Answer:

Geometric

Step-by-step explanation:

That is a geometric sequence, because the each number divided into 3. As we know if the pattern are multiply or divided it will be geometric, if it is sum or subtract will be arithmetic.

hope this helps

if u have question let me know in comments

geometric, because the ratio is constant and equals $\dfrac{1}{3}$

Solve the following system of equations algebraically and check.<br><br> y=x^2+3x+4<br> y-x=7

FinnZ [79.3K]

Y=x^2+3x+4
y-x=7

x^2+3x+4-x=7
x^2+2x+4=7
(factor) x^2+2x-3=0
(x+3)(x-1)=0
X= -3 and X=1
(Plug x in for y)
Y= 1^2+3(1)+4
Y=8
(Check your answer on the second equation)
8-1=7
7=7 (Which is the solution)

Pls help me, if you get it right I will give you Brainlist!

Answer:

38.5

Step-by-step explanation:

The formula for the area of the circle is $\pi rx^{2} \\$ .

Since you have the diameter and you're told to use 3.14 as pi, all you need to do is to substitute.

The diameter is also 2 times the size of the radius so you divide 7 by 2.

So $(3.14)(3.5)^{2} = 38.5$

Mai uses Triangle A and says the slope of this line is `\frac{6}{4}.` Elena uses Triangle B and says no, the slope of this line

nikdorinn [45]

Answer:

I agree with both of them because they are both correct

Step-by-step explanation:

See attachment for complete question;

Slope (m) is calculated using the following formula:

$m = \frac{Rise}{Run}$

Where

$Rise = Vertical\ Distance$

$Run = Horizontal\ Distance$

From the attachment, we have the following:

Triangle A

$Rise = 6\ units$

$Run = 4\ units$

So:

$m = \frac{Rise}{Run}$

$m = \frac{6}{4}$

<em>In this case, Mai is correct:</em>

Triangle B

$Rise = 1.5\ units$

$Run = 1\ units$

So:

$m = \frac{Rise}{Run}$

$m = \frac{1.5}{1}$

$m = 1.5$

<em>In this case, Elena is also correct:</em>
