∠1 and ∠4 are corresponding angles has the same shape and size. ∠1 and ∠3 are diagonal from each other and ∠15 and ∠9 make a straight line.

Parallel lines represent coplanar endless straight lines in geometry that never intersect. Within a single three-dimensional space, parallel planes are any planes that never cross. Curves with a predetermined minimum distance between them and no contact or intersection are said to be parallel.

Euclid's parallel postulate deals with parallel lines. Euclidean geometry is indeed a particular example of this sort of geometry, and parallelism is essentially a feature of affine geometries.

∠1 and ∠4 are corresponding angles has the same shape and size

∠1 and ∠3 are diagonal from each other

∠15 and ∠9 make a straight line

Therefore, ∠1 and ∠4 are corresponding angles has the same shape and size. ∠1 and ∠3 are diagonal from each other and ∠15 and ∠9 make a straight line.

Answer: B) Michiko is right for this system of linear equations, and her method will also work for other systems of linear equations

Hope this helped

Michiko is right for this system of linear equations, but her method will not work for other systems of linear equations, option A is correct.

Two or more expressions with an Equal sign is called as Equation.

To solve the system of linear equations 15x + 8y = 1 and 21x + 4y = -13, Michiko suggests multiplying the second equation by 2 and then subtracting the second equation from the first equation.

Multiplying the second equation by 2 gives:

42x + 8y = -26

Now, subtracting the second equation from the first equation gives:

15x + 8y - (42x + 8y) = 1 - (-26)

Simplifying this equation gives:

-27x = 27

Divide both sides by 27

x=-1

we can substitute x = -1 into either of the original equations.

Using the first equation, we get:

15(-1) + 8y = 1

Simplifying this equation gives:

8y = 16

Dividing both sides by 8 gives:

y = 2

Hence, Michiko is right for this system of linear equations, but her method will not work for other systems of linear equations, option A is correct.

Answer:

Mother = 17 inches and then Newborn = 5 (2/3) or 5.66666666667 inches

Step-by-step explanation:

I was sort of guessing based on your question what you were looking for. How I solved this is we know that since the average adult giraffe is 18 feet tall and the average newborn giraffe is 6 feet tall, then the adult giraffe is about 3 times as tall as the average newborn giraffe so the ratio is 3:1 adult: newborn. So with the mother at 17 inches, then since the newborn giraffe is, on average, 3 times smaller than the mother, it is therefore 17/3 = 5.666667 or 5 and 2/3s.

Median is the middle of the data points.

Line data points up in order from least to greatest.

29,30,30,30,30,31,31,31,31,31,31,31

12/2=6

Since there is an even amount data points the median is the mean of the two middle data points:

Middle data points: 31,31

31

Answer: The answer to the equation 4,240/8 = 530

Step-by-step explanation:

4,240 divided by 8 = 530

4,000 divided by 8 = 500

4,800 divided by 8 = 600

(For part B 500 would be an underestimate of the answer to 4,240/8 and 600 would be an overestimate of 4,240/8)

A rate of change formula is used to calculate the rate which describes how one quantity changes in relation to the change in another quantity

Answer:

y = -5x - 3

Step-by-step explanation:

To answer this the slope must be clculated first

slope equation:

[tex]\frac{y2-y1}{x2-x1}[/tex]

these variables symbolize ordered pairs, and the best part is that you can use any two ordered pairs for this example we can use (-5, 10) and (-3,0)

we'll call the first ordered pair 1 so x1 = -5 and y1 = 10.

the next odered pair is 2 so x2 = -3 and y2 = 0.

With this information layed out we can solve:

[tex]\frac{0-10}{-3-(-5)}[/tex]

0 - 10 = -10

-3 - (-5) = 2 --- remember negatives cancel each other out to make a positive

[tex]\frac{-10}{2}[/tex] = -5

the slope of the line is -5. Now the next thing to note is that one of the ordered pair (-3,0) is a y intercept. It's time to introduce the equatione of a line:

y = mx+b

There are other equations that can be used for a line but with the info given this equation best suits the data.

m = slope

y and x = are the ordered pair you can input into the equation to slove

b = the y intercept

So the equation would be:

y = -5x - 3

Answer:

The values that are in the correct spots are: 82, 62, 163 and 300

Step-by-step explanation:

There are 144 boys in total. We know that 82 attended the fall fling, so if we do 144-82 we know that 62 boys attended the spring social, therefore the vaules 82 and 62 are in the correct spots. We know that out of 156 girls, 75 attended the spring social. 156-75=81. The values 75 and 81 are in the wrong spots, therefore they are not correct.

82 boys + 81 girls at the fall fling = 163 total students at the fall fling, therefore 163 is also in the correct spot.

62 boys + 81 girls at the spring social = a total of 137. The chart says the total is 143 which is incorrect.

156 total boys plus 144 total girls = 300 total students, therefore 300 is in the correct spot.
