Which of the following theorems verifies that DEF = STU
As we look at both triangles, we can see that they have a few things in common.
Each triangle shares a right angle, one leg, and an acute angle.
LL = leg and leg
HA = hypotenuse and angle
HL = hypotenuse and leg
LA = leg and angle
The triangles do not share two legs, nor do they share a hypotenuse.
Therefore,
LA is the only choice that makes sense.
For these two right triangle, LA(Leg and angle) verifies that ΔDEF ≅ ΔSTU.
What is the condition of congruence of two right triangles?If the hypotenuse and a side of a right- angled triangle is equivalent to the hypotenuse and a side of the second right- angled triangle, then the two right triangles are said to be congruent.
In these two given right triangles, ∠D = ∠S and ∠F = ∠U.
Therefore, the third angle of each triangle are equal as per the third angle theorem.
The leg of each triangle is equal as mentioned.
Therefore, LA(Leg and angle) verifies that ΔDEF ≅ ΔSTU.

4. Explain how to graph the equation y = -2x + 3 *
Answer:
Step-by-step explanation:
Easy way: type the equation into a graphing calculator.
__
By hand: find a couple of points and draw a line through them.
The equation is in "slope-intercept" form:
y = mx + b
where m is the slope (-2) and b is the y-intercept (3). The y-intercept is where the line crosses the y-axis, so right away you know one point on the line. That point is (0, 3).
The slope of -2 means for each horizontal unit, the line drops 2 units vertically. The point 1 unit to the right of (0, 3) is (1, 3); and the point 2 units below that is (1, 3-2) = (1, 1). So, another point on the line is (1, 1).
You can plot those two points and draw the line through them.

Compare your response to the sample response above. What did you include in your explanation? a reference to the horizontal-line test a statement that the function is one-to-one the conclusion that the inverse is a function
Answer:
all of the answers are correct
Step-by-step explanation:
i took the test and got a hundred! it's a trick question
The statements included in the explanation on the horizontal line test are follows as a reference to the horizontal-line test, a statement that the function is one-to-one. and inverse is a function.
What is the horizontal-line test?The horizontal line test is used to not only find out if a graph has an inverse function, but also if that inverse is also a function itself.
In order to pass the horizontal line test, the function has to be one-to-one which means that a horizontal line can intersect the graphed function at one point in all places.
If this happens, then there is an inverse and the inverse itself is a function.

If the graph passes the horizontal-line test, then the function is one-to-one. Functions that are one-to-one have inverses that are also functions. Therefore, the inverse is a function. Compare your response to the sample response above.
is 2.7 a rational or a irrational
Answer:
Rational
Step-by-step explanation:
2.7 can be written as a fraction, so therefore it is ration[tex]2.7=2\frac{7}{10} =\frac{27}{10}[/tex]al.
The number 2.7 is a rational number.
A rational number is a number that can be expressed as a ratio of two integers, where the denominator is not zero.
In other words, a rational number can be written in the form p/q, where p and q are integers, and q is not equal to zero.
Now, let's express 2.7 as a fraction:
2.7 = 27/10
Since 27 and 10 are both integers, and the denominator (10) is not zero, we have successfully expressed 2.7 as a fraction of two integers.
Therefore, 2.7 is a rational number.
On the other hand, an irrational number cannot be expressed as a simple fraction of two integers. Examples of irrational numbers include π (pi) and √2 (the square root of 2).
These numbers have non-repeating and non-terminating decimal expansions, and they cannot be written as a fraction of two integers.
However, 2.7 is a terminating decimal (it has a finite number of decimal places), and it can be expressed as a fraction, making it a rational number.

If rain is falling at 0.5 inches per hour and 1.5 inches have already accumulated, how many hours must have passed if there are 5 inches of rain? Create a linear equation that is a model for the rain that has accumulated. Select the two correct answers. (1 point)
Given :
Rain is falling at 0.5 inches per hour and 1.5 inches have already accumulated.
To Find :
How many hours must have passed if there are 5 inches of rain .
Solution :
Let , after x hours rain accumulated is 5 inches .
We know , general equation of line :
y = mx +c
Here , m = 0.5 and c = 1 .
So , equation of rain accumulated is :
[tex]y=0.5x+1[/tex]
Now , putting value of x = 5 hours .
We get :
[tex]y=0.5\times 5+1\\\\y=2.5+1=3.5\ inches[/tex]
Hence , this is the required solution .
Answer:
0.5h+1.5=5
1.5h+0.5=5

y= 2.83x + 88.7 i need the slope for this. can someone help? what is the relationship in the equation
Hey there! I'm happy to help!
This is slope intercept form: y=mx+b, where m is the slope and b is the y intercept. The slope is what is multiplying x. In our case, 2.83 is multiplying x, so 2.83 is the slope.
