Which equation has the least steep graph?

Mathematics
2 answers:
marshall27 [118]3 years ago

Y = 1/4x + 6.....this has a slope of 1/4 (or 0.25).....| 0.25 | = 0.25
y = -3/4x - 9....this has a slope of -3/4 (or - 0.75)...|-0.75 | = 0.75
y = 2x + 1.......this has a slope of 2...| 2 | = 2
y = -7x - 2......this has a slope of -7...| -7 | = 7

to find the least steep, take the lowest number of the absolute value of the slopes.

so the least steep graph is gonna be A. y = 1/4x + 6

Will give brainliest answer What is the value of a21? A.36 B. 58 C.60 D. 41
Strike441 [17]

Answer:

41

Step-by-step explanation:

Matrix Multiplication follows a row-column format. In order to compute this, you must be familiar with vector dot products.

With that in mind, lets get straight into it.

The order that matrix multiplication follows means that the terms in the result are filled in left to right, then top to bottom.

Therefore, a21 will be the 3 value that is computed. This is important becuase this allows to directly compute a21, instead of using up a lot of time computing all the values before.

As a21 is located in the bottom row 1st column, we take the dot product of the 2nd row in matrix 1 and the 1 column in matrix two.

So we have:

(7 2) dot (5 3) = 7*5 + 2*3 = 41

Which function has an inverse function?
daser333 [38]

Answer: Option B

Step-by-step explanation:

By definition, only those functions that are one to one have an inverse function.

A function is one by one if there are not two different input values, x_1 and x_2, that have the same output value y

Note that the function f(x)= \frac{|x+3|}{5}  is not a one-to-one function

When x=2  f(x)= \frac{|2+3|}{5}=1\ ,\ \ y=1

When x=8  f(x)= \frac{|-8+3|}{5}=1\ \ ,\ y=1

Note that the function f(x)= \frac{x^4}{7}+ 27  is not a one-to-one function

When x=1 f(x)= \frac{(1)^4}{7}+27\ ,\ \ y=\frac{190}{7}

When x=-1  f(x)= \frac{(-1)^4}{7}+27\ ,\ \ y=\frac{190}{7}

Note that the function f(x)= \frac{1}{x^2}  is not a one-to-one function

When x=1 f(x)= \frac{1}{(1)^2}\ ,\ \ y=1

When x=-1  f(x)= \frac{1}{(-1)^2}\ ,\ \ y=1

Then the answer is the option B.

You can verify that The function f (x) = x ^ 5-3 is a one-to-one function and therefore its inverse is a function

Find a value of x that makes the equation true:<br> -(-2x + 1) = 9 – 14x
luda_lava [24]

Answer:

x=0.625

Step-by-step explanation:

-(-2x+1)=9-14x

distribute:

2x-1=9-14x

add  1 to both sides

2x = 10-14x

add 14x to both sides

16x=10

divide by 16 to isolate x

x = 0.625

check:

-(-2(0.625)+1) = 9-14(0.625)

0.25 = 0.25

I need help with the first two
mel-nik [20]
The work and answer provided are correct, the simpler way of doing it is

1)
1/6 page written in 1/12 of a minute
to write a full page, you would need to write 1/6, 6 times
so,
\frac{1}{6} \time 6 = 1
and
\frac{1}{12} \times 6 = \frac{6}{12} = \frac{1}{2}

so it takes 1/2 of a minute to write a full page, there are 60 seconds in a minute, 1/2 of 60 seconds is 30 seconds

same process works for question 2(use 3 instead of 6 though)
