Someone help me ASAP PLEASE

2nd term: 3(2)^2 - 1

5th term: 3(5)^2 - 1

Answer:

11 and 74

Step-by-step explanation:

To find the second and fifth terms substitute n = 2, n = 5 into the rule, that is

a₂ = 3(2)² - 1 = 3(4) - 1 = 12 - 1 = 11

a₅ = 3(5)² - 1 = 3(25) - 1 = 75 - 1 = 74

Answer:

3

Step-by-step explanation:

the equation is y=mx+b

m=slope

so then 3 would be the slope

hope this helps :3

if it did pls mark brainliest

Answer:

3

Step-by-step explanation:

To find the slope, think of the equation used for slope intercept form.

y = mx + b

m is the slope, and b is the y intercept.

In this equation, m = 3

Thus, the slope is 3

Answer:

0

Step-by-step explanation:

Answer:

The point is located in the fourth quadrant because x is positive and y is negative. The quadrants are labeled in counter-clockwise order, starting in the upper-right.

Step-by-step explanation:

Answer:

It would be located in the second quadrant or the one under the positive quadrant

Step-by-step explanation:

Answer:

c

Step-by-step explanation:

It is given that the line AB is Perpendicular Bisector of IK. It means the line AB is perpendicular on IK and the point J divides the line IK in two equal parts.

If a line is bisector of another line, then the point of intersection divides the second line is two equal parts.

Therefore the distance between intersection point and the endpoints of the second line are the same.

The intersection point is J and the end points of IK are I and K. So, we can say that IJ = JK.

uhm the last gurl was wrong pretty sure its 9 plain

Step-by-step explanation:

Answer:

y<2x−1

Step-by-step explanation:

1 Subtract 2x2x from both sides.

-y>1-2x−y>1−2x

2 Multiply both sides by -1−1.

y<-1+2xy<−1+2x

3 Regroup terms.

y<2x-1y<2x−1

resembling without being identical

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

to get x alone you divide the 2 away on both sides, getting x = 8. To check multiply 8 by 2 and you get 16.

Hope this helps!

Take the root of both sides and solve.

x = 4, −4

Answer:

y=40x+75

40 is the slope and the y-intercept is 75

Answer:

That is an 80% increase

Answer: that is a 45 degree angle

Step-by-step explanation: 90 / 2 is 45

Answer:

∠ A = 44°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

x + 59 + x + 51 + 84 = 180, simplify

2x + 194 = 180 ( subtract 194 from both sides )

2x = - 14 ( divide both sides by 2 )

x = - 7

Thus

∠ A = x + 51 = - 7 + 51 = 44°

Answer:

The x-intercept is  ( 4 , 0 ) .

The y-intercept is  ( 0, 6 ) .

Step-by-step explanation:

his is the formula for a linear equation in standard form. This is the easiest equation for finding the intercepts. To find the x- and y-intercepts, substitute  0  for one variable, and solve for the other.

X-intercept: value of  x  when  y = 0

Substitute  0  for  y  and solve for  x .  

3 x + 2 ( 0 ) = 12  

3 x = 12  

Divide both sides by  3 .

x = 12 /3

x = 4  

The x-intercept is  ( 4, 0 ) .

Y-intercept: value of  y  when  x= 0

Substitute  0  for  x  and solve for  y .

( 0 ) + 2 y = 12

2 y= 12

Divide both sides by  2 .

y = 12 /2  

y = 6

The y-intercept is  ( 0 , 6 ) .

These are the intercepts.

Answer:

The table shows an exponential function

Step-by-step explanation:

Linear vs Exponential Functions

A linear function is written as:

[tex]y=mx+b[/tex]

where m and b are constants.

If a table contains a linear function, then for each pair of ordered pairs (x1,y1) and (x2,y2), the value of m must be constant.

The slope can be calculated as:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

An exponential function is written as:

[tex]y=y_o.r^x[/tex]

Where r is the ratio and yo is a constant.

If a table contains an exponential function, for two ordered pairs (x1,y1) and (x2,y2), the value of r must be constant.

The ratio can be calculated as:

[tex]\displaystyle r=\sqrt[x2-x1]{\frac{y2}{y1}}[/tex]

Calculate the slope for (0,4) and (1,2):

[tex]\displaystyle m=\frac{2-4}{1-0}=-2[/tex]

Calculate the slope for (1,2) and (2,1):

[tex]\displaystyle m=\frac{1-2}{2-1}=-1[/tex]

Since the slope is not the same, the function is not linear.

Now calculate the ratio for (0,4) and (1,2)

[tex]\displaystyle r=\sqrt[1-0]{\frac{1}{2}}[/tex]

The radical of index 1 is simply equal to its argument:

[tex]\displaystyle r=\frac{1}{2}[/tex]

Now calculate the ratio for (0,4) and (2,1)

[tex]\displaystyle r=\sqrt[2-0]{\frac{1}{4}}[/tex]

[tex]\displaystyle r=\sqrt{\frac{1}{4}}[/tex]

[tex]\displaystyle r=\frac{1}{2}[/tex]

Testing other points we'll find the same ratio, thus the table is an exponential function

Answer:

true

Step-by-step explanation:

for example, when you solve an equation and you get something like 16=16, which is infinitely many solutions and is also a true statement

Answer:

32 orange marbles.

Step-by-step explanation:

First set up the proportion given in the problem, since it states that there are three red marbles for every four orange marbles. The ratio between them is 3:4.

This means that you can multiply the given amount of red marbles by 4/3 to find the amount of orange marbles and the given amount of orange marbles by 3/4 to find the amount of red marbles. Because there are 3 red marbles for every 4 orange marbles.

You can divide 32 by 3 to find the factor which is 8 and multiply by 4 to get 32. Because 8 × 3 = 24,

and 8 × 4 = 32.

It can also be thought of as fractions because the proportion is a factor which means that you can multiply and divide to get to a certain value.

So:

3/4 = 24/O

Red marbles / orange marbles = red marbles / orange marbles.

(cross multiply ; numerator times denominator, and denominator times numerator; numerator is the top number, and the denominator is bottom number of a fraction).

3O = 96

÷3 ÷3

O [orange marbles] = 32
