The value of the two variables 'x' and 'y' will be 2 and 5, respectively.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

There are two figures. The second number is one greater than twice the first. The total of the number's reciprocals is 7/10.

Let the two numbers be 'x' and 'y'. Then the equations are given as,

y = 2x + 1 ...1

1/x + 1/y = 7/10 ...2

From equations 1 and 2, then we have

1/x + 1/(2x + 1) = 7/10

10(2x + 1 + x) = 7x(2x + 1)

30x + 10 = 14x² + 7x

14x² - 23x - 10 = 0

14x² - 28x + 5x - 10 = 0

14x(x - 2) + 5(x - 2) = 0

(14x + 5)(x - 2) = 0

x = 2, - 5/14

At x = 2, then the value of y is given as,

y = 2 (2) + 1

y = 5

The value of the two variables 'x' and 'y' will be 2 and 5, respectively.

Give your answer in simplest form.

Answers

Answer:

z = 3√13

Step-by-step explanation:

The length of z is the geometric mean of the segments of the longest side that share a common point with z. The shorter of those is 9; the longer one is 4+9 = 13. Then ...

z = √(9(13))

z = 3√13

Additional comment

In like fashion, ...

x = √(4(13)) = 2√13y = √(4·9) = 6.

These relations come about because all of these right triangles are similar. That means their side lengths are proportional.

long side/hypotenuse = z/13 = 9/z ⇒ z = √(9·13)

short side/hypotenuse = x/13 = 4/x ⇒ x = √(4·13)

short side/long side = 4/y = y/9 ⇒ y = √(4·9)

Step-by-step explanation:

If you like my answer than please mark me brainliest

Answer:

The numbers are : 60 , 62

Step-by-step explanation:

Let the two consecutive even numbers be 2x , 2x + 2

2x + 2x + 2 = 122

Combine like terms

4x + 2 = 122

Subtract 2 from both sides

4x = 122 - 2

4x = 120

x = 120/4

x = 30

2x = 2*30 = 60

2x + 2 = 2*30 + 2 = 60 + 2 = 62

Parts of an Isosceles Triangle:
• The angle where the legs intersect is called the
• The side opposite the vertex angle is called the
• The angles along the base are called

Answers

Answer:

Vertex angle.Base.Base angles.

Step-by-step explanation:

Using the Base Angles Theorem to define the terms relating to an isoceles triangle:

The Base Angles Theorem states that if the two sides of a triangle are congruent, then it means that the angles opposite to those sides are also congruent.

An isoceles triangle has two congruent sides, referred to as the legs. As the legs of a triangle are slanted, they will intersect at a point known as the vertex angle. The side that is opposite to the vertex angle is the base of the triangle.

Therefore, the following are the missing terms in the given problem:

The angle where the legs intersect is called the vertex angle.The side opposite the vertex angle is called the base.The angles along the base are called base angles.

In 1993, the moose population in a park was measured to be 4650. By 1998, the population was measured

A.) Find a formula for the moose population, P, in terms of t, the years since 1990.
P(t) =
B.) What does your model predict the moose population to be in 2006?

Answers

Answer:

Here plz give brainliest not easy to explain in detail like this

Step-by-step explanation:

We will consider x on the graph to be years since 1990 and y on the graph to be the number of Moose.

We have two points on the graph: (4, 4290) and (8, 3850)

Using the slope formula (m = [y2 - y1]/[x2 - x1]), we can find the slope of this line:

m = (y2 - y1)/(x2 - x1) Slope formula

m = (3850 - 4290)/(8 - 4) Substitution

m = -440/4 Solve the subtraction problems in the parenthesis

m = -110 Reduce the fraction

Now that we have the slope of the line, we can use the point-slope formula (y - y1 = m[x - x1]) to find the equation for the line. I will use the first point, but either point will produce the same answer.

y - y1 = m(x - x1) Point-slop e formula

y - 4290 = -110(x - 4) Substitution

y - 4290 = -110x + 440 Distribute the -110

y - 4290 + 4290 = -110x + 440 + 4290 Add 4290 to each side

y = -110x + 4730 Simplify

Since the formula that is being sought is supposed to be interms of P and t, I will replace y with P and x with t.

P(t) = -110t + 4730

To predict the population in 2006, we need to determine the years from 1990 to 2006.

2006 - 1990 = 16

P(16) = -110 (16) + 4730

P(16) = -1760 + 4730

P(16) = 2970

Answer:

x = 8 and y = 21

Step-by-step explanation:

3y + 27 = 90 so 3y = 90 -27 which is 63 and to get y you divide 63 by 3 to get 21

Angles on a straight line add up to 180 so 180 = x + 90 + 8x + 18

Then you minus 90 from 180 to get 90 = x + 8x + 18 which simplifies to 90 = 9x + 18

Then you minus 18 from 90to get 72 = 9x

Then divide 72 by 9 to get x = 8

Now we can divide 60 by 10:
60 divided by 10 is 6

Finally we can multiply both 7 and 3 by 6:
7 x 6 = 42
3 x 6 = 18

To check we can add 42 and 18: this gives us 60.
