Simplify the expression: (− 2/3 pq^4)^2·(−27p^5q)

VladimirAG [237]

Answer:

-12p^7q^9

Step-by-step explanation:

(-2/3Pq^4)^2×(-27P^5q)

= ((-2)^2)/3^2 × P^2 q^4-2 × (-27qp^5)

= ((-2)^2)/3^2 × 27p^7q9

= (((-2)^2 x 27p^7q9)/3^2

= -((4×27p^7q^9)/9)

= -(108p^7q^9)/9

= -12p^7q^9

Figure A is a scale image of figure B. Figure A maps to figure B with a scale factor of 2 1/2. What is the value of x? PLEASE AN

tigry1 [53]

Answer:

$x = 2$

Step-by-step explanation:

Figure B = 2½ the size of figure A

One side of figure B is given as 5, therefore, 5 = 2½ of x in figure A.

Thus, $5 = 2\frac{1}{2}*x$

Solve for x

$5 = \frac{5}{2}*x$

$5*2 = \frac{5x}{2}*2$

$10 = 5x$

$\frac{10}{5} = \frac{5x}{5}$

$2 = x$

$x = 2$

point A lies at the intersection of y = x and y = -2/3x + 5. What are the coordinates of A? Express your answer as an ordered pa

torisob [31]

Y = x
y = -2/3x + 5

x = -2/3x + 5
x + 2/3x = 5
3/3x + 2/3x = 5
5/3x = 5
x = 5 * 3/5
x = 15/5 reduces to 3

y = x
y = 3

so ur answer is (3,3)
