Tell whether the ordered pair (2, -5) is a solution of the system:
x + 3y = -13
4x + y = 3

yes or no

Answer:

107

Step-by-step explanation:

Since we know that the triangles have the same 3 sides, they are congruent (SSS). We also know that a triangle's angles add up to 180 degrees.

We first need to add 41 and 32 to give us the number we need to subtract from 180.

41+32=73

Now we need to subtract from 180 degrees.

180-73=107

If 107 is the measure of angle D, then according to SSS congruence it is also the measure of angle B.

Answer:

One-fourth equals three-twelfths

Step-by-step explanation:

From the above question:

The fractions

One-fourth

: A fraction bar divided into 4 parts. 1 is shaded.

One-half

A fraction bar divided into 2 parts. 1 is shaded

Three-twelfths:

A fraction bar divided into 12 parts. 3 are shaded.

Which is a correct comparison of these fractions?

Comparing the options

a) One-fourth equals three-twelfths

= 1/4 = 3/12

Divide numerator and denominator by 3

= 3 ÷ 3 /12 ÷ 3

= 1/4

Option a is correct

b) One-half is less than three-twelfths

1/2 < 3/12

This statement above is wrong.

One half is greater than three twelfths

1/2 is > 3/12

1/2 > 1/4

c) One-fourth is greater than one-half

1/4> 1/2

This statement above is wrong.

1/2 is greater than 1/4

d) Three-twelfths is greater than one-fourth

This is statement is wrong. Three -twelfths is equal to one - fourths

The correct comparison of these fractions is One-fourth equals three-twelfths.

1.180-85=x

2.90-30=x

3. It looks about the same as 70 souhhh yeahhhhh

4. 180-105

5. actually im not sure hehehhehe

6. Kinda the same as 4

7-8. WTH ARE YOUR TEACHERS GIVING YOU O.O ?!!!!

9. FOE is the same as the one given The other one so what you do is 64+64 = whatever and divide that whatever by 2 and thats your answer

11. 180-118

12. Okay it was fun helping you but uh SHEESH some of the questions make my head hurt

Answer:

Step-by-step explanation:

From the figure attached,

ABCD is a square with vertices as,

A(-2, 0), B(-2, 2), C(0, 2) and D(0, 0)

If the given square is dilated by a scale factor of 2 and the center of dilation is the point D (origin).

Rule for the dilation of a point by a scale factor k is,

(x, y) → (kx, ky)

By this rule,

A(-2, 0) → A'(-4, 0)

B(-2, 2) → B'(-4, 4)

C(0, 2) → C'(0, 4)

D(0, 0) → D'(0, 0)

Now we can plot these points to get the image square (dilated figure) as given the figure attached.

Answer:

  a.  0.81

  b.  v = 28000(0.81^n)

  c.  2757.36

Step-by-step explanation:

a. The growth factor is 1 more than the growth rate. Here, the growth rate is -19% (per year), so the growth factor, the multiplier, is ...

  1 -0.19 = 0.81

__

b. The equation sets value equal to the original value multiplied by the growth factor to the power of the number of years:

  value = (original value) × (growth factor)^n

  v = 28000(0.81^n)

__

c. For n=11, this is ...

  v = 28000(0.81^11) ≈ 2757.36

The value of the truck after 11 years is about $2757.

Answer:

the answer to graph one is 1 and the second one answer is 2

Step-by-step explanation:

the other guy made it a hassle for no reason

The graph shown in figure 1 is a function, and the graph shown in figure 2 is not a function

Graphs are the visual way of representing functions and equations

For a graph to represent a function, then the graph of the function must pass the vertical line test

Graph 1 will pass the vertical line test, while graph 2 will not

Hence, the graph shown in figure 1 is a function, and the graph shown in figure 2 is not a function

Answer:

Step-by-step explanation:

use ratio of sides

x/10-x  = 2/3

cross multiply

3x = 2(10-x)

3x = 20 - 2x (add 2x to both sides of the equation)

Answer:

C

Step-by-step explanation:

The explicit formula is aₙ = -6 · 2⁽ⁿ⁻¹⁾, and we want to find the 9th term in the sequence. To find it, we can simply substitute n = 9 into the explicit formula, which gives us:

a₉ = -6 · 2⁽⁹⁻¹⁾

= -6 · 2⁸

= -6 · 256

= -1536

12/2

6

Answer:

The answer is 6.

Step-by-step explanation:

SInce x = 1/2, we multiply 8 by 1/2 which is 4.

y = 4, so 2 x 4 = 8. 8 + 4 = 12.

we divide by z, which is 2, so 12 ÷ 2 = 6.
