Which statement correctly identifies the mistake Joe made? in step 5, Joe should have added 1 to both sides of the equation instead of dividing both sides of the equation by --1. In step 2. Joe should have multiplied the first equation by 2 instead of by 3. in step 4, Joe simplified 27 + (-20) as 7 instead of simplifying to -7. In step 3, Joe multiplied the term -2y by 2 instead of by-2.​

Step-by-step explanation: its not a number  ☺️

Answer:

Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

Step-by-step explanation:

The terms even and odd only apply to integers; 2.5 is neither even nor odd. Zero, on the other hand, is even since it is 2 times some integer: it's 2 times 0. To check whether a number is odd, see whether it's one more than some even number: 7 is odd since it's one more than 6, which is even.

Another way to say this is that zero is even since it can be written in the form 2*n, where n is an integer. Odd numbers can be written in the form 2*n + 1. Again, this lets us talk about whether negative numbers are even and odd: -9 is odd since it's one more than -10, which is even.

Answer: 7.6875 seconds.

Step-by-step explanation:

Let's writhe the motion equations for the rock.

The only force acting on the rock will be the gravitational force, then the acceleration of the rock will be the gravitational acceleration g ≈ 32 ft/s^2

A(t) = -32ft/s^2

Where we have a negative sign because this acceleration pulls the rock downwards.

For the velocity, we must integrate over time, and the constant of integration will be equal to the initial velocity of the rock = 64 ft/s, then the velocity equation is:

V(t) = (-32ft/s^2)*t + 64m/s

For the position, we integrate again over time, and this time the constant of integration will be the initial position, 512ft (Then the water level is at 0 ft)

P(t) = (1/2)*(-32ft/s^2)*t^2 + 64m/s*t + 512 ft

Now we want to find the value of t, the time, such that the rock hits the water.

The rock will land in the water when P(t) = 0ft, becuse we defined the zero in the position as the water.

Then we must solve:

P(t) = 0ft = (1/2)*(-32ft/s^2)*t^2 + 64m/s*t + 512 ft

for t, let's solve this:

0ft = (-16ft/s^2)*t^2 + 64m/s*t + 512 ft

This is a quadratic equation. the two solutions can be found by using the Bhaskara equation, then the solutions will be:

[tex]t = \frac{ -64ft/s +- \sqrt{(64ft/s)^2 - 4*(-16ft/s^2)*512ft} }{2*(-16ft/s^2)} = \frac{-64ft/s +- 192ft/s}{-32ft/s}[/tex]

Then the two solutions are:

t = (-64ft/s + 192ft/s)/(-32ft/s^2) =  -4s      (This time is negative, which is no really defined for this problem, so we can discard this solution)

The other solution is:

t = (-64ft/s - 192ft/s)/(-32ft/s^2) = 7.6875 s

This solution makes sense with the problem, then the answer is 7.6875 seconds.

Answers:

x = 12

angle A = 30 degrees

===========================================================

Explanation:

Check out the attached image below.

Note the pair of (8x+4) angles which are congruent vertical angles.

Also, notice that 50+130 = 180 since those adjacent angles are supplementary. In other words, they form a straight line.

Now that we know the expressions for each interior angle, we add them up and set the sum equal to 180. Recall that for any triangle, the interior angles always add to 180.

Let's solve for x

(3x-6) + (8x+4) + (50) = 180

11x + 48 = 180 .... combine like terms

11x = 180-48 ..... subtract 48 from both sides

11x = 132

x = 132/11 ..... divide both sides by 11

x = 12

Use this to find the value of angle A

A = 3x-6

A = 3*12-6

A = 36 - 6

A = 30

For the sake of completeness, let's find 8x+4 as well. This part is optional

8x+4 = 8*12+4 = 96+4 = 100

The three interior angles of the triangle are: 30, 100, 50

Note how 30+100+50 = 180 to help confirm the answer.

Step-by-step explanation:

4z² + 4z - 15

4z² + 10z - 6z - 15

2z (2z + 5) - 3 (2z + 5)

(2z + 5)(2z - 3)

Answer:

(2z+5) (2z-3)

Step-by-step explanation:

First, multiply the first coefficient by the third.

4*-15=-60

Then find factors of -60 that add up to the middle term.

The factors are: -6 and 10-------> -6*10=-60 and -6+10=4 so -6 and 10 are the correct factors.

Break up the middle term with the factors that you got above. The new equation will be: 4[tex]z^{2}[/tex]-6z+10z-15

Factor by grouping.

First, break the equation into two

(4[tex]z^{2}[/tex]-6z) (10z-15)

Then, factor out the greatest number you can

2z(2z-3) 5(2z-3)

You are then left with a common binomial of 2z-3. COmbine the common binomial into 1 and combine the 2 numbers you factored out in the step above (2z and 5) The final equation will be this:

(2z+5) (2z-3)

The value of y for the given expression 12-(4y+8)=0.5(8y-16) is 3/2.

An expression is a combination of some mathematical symbol such that an arithmetic operator and variable such that all are constrained and create an equation.

As per the given expression,

12-(4y+8)=0.5(8y-16)

12 - 4y - 8 = 4y - 8

4y + 4y - 8 = 12 - 8

8y = 12

y = 12/8 = 3/2

Hence "The value of y for the given expression 12-(4y+8)=0.5(8y-16) is 3/2".

Step-by-step explanation:

The true statement is, the vertex is (1, -5) and the axis of symmetry is x = 1.

Quadratic functions are polynomial functions consisting of variables and exponents and the degree of the variable is 2.

The general form of a quadratic function is f(x) = ax² + b x + c.

Given is a quadratic function,

g(x) = 5x² - 10x

The function written in vertex form is,

g(x) = 5(x - 1)² - 5

Vertex form of a quadratic equation is,

y = a(x - h)² + k, where (h, k) is the vertex.

Here vertex = (h, k) = (1, -5)

Axis of symmetry = -b/2a = -(-10)/10 = 1

Axis of symmetry is, x = 1

Hence the correct option is A.

If it is from figure P to figure O, it is a translation 3 units left and 2 units up

Step-by-step explanation:

Given :

Marisa wants to buy a home in Atlanta with a 30-year mortgage that has an annual interest rate of 4.9%.

The house she wants is $250,000 and she will make a $55,000 down payment and borrow the remainder.

To Find :

What is Marisa's monthly mortgage payment to the nearest dollar.

Solution :

Money remains, m = $( 250000 - 55000 ) = $195000 .

Total price after interest, T = m( 1 + rt )

T = 195000×( 1 + 0.049×1)

T = $204555

Monthly payment,

[tex]M = \dfrac{m}{12}\\\\M = \dfrac{204555}{12}\\\\M =\$ 17046.25[/tex]

Therefore, monthly payment is $17046.25 .

Hence, this is the required solution.
