Mathematics
1 answer:
MatroZZZ [7]3 years ago
8 0

a. (3,4) is only the solution to Equation 1.

(4, 2.5) is the solution to both equations

(5,5) is the solution to Equation 2

(3,2) is not the solution to any equation.

b. No, it is not possible to have more than one (x,y) pair that is solution to both equations

Step-by-step explanation:

a. Decide whether each neither of the equations,

i (3,4)

ii. (4,2.5)

ill. (5,5)

iv. (3,2)

To decide whether each point is solution to equations or not we will put the point in the equations

Equations are:

Equation 1: 6x + 4y = 34

Equation 2: 5x – 2y = 15

<u>i (3,4) </u>

Putting in Equation 1:

6(3) + 4(4) = 34\\18+16=34\\34=34\\

Putting in Equation 2:

5(3) - 2(4) = 15\\15-8 = 15\\7\neq 15

<u>ii. (4,2.5)</u>

Putting in Equation 1:

6(4) + 4(2.5) = 34\\24+10=34\\34=34\\

Putting in Equation 2:

5(4) - 2(2.5) = 15\\20-5 = 15\\15=15

<u>ill. (5,5)</u>

6(5) + 4(5) = 34\\30+20=34\\50\neq 34

Putting in Equation 2:

5(5) - 2(5) = 15\\25-10 = 15\\15=15

<u>iv. (3,2)</u>

6(3) + 4(2) = 34\\18+8=34\\26\neq 34

Putting in Equation 2:

5(3) - 2(2) = 15\\15-4 = 15\\11\neq 15

Hence,

(3,4) is only the solution to Equation 1.

(4, 2.5) is the solution to both equations

(5,5) is the solution to Equation 2

(3,2) is not the solution to any equation.

b. Is it possible to have more than one (x, y) pair that is a solution to both

equations?

The simultaneous linear equations' solution is the point on which the lines intersect. Two lines can intersect only on one point. So a linear system cannot have more than one point as a solution

So,

a. (3,4) is only the solution to Equation 1.

(4, 2.5) is the solution to both equations

(5,5) is the solution to Equation 2

(3,2) is not the solution to any equation.

b. No, it is not possible to have more than one (x,y) pair that is solution to both equations

find the area of the shaded region of circle y below. Round your answer to the nearest tenth if necessary
S_A_V [24]

Answer:

  285.6 square units

Step-by-step explanation:

The shaded area can be described a a whole circle less a 90° segment, or as a 3/4 circle with a right triangle added. The formula for the segment area is that of a sector less the triangle, so the computation is the same either way.

__

<h3>3/4 circle area</h3>

The area of a circle is given by ...

  A = πr²

so 3/4 of a circle is 3/4 this value:

  3/4 circle area = (3/4)(π)(10²) = 75π . . . . square units

<h3>Triangle area</h3>

The area of the isosceles right triangle is given by ...

  A = 1/2s²

  A = 1/2(10²) = 50 . . . . square units

<h3>Shaded area</h3>

The shaded area is the sum of these two ...

  shaded area = 3/4 circle area + right triangle area

  shaded area = 75π + 50 ≈ 285.6 . . . . square units

Write an equation of the line that is parallel to 5x + 20y = 10 and passes through the point (8, 3).
torisob [31]

5x+20y=10\implies y=\dfrac12-\dfrac x4

is a line with slope -\dfrac14. Any line parallel to it will have the same slope. Using the point-slope formula, the equation of the parallel line passing through (8, 3) is

y-3=-\dfrac14(x-8)\implies y+\dfrac13x=5\implies x+3y=15
