Answer:
X = 6
Step-by-step explanation:
17 - 5 = 12
12/2 = 6
hope this helps...
Answer:
6
Step-by-step explanation:
Find x
Try to get x by itself
2x + 5 = 17
subtract 5 on both sides
2×+5(-5)=17(-5)
by subtracting 5 from its opposite, it turns to 0
now we are left with
2x=12
Next we need to divide
2x is like 2(x) which is multiplication
the inverse is division
when we divide, whatever u do to one side u do to the other
2x/2=12/2
×=12/2
we finally got x by itself
we can break 12/2 even further by dividing and you'd get
×= 6

Which equation has the same solution as 10x - x + 5 = 41
Answer:
20x-2x+10=82
Step-by-step explanation:
This is the answer because look all your doing is multiplying the values from the first equation by 2 meaning the proportions of the values are the same resulting in the same solution.

The lines represented by the equations 25y- 20x=100 and 5y - 4x = 20 are
Answer:
The system of equations represent the same line ⇒ B
Step-by-step explanation:
In the system of equations ax + by = c and dx + ey = f, if
a = d, b = e, and c = f, then the system of the equations represent the same linea = d, b = e, and c ≠ f, then the system of the equations represent two parallel linesa ≠ d, and/or b ≠ e, and/or c ≠ f, then the system of the equations represent two intersecting lines∵ The one line represented by the equation 25y - 20x = 100
→ Divide the terms of the equation by 5 to simplify it
∴ 5y - 4x = 20 ⇒ (1)
∴ a = 5, b = -4, c = 20
∵ The other line represented by the equation 5y - 4x = 20 ⇒ (2)
∴ d = 5, e = -4, f = 20
→ Compare the two equations
∵ a = d, b = e, c = f
→ By using the 1st case above
∴ The system of equations represent the same line
Multiply.

What is the nth term rule of the linear sequence below?
7, 9, 11, 13, 15, ...
Tn = 0
Answer:
the best number is 17 cuz the sequence is to add 2 sooo it's 17 then 19
Answer:
2n+5
Step-by-step explanation:
Sequence = 7,9,11,13,15 ....
tn = a + (n-1)d where a is first number, and d is common difference
tn = 7 + (n-1)2
= 7 + 2n - 2
= 2n+5
therefore tn (or nth term rule) = 2n+5
7. In a right angles triangle if an angle measures 35º, then find the
measure of the third angle.
Answer:
55°
Step-by-step explanation:
A right angle is = to 90°
90° + 35° = 125°
Angles in a triangle add up to 180
180 - 125 = 55
Answer:
The answer is 55
Step-by-step explanation:
If all the angles of a triangle add up to 180°, and one of the angles are 35° and another is obviously 90° that means you have to add up the two angles, then subtract that answer from 180°
90 + 35 = 125
180 - 125 = 55
Hope you understand!

Hard qn on Trigonometric equations and identities, please help
Answer:
(i) [tex]OE = 0.6\cdot \sin \theta + 1.4\cdot \cos \theta[/tex], (ii) [tex]\theta \approx 33.368^{\circ}[/tex], (iii) The maximum value of OE is approximately 1.523 meters, which is associated with an angle of approximately 23.199º.
Step-by-step explanation:
(i) From Geometry, we get that sum of internal angles of trangle AOD.
[tex]\angle A + \angle O + \angle D = 180^{\circ}[/tex] (1)
If we know that [tex]\angle O = 90^{\circ}[/tex] and [tex]\angle A = \theta[/tex], then the value of [tex]\angle D[/tex] is:
[tex]\angle D = 180^{\circ}-90^{\circ}-\theta[/tex]
[tex]\angle D = 90^{\circ}-\theta[/tex] (2)
But we also have the following identity:
[tex]\angle D +\angle D' +\angle D'' = 180^{\circ}[/tex] (3)
If we know that [tex]\angle D = 90^{\circ}-\theta[/tex] and [tex]\angle D' = 90^{\circ}[/tex], then the value of [tex]\angle D''[/tex] is:
[tex]90^{\circ}-\theta +90^{\circ}+\angle D'' = 180^{\circ}[/tex]
[tex]\angle D'' = \theta[/tex] (4)
By Trigonometry, we derive the following formula:
[tex]OE = OD +DE[/tex]
[tex]OE = AD\cdot \sin A +CD\cdot \cos D''[/tex] (5)
If we know that [tex]AD = 0.6\,m[/tex], [tex]CD = 1.4\,m[/tex], [tex]A = \theta[/tex] and [tex]D'' = \theta[/tex], then the value of OE is:
[tex]OE = 0.6\sin \theta + 1.4\cos \theta[/tex] (6)
(ii) If we know that [tex]OE = 1.1\,m[/tex], then the value of [tex]\theta[/tex]:
[tex]0.6\cdot \sin \theta + 1.4\cdot \cos \theta = 1.1[/tex]
By trial and error, we find that [tex]\theta \approx 33.368^{\circ}[/tex].
(iii) Let [tex]OE = 0.6\cdot \sin \theta + 1.4\cdot \cos \theta[/tex], the first and second derivatives of the function are, respectively:
[tex]OE' = 0.6\cdot \cos \theta -1.4\cdot \sin \theta[/tex] (7)
[tex]OE'' = -0.6\cdot \sin \theta -1.4\cdot \cos \theta[/tex] (8)
We equalize the first derivative of the function to zero and solve for [tex]\theta[/tex]:
[tex]0.6\cdot \cos \theta - 1.4\cdot \sin \theta = 0[/tex]
[tex]1.4\cdot \sin \theta = 0.6\cdot \cos \theta[/tex]
[tex]\tan \theta = \frac{0.6}{1.4}[/tex]
[tex]\theta \approx \tan^{-1} \frac{0.6}{1.4}[/tex]
[tex]\theta \approx 23.199^{\circ}[/tex]
And we evaluate the second derivative:
[tex]OE'' = -0.6\cdot \sin 23.199^{\circ}-1.4\cdot \cos 23.199^{\circ }[/tex]
[tex]OE'' = -1.523[/tex]
Then, the critical value is associated with an absolute maximum.
The maximum value of OE is:
[tex]OE = 0.6\cdot \sin 23.199^{\circ}+1.4\cdot \cos 23.199^{\circ }[/tex]
[tex]OE \approx 1.523\,m[/tex]
The maximum value of OE is approximately 1.523 meters, which is associated with an angle of approximately 23.199º.

Is Point M the midpoint of AB? Select Yes or No for each statement.
Answer:
A). Yes
B). Yes
C). No
D). Yes
Step-by-step explanation:
Coordinates of the midpoint of a segment joining two points [tex](x_1, y_1)[/tex] and [tex](x_2,y_2)[/tex] are given by [tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex].
A). If the points are A(1, 2) and B(3, 4)
Coordinates of the midpoint M → [tex](\frac{1+3}{2},\frac{2+4}{2})[/tex]
M → (2, 3)
Yes.
B). Extreme points of segment AB are A(0, 8) and B(10, -1)
Coordinates of the midpoint will be,
M → [tex](\frac{0+10}{2}, \frac{8-1}{2})[/tex]
M → (5, 3.5)
Yes
C). Extreme points of segment AB are A(-7, -5) and B(6, 4)
Coordinates of the midpoint will be,
M → [tex](\frac{-7+6}{2}, \frac{-5+4}{2})[/tex]
M → (-0.5, -0.5)
NO
D). Extreme points of segment AB are A(4, -2) and B(6, -8)
Coordinates of the midpoint will be,
M → [tex](\frac{4+6}{2}, \frac{-2-8}{2})[/tex]
M → (5, -5)
Yes
The vertices of ABC are A (-5, 5), B (-2,5), C(-2,3).
1. Graph the figure ABC.
2, Translate each vertex 3 units down and 4 units to left.
3. Draw and label the vertices A'B'C.
Answer:
It will be in the attachment below.
Step-by-step explanation:
Translating a vertex 3 units down and 4 units to the left means that the x coordinate is 4 less than before and the y is 3 less. So, subtract 4 from -5 to get -9; from -2 (twice) to get -6 (twice), and subtract 3 from 5 (twice) to get 2 (twice); from 3 to get 0. So, the new coordinates are (-9, 2), (-6, 2), and (-6, 0). The original shape is in red, and the translated shape is blue.
