Answer:

Angles of the isosceles triangle are 36°, 72° , 72°

Step-by-step explanation:

Vertex angle : Base angle = 1 : 2

Vertex angle = x

Base angle = 2x

Sum of all angles of a triangle = 180°

          x + 2x + 2x = 180°

                      5x = 180

                        x = 180 ÷ 5

                        x = 36°

2x = 2 *36 = 72°

Angles of the isosceles triangle are 36°, 72° , 72°

The value of y given the inverse relationship is 5.

If two variables vary inversely, as one variable increases, the other decreases in value.

The equation that is used to represent inverse relationship is:

y = k/x

Where k is the constant of proportionality

k = yx

k = 4 x 15 = 60

y = 60 / 12

y = 5

Answer:

y = 5x + 2

Step-by-step explanation:

slope intercept form is y = mx+ b

the y- intercept is 0,2 so 2 is your b.

for m you do rise over run aka y/x. for every 5 rise up the x runs one so your slope(m) = 5

 so y=5x+2

Answer:

yes

Answer:

Step-by-step explanation:

Multiply part of the right side by - 4

2x = -4*1/4 + 4* 3x/4  + 4                             Combine

2x = - 1 + 3x + 4                                            Combine again

2x = 3 + 3x                                                    Subtract 3x both sides

2x - 3x = 3                                                     Combine

-x = 3                                                              Multiply by -1.

-1 * -x = - 1 * 3

x = - 3

Analyzing the quadratic functions, it is found that the correct option is D. The functions f and g have the same axis of symmetry, but the minimum value of f is less than the minimum value of g.

Looking at the graph, Function f has a minimum value of 1 at x = -3. Hence, the axis of symmetry is x = -3.

Function g has a minimum value of 6 at x = -3. Hence, the axis of symmetry is also x = -3.

Therefore, the functions f and g have the same axis of symmetry, but the minimum value of f is less than the minimum value of g.

Answer:

Option D - x = 3 3/5

Step-by-step explanation:

Lets make the left side into an improper fraction :

2 2/5 = 12/5

Now let's make both fraction into equivalent ones but with the same denominator :

2/3 = 10/15

12/5 = 36/15

Now we substitute the equivalent values back into the equation :

10/15 × x = 36/15

Now we multiply both sides by 15 to remove the denominators:

10 × x = 36

Now we divide both sides by 10 and simplify :

x = 36/10

x = 18/5

x = 3 3/5

So our answer will be Option D

Answer:

D(x=1).

Step-by-step explanation:

2(5x+8)=6x+20

10x+16=6x+20

10-6x+16=6x-6x+20

4x+16=20

4x+16-16=20-16

4x=4

4x/4=4/4

x=1

The solution to this equation is x = 1

Given the equation, we apply the distributive property.

2( 5x + 8 ) = 6x + 20

10x + 16 = 6x + 20

10x - 6x = 20 - 16

4x = 4

x = 4 ÷ 4

x = 1

Therefore, the value of this equation is x = 1
