➷ You have to collect like terms

In other words, add together the values that have x in them and add together the values that don't

4x + 7x = 11x

8 + 3 = 11

The answer is 11x + 11

For the function given, state the middle line; f(t) = 40cos (80t + 20)

Digiron [165]

In the standard form of the equation

$\\ \ f(t)=Acos[b(t\pm c)]+k\\ \\$

The middle line =k

For our given problem

f(t) = 40cos (80t + 20)

On comparison we get k=0

Hence middle line=0

Question on the photo

IrinaVladis [17]

Answer:

Step-by-step explanation:

Since it is only addition and subtraction, you can rearrange the order of the equations. This is what the three eqautions will look like after the arrangement:

1.6z + 8.3 z = ? (9.9z)

6.2y - 5.1y = ? (1.1y)

4.3x + 5.5x = ? (9.8x)

Then you just add and subtract.

Which line represents the linear equation

zzz [600]

Answer:

Pat a) The graph in the attached figure

Part b) $y=(4/3)x-5$

The slope is $m=(4/3)$

The y-coordinate of the y-intercept is $b=-5$

Step-by-step explanation:

Part a) Which line represents the linear equation $-3y=15-4x$ ?

To graph the linear equation find the intercepts

we know that

The y-intercept is the value of y when the value of x is equal to zero

For x=0

$-3y=15-4(0)$

$-3y=15$

$y=-5$

The y-intercept is the point $(0,-5)$

The x-intercept is the value of x when the value of y is equal to zero

For y=0

$-3(0)=15-4x$

$4x=15$

$x=15/4=3.75$

The x-intercept is the point $(3.75,0)$

Plot the intercepts to graph the linear equation

see the attached figure

Part b) Rewritten in slope-intercept form

we know that

The equation of the line into slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-coordinate of the y-intercept

we have

$-3y=15-4x$

convert to slope intercept form

isolate the variable y

$3y=4x-15$

$y=(4/3)x-5$

The slope is $m=(4/3)$

The y-coordinate of the y-intercept is $b=-5$

It takes you 0.8 of a minute to read each page of your health book. it takes you 5.5 minutes to take the test at the end. how lo

o-na [289]

Answer: 10.5 minutes

Step-by-step explanation:

Given: Time taken to read each page of health book = 0.8 minutes

Time taken to take the test at the end = 5.5 minutes

Let x be the number of pages of book to read, then time taken to read pages and take the test is given by :-

$T(x)=0.8x+5.5$

If we read 6.25 pages, then time taken to read 6.25 pages and take the test is given by :-

$T(6.25)=0.8(6.25)+5.5=5+5.5=10.5\ minutes$
