What is the solution to the system of equations?

Mathematics
1 answer:
Vitek1552 [10]3 years ago
3 0
Multiply the 1st equation by 2 and the 2nd by 5 to get:
10x-6y= -18
10x-25y=20
subtract equation 2 from equation 1 and the x's cancel:
10x-6y= -18
10x-25y=20
19y= -38
y= -2
substitute y= -2 into either of the original equations to get x= -3
(-3, -2)

Write an equation of a piecewise defined function with the given conditions: domain is (-3, 2) u (2, ∞) range is (-1, ∞) functio
Korvikt [17]
\left \{ {{f(x)=x+2, -3\ \textless \ x\ \textless \ 2} \atop {f(x)=x-2, 2\ \textless \ x\ \textless \ infinity}} \right.

f(x) has to be close to -1 when x is close to -3, and so f(x) is increasing when x increases, and there are no numbers from -1 to ∞ that there is no f(x) value. In the first piece of the function <span>f(x) ranges from -1 to 4 and the second piece from 0 to ∞ so. The ranges had to overlap since it's not defined at x = 2.</span>

King Henry the 8th had six wives,some of which had the same names.One more was named Catherine(although with different spellings
valentinak56 [21]
2 more were named Catherine because since he had 6 wives, 2 were named Anne with a different spelling and since Jane is only one wife that means 2 wives plus 1 wife equals 3 but then there was Catherine so 2 wives plus 2 wives equals 4 wives so you subtract 4 wives from 6 wives and you get 2 wives or 2 Catherines.

1. sqrt5 + 6sqrt5 = (1+6)sqrt5 = 7sqrt5 (answer is D) 
2. 4sqrt2 - 7sqrt2 = (4-7)sqrt5 = -3sqrt2 (answer is B)
 3. 3sqrt7 - sqrt63 = 3sqrt7 - sqrt7 * sqrt9 = 3sqrt7 - 3sqrt7 = 0 (answer is D)
 4. -6sqrt10 + 5sqrt90 = -6sqrt10 + 5*(sqrt10 * sqrt9) = -6sqrt10 + 5*(3sqrt10)
= -6sqrt10 + 15sqrt10 = 9sqrt10 (answer is A)
 5. sqrt6*(sqrt 2 + sqrt 3) = sqrt12 + sqrt18 = 2sqrt3 + 3sqrt2 (answer is D)

Rhombus RSTU is congruent to rhombus
Harlamova29_29 [7]

Rhombus RSTU is congruent to WXYZ, and are translational images of each other because all their sides and angles are equal

<h3>What are the properties of a rhombus?</h3>

Some of the properties of a rhombus are;

  • The sides are congruent.
  • All the opposite sides are parallel to each other.
  • Diagonals bisect each other perpendicularly.
  • The angles are supplementary, that is, they add up to 180°

If Rhombus RSTU is congruent to WXYZ, then they are both translation images of each other because all their sides and angles are equal.
