Select all conditions for which it is possible to construct a triangle. A. Angle measures of 45 degrees, 45 degrees, and 90 degrees B. Triangle with side lengths of 4 cm, 5 cm and a 50 degree angle C. Angle measures of 120 degrees, 20 degrees, and 35 degrees D. Triangle with angle measures of 30 degrees, 60 degrees, and a side length of 3 cm

Answer:

The correct option is O B'

Step-by-step explanation:

We have a quadrilateral with vertices A, B, C and D. A line of reflection is drawn so that A is 6 units away from the line, B is 4 units away from the line, C is 7 units away from the line and D is 9 units away from the line.

Now we perform the reflection and we obtain a new quadrilateral A'B'C'D'.

In order to apply the reflection to the original quadrilateral ABCD, we perform the reflection to all of its points, particularly to its vertices.

Wherever we have a point X and a line of reflection L and we perform the reflection, the new point X' will keep its original distance from the line of reflection (this is an important concept in order to understand the exercise).

I will attach a drawing with an example.

Finally, we only have to look at the vertices and its original distances to answer the question.

The vertice that is closest to the line of reflection is B (the distance is 4 units). We answer O B'

Answer:

The function g(x) that outputs a y value to satisfy the equation -4·x - 6 = -5·y + 2 is g(x) = y = 4/5·x + 8/5

Step-by-step explanation:

The y value of the equation that the required function g(x) outputs = -4·x - 6 = -5·y + 2

Therefore, we have;

-4·x - 6 = -5·y + 2

-5·y + 2 = -4·x - 6

-5·y = -4·x - 6 - 2 = -4·x - 8

Therefore, y = (-4·x - 8)/(-5) = 4/5·x + 8/5

y = 4/5·x + 8/5

Which gives;

g(x) = y = 4/5·x + 8/5

Therefore;

The function g(x) that outputs a y value to satisfy the equation -4·x - 6 = -5·y + 2 is g(x) = y = 4/5·x + 8/5

Answer:

x = 65

Step-by-step explanation:

Corresponding angles always equal each other;

2x + 5 = 135

Subtract 5 from both sides;

2x = 130

Divide both sides by 2;

x = 65

Answer: x = 16   and the measure of angle is 59°.

Step-by-step explanation:

Complementary angles add up to 90 degrees. Meaning that, if you  add the two angles together and add them to equal 90 you can solve for x.

(x + 15) + (3x + 11) = 90       First combine like terms.

4x + 26 = 90   Subtract 26 from both sides.

    -26     -26

4x = 64

x = 16    

If x is equal to 16, then we can find the measure of angle N by inputting the value of x into the expression for the measure of angle N.

m∠N = 3(16) + 11  

m∠N = 48 + 11

m∠N = 59

Answer: The mistake is that david messed up on the inverse operation rules. He should have subtracted 2x, not add, and same goes to adding 2 to 33. He should have subtracted 2 not added it.

Step-by-step explanation:

7x - 2 = 2x + 33

7x - 2x - 2 = 33

5x - 2 = 33

5x = 35

x = 7

Answer:

X^2-x- 8/x+4

Step-by-step explanation:

X+4 becomes a negative 4

Then multiply -4 by the first number which is 1 so -4×1 is -4. Then subtract -4 by the second number 3. This gives you -1 so multiply that by 4 which is -4. Then subtract 4 from the third number -4. So that'll give you -8. Then add an x-value to every number except the very last number as that number will be you remainder.

Answer:

x = 1/a-b.

x is the reciprocal of the difference of a and b.

x is 1 over the difference of a and b.

x is the quotient of 1 and the difference of a and b.

Step-by-step explanation:

i did it

The transformation of the given equation ax = bx + 1 for the x will be 1/(a - b).

In the by substitution method, one of the equations is calculated for one of the variables, which is then transferred back into the other equation where the chosen variable is a replacement, and the second equation is then calculated for. The first variable is then home safely.

In other words, substitution is a method to find the value of variables x and y by just substituting x and y to another equation.

The substitution method is more good than the elimination method.

Given that the equation

ax = bx + 1

Transfer bx to the left side

ax- bx = 1

Take common x from the left-hand side

x(a - b) = 1

Divide a - b on both sides

x = 1/(a - b) hence it will be the correct transformation.

Answer:

The graph of the image is attached below.

Step-by-step explanation:

Let the points of the figure

We need to find the image coordinates after the dilation by a scale factor of 2 centered at the origin.

The rule of dilation by a scale factor of 2 is:

Dilation with scale factor 2, multiply by 2.

(x, y) → (2x,2y)

The coordinates of the vertices of the image according to this rule will be:

(x, y) → (2x,2y)

A(1, -1) → (2(1),2(-1)) = A'(2, -2)

B(3, -1) → (2(3),2(-1)) = B'(6, -2)

C(1, 2) → (2(1),2(2)) = C'(2, 4)

D(3, 2) → (2(3),2(2)) = D'(6, 4)

Therefore, the coordinates of the vertices of the image will be:

Answer:

For WeDeliver= $224

For GoParcels = $56

Step-by-step explanation:

Since we are told his parcel is a cuboid with dimensions 10cm, 20cm, and 40 cm, it means the parcel consists of 4 edges of 10 cm, 4 edges of 20 cm, and 4 edges of 40 cm.

For WeDeliver, the Total Cost is:

Sum, in cm, of the dimensions x 0.80, which is, (10cm *4) + (20cm *4) + (40cm *4)  = 280cm x 0.80 = $224. While

For GoParcels, the Total Cost is:

Total area, in [tex]cm^{2}[/tex], of all 6 faces, x .02

Remember that a cuboid has six (6) faces or sides, so the total area would be gotten by taking note of the length of each visible side of the parcel and then multiplying to get the other side after which we sum after doing so we get:

Total area = [tex]2,800^{cm2}[/tex] * 0.02 = $56
