can someone explain the steps i need to do to complete this?

Answer:

x= 13/2

Step-by-step explanation:

multiply   4x4+4x3-9x2-x+2=x-1

calculate   16+12-18-x+2=x-1

move the terms   12-x=x-1

collect like terms calculate   -x-x=-1-12

divide both sides   -2x=-13

solution   x=13/2

im doing this problem right now---

ok so a1=256 a2=64 a3=15 a4=4... find a9

the sequence divides by 1/4 every term

an=a1*r^n-1

an=(256)*(1/4)^n-1

replace n with 9

A9=(256)*(1/4)^9-1

A9=(256)*(1/4)^8

=(256)*(1/4)

A9=64^8

1/256 or a9= 0.00390625

Answer:

202

Step-by-step explanation:

So it has to end in 2 because 20t+22 will always be a 2.

day1:

17x1+49=66

no 2

day2:

17x2+49=83

odd

day3:

D=100

no 2

day4:

odd

day5:

D=134

no 2

etc

keep adding 17 to D until you get one that ends in 2

D=202

A=202

Answer:

Step-by-step explanation:

The inflation is when prices for most of the goods increase with much less income raise.

Closest answer choice is C, provided it was followed up by price increase of most goods.

-x + 2y = 6

x=− 6+2y

4y - 2x = 11

4y-2(-6+2y)=11

4y+12-4y=11

12=11

no solution

But the diamerter equals d, so 6.

Answer:

The equation is ;

4x - y = 13

Step-by-step explanation:

The general equation of a straight line is;

y = mx + b

where m is the slope and b is the y-intercept

from what we are given, let us write the second equation in the general form

x + 4y = 10

4y = -x + 20

y = -1/4x + 20/4

y = -1/4x + 5

mathematically, when two lines are perpendicular, the product of their slope is -1

So for the second line with slope m2

m2 * -1/4 = -1

m2 = 4

So, using the general form, we have the equation as;

y = 4x + b

To get the value of b, we substitute the coordinates of the given point (3,-1)

-1 = 4(3) + b

-1 = 12 + b

b = -1-12

b = -13

So the equation is;

y = 4x - 13 which can be rewritten as;

4x-y = 13

Answer:

382 inches

Step-by-step explanation:

Given that :

The size of the soccer ball that Adrian and Violetta got is = 4

The diameter of the soccer ball is = 9 inches

Therefore, the radius of the soccer ball is, r = [tex]$\frac{9}{2}$[/tex]  inches

So the volume of the soccer ball is :

[tex]V = \frac{4}{3} \pi r^3[/tex]

[tex]V = \frac{4}{3} \times \frac{22}{7} \times \left(\frac{9}{2}\right)^3[/tex]

[tex]V = \frac{4}{3} \times \frac{22}{7} \times \frac{9}{2} \times \frac{9}{2} \times \frac{9}{2}[/tex]

V ≈ 382 inches

Answer:

  H  f(x) = -0.5(x -3)² +2

Step-by-step explanation:

The quadratic opens downward, so the leading coefficient is negative. All answer choices agree on this.

The vertex (maximum point) is (3, 2). Choices F and H are written in vertex form. Choice F has a vertex of (3, 8); choice H has a vertex of (3, 2), so is a likely candidate.

When we look at the graph 1 unit right or left of the vertex, we see that it is about 1.5, that is, 0.5 units below the vertex. This 0.5 is the magnitude of the leading coefficient, which we already know is negative. The leading coefficient of -0.5 eliminates choices F and G.

So, choice H has the correct leading coefficient and the correct vertex.

Choice J can be eliminated by looking at the value for x=0. For J, it is -6, but we see the y-intercept of the graph is -2.5. This eliminates choice J.

The only viable choice is H.

Answer:

Median without outlier should be 40

For the bottom questions, it should go:

Decreases the mean, does not change the median, does not change the mode

It's decreasing the mean because it goes from 44.7 to 39

Median w/ and without outlier is both 40

Mode also stays the same w/ or without the outlier, which is 96

Answer:

Your slope is 1

Step-by-step explanation:

This is because you go up two boxes and to the right two boxes but then you have to simplify giving you a slope of 1

Answer:

258 miles

Step-by-step explanation:

y = # miles truck driven

m = each mile driven

y = 14.95 + 0.97m

265.21 = 14.95 + 0.97m

250.26 = 0.97m

m = 258

Q1 = 61

Q3 = 63

Step-by-step explanation:

From the plot attached :

Data obtained is :

Temperature frequency

59 0

60 2

61 3

62 3

63 4

64 2

65 1

Frequency Total 15

Data in raw format :

60,60,61,61,61,62,62,62,63,63,63,63,64,64,65

The first quartile :

Q1 = 1/4(n+1)th term

n = 15

Q1 = 1/4(15+1)th term

Q1 = 1/4 * 16th

Q1 = 4th term

Q1 = 61

Third quartile (Q3):

Q3 = 3/4(n+1)th term

n = 15

Q3 = 3/4(15+1)th term

Q3 = 3/4 * 16th

Q3 = (48/4)th term

Q3 = 12th term

Q3 = 63

Answer:

Q1 is 61 and Q3=63

Answer:

Option A

Step-by-step explanation:

The standard form of an equation of a circle is represented by the formula [tex](x-h)^2+(y-k)^2 = r^2[/tex]. Remember that [tex](h,k)[/tex] is the center and [tex]r^2[/tex] is the radius squared.

So, the equation of the circle must be [tex](x+1)^2 +(y-4)^2 = 20[/tex]. Complete the square to change the form of the equations listed in the options and find the one that is equal.

Let's try this with option A. Move the constants to the right side, then use the completing the square method to place the equation in standard form:

[tex]x^2 + y^2 +2x -8y -3 = 0\\x^2 + y^2 +2x-8y = 3\\x^2 + 2x +y^2-8y = 3\\(x^2 +2x+1)+(y^2-8y +16)=3+1+16\\(x+1)^2 + (y-4)^2=20[/tex]

The end result matches with the equation determined before, so option A is the answer.

Answer:

Exceeded by 145 dollars.

Step-by-step explanation:

First you multiply 15 by 43 because each pot costs 15 dollars and they sold 45.

Then you get the answer of 645 and the goal was 500 so that means you need to subtract to see how much they exceeded by.

Subtract 500 from 645 and you get the answer of 145.

So they exceeded 145 dollars.
