Answer:
B) -1/2
Step-by-step explanation:
(2, 3) and (4, 2)
Slope:
m=(y2-y1)/(x2-x1)
m=(2-3)/(4-2)
m= (-1)/2
m= -1/2
The Slope of the given line is -1/2.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
We take two points from the graph as (2, 3) and (4, 2).
Now, the slope of line is
= (3-2)/ (4-2)
= -1 / 2
= -0.5
Using Slope intercept form
y= mx+ b
y= -0.5x+ b
and, b = 4
so, the Equation of line is y= -0.5x+ 4.

find the length of the missing side in the following examples
Answer: 1. 6.1
2. 13
3. 5.4
4. 5.7
5. 10.4
6. 31
Step-by-step explanation:
I got the values of the missing sides by doing the Pythagorean theoreom. Therefore, I had to find the length of the hypotenuse. a^2+b^2=c^2
a and b are the values of the sides given, and we have to find the value of c. So, for instance on number one 6 and 3 are a b. (6)^2+(3)^2= 45. Now we have to find the square root of 45. The square root of 45 is 6.7082039325.
So the value of the missing side in number one is 6.7.

Regina Falange is 173 cm tall, making her line of sight exactly 163 from the ground. She is looking at a hawk in a tree and both are on level ground. The trunk of the tree is 10 meters away from her location and the angle of elevation from her eyeline to the hawk is 30 degrees. What is the hawk’s height above the ground?
a. Drawn a diagram that outlines the situation. Be sure to label the tree, hawk, Regina, the angle, etc.
b. Find the height of the hawk above the ground in cm. (Hint: Remember Regina’s height.) Round to the nearest hundredth.
Answer: 7.40 meters
Step-by-step explanation:
I went with 163 cm for the height because it says her eyeline is at 163 cm. I don't assume she would be looking from the top of her head so I went with that over 173 cm(h for hawk)
All you do is:
tan(30)=opposite/adjacent
tan(30)=h/10
10*tan(30)=h
h≈5.77 meters
163cm converted to meters is 1.63 meters, so add it to 5.77 and you will get 7.40 meters

Solve the system of equations

Answer:
y = 9.54
and, x = 0.08
Step-by-step explanation:
Given that
x - 2y = -19 .......................(1)
3x + 5y = 48 ...............(2)
Based on the above information
Multiply by 3 in equation 1
So,
3x - 6y = -57
3x + 5y = 48
- - -
-11y = -105
y = 9.54
So, the x would be
x - 2(9.54) = -19
x - 19.08 = -19
x = -19 + 19.08
x = 0.08

Please show work step by step
Step-by-step explanation:
It seems here that they are asking us to solve for x
to do this we first need to factor
Since we can't factor this using the normal method we can instead do this
x^2 -4x-17=0
add 4 to both sides as it is a perfect square
x^2 - 4x + 4 = 17 +4
(x-2)^2 = sqrt 21
x-2 = ± 4.58
x -2 = 4.58 x-2 = -4.58
x= 6.58 x=-2.58
Or just say x=2+√21 or x=2−√21

calculate the coefficient b in the function f (x) = - x + b for which it holds that the graph passes through the point (-1,3)
Need if fast!
Answer:
b = 2
Step-by-step explanation:
For the graph to pass through the point, we have it that the coordinates of the point will work in the equation of the line
Hence, by substituting the x value, we can get the y value and by substituting the y value, we can get the x value
where f(x) is same as y in this case
Thus, we have it that;
3 = -(-1) + b
3 = 1 + b
b = 3-1
b = 2

A 12-foot ladder leans against a building and makes an angle of 65 degrees with the ground. To the nearest foot, how far from the building is the base of the ladder?
Answer:
The foot of the ladder is 10 feet away from the base of the wall.
Step-by-step explanation:
Here , the wall , top and foot of the ladder and ground makes a right triangle of which length of ladder
h = 20 is regarded as hypotenuse, angle with ground is θ = 60 ;cos θ = b/h or cos 60 = b/20 or b = 20*cos 60 = 20* 1/2 = 10 feet.

find the x and y intercepts of the graph -6x + 4y = 32 state your answers as while numbers or as improper fractions in simplest form
Answer:
x intercept = -5.33
y intercept = 8
Step-by-step explanation:
The given equation is ,
⇒ -6x + 4y = 32 ,
The standard form of the Intercept form is ,
⇒ x/a + y/b = 1 , where
a is x interceptb is y intercept .• Converting the equation :-
⇒ 2( -3x + 2y ) = 32
⇒ -3x + 2y = 16
⇒ -3x + 2y / 16 = 1
⇒ (-3x)/16 + 2y/16 = 1
⇒ -3x/16 + y/8 = 1
Convert -3x/16 in x/a form⇒ x/-5.33 + y/8 = 1 .
Therefore ,
x intercept = -5.33 y intercept = 8Solve the simultaneous equations

Evaluate the piecewise function for the given values of x by
matching the domain values to the range values.
Answer:
For x = -4f (x) = x + 2
We evaluate the value of x = -4
f (-4) = (-4) + 2
f (-4) = -2
Answer is : f (-4) = -2For x = 4f (x) = -2x + 4
We evaluate the value of x = 4
f (4) = -2 (4) +4
f (4) = -8 + 4
f (4) = -4
Answer is : f (4) = -4For x = 0f (x) = 3x -4
We evaluate the value of x = 0
f (0) = 3 (0) -4
f (0) = 0-4
f (0) = -4
Answer is : f (0) = -4The value of the function at x = 1 is, f(x) = - x - 4 which equals f(1) = - 3.
What is an absolute value function?We know the absolute value function of the modulus function always outputs a positive value irrespective of the sign of the input.
In piecewise terms | x | = x for x ≥ 0 and | x | = - x for x < 0.
Similarly, A piecewise function can also be in terms of without modulus.
Given, f(x) = - x - 4 for x < 3.
f(x) = x² - 7, for 3 ≤x < 12.
f(x) = (120/x) + 5, for x ≥ 12.
Now, At x = 1, It satisfies,
f(x) = - x - 4 for x < 3.
Therefore, f(1) = - (-1) - 4.
f(1) = - 3.

Answer:
Step-by-step explanation:
I will focus on your function y = -x - 6.
First of all, this is a linear function. All linear functions have unlimited domain and range: (negative infinity, positive infinity).
If you meant (1/4)y = - x - 6, exactly the same response would be true.
