Answer:
x = - 8, x = 2 are the solutions
Step-by-step explanation:
Given
x² + 6x - 16 = 0
Consider the factors of the constant term (- 16) which sum to give the coefficient of the x- term (+ 6)
The factors are + 8 and - 2 , since
8 × - 2 = - 16 and 8 - 2 = + 6 , thus
(x + 8)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 8 = 0 ⇒ x = - 8
x - 2 = 0 ⇒ x = 2

2x - 5y + 3z = 27
4x + 3y - 7z=-37
x - 2y + 5z = 30
I need help solving this with cramers rule
Step-by-step explanation: answer {x,y,z} = {1,-2,5}
/ Solve equation [3] for the variable x
[3] x = 2y - 5z + 30
// Plug this in for variable x in equation [1]
[1] 2•(2y-5z+30) - 5y + 3z = 27
[1] - y - 7z = -33
// Plug this in for variable x in equation [2]
[2] 4•(2y-5z+30) + 3y - 7z = -37
[2] 11y - 27z = -157
// Solve equation [1] for the variable y
[1] y = -7z + 33
// Plug this in for variable y in equation [2]
[2] 11•(-7z+33) - 27z = -157
[2] - 104z = -520
// Solve equation [2] for the variable z
[2] 104z = 520
[2] z = 5
// By now we know this much :
x = 2y-5z+30
y = -7z+33
z = 5
// Use the z value to solve for y
y = -7(5)+33 = -2
// Use the y and z values to solve for x
x = 2(-2)-5(5)+30 = 1

(x=9.8-2.4)
x=7.4
Answer:
7.4
Step-by-step explanation:
2.4+x=9.8
subtract 2.4 from both sides to get:
x=7.4

the addition property of equality and then the division property of equality
the addition property of equality and then the multiplication property of equality
the subtraction property of equality and then the division property of equality
the subtraction property of equality and then the multiplication property of equality
Answer:
The right answer is:
the addition property of equality and then the division property of equality
Step-by-step explanation:
Given equation and steps to solve it are:
Step 1: –3x – 5 = 13
Step 2: –3x = 18
Step 3: x = –6
In step two, -5 has to be removed from left hand side of the equation so additional property of equality will be used i.e. adding 5 on both sides
Similarly in the third step, to remove -3 with x , division property of equality will be used i.e. dividing both sides by -3
Hence,
The right answer is:
the addition property of equality and then the division property of equality
Answer:
A) the addition property of equality and then the division property of equality

Constant: -16
Coefficients: 4, 1, 4, -1
Step-by-step explanation:
Terms:
just substitute the '+' and '-' with comma.

Variables:
just list the letters (only)
For example: 8y-7+2y becomes x, y
Constants:
it is the number by themselves, no letter
For example: 5-4x-8y becomes just 5
Coefficients:
the number in front of letter (dont forget the sign, also if no number such as 'b', the coefficient is 1 because we dont typically write 1, it is assumed it goes there)
For example: 6m-2n+7 becomes 6 and -2
Is this a function (1,17),(0,16),(0,15),(-2.17)

In triangle BCD overline BC cong overline BD ,m angle B=13x-35 , m angle C=5r-19 and m angle D=2r+14 , find x and the measure of each angle.
Answer:
136
Step-by-step explanation:
Answer:
The measure of m<B, m<C and m<D are 108, 36 and 46
Step-by-step explanation:
What are triangles?
From the triangle BCD, if BC=BD, then
m<C = m<D (Base angles are equal)
Given the following paramters:
m<C = 5x-19
m<D = 2x + 14
Hence;
5x - 19 =2x + 14
5x- 2x = 14 + 19
3x = 33
x = 11
m<B = 13x - 35
m<B = 13(11) - 35
m<B = 108 degres
m<C = 5x - 19
m<C = 55- 19
m<C = 36
m<D = 180 - 144
m<D = 36 degreees

Answer:
K(1,0), L(2, 3), M(-1, 4), N(-2,1)
Step-by-step explanation:
Because the points are being flipped over the x-axis the y values remain the same, but the x values are multiplied by -1. Multiplying the values by -1 will switch a negative value positive and a positive value negative. This will correctly flip the points to the opposite side of the graph.

Explain the steps to solve for g in the equation −1/3g+5=2 .
Answer:
g = 9. I hope that I help my buddy out :)
Answer:
g=9
Step-by-step explanation:
Step 1: Subtract 5 from both sides.
-1/3g=5-5=2-5
-1/3g=-3
Step 2: Multiply both sides by 3/(-1).
(3/-1) x (-1/3g)=(3/-1) x (-3)
ANSWER g=9
