Find the value of x or y so that the line passing through the two points has the given slope
16. (-3, y), (-9, -2); m = 1
Answer:
(-3, -2)
Step-by-step explanation:
To find the value of y so that the line passing through the two given points has a slope of 1, we can use the formula for the slope of a line, which is given by:
m = (y2 - y1) / (x2 - x1)
In this case, we know that the slope of the line is 1, so we can set up the equation:
1 = (y - (-2)) / (-9 - (-3))
Solving for y, we get:
1 = (y + 2) / 6
Therefore, y = 1 * 6 - 2 = 4, so the value of y that we are looking for is 4.
Alternatively, we can use the two given points to write the equation of the line in slope-intercept form, which is given by:
y = mx + b
In this case, we know that the slope of the line is 1, so we can write the equation as:
y = x + b
We also know the coordinates of one of the points on the line, (-3, y), so we can substitute these values into the equation to solve for b:
y = (-3) + b
Substituting the value of y that we found earlier, 4, we get:
4 = (-3) + b
Solving for b, we get:
b = 4 + 3 = 7
Therefore, the equation of the line that passes through the two given points and has a slope of 1 is y = x + 7. This equation is in slope-intercept form, so it shows us the value of y when x is 0, which is 7. Since the y-coordinate of one of the given points is -2, we know that this point must be (-3, -2), and we can verify that this point satisfies the equation y = x + 7.
Which of the following is the value of the discriminant for 2x² 5x 7 0?
The value of the discriminant for 2x² + 5x + 7 = 0 is -31.
The discriminant of a quadratic equation is the part of the equation used to determine the number and type of solutions. It is calculated by subtracting 4 times the coefficient of the squared term, a, from the coefficient of the linear term, b, squared. This is then divided by four times the coefficient of the squared term, a.
In this case, the equation is 2x² + 5x + 7 = 0.
The discriminant for this equation is calculated as follows:
Discriminant = b² - 4ac
Discriminant = (5)² - 4(2)(7)
Discriminant = 25 - 56
Discriminant = -31
Therefore, the value of the discriminant for 2x² + 5x + 7 = 0 is -31.

What is the quotient of x³ 3x² 3x 2 X² x 1 )?
To simplify the denominator, we can subtract the common terms - x² and x - leaving us with just x. We can then combine our simplifications to form the final answer of x + 2, then the quotient is x³ + 3x² + 3x + 2 / x² + x = x + 2
x³ + 3x² + 3x + 2
x² + x
Simplifying the numerator:
x³ + 2x² + 3x + 2 - x² - x = x² + 2x + 2
Simplifying the denominator:
x² + x - x = x
Final Answer:
x + 2
The expression x³ 3x² 3x 2 X² x 1 is a fraction, with the numerator being x³ 3x² 3x 2 and the denominator being X² x 1. To solve this expression, we need to simplify both the numerator and the denominator. To simplify the numerator, we can subtract the common terms - x² and x - leaving us with x² + 2x + 2. To simplify the denominator, we can subtract the common terms - x² and x - leaving us with just x. We can then combine our simplifications to form the final answer of x + 2.

A tank containing 100 gallons of brine made by dissolving 6 pounds of salt in water. Salt water containing one (1) pound of salt per gallon runs in at the rate of 2 gallons per minute. A well stirred mixture runs out at the rate of 2 gallons per minute. Find the amount of salt in the tank at the end of one hour.
The amount of salt in the tank at the end of one hour is 103 lbs .
Given
Initially there are 100 gal in the tank. There are 6 lbs of salt. The concentration of salt in the tank is 6/100 or 0.06 lbs per gal.
Water flowing in has concentration of 1 lb/gal.
Water flowing out has unknown concentration because mixture is constantly changing.
Tank is losing 1 gal per minute. ( 2 - 2 = 0 )
V ( t ) = 100 - t
s ( t ) = 6 + 2t − 3t ∗ C( t )
C ( t ) = s ( t ) / V ( t )
= 100 - t / 2t − 2t ∗ C( t )
= 6 + 2t / 100 + 2t
After 60 minutes
C ( t ) = 6 + 2 * 60 / 100 + 2 * 60
= 6 + 120 / 100 + 120
= 126 / 220
= 63 / 110
Salt content s( t ) = 6 + 2 * 60 - 3 * 60 * 63 / 110
= 126 - 180 * 63 / 110
= 126 - 103

What is the value of the polynomial 4x² 7x 5 when x 3?
When X=3 a polynomial has a value of 61 and when X=3 a value of 143.
Given that,
Let p(x)=3x²−4x²+7x−5 is our polynomial.
Polynomials are algebraic expressions made up of coefficients and variables. Occasionally, variables are referred to as indeterminates. For polynomial expressions, addition, subtraction, multiplication, and positive integer exponents are all possible; however, division by variable is not. x2+x-12 is an illustration of a single-variable polynomial. Three terms are involved in this example: x2, x, and -12.
Substitute x=3 in above expression,
∴p(3)=3(3) 3−4(3) 2 +7(3)−5
=3(27)−4(9)+21−5
=81−36+21−5
=61
Now,
p(−3)=3(−3)
3 −4(−3) 2 +7(−3)−5
=3(−27)−4(9)−21−5
=−81−36−21−5
=−143
So, value of polynomial when X=3 is 61 and when x=−3 is −143

Natalie works in a toy shop and earns $43 per day. She earns an extra $3 for each toy she sells. If Natalie wants to earn at least $70 per day, which inequality shows the minimum number of toys, n, that she should sell?
43 + 3n ≥ 70, so n ≥ 9
43 + 3n ≤ 70, so n ≤ 9
43 + 3n ≥ 70, so n ≥ 24
43 + 3n ≤ 70, so n ≤ 24
Answer:
Hello! Natalie earns a fixed amount of $43 per day. She earns $3 more every toy she sells. Basically, you can set up this equation as 43 + 3n >= 70. This is because she wants to make a least $70 and earns $3 each for "n" toys that she sells. When you solve the inequality, the answer is 9. Subtract 43 from both sides to get 3n >= 37 and divide by 3 to get n >= 9. The answer is A.

the volume of the cone in 270 pi
Answer:

Step-by-step explanation:
The solid shape is composed of a cone and a hemisphere.
Let's work out the radius of the cone since the hemisphere and the cone share the same radius.
Let the radius be r cm.
Volume of cone= [tex] \displaystyle{\frac{1}{3} \pi {r}^{2} h}[/tex]
Substituting the volume and height of the cone:
[tex]270\pi = \displaystyle{\frac{1}{3} (\pi)( {r}^{2} )(10)}[/tex]
Simplify:
[tex] \frac{10}{3} {r}^{2} = 270[/tex]
[tex]81 = {r}^{2} [/tex]
Square root both sides:
[tex]r = \sqrt{81} [/tex]
r= 9
The volume of a hemisphere is half the volume of a sphere.
Volume of hemisphere
[tex] = \displaystyle{ \frac{1}{2}( \frac{4}{3} )(\pi )( {r}^{3}) }[/tex]
[tex] = \displaystyle{ \frac{2}{3}\pi {r}^{3} }[/tex]
Substituting the value of r:
Volume of hemisphere
[tex] = \displaystyle{ \frac{2}{3} (\pi)(10^{3} )}[/tex]
[tex] = \displaystyle{ \frac{2}{3}(1000)(\pi) }[/tex]
[tex] = \displaystyle{\frac{2000}{3} \pi}[/tex]
Volume of the shape

How many solutions does the pair of equations 3x 2y 5 2x 3y 7 have?
The pair of linear equations 3x+2y= 5 and 2x-3y= 7 have one unique solution.
The number of solutions for a pair of equations can be determined by looking at the coefficients of the variables in the equations. In particular, the number of solutions will depend on whether the coefficients of the variables are the same or different.
In this case, the pair of equations 3x+2y= 5 and 2x-3y= 7 have different coefficients for the variables x and y. Specifically, the coefficient of x is 3 in the first equation and 2 in the second equation, and the coefficient of y is 2 in the first equation and -3 in the second equation.
When the coefficients of the variables are different, there is exactly ONE solution to the system of equations. This is because the two equations will intersect at a single point in the x-y plane, which is the solution to the system of equations.
Therefore, based on the coefficients of the variables in the equations 3x+2y= 5 and 2x-3y= 7, we can conclude that there is only ONE solution to this system of equations.
