Which is an irrational number?

HELP PLEASE

Step-by-step explanation:

(3x+3)(x+2)=

3x^2+6x+3x+6

=3x^2+9x+6

we get quadratic equation

find discriminant:

D=b^2-4ac=81-72=9

x=(-b±√D)/2a

x1=-6/6=-1

x2=-12/6=-2

one of the x values should be correct.

but why when I try to put values I get zero

Answer:

2(6a+5)

Step-by-step explanation:

Factor 12a+10

12a+10

=2(6a+5)

Answer:

2(6a+5)

Step-by-step explanation:

Answer:

Step-by-step explanation:

CA and CB are perpendicular to OA and OB, so the angles A and B are right angles.

Angles AOB and ACB sum to 180°

Correct option is 2) 44°

Answer:

angle 11 they are vertically opposite.

∠11 must also be 85 degrees.

Angles that are vertically opposed to one another at a certain vertex are formed by two straight lines intersecting. Angles that are vertically opposed to one another are equal. They are referred to as vertical angles at times.

As per the given data:

∠9 = 85°

From the diagram, ∠9 and ∠11 are vertically opposite angles.

∴ ∠9 = ∠11

∠11 must also measure 85°.

Answer:

13 team members are included in the​ histogram.

Step-by-step explanation:

Consider the provided information.

The required histogram is shown in the figure.

We need to find the team members included in the histogram.

For this, we will add the frequency or the height of each bar.

2+1+1+5+1+3=13

Hence, 13 team members are included in the​ histogram.

Answer:

A. 5.8

Step-by-step explanation:

if ABCD was reflected to FGHI means that A became F and B became G so AB became (was mapped to ) FG after reflection.

the length ( or distance) after reflection is is preserved ( does not change) so

if AB = 5.8 units then FG =5.8 units.

Answer: f(x) = 3x + 10

Step-by-step explanation: Function notation uses the terms "f(x)." It's the same thing as y.

This is is the correct function notation:

Step-by-step explanation:

the semi circle

Answer:

y-intercept:  -18

x-intercept: 9/4

Step-by-step explanation:

Substitute x = 0, we find that y = -18 i.e. the y-intercept is -18.

Substitute y = 0, we find that x = 9/4 i.e. the x-intercept is 9/4.

Answer:

The line test is the third graph that shows a vertical line with two points plotted.

Step-by-step explanation:

A line test is used to determine if a graph is a function. Every input should only have one output. Since when she inputs 1.5 she gets two different answers it is not a function.

Answer:

The equation in slope-intercept form perpendicular to the given equation [tex]y = -3x + 4[/tex] through the given point (6,-2) is [tex]\mathbf{y=\frac{1}{3}x}[/tex]

Step-by-step explanation:

We need to write an equation in slope-intercept form perpendicular to the given equation through the given point

y = -3x + 4

(6,-2)

The general equation in slope intercept form is: [tex]y=mx+b[/tex] where m is slope and b is y-intercept.

We need to find slope and y-intercept.

Finding slope:

The given line is perpendicular to required line, so there slopes are opposite

The slope of given line [tex]y = -3x + 4[/tex] is m = -3, (By comparing it with general equation y=mx+b, we get m = -3)

The slope of required line is: [tex]m = \frac{1}{3}[/tex]

Finding y-intercept:

y-intercept can be found by using slope [tex]m = \frac{1}{3}[/tex] and the point(6,-2)

[tex]y=mx+b\\-2=\frac{1}{3}(-6)+b\\-2=-2+b\\b=-2+2\\b=0[/tex]

So, we get y-intercept b =0

Equation of required line:

So, the equation of required line having slope [tex]m = \frac{1}{3}[/tex] and y-intercept b =0 is:

[tex]y=mx+b\\y=\frac{1}{3}x+0\\y=\frac{1}{3}x[/tex]

So, the equation in slope-intercept form perpendicular to the given equation [tex]y = -3x + 4[/tex] through the given point (6,-2) is [tex]\mathbf{y=\frac{1}{3}x}[/tex]

Answer:

5

Step-by-step explanation:

Slope intercept form is where y= mx + B where M is the slope and B is the y-intercept

Answer:

e=-1/2

Step-by-step explanation:

4/3=-6e-5/3

Multiply both sides by 3:

4=-18e-5

Add 18e to both sides:

18e+4=-5

Subtract 4 from both sides:

18e=-9

Divide both sides by 18:

e=-1/2

Answer:

The answer could be anything, but if it's an arithmetical sequence, then it's 14.

Step-by-step explanation:

I'm assuming that the added numbers always stay the same, meaning it's linear. If you add 5 to 9, you get 14. If you add 5 again, you get 19. Another way of doing this is (19-9)/2 = 5, then 9+5=14.

Answer:

20.5%

Step-by-step explanation:

Here, we want to calculate the % spent on Jewelry

To get that, we divide the amount spent on Jewelry by the total budget and multiply by 100

That will be;

61.5/300 * 100% = 20.5%
