Answer:
y= -5x + 21
Step-by-step explanation:
The equation of the line that passes through (5, -4) and is perpendicular to line y = 1/5x + 4 is y= -5x + 21
The slope that is perpendicular to the slope 1/5x is -5x.
To find a perpendicular slope, you take the negative reciprocal. (so you change the signs (1/5x is positive so now it would be negative) and -5/1 is basically -5)
However, y = -5x + 4 does NOT pass through (5, -4)
But we still have to write the equation in slope intercept form or the equation of the line
The formula for slope- intercept form is : y= mx + b
So we must plug in (m) which is our -5x and for y we look at the coordinates they gave us ----- (5, -4). -4 is our y. In the coordinates we also have x listed which is 5, so we all plug that in.
y = -5x + b (as you can see -5x is plugged in here)
-4 = -5x + b (as you can see -4 is plugged in here)
4 = -5(5) + b (as you can see 5 is plugged in here)
NOW WE MUST SOLVE!
Isolate B
-4 = -25 + b
Add 25 from both sides.
-4 = -25 + b
+25 25
----------------
21 = b
We can now plug this into our slope intercept formula---y= mx+ b---to find the equation of the line.
Therefore, y = -5 x +21

What is the approximate length of a diagonal of a square with a perimeter of 48 inches?
Answer:
diagonal length = 12√2 inches
Step-by-step explanation:
If the perimeter of the square is 48 inches, the length of one side is one fourth of that, or 12 inches. The diagonal creates a 45-45-90 triangle with two 12-in legs; we are to find the length of the diagonal. Using the Pythagorean Theorem, we get
12² + 12² = (diagonal length)², or 2(12²) = (diagonal length)²
Taking the square root of both sides, we get:
diagonal length = 12√2 inches

d=-7.6+4.2
d=-3.4
Answer:
Seems like it'll be 11.8
Step-by-step explanation: Since the answer is 7.6 I just thought what subtract 4 equal 11 and 7 came to mind which gives me the 11. then 2-8=6
that's how i got 11.8 or an simple way of doing it is adding 4.2 + 7.6 and you'l; still get 11.8

Find the measure of the indicated arc
Step-by-step explanation:
We know that if an arc subtends an angle of theta , with a radius r , then the measure of arc is r× theta . Here theta is 109° .
[tex]\implies l = r\theta \\\\\implies l = r\times 109^{\circ}\\\\\implies l = r \times \dfrac{109}{180}\pi rad \\\\\implies \boxed{\boxed{ l = 0.6\pi r m }}[/tex]
where r will be the radius .
-1/4a - 4 =4
what does a =
Answer:
a = -32
Step-by-step explanation:
-1/4a - 4 =4
Add 4 to each side
-1/4a - 4+4 =4+4
-1/4a = 8
Multiply each side by -4 to isolate a
-1/4 a * -4 = 8 *-4
a = -32

Sharif drove 295 miles from St. Louis to Detroit at an
average speed of 65 mph. Which equation can be
used to find the time of the trip (x) in hours?
You did not provide a list of equations for us to select from.
Let me see if I can put together.
Distance = rate times time (in hours).
Let x = time of the trip in hours.
D = rx
Let D = 295 miles.
Let r = 65 mph.
Here is your equation: 295 = 65x

If you vertically compress the absolute value parent function, f(x) = [X1, by a
factor of 5, what is the equation of the new function?
O A g(x) = [x - 51
B. g(x) = 1x1
C. g(x) = 5|X1
D. g(x) = (5x1
Answer:
your answer should be C.
Step-by-step explanation:
brainliest?
The transformation of the parent function f ( x ) = | x | by a compression of 5 units is given by g ( x ) = ( 1/5 ) | x |
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)
Right shift by c units: y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given data ,
Let the parent function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = | x | be equation (1)
On simplifying , we get
when the function is stretched vertically by a factor , we get
Vertical stretch by a factor k: y = k × f(x)
And , when it is compressed by a factor of k = 5 units
The transformed function is g ( x ) = ( 1/5 ) | x |
Hence , the transformed function is g ( x ) = ( 1/5 ) | x |
