Answer:
x= -1/2
Step-by-step explanation:
(2x-4)+(12x-3)=0
2x+ 12x - 4-3=0
14x=0-7
14x =-7
x= -7/14
x= -1/2

Answer:
(0, 19)
Step-by-step explanation:
Find the equation.
Find the slope:
[tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
22-16/1-(-1) = 6/2 = 3
Here's our equation so far:
y = 3x + b
Find b by plugging in one pair of (x,y) coordinates.
22 = 3(1) + b
22 = 3 + b
b = 19
Now we now the equation:
y = 3x + 19
So, the y-intercept is 19.
−2x=x2−6 Rewrite the equation by completing the square.
Answer:
(x + 1)² = 7
Step-by-step explanation:
Given:
-2x = x² - 6
We'll start by rearranging it to solve for zero:
x² + 2x - 6 = 0
The first term is already a perfect square so that's fine. Normally, if that term had a non-square coefficient, you would need to multiply all terms a value that would change that constant to a perfect square.
Because it's already square (1), we can simply move to the next step, separating the -6 into a value that can be doubled to give us the 2, the coefficient of the second term. That value will of course be 1, giving us:
x² + 2x + 1 - 1 - 6 = 0
Now can group our perfect square on the left and our constants on the right:
x² + 2x + 1 - 7= 0
x² + 2x + 1 = 7
(x + 1)² = 7
To check our answer, we can solve for x:
x + 1 = ± √7
x = -1 ± √7
x ≈ 1.65, -3.65
Let's try one of those in the original equation:
-2x = x² - 6
-2(1.65) = 1.65² - 6
- 3.3 = 2.72 - 6
-3.3 = -3.28
Good. Given our rounding that difference of 2/100 is acceptable, so the answer is correct.
Mhanifa please help! Explain how you can use the perpendicular bisector of a segment to draw an isosceles triangle.
Answer:
If you construct the perpendicular bisector of a line segment, every point on the perpendicular bisector will be the same distance from both point A and point B.
To construct an isosceles triangle, you can start from any point on the perpendicular bisector and draw line segments to point A and to point B
The required steps are in the solution that to use the perpendicular bisector of a segment to draw an isosceles triangle.
What is an isosceles triangle?An isosceles triangle is defined as a triangle with two sides of equal length.
To use the perpendicular bisector of a segment to draw an isosceles triangle, you can follow these steps:
Draw the segment for which you want to find the perpendicular bisector.
Use a compass to draw a circle with its center at the midpoint of the segment.
With the compass still set to the same radius, draw two arcs that intersect the segment at two points. These points will be the base points of the isosceles triangle.
Draw a line through the midpoint of the segment and the point where the arcs intersect the segment. This line is the perpendicular bisector of the segment.
Use a ruler to draw a line segment connecting the base points of the isosceles triangle.
Use a ruler to draw a line segment connecting the apex of the isosceles triangle (the point where the perpendicular bisector intersects the base) to one of the base points.
At this point, you should have a triangle with two equal sides and a right angle at the apex. This is an isosceles triangle.

ab=195
Step-by-step explanation:
An angle measures 27.2° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
Step-by-step explanation:
Supplementary angles have a sum of 180 degrees.
a+a-27.2=180
2a-27.2=180
2a=207.2
a=103.6, and since b=a-27.2
b=76.4
So one angle is 103.6 degrees and the other is 76.4 degrees.
A certain television is advertised as a 10-inch TV (the diagonal length). If the width of
the TV is 6 inches, how many inches tall is the TV?
Answer:
8 in
Step-by-step explanation:
Given data
DIagonal= 10 in
Width= 6 in
`Height=???
We know that the expression that can be used to find the missing dimension is given as
d^2= w^2+h^2
substitute
10^2=6^2+h^2
100= 36+h^2
100-36= h^2
64= h^2
h= √64
h= 8 in
Hence the height is 8 in

Answer:
option c is the correct answer
Answer:
C consecutive angle
Step-by-step explanation:
Read the problem below. Type in your answer on the box.
The length of a rectangle is (3x - 1) and its width is ( 2x + 5). What is the area of the rectangle?
Answer:
3x^2 + 13x - 5
Step-by-step explanation:
To find the area, you multiply the length by width. So its is (3x - 1) * (2x + 5)
Then distribute. (3x * 2x) + (3x *5) + (-1 *2x) + (-1 * 5)
So 3x^2 + 15x -2x -5
Final Answer: 3x^2 + 13x - 5

If EBCD is a parallelogram, EB = 16, ED = 25, BF = 11, EC = 34, mZBED = 55°, mZCDB = 67°,
and mZBCE = 24º, find each missing measure.

mZEBD =
F
FC =
E
D
mZBEC =
mZDBC =
CD =
Answer:
1. BC = 25
2. m∠EDC = 125°
3) BD = 22
4) m∠EBD = 67°
5) FC = 17
6) m∠BEC = 24°
7) CD = 16
8) m∠DBC = 58°
Step-by-step explanation:
The dimensions of parallelogram EBCD are;
EB = 16, ED = 25, BF = 11, EC = 34, m∠BED = 55°, m∠CDB = 67°
1. BC = ED = 25 Opposite sides of a parallelogram are equal
2. m∠BCD = m∠BED = 55 opposite angles of a parallelogram are equal
m∠BCD + mEDC = 180° adjacent sides of a parallelogram are supplementary
m∠EDC = 180° - m∠BCD
∴ m∠EDC = 180° - 55° = 125°
m∠EDC = 125°
3) BD = BF × 2 Diagonals of a parallelogram bisect each other
∴ BD = 11 × 2 = 22
BD = 22
4) m∠EBD = m∠CDB = 67° from alternate angles between parallel lines
5) FC = EC/2 from diagonals of a parallelogram bisect each other
∴ FC = EC/2 = 34/2 = 17
FC = 17
6) m∠BEC = m∠BCE = 24° Alternate angles between parallel lines
m∠BEC = 24°
7) CD = EB = 16 Opposite sides of a parallelogram are equal
8) m∠EBC = m∠EDC = 125° from opposite angles of a parallelogram are equal
m∠DBC + m∠EBD = m∠EBC from angle addition postulate
∴ m∠DBC = m∠EBC - m∠EBD
m∠DBC = 125° - 67° = 58°
m∠DBC = 58°
