What is 4/p = 11/2 plz help :)
makkiz [27]
Cross multiply
4/p=11/2
(4)*(2)=11*p
8=11p
Flip the equation
11p=8
Divide both sides by 11
11p/11=8/11
p=8/11
hope this helps!

Write the point-slope form of the line that passes through (5,5) and is perpendicular to a line with a slope of 1/4 include all
amid [387]

<u>Answer:</u>

The point-slope form of the line that passes through (5,5) and is perpendicular to a line with a slope of \frac{1}{4} is 4x + y -25 = 0

<u>Solution:</u>

The point slope form of the line that passes through the points \left(x_{1} y_{1}\right) and perpendicular to the line with a slope of “m” is given as  

\bold{y-y_{1}=-\frac{1}{m}\left(x-x_{1}\right)} ---- eqn 1

Where “m” is the slope of the line. x_{1} \text { and } y_{1} are the points that passes through the line.

From question, given that slope “m” = \frac{1}{4}

Given that the line passes through the points (5,5).Hence we get

x_{1}=5 ; y_{1}=5

By substituting the values in eqn 1 , we get the point slope form of the line which is perpendicular to the line having slope \frac{1}{4}can be found out.

y - 5 = -4(x - 5)

y - 5 = -4x + 20

on simplifying the above equation, we get

y - 5 + 4x -20 = 0

4x + y - 25 = 0

hence the point slope form of given line is 4x + y - 25 = 0

What is the range of function f in the function f(x)= -(2)^x + 4
tangare [24]

Answer:

A. {y | -∞ < y < 4}

General Formulas and Concepts:

<u>Algebra I</u>

  • Range is the set of y-values that are outputted by function f(x)<u> </u>

Step-by-step explanation:

According to the graph, we can see that we have a horizontal asymptote at y = 4. Our y-values stretch from negative infinity to the horizontal asymptote.

∴ our answer would be A.

Will give brainly to answer this correctly
professor190 [17]

Answer:

D) 2x² + x - 10

Step-by-step explanation:

First, distribute the negative sign to all terms within the second parenthesis:

- (4x - x² + 6) = -4x + x² - 6

Next, combine like terms:

5x + x² - 4 - 4x + x² - 6

(x² + x²) + (5x - 4x) + (-4 - 6)

2x² + x - 10

2x² + x - 10 , or D) is your answer.
