Answer:

1. im not really sure abt this one

2. 11x-16

3. 35+1/x+1

Step-by-step explanation:

2. x^2/x^2=x

3X--7X=10X

-28+12=-16

x+10x=11x

3. 5/1*6/1=35

35+1/x+1

A linear function has a slope of -7 /9 and a y-intercept of 3. How does this function compare to the linear function that is rep

ValentinkaMS [17]

Answer:

both functions have the same graph

Step-by-step explanation:

The first function is described in terms of its slope and y-intercept, so can be written in slope-intercept form as ...

y = mx + b . . . . m = slope (-7/9); b = y-intercept (3)

y = -7/9x +3

The second function is written in point-slope form:

y -k = m(x -h) . . . . m = slope (-7/9), point = (h, k) = (18, -11)

y +11 = -7/9(x -18)

If we rearrange the second equation to the form of the first, we get ...

y = -7/9x +14 -11 . . . . eliminate parentheses, subtract 11

y = -7/9x +3 . . . . . . . matches the equation of the first function

Both functions describe the same relation.

This is super hard i needd help

natta225 [31]

Answer:

2587mm^3 approx!

Step-by-step explanation:

first you divide the nut into 6 part(in triangle now, by joining centre to each edge)

let's take one part of the triangular shape then area of that part can be found by using 1/2×base×height

i.e, 1/2×13×15=97.5(mm^2)

now when we consider depth of that traingular part,we will get volume of that part as area×depth

i.e, 97.5×6=585(mm^3)

now volume of all the 6 triangular part is 585×6=3510(in mm^3)

now take circular cavity in consideration, it's volume will be π(7^2)6=923(mm^3) approximately

now reqired volume will be volume of that hexagonal part minus that of circular cavity

=3510-923

=2587mm^3

What’s the slope of this graph? Can y’all guys help please ! Thank y’all

Anvisha [2.4K]

Answer:

Step-by-step explanation:

we can think of the slope of a graph as $\frac{rise}{run}$

the "rise" is the difference in y-values between two points (the change in y)

the "run" is the difference in x-values between two points (the change in x)

when we divide these (rise/run), we find the slope

you can choose any two well-defined points (with clear x and y values), here are the two we will be using:

(remember, points are written as (x, y) )

(0 , 2)

(-1 , -1)

for the "rise", we have risen 3 (difference between 2 and -1 = 3 [2- -1 = 3] )

for the "run" we have ran 1 (difference between 0 and -1 = 1) (0 - - 1 = 1)

so, the slope for this graph is: 3/1 ; which simplifies to 3

So, the slope of our graph is 3

--------------------------------------------------------------

technical layout:

$m=\frac{y_{2} -y_{1}}{x_{2}-x_{1}}$ (note: slope is called "m" in the format of y=mx + b)

$y_{1}$ means one y-value, $y_{2}$ means other y-value

$x_{1}$ means one y-value, $x_{2}$ means other x-value

{note: it is important to keep the y1 and x1 from the same point, and the y2 and x2 from a shared point}

our equation in this layout:

$m=\frac{2 -(-1)}{0-(-1)}$ = $m=\frac{3}{1}$

m = 3

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. What is the output

Levart [38]

Answer:

When the input is 4, the output of f(x) = x + 21 is 25.

Step-by-step explanation:

The given function is

$f(x)=x+21$

Here, x is input and f(x) is output.

We need to find the output of the given function f(x) if the input is 4.

Substitute x=4 in the given function.

$f(4)=4+21$

$f(4)=25$

So, the output value is 25.

When the input is 4, the output of f(x) = x + 21 is 25.

How to solve frequency distribution problems

vova2212 [387]

Example 1 – Constructing a frequency distribution table

Divide the results (x) into intervals, and then count the number of results in each interval. ...

Make a table with separate columns for the interval numbers (the number of cars per household), the tallied results, and the frequency of results in each interval.
