the volume of one cone by 120:

Total volume = 58.905 in³ × 120 ≈ 7,068.6 cubic inches.

This is the amount of foam needed to make 120 cones.
