Answers

Answer 1

Answer:

y=-2x+4

Step-by-step explanation:

equation: y-y1=m(x-x1)

x1=0,y1=4,m=-2

y-4=-2(x-0)

y-4=-2x

y=-2x+4

If x + 2y = 15, what is the value of 3x + 6y/5

Answers

Answer:

I think 9 is the best answer

Answer:

9 is the answer.

Step-by-step explanation:

Given:

x + 2y = 15

We can tell that '3x + 6y' is basically '15 x 3' because the whole equation has been multiplied by three. Therefore, 3x + 6y must equal 45.

=> 3x + 6y = 45

But we need to divide 45 by 5 to get the solution because the 3x + 6y has also been divided by 5.

=> 45/5

=> 9

Therefore, 9 is the answer.

Brennan studied the relationship shown in the table.

x 3 4 5 6 7
y 36 48 60 72 ?

Which expression describes a method Brennan could use to determine the y-value when x equals 7?

Answers

Answer:

y = 12x

Step-by-step explanation:

Note the relationship

x = 3 : y = 36 , that is 36 = 12 × 3

x = 4 : y = 48, that is 48 = 12 × 4

x = 5 : y = 60 , that is 60 = 12 × 5

x = 6 : y = 72 , that is 72 = 12 × 6

The value of y is obtained by multiplying corresponding x value by 12

Then

x = 7 → y = 12 × 7 = 84

in general for any x

y = 12x

I need help solving for Y

Answers

Answer:

y=24

Step-by-step explanation:

since the triangles are similar, their sides are all in proportion

meaning:

[tex] \frac{20}{15} = \frac{32}{y} [/tex]

simplify the fraction

[tex] \frac{4}{3} = \frac{32}{y} [/tex]

cross multiply once the fraction is simplified

[tex]96 = 4y[/tex]

y=24

Answer:

y = 24

Step-by-step explanation:

the first triangle 20 : x : 32

the 2nd triangle 15 : 21 : y

Solve the equation of two triangles by similarity

x = [tex]\frac{21 * 20}{15}[/tex] = 28

y = [tex]\frac{21 * 32}{28}[/tex] = 24

A cash card has a starting value of $25. If the card is not used within the first year of its purchase, the value on the card begins to decrease by $2.50 per month.
The relationship between the number of months after the first year and the amount remaining on the card is .

The independent variable is the _____________?

The dependent variable is the ______________?

Answers

Answer:

The relationship between the number of months after the first year and the amount on the remaining card is linear and inverse ( Which meant that ,when the number of months after the first year increases , the amount on the remaining car decreases , in a linear way ) .

The Independent variable is the numbers of months after the first year .

The Dependent variable is the amount on the remaining card , Bcoz this amount depends on the time it has passed since the first year , ( which is our independent variable!).

If we call "Y" our dependent variables and "X" our Independent variable , This relationship can be written as Y= 25 - 2.5x.

If no months had passed since the first year, then x= 0 and the amount in the card equals $25 , While if one month has passed since the first year x= 1 and y= 22.5 ( The amount in the card in this case is $22.5 .

[tex]\huge\boxed{x=29;\ y=51}[/tex]

Step-by-step explanation:

This is Isosceles triangle (look at the picture).

We know:

All triangles have internal angles that add up to 180°

Therefore:

[tex](x-2)+(x-2)+(4x+10)=180[/tex]

combine like terms:

[tex](x+x+4x)+(-2-2+10)=180\\\\6x+6=180\qquad|\text{subtract 6 from both sides}\\\\6x=174\qquad|\text{divide both sides by 6}\\\\x=29[/tex]

(x - 2)° and 3y° are supplementary angle (Two Angles are Supplementary when they add up to 180°).

Therefore:

[tex]3y+(x-2)=180[/tex]

substitute x = 29 and solve for y:

[tex]3y+(29-2)=180\\\\3y+27=180\qquad|\text{subtract 27 from both sides}\\\\3y=153\qquad|\text{divide both sides by 3}\\\\y=51[/tex]

Answers

Answer:

  (c)  3,477.4 cm³

Step-by-step explanation:

The formula for the volume of a sphere is ...

  V = 4/3πr³ . . . . where r is the radius

The radius is half the diameter, so is 18.8 cm/2 = 9.4 cm.

Using this value and the value for pi in the formula, we have ...

  V = (4/3)(3.14)(9.4 cm)³ = (4/3)(3.14)(830.584 cm³) ≈ 3477.4 cm³

Step-by-step explanation:

Simplifying

13x + 6y = 180

Solving

13x + 6y = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6y' to each side of the equation.

13x + 6y + -6y = 180 + -6y

Combine like terms: 6y + -6y = 0

13x + 0 = 180 + -6y

13x = 180 + -6y

Divide each side by '13'.

x = 13.84615385 + -0.4615384615y

Simplifying

x = 13.84615385 + -0.4615384615y
