Simultaneous Equation (x+5)(x+2)=65 , xy=24 Plssss help me ✌

Ne4ueva [31]

Answer:

(-11.70, -2.05), (4.70, 5.10)

Step-by-step explanation:

Given equations

(x+5)(x+2)=65
xy=24

Solving the first equation for x:

(x+5)(x+2)=65
x^2 + 7x + 10 = 65
x^2 + 7x - 55 = 0
x = (-7 ± √(49+4*55))/2
x = -11.70, x = 4.70

Then solving for y:

y= 24/(-11.7) = -2.05
y = 24/4.7 = 5.10

Solution set:

(-11.70, -2.05), (4.70, 5.10)

Triangle ABC has the following coordinates: A (-2, 3) B (4, -3) C (-2, -3) What are the coordinates points for triangle A'B'C' i

hodyreva [135]

Answer: The coordinates of triangle A'B'C',

A'≡(3/2, -9/4)

B'≡(-3, 9/4)

C'≡(3/2, 9/4)

Step-by-step explanation:

Since, the rule of transforming the triangle ABC by the scale factor -3/4,

$(x,y)\rightarrow (\frac{-3}{4}x, \frac{-3}{4}y)$

Thus, the coordinates of the transformed triangle A'B'C',

$(-2, 3)\rightarrow (\frac{-3}{4}\times -2, \frac{-3}{4}\times 3)$

$(4, -3)\rightarrow (\frac{-3}{4}\times 4, \frac{-3}{4}\times -3)$

$(-2, -3) \rightarrow (\frac{-3}{4}\times -2, \frac{-3}{4}\times -3)$

So, the coordinates are A'≡(3/2, -9/4)

B'≡(-3, 9/4)

C'≡(3/2, 9/4)
