What is the slope of the line through -5,7 and -5,-8
Answer:
Undefined
Step-by-step explanation:
Answer:
[tex]slope = \frac{-15}{0}[/tex] = Undefined
Step-by-step explanation:
To find the slope of these two points we use the slope formula
[tex]slope = \frac{(y_{2} - y_{1})}{(x_{2}-x_{1})}[/tex]
[tex]slope = \frac{((-8) - 7)}{((-5)-(-5))}[/tex]
[tex]slope = \frac{-15}{0}[/tex] The slope would be classified as undefined

The plane region is revolved completely about the x-axis to sweep out a solid of revolution. Describe the solid AND find its volume in terms of π.
Answer:
C
Step-by-step explanation:
what happens, when you rotate something around a pole ? what shape is the most outside point making around that pole ?
a circle, of course.
that means rotating the rectangle around the x-axis creates a round object (with the bottom area being a circle).
so, all answers about a prism (rectangular bottom shape) are automatically wrong.
again, just imagine to rotate a small sheet of paper around a pole (the x-axis acts like one in this scenario).
the result is a solid with a circular bottom area, and it maintains this shape all the way to the top.
it is a cylinder !
and what is its radius ?
well, the outermost point of the rectangle is 8 points away from the x-axis. when we rotate this rectangle, that attribute remains, of course. and every point on the side surface of the resulting cylinder has the same distance from the central x-axis : 8.
so, the radius is 8.
and the volume of a cylinder is
ground area × height = pi×r² × height
in our case
pi×8² × 5 (the width or "height" of the rectangle) = pi×64 × 5 = 320×pi
(x-4)(x+3)(x+4) simplify
Answer:
x^3 + 3x^2 - 16x - 48.
Step-by-step explanation:
(x - 4)(x + 3)(x + 4)
= (x - 4)(x + 4)(x + 3)
= (x^2 - 16)(x + 3)
= x^3 + 3x^2 - 16x - 48.

4/10+8/100 i need help
Answer:
12/25
Step-by-step explanation:
Multiply both the numerator and denominator of each fraction by the number whom makes its denominator equal the LCD.
[tex]\left(\frac{4 \cdot 10}{10 \cdot 10} \right) + \left(\frac{8 \cdot 1}{100 \cdot 1}\right) = \frac{40}{100} + \frac{8}{100}[/tex]
[tex]= \frac{48}{100}[/tex]
Find the new LCD(4).

Some pedometers have a default setting that assumes that the number of steps a person must take to walk 1 mile decreases by 33 steps per 1 inch increase in height. Suppose a person 72 inches tall makes 2,250 steps per mile.
A. Find a linear model of the number of steps S per mile as a function of height h (in inches).
S = ______
B. Use the model to predict the number of steps per mile a person who is 68 inches tall will take.
The number of steps per mile for a person who is 64 inches tall will be 2354.
What is Algebra?Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.
Some pedometers have a default setting that assumes that the number of steps a person must take to walk 1-mile decreases by 33 steps per 1-inch increase in height.
Suppose a person 72 inches tall makes 2,250 steps per mile.
70 inches tall makes 2150 steps per 1 mile.
For every inch of height gain, the count of steps required to walk a mile drops by 34.
If the count of steps is S and the height is h, we have the following issue.
S = 2150 - 34(h -70)
Therefore the linear model will be
S = 2150 -34(h - 70)
Now for h = 64, we have
S = 2150 - 34(64 - 70)
S = 2150 - 34 ( -6)
S = 2150 + 204
S = 2354
The number of steps per mile for a person who is 64 inches tall will be 2354.

5 to the power of 7 divided by 5 to the power of minus 2 equals what? As the exponent like 5 to the power of what is the answer?
Answer:
5 to the power of 9
Step-by-step explanation:
You have 5^7 over 5^-2.
The 5^-2 on the bottom can be handled by moving the whole thing UP across the fraction bar. This makes the -2 exponent into a positive 2 exponent.
5^7 / 5^-2
= 5^7• 5^2
Now, to multiply these, ADD the exponents.
5^7•5^2
= 5^9
Let f(x) = x² + 7x + 12.

Evaluate: f(-3) =
Answer:
f(-3) = 0
Step-by-step explanation:
The question is asking you to evaluate the function when x = -3. Therefore, substitute -3 in for x and simplify.
f(x) = x² + 7x + 12 <---- Original equation
f(-3) = (-3)² + 7(-3) + 12 <---- Substitute -3 for x
f(-3) = 9 + 7(-3) + 12 <---- Square -3
f(-3) = 9 - 21 + 12 <---- Multiply 7 x -3
f(-3) = 0 <---- Combine terms

Step-by-step explanation:
Solve the system of equations by substitution.
Given equations:
x + y = 15 . . . . . . . . (1)y = 4x . . . . . . . . . . . (2)To find :
value of xvalue of yPut value of y of second equation (i.e y = 4x) in equation one (i.e x + y = 15)
➞ x + y = 15
➞ x + 4x = 15
➞ 5x = 15
Divide both LHS and RHS by 5
➞ (5x)/5 = 15/5
➞ x/1 = 3/1
➞ x = 3
Now put value of x in equation 2
{Note : value of x can be inserted both in equation 1 and 2}
➞ y = 4x
➞ y = 4 × 3
➞y = 12
Verification :
put value of x and y in equation 1 :
x + y = 1512 + 3 = 1515 = 15LHS = RHS
hence verified !
put value of x and y in equation 2 :
y = 4x12 = 4 × 312 = 12LHS = RHS
hence verified !
∴ Value of x and y is 3 and 12 respectedly .
REQUIRED ANSWER :
(x , y) = (3 , 12)
Answer:
(3, 12)
Step-by-step explanation:
Given equations:
Equation 1: x + y = 15Equation 2: y = 4xSubstitute Equation 2 into Equation 1 and solve for x:
⇒ x + 4x = 15
⇒ 5x = 15
⇒ x = 15 ÷ 5
⇒ x = 3
Substitute the found value of x into Equation 2 and solve for y:
⇒ y = 4(3)
⇒ y = 12
Therefore, the solution of the system is (3, 12)

identify an equation in slope-intercept form for the line parallel to y=1/4x-7 that passes through (-2,-6)
Answer:
D. [tex]y + 6 =- \frac{1}{4} (x+2)[/tex]
Step-by-step explanation:
We are given that a line is parallel to the line y=-1/4x-7 and passes through (-2, -6).
We want to write the equation of this line.
First, we need to know that parallel lines have the same slope.
In y=-1/4x-7, the slope of the line is -1/4; it is also the slope of the line parallel to it.
All of the answers in your system are written in point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point
As we already know the slope and the point, we can plug these values into the formula.
Starting with the slope; as found above, the slope is -1/4. Therefore, the equation will then be:
[tex]y-y_1=-\frac{1}{4} (x-x_1)[/tex]
Now substitute -2 and -6 as [tex]x_1[/tex] and [tex]y_1[/tex] respectively (note: we have NEGATIVE numbers, and SUBTRACTION in the formula, so we will end up subtracting a negative).
[tex]y--6=-\frac{1}{4} (x--2)[/tex]
We can simplify this to become:
[tex]y+6=-\frac{1}{4} (x+2)[/tex]
Therefore, D is the answer.
Answer:
y+6= -4(x+2)

Explain your reasoning. (2 points)
It is not possible for Jackie to have spent 45 minutes dancing if she runs and dances for a total of exactly 55 minutes and dances for 25 minutes longer than she runs.
System of equationsThese are equations that is made of unknown variables.
Let the time she dances be x
Let the time she runs be y
If Jackie runs and dances for a total of 55 minutes every day, the;
x + y = 55 ............ 1
If She dances for 25 minutes longer than she runs, then;
x = y + 25 ............. 2
The pair of equation are x + y = 55 and x = y + 25
Substitute 2 into 1
y + 25 + y= 55
2y .= 30
y = 15
He spent 15 minutes running everyday
x = 55 - 15
x= 40minutes
