What is the value of y for the line when x=-4

Answer:

x=-8

Step-by-step explanation:

-5=2x+3-x

-5=x+3

-5-3=x

-8=x

Hope I helped

Answer:

x = 5

y = 1/4

Step-by-step explanation:

Let a = 1/x

     b = 1/y

Then the equations are

(1)        10a - 4b = -14     and     (2)    5a + 8b = 33     Multiply equation (2) by -2

         -10a - 16b = -66

                  -20b = - 80

                        b = 4                         5a + 8(4) = 33

                                                          5a + 32 = 33

                                                                  5a = 1

                                                                    a = 1/5

a =  1/x = 1/(1/5)                   x = 5

b = 1/y = 4                           y = 1/4

Answer:

There are two ways you can find the slope(atleast thats what I know)

Step-by-step explanation:

Hello, i have two ways.

We can find the slope in y = mx+b form or the slope in y=mx+b itself

We can also find the slope with the graph drawn.

Step-by-step explanation:

13² = 5² + x²

x² = 13² - 5²

x² = 144

x = √144

x = 12

Answer:

∠ b = 23°

Step-by-step explanation:

Complementary angles sum to 90° , then

a + b = 90° , that is

67° + b = 90° ( subtract 67° from both sides )

∠ b = 23°

Answer:

m<b = 23

Step-by-step explanation:

Complementary angles have a sum of 90, so subtract 67 from 90 to get the measurement of the other angle.

Answer:

42°

Step-by-step explanation:

3x + 54° = 180° [Supplementary angles]

=> 3x = 180 - 54

=> 3x = 126

[tex] = > x = \frac{126}{3} [/tex]

=> x = 42° (Ans)

Answer:

3x+54= 180(linear pair are supplementary)

3x= 180-54

3x= 126

x= 126/ 3

x= 42°

Answer:

102

Step-by-step explanation:

You have to substitute x and y. Since x = 3 and y = 4, you would write the equation as 6(3) + 21(4). Multiply that, and you get 18 + 84. Add that together, and you get the answer 102.

Answer: 102

Step-by-step explanation: 6x + 2y

                                             6(3) + 21(4)

                                             18 + 84

                                             102

basically you just plug in 4 where it says y in the equation and plug in 3 where it says x in the equation and solve :))

100 is the answerrrrrrrrrrrrrrrrrrr

Answer:

$11.24

Step-by-step explanation:

Given data

Original cost of tire=  $74.95

DIscount= 15%

Required

The amount of the discount

=15/100*74.95

= 0.15*74.95

= 11.24

Hence the amount saved is $11.24

Answer:

[tex]h = - 12[/tex]

Step-by-step explanation:

1) Add 1 to both sides.

[tex] \frac{h}{6} = - 3 + 1[/tex]

2) Simplify -3 + 1 to -2.

[tex] \frac{h}{6} = - 2[/tex]

3) Multiply both sides by 6.

[tex]h = - 2 \times 6[/tex]

4) Simplify 2 × 6 to 12.

[tex]h = - 12[/tex]

Therefor, the answer is h = -12.

Answer:

h = - 12

Step-by-step explanation:

Add 1 to both sides of the equation

ℎ/6 − 1 + 1 = − 3 + 1

Simplify

ℎ/6 = − 3 + 1

h/6 = -2

Multiply all terms by the same value to eliminate fraction denominators

6 ⋅ ℎ/6 = 6 ( − 2 )

Cancel multiplied terms that are in the denominator

ℎ = 6 ( − 2 )

Multiply the numbers

ℎ = − 12

Answer:

  (4, -10), (4, 6)

Step-by-step explanation:

The vertical diameter is on the vertical line through the center of the circle. That line is x=4.

The square of the radius is 64, so the radius is √64 = 8. The y-coordinate of the diameter end points will be the y-coordinate of the center ±8.

So, the points of interest are ...

  (4, -2±8) = (4, -10) and (4, 6) . . . . end points of the vertical diameter

Answer:

x = 20.5

Step-by-step explanation:

Since you are given the hypotenuse and the adjacent side to 70 then you have the cos 70 = adj/hyp so cos 70 = 7/x so x = 7/cos 70, so x = 20.467

Answer:

85

Step-by-step explanation:

complementary angles = 90* so  85+5=90

Answer:

85

Step-by-step explanation:

Complementary means those angles add up to 90

supplementary means those angles add up to 180

because on angle is 5 degrease and it says complementary you just...

90-5=x

85=x

Answer:

A)20.00mm

Step-by-step explanation:

since the cube has 6 faces divide it by 6.

= 2400 ÷ 6

=400

1 face = 400 area

since the surface of the cube is square and its area is 'side square'

find the square root of 400

which is 20 cm (side)

Also, I took the test and got it correct.

Step-by-step explanation:

Trees give off oxygen, which living things breath. Animals also eat plants for food. And I think animal poop helps plants grow. BTW, this isn't really a math question. Hope this helps!

Answer:Plants and animals depend upon each other as mutual interdependence is must for their survival. Plants provide shelter for animals and they make oxygen for the animals to live. When animals die they decompose and become natural fertilizer plants.Plants depend on animals for nutrients, pollination and seed dispersal. Plants are also useful for animal home because many animals live around plants.
