Answer: {y,x}={2,8}
// Solve equation [2] for the variable y
[2] y = -2x + 18
// Plug this in for variable y in equation [1]
[1] (-2x+18) - x = -6
[1] - 3x = -24
// Solve equation [1] for the variable x
[1] 3x = 24
[1] x = 8
// By now we know this much :
y = -2x+18
x = 8
// Use the x value to solve for y
y = -2(8)+18 = 2
Solution :
{y,x} = {2,8}
How can you solve kx-4=90 for x
Answer:
x = 94/k
Step-by-step explanation:
kx-4=90
Add 4 to each side
kx-4+4=90+4
kx = 94
Divide each side by k
kx/k = 94/k
x = 94/k
Is 1.888... an irrational number? (i have a 1 in math :C)
Answer: No, 1.888 is a rational number. In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers. When the ratio of lengths of two line segments is an irrational number, the line segments are also described as being incommensurable, meaning that they share no "measure" in common, that is, there is no length ("the measure"), no matter how short, that could be used to express the lengths of both of the two given segments as integer multiples of itself.

So i have been bying pepsis for a while and i think 12 pack for 3;50 because if you get 2 packs of 6 it is almost 3;50 with tax and all that so i would go with the 12 pack

Can someone help me please, TEST - Need help
Need help to solve these 2 problems. I need to show the work
THANK YOU
Answer:
14. d
15. b
Step-by-step explanation:
steps for #14:
1. complementary angles are angles that equal 90 degrees when added together. so, those two angles equal 90. make an equation to represent this.
(x + 5) + (x - 9) = 90
2. combine like terms.
2x - 4 = 90
3. solve for x.
2x = 94
x = 47
4. plug x into both formulas to find the measurements of each angle.
47 + 5 AND 47 - 9
d. angle DFG = 52, angle JKL = 38
steps for #15:
1. when angles are linear pairs, it means they equal 180 degrees when added together. so, these two angles equal 180. make an equation to represent this.
(x - 39) + (x + 61) = 180
2. combine like terms.
2x + 22 = 180
3. solve for x.
2x = 158
x = 79
4. plug x into both formulas to find the measurements of each angle.
79 - 39 AND 79 + 61
b. angle 1 = 40, angle 2 = 140

The measure of the angles is 108degrees
Lines and anglesFrom the given diagram, the given measures are alternate exterior angles and they are equal.
Given the following parameters
<A =6x +18
<B = x + 93
Equate
6x + 18 = x + 93
6x - x = 93 -18
5x = 75
x = 15
Determine the measure of the angles
<A = <B = 6x + 18
<A = <B = 6(15) + 18
<A = <B = 108 degrees
Hence the measure of the angles is 108degrees

Which rule describes the composition of transformations that maps ABC to A"B"C"?
O T-6.-2°rx-axis(x, y)
O rx-axis° T-6 -2(x, )
O T-6.-2°Ro, 90°(x,y)
O RO, 90° T -6, -2(x, y)
Answer:
The rule describes the composition of transformations that maps Δ ABC to Δ A"B"C" is rx-axis, T(x - 6, y - 2) ⇒ B
Step-by-step explanation:
Let us revise some rules of transformation
If the point (x, y) reflected across the x-axis, then its image is (x, -y), the rule of reflection is rx-axis (x, y) → (x, -y)If The point (x, y) reflected across the y-axis, then its image is (-x, y), the rule of reflection is ry-axis (x, y) → (-x, y)If the point (x, y) translated horizontally to the right by h units then its image is (x + h, y) ⇒ T (x, y) → (x + h, y)If the point (x, y) translated horizontally to the left by h units then its image is (x - h, y) ⇒ T (x, y) → (x - h, y)If the point (x, y) translated vertically up by k units then its image is (x, y + k)→ (x + h, y) ⇒ T (x, y) → (x, y + k)If the point (x, y) translated vertically down by k units then its image is (x, y - k) ⇒ T (x, y) → (x, y - k)Look at the graph and list the vertice of each triangle
∵ A = (5, -5) and A' = (5, 5)
∵ B = (1, -2) and B' = (1, 2)
∵ C = (1, -5) and C' = (1, 5)
→ The signs of y-coordinates of all vertices of ΔABC are opposite
in ΔA'B'C'
∴ Δ ABC is reflected across the x-axis
∴ The rule is rx-axis (x, y) → (x, -y)
∵ A' = (5, 5) and A" = (-1, 3)
∵ -1 - 5 = -6 and 3 - 5 = -2
∵ B' = (1, 2) and B" = (-5, 0)
∵ -5 -1 = -6 and 0 - 2 = -2
∵ C' = (1, 5) and C" = (-5,3)
∵ -5 - 1 = -6 and 3 - 5 = -2
→ That means every x-coordinate in Δ A'B'C' added by -6 and every
y-coordinate add by -2
∴ Δ A'B'C' is translated 6 units to the left and 2 units down
∴ The rule is T (x, y) → (x - 6, y - 2)
The rule describes the composition of transformations that maps Δ ABC to Δ A"B"C" is rx-axis, T(x - 6, y - 2)
Transformation involves changing the position of a shape.
The transformation rule is (b) rx-axis° T-6 -2(x, y
First, triangle ABC is rotated across the x-axis.
The rule of this transformation is represented as: rx
Next, the resulting shape (i.e. triangle A'B'C') is translated 6 units left and 2 units down.
Using the coordinates of A as a guide, we have:
[tex]\mathbf{A = (5,-5)}[/tex]
Apply the first transformation: Rotate across the x-axis
[tex]\mathbf{A' = (5,5)}[/tex]
Apply the second transformation: Translate 6 units left, and 2 units down
[tex]\mathbf{A" = (5 - 6,5-2)}[/tex]
[tex]\mathbf{A" = (- 1,3)}[/tex]
Hence, the transformation rule is (b)

Find missing angle !.
Answer:
[tex]\huge\boxed{130 \textdegree}[/tex]
Step-by-step explanation:
We can use a couple of angle relationships to find the missing angle.
1. All angles in a triangle add up to 180°
We know that all angle in a triangle will add up to 180°. Since we know the measure of 2, we can find the other angle easily.
[tex]180-35-95\\\\180-130\\\\50[/tex]
So the other angle in the triangle is 50°.
2. The 50° angle and the missing angle are supplementary.
We know that the missing angle and the third triangle angle are supplementary. This means that their angle measures will add up to 180°.
Since we know one, we can find the measure of the other.
[tex]180-50\\\\130[/tex]
So the missing angle is 130°.
