Answer:

−2y+24

Step-by-step explanation:

Let's simplify step-by-step.

7y−4(9/4y−6)

Distribute:

=7y+(−4)(9/4y)+(−4)(−6)

=7y+−9y+24

Combine Like Terms:

=7y+−9y+24

=(7y+−9y)+(24)

=−2y+24

Answer:

Answer:

( 20 × 10 ) + ( 20 × 7 ) + ( 2 × 10 ) + ( 2 × 7 )

Step-by-step explanation:

To create partial products when multiplying two numbers, first break the numbers up into a sum of two numbers. The order that these numbers are multiplied does not necessarily matter as long as they are multiplied with the correct numbers.

22 × 17 = (20 + 2)(10 + 7) = 20 (10 + 7) + 2 (10 + 7) =

( 20 × 10 ) + ( 20 × 7 ) + ( 2 × 10 ) + ( 2 × 7 )

= 374

You can check this method works by using your calculator, and multiplying 22 by 17 to get 374 again!

Then just add like you would if when you distribute.

Remember FOIL (First, Outer, Inner, Last)

when multiplying two binomials(2 terms) or distributing factors with two terms.

For example:

(a + b)(c + d) =

F F

O O

I I

L L

(a × c) + (a × d) + (b × c) + (b × d)

These are just some equivalent fractions of 8/4:

2/1 = 4/2 = 6/3 = 8/4

= 10/5 = 12/6 = 14/7 = 16/8

= 18/9 = 20/10 = 22/11 = 24/12

= 26/13 = 28/14 = 30/15 = 32/16

= 34/17 = 36/18 = 38/19 = 40/20

= 42/21 = 44/22 = 46/23 = 48/24

= 50/25 = 52/26 = 54/27 = 56/28

= 58/29 = 60/30 = 62/31 = 64/32

= 66/33 = 68/34 = 70/35 = 72/36

= 74/37 = 76/38 = 78/39 = 80/40

= 82/41 = 84/42 = 86/43 = 88/44

= 90/45 = 92/46 = 94/47 = 96/48

= 98/49 = 100/50 = 102/51 = 104/52

= 106/53 = 108/54 = 110/55 = 112/56

= 114/57 = 116/58 = 118/59 = 120/60

= 122/61 = 124/62 = 126/63 = 128/64

= 130/65 = 132/66 = 134/67 = 136/68

= 138/69 = 140/70 = 142/71 = 144/72

= 146/73 = 148/74 = 150/75 = 152/76

= 154/77 = 156/78 = 158/79 = 160/80

= 162/81 = 164/82 = 166/83 = 168/84

= 170/85 = 172/86 = 174/87 = 176/88

= 178/89 = 180/90 = 182/91 = 184/92

= 186/93 = 188/94 = 190/95 = 192/96

= 194/97 = 196/98 = 198/99 = 200/100

So, yes.

Answer:

I guess -1/2?

Step-by-step explanation:

Answer: 0

0 is closest to 7/18 on a number line. -1 is 1 farther than zero. -1/2 is one half way from the number 7/18. So, the answer to the question is 0.

Given:

[tex]y=x^2+6x-1[/tex]

[tex]\dfrac{x}{r}=-3[/tex]

To find:

The given equation in terms of r if [tex]\dfrac{x}{r}=-3[/tex].

Solution:

Given that,

[tex]\dfrac{x}{r}=-3[/tex]

[tex]x=-3r[/tex]

We have,

[tex]y=x^2+6x-1[/tex]

Substitute x=-3r in the above equation.

[tex]y=(-3r)^2+6(-3r)-1[/tex]

[tex]y=9r^2-18r-1[/tex]

Therefore, the required equation in terms of r is [tex]y=9r^2-18r-1[/tex].

Step-by-step explanation:-9 turns to 9 then -4-9=13

Answer:

Step-by-step explanation:

In graphing inequalities, the first thing to do is graph the equation first irregardless of the inequality symbol. In the given problem, the equation to be graphed is f(x) = 2/9x + 3. Since it has a general form of y=mx + b, this is a linear function. Plot the graph by assigning arbitrary points of x, then you get the corresponding f(x) values. Graph the x values against the f(x) values. The blue line the attached picture will be formed.

Next, you solve the equation by finding x. Just don't mind the inequality symbol:

2/9 x + 3 > 4 5/9

2/9x > 4 5/9 - 3

2/9x > 14/9

x > 14/9 ÷ 2/9

x > 7

Hence, the value of x must be greater than 7. To show this in the graph, find the line where x=7. Create a partition using that line, then shade the rest of the portion where x is greater than 7 until infinity.

Answer: (-6,0) and (-8,0)

!!!!!!Also it's fixed now so ignore my comment about this being wrong!!!!!!

Step-by-step explanation:

To find roots you're basically looking for the points on the graph where they touch the x axis. Those are your roots. You can also plug 0 and -0 in for x and find the coordinates that way with the equation.

Answer:

Two points.

(-8, 0) and (-6, 0)

Step-by-step explanation:

The roots of a graph are another word for the zeros of a graph. In other words, the roots or zeros of a graph are whenever the graph touches or crosses the x-axis. Another way to think about roots are that the roots of a graph are simply its x-intercepts.

From the graph, we can see that it does this twice: once at [tex]x=-8[/tex] and again at [tex]x=-6[/tex]. At both of these points, the graph crosses the x-axis.

Therefore, we will have two roots in this case: one at (-8, 0) and another one at (-6, 0).

So, our answer is two points, being: (-8, 0) and (-6, 0).

And we're done!

Answer:

x = 4

Step-by-step explanation:

y = - 3 is the equation of a horizontal line parallel to the x- axis.

A line perpendicular to it will therefore be a vertical line parallel to the y- axis with equation

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (4, - 6) with x- coordinate 4, thus

x = 4 ← equation of perpendicular line

The length and width in terms of the height h is  5h+3 feet and 6h-5 feet respectively, the volume will be  [tex]30h^3 - 7h^2 -15h[/tex] units and the height must be in the interval of [tex][0,\infty)[/tex].

According to the question,

The height of the rectangular prism is h.

The length of the rectangular prism  is  5h+3 feet

The width of the rectangular prism  is  6h-5 feet

The volume of the rectangular prism can be calculated as:

[tex]Length \times width \times height = Volume[/tex]

Substitute the value of height, length  and width in the formula:

[tex]V = (5h+3) \times (6h-5) \times h[/tex]

V = [tex](30 h^2 -7h-15)h[/tex]

[tex]V = 30h^3 - 7h^2 -15h[/tex]

The height is always positive. So, the interval in which the In what range must the height fall is [tex][0,\infty)[/tex].

The length and width in terms of the height h is  5h+3 feet and 6h-5 feet respectively and the volume will be  [tex]30h^3 - 7h^2 -15h[/tex] units

The height must be in the interval of [tex][0,\infty)[/tex].
