Evaluate x² + 2x - 4 if x = -4.

Answer:

0.2778

Step-by-step explanation:

Each sides in a fair die has a probability of = 1/6

The probability of getting the same number on both dice is 6 from 36 outcomes, that is;

= 6/36 = 1/6

the probability of get same number on both dice after one roll = 1/6

therefore = 1/6 x 1/6 = 1/36 = 0.2778

Answer:

(2.83 , 1 , 4)

Step-by-step explanation:

[tex]2x+2y-z=4\\4x-2y-2z=2\\3x+3y-4z=-4\\[/tex]

Rewrite these equations in matrix form

[tex]\left[\begin{array}{ccc}2&2&-1\\4&-2&-2\\3&3&-4\end{array}\right] \left[\begin{array}{ccc}x\\y\\z\end{array}\right]=\left[\begin{array}{ccc}4\\2\\-4\end{array}\right] \\[/tex]

we can write it like this,

[tex]AX=B\\X=A^{-1}B[/tex]

so to solve it we need to take the inverse of the 3 x 3 matrix A then multiply it by B.

We get the inverse of matrix A,

[tex]A^{-1}=\left[\begin{array}{ccc}7/15&1/6&-1/5\\1/3&-1/6&0\\3/5&0&-2/5\end{array}\right] \\[/tex]

now multiply the matrix with B

[tex]X=A^{-1}B\\\\\left[\begin{array}{ccc}x\\y\\z\end{array}\right] =\left[\begin{array}{ccc}7/15&1/6&-1/5\\1/3&-1/6&0\\3/5&0&-2/5\end{array}\right]\left[\begin{array}{ccc}4\\2\\-4\end{array}\right] \\\\\\\left[\begin{array}{ccc}x\\y\\z\end{array}\right] =\left[\begin{array}{ccc}2.83\\1\\4\end{array}\right] \\[/tex]

Answer:

[tex]LM = 6cm[/tex]

Step-by-step explanation:

[tex]LM = KN[/tex]

[tex]3x =x + 4[/tex]

[tex]3x - x = 4[/tex]

[tex]2x = 4[/tex]

[tex] \frac{2x}{2} = \frac{4}{2} [/tex]

[tex]x = 2[/tex]

then

[tex]LM = 3x[/tex]

[tex]LM =3 \times 2[/tex]

[tex]LM = 6cm[/tex]

Answer:

C: 1

Step-by-step explanation:

14/35 simplified is 2/5. This means 2/5 is equivalent to 14/35. Therefore we have to multiply 2/5 by 1 which is option C.

To find the equation in point-slope of a line passing through two points, we can use the formula: [tex]y - y₁ = m(x - x₁)[/tex] Where (x₁, y₁) are the coordinates of one point, m is the slope of the line, and (x, y) are the coordinates of any other point on the line and  [tex]y-2-(x-5)[/tex] Therefore the correct option is D.

Given that the two points are (5,2) and (-1,-6), we can substitute these values into the formula: [tex]y - 2 = m(x - 5)[/tex](using point 1: ([tex]5,2)) y + 6 = m(x + 1[/tex]) (using point 2: (-1,-6)) Now, let's simplify the equation: y = mx - 5m + 2 (equation 1) y = mx + m - 6 (equation 2) From equations 1 and 2, we can determine that the expected point-slope equation will have the form y - 2 = m(x - 5),

which matches option D. Therefore, the correct point-slope equation of the line passing through the points (5,2) and (-1,-6) is: y - 2 = m(x - 5)

Hence the correct option is D

Hope this helped :)

Step-by-step explanation:

72km/h = 72,000m/3,600s = 20m/s.

Using Kinematics, we have

v = u + at

= (20m/s) + (-2m/s²)(5s)

= 10m/s.

Hence the velocity will be 10m/s. (or 36km/h)

Question: Solve [tex]2(x + 1) = 2x + 5[/tex].

Step 1: Expand.

[tex]2x + 2 = 2x + 5[/tex]

Step 2: Cancel [tex]2x[/tex] on both sides.

[tex]2 = 5[/tex]

Step 3: Since [tex]2 = 5[/tex] is false, there would be no solution.

No Solution

~I hope I helped you :)~

Answer:

No Solution

Step-by-step explanation:

1) Parenthesis

Here, you cannot add x and 1, so you must distribute the 2 into the parenthesis.

(2x+2) = 2x +5

2) Isolate the variable.

To do this, you must subtract 2x from both sides of the equation

2x - 2x + 2 = 2x - 2x + 5

2 = 5

Clearly, this is a false statement, seeing at 2 can never equal 5, the answer is no solution
