Step-by-step explanation:

y - 3 = 1/2(x - 0)

y - 3 = 1/2x - 0

y = 1/2x + 3

The sum of the equation is A = x² + x + 1

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the sum of the equations be represented as A

Now , the value of A is

Let the first equation be P

The value of P = 3x² + 4x - 1

Let the second equation be Q

The value of Q = -2x² - 3x + 2

Now , the value of A = P + Q

Substituting the values in the equation , we get

A = ( 3x² + 4x - 1 ) + ( -2x² - 3x + 2 )

On simplifying the equation , we get

A = ( 3x² - 2x² ) + ( 4x - 3x ) + ( 2 - 1 )

A = x² + x + 1

Therefore , the value of A is x² + x + 1

Hence , the equation is A = x² + x + 1

Answer:

Your answer is 61.

Step-by-step explanation:

43+[(96÷8) × 5]-42, first you have to divide 96 and 8.

96 divided by 8 is 12. next you multiply 12 and 5. 12 multiplied by 5 equals 60. then you take 60 and add the 43. you will get 103, then you take 103 and subtract 42, and you will get 61.

Example:

43 + [(96 ÷ 8) × 5] - 42

43 + [12 × 5] - 42

43 + 60 - 42

103 - 42

The definition of implied is something that was hinted at or suggested, but not directly stated. When a person looks at his watch and yawns multiple times as you are talking, this is an example of a situation where boredom is implied.

1.6y+y-4/15y+7/6y=21/3

We move all terms to the left:

1.6y+y-4/15y+7/6y-(21/3)=0

Domain of the equation: 15y!=0

y!=0/15

y!=0

y∈R

Domain of the equation: 6y!=0

y!=0/6

y!=0

y∈R

We add all the numbers together, and all the variables

1.6y+y-4/15y+7/6y-7=0

We add all the numbers together, and all the variables

2.6y-4/15y+7/6y-7=0

We calculate fractions

2.6y+(-24y)/90y^2+105y/90y^2-7=0

We multiply all the terms by the denominator

(2.6y)*90y^2+(-24y)+105y-7*90y^2=0

We add all the numbers together, and all the variables

(+2.6y)*90y^2+(-24y)+105y-7*90y^2=0

We add all the numbers together, and all the variables

105y+(+2.6y)*90y^2+(-24y)-7*90y^2=0

Wy multiply elements

-630y^2+105y+(+2.6y)*90y^2+(-24y)=0

We get rid of parentheses

-630y^2+105y+(+2.6y)*90y^2-24y=0

We add all the numbers together, and all the variables

-630y^2+81y+(+2.6y)*90y^2=0

Answer:

He walks 1030 meters if he walks across the park.

Step-by-step explanation:

In order to solve this question we will need to know that [tex]c^{2} = a^{2} + b^{2}[/tex] (were c is the length of the hypotenuse (the diagonal line) of a right angle triangle, and a and b are the legs (the sides that form a right angle). So them means that.....

Let "c" be the distance he will need to walk if he was going to go through the park

Let "a" be the distance he walks on King Street

Let "b " be the distance he walks on Queen Street, then.....

[tex]c^{2} = a^{2} + b^{2}[/tex]

[tex]c = \sqrt{a^{2} + b^{2} }[/tex]

(Now plug in the values of a and b and get.....)

c = [tex]\sqrt{500^{2} + 900^{2} }[/tex]

c = [tex]\sqrt{1060000 }[/tex]

c = 1029.563014............

So I would assume that you have to round to the nearest meter. And as a result we get 1030 meter.

5x+y=8 equation 1

Subsitute (1,3) in bothe equations if the right side is equal to.the left side of the equation then (1,3) is a solution

5(1)+3=8

1+2(3)=7

7 isn't equal to 5 so 1,3 is NOT a solution for this system of equations

Answer:

No, because substituting the given ordered pair doesn't yield two true expressions

Step-by-step explanation:

:)

We want to see which pair of triangles is equivalent by the Angle-Angle-Side criteria.

The correct option is 2, where we have two equal angles, and the bottom side is equal in both triangles.

The Angle-Angle-Side criteria means that if two triangles have an equal side, and the two correspondent angles also are equal, then these triangles are equivalent.

So we just need to see (by notation, not by how the triangles look like) in which ones we have two equal angles and one equal side.

That one is the second pair of triangles.

We can see that the two top angles are equal (two curves) and that the left angle in the left triangle is equal to the right angle on the other triangle (so we have two equal angles).

Also, the bottom side is equal on both triangles.

Then the angle-angle-side criteria is meet, meaning that these two triangles are equivalent.

Answer:

The answer is D-16

Step-by-step explanation:

Since we have x on one side, and 49 degrees on the other, both angles are the same, so we subtract 1 from 49 to get 48, so that 3x has to equal 48. So we just divide 48 by 3 to get 16, so x = 16.

Answer:

7 [tex]\frac{1}{2}[/tex] miles

Step-by-step explanation:

The problem above is under the topic, "Subtracting Mixed Numbers with Similar Fractions."

In order to find the answer, you have to subtract the whole number parts first.

12-5 = 7

Then, you have to subtract the fractional parts. All you have to do is to get the difference of the numerators and copy the denominator.

7/8 - 3/8 = [tex]\frac{4}{8}[/tex]

Therefore, 12 [tex]\frac{7}{8}[/tex] - 5 [tex]\frac{3}{8}[/tex] = 7 [tex]\frac{4}{8}[/tex] miles

Let's simplify: 7 [tex]\frac{1}{2}[/tex] miles
