Answer:

x=−5/2 y+ 3/2

Step-by-step explanation:

Let's solve for x.

2x+5y=3

Step 1: Add -5y to both sides.

2x+5y+−5y=3+−5y

2x=−5y+3

Step 2: Divide both sides by 2.

2x/2

=

−5y+3

2x=

−5y+ 3/2

Answer:

x=−5/2 y+ 3/2

Answer:

0=w^2-5.2w-51

Step-by-step explanation:

51=width x length

length=width-5.2

substitute for length

51=width x (width-5.2)

51=w^2-5.2w

0=w^2-5.2w-51

Answer:

C lets look at were this line starts which is in between 7 and 8 right in the middle making it 7.5 it is negative because the point is on the negative side of our graph. Where the line ends in on positive 2 on the x-axis. -Your friend, Bill Cipher

Answer:

3a + b = 180

Step-by-step explanation:

Supplementary angles are angles that, when added, equal 180 degrees.

Let's use a to represent the unknown angle, and b to represent its supplement:

3a + b = 180

Answer:

A.)

Step-by-step explanation:

5.7^2+3.2^2=42.73

Sqrt of 42.73=6.5

Given :

Length of leg in a triangle = 3.2 cm

Length of leg of another triangle = 5.7 cm

We know that :

[tex]\color{hotpink}\tt {hypotenuse}^{2} \color{plum} = {base}^{2} + {height}^{2} [/tex]

Which means :

[tex] = \tt {3.2}^{2} + {5.7}^{2} = {h}^{2} [/tex]

[tex] =\tt 42.73 = {h}^{2} [/tex]

[tex] =\tt \sqrt{42.73} = h[/tex]

[tex]\hookrightarrow\color{plum} \tt6.5 \: cm= hypotenuse[/tex]

Thus, the hypotenuse of this triangle = 6.5 cm

Therefore, the correct option is (A) 6.5 cm

Answer:

Y = 2/3x + 3

Step-by-step explanation:

The number of new Fiji apple trees needed to maintain the same ratio is 40 trees.

Ratio is the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.

The ratio of Fiji apple to Gala apple = 160 : 120 = 4 : 3

If 30 new gala trees are planted, hence the number of gala trees increases to 150 (120 + 30). To maintain the same ratio:

Number of fiji apple = (4/3) * 150 = 200

New Fiji apple trees = 200 - 160 = 40

The number of new Fiji apple trees needed to maintain the same ratio is 40 trees.

Answer:

y = -10x + 5 and y = 2/5x + 1

Step-by-step explanation:

slope-intercept form is y = mx + b, where m = slope and b = y-intercept.

for your first problem, just plug in the m and b values to complete the equation.

1.) y = mx + b ⇒ y = -10x + 5

plug in -10 for x (slope) and 5 for b (y-intercept)

and for the second problem...

since you're given a value for slope as well as a coordinate pair, all you need to do is plug those values into the equation for their respective variables and then solve for b. (it doesn't matter what order you plug values in, but i'm going to fill them in in the order of the equation; y, m, and x)

1.) plug in -1 for y

y = mx + b ⇒ -1 = mx + b

2.) plug in 2/5 for m

-1 = mx + b ⇒ -1 = 2/5x + b

3.) plug in -5 for x

-1 = 2/5x + b ⇒ -1 = 2/5(-5) + b

now it's time to solve for b! start by multiplying 2/5 and -5.

-1 = 2/5(-5) + b ⇒ -1 = -2 + b

add 2 to both sides of the equation. on the right side, it cancels itself out. on the left side, adding 2 to -1 gives you 1.

and you're left with 1 = b! :)

therefore, y = 2/5x + 1

i hope this helps! have a great day <3

LIke i dont know, kinda reminds me of my x never knew how to- never mind. Like just put traingle or whatever

Answer:

Step-by-step explanation:

Question (1)

x² + 10x + 12

= x² + 2(5x) + 5² - 5² + 12

= [x² + 2(5x) + 5²] - 5² + 12

= (x + 5)² - 25 + 12 [Since, a² + 2ab + b² = (a + b)²]

= (x + 5)² - 13

Question (2)

y² - 6y - 15

= y² - 2(3y) - 15

= y² - 2(3y) + 3² - 3² - 15

= [y² - 2(3y) + 3²] - 3² - 15 [Since, a² - 2ab + b² = (a - b)²]

= (y - 3)² - 3²- 15

= (y - 3)² - 9 - 15

= (y - 3)² - 24

Answer:

Rise over Run.

Step-by-step explanation:

If it's on a line on a graph you count how many it goes up until it's aligned with the next point and then you count how ever many over until it hits it. So it could be 2 up and 4 over making the slope 2/4.

Answer:

[tex]\sqrt{15.25}[/tex]

Step-by-step explanation:

To find the distance, we can use the distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] when the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the points (-6.25,5) and (-3.75,2)

[tex]d=\sqrt{(-6.25-x_1)^2+(5-y_1)^2}\\d=\sqrt{(-6.25-(-3.75))^2+(5-2)^2}\\d=\sqrt{(-6.25+3.75)^2+(5-2)^2}\\d=\sqrt{(-2.5)^2+(3)^2}\\d=\sqrt{6.25+9}\\d=\sqrt{15.25}[/tex]

Therefore, the distance between the two coordinates is [tex]\sqrt{15.25}[/tex], or approximately 3.91.

Answer:

10b - 60

Step-by-step explanation:

So the question is asking to use the Distributive Property with giving the equation 10(b - 6).

So the distributive property is just multiplying the number outside the parenthesis with the numbers inside the parenthesis, so lets implement that :

(10 * b - 6 * 10)

10b - 60

Answer:

The answer is 6

Step-by-step explanation:

10(b - 6) =

10 x b = 10b

10 x 6 = 60

10b = 60

10/10  10/60

= 6

Answer:

Step-by-step explanation:

4). Surface area of front and back = 2(lengh × height)

                                                        = 2(7×3)

                                                        = 63 cm²

    Surface area of top and bottom = 2(length × width)

                                                          = 2(8×7)

                                                          = 112 cm²

     Surface area of left and right = 2(width × height)

                                                      = 2(8×3)

                                                      = 48 cm²

      Total surface area = 63 + 112 + 48

                                      = 223 cm²

5). Surface area of top and bottom = 2πr²

                                                          = 2π(4)²

                                                          = 32π

                                                          = 100.53 cm²

    Surface area of middle = h(π × d)

                                            = 4(π × 8)

                                            = 32π

                                            = 100.53 cm²

     Total surface area = 32π + 32π

                                     = 64π

                                     = 201.06 cm²

6). Surface area of front and back = [tex]2[\frac{1}{2}(\text{Base})(\text{Height)}][/tex]

                                                        = Base × Height

                                                        = 6 × 8

                                                        = 48 cm²

     Surface area of bottom = 6 × 11

                                             = 66 cm²

     Surface area of the left = 8 × 11

                                             = 88 cm²

     Surface area of right = 10 × 11

                                        = 110 cm²

      Total surface area = 48 + 66 + 88 + 110

                                      = 312 cm²
