Answer:
There intersecting lines
Step-by-step explanation:
5x+2y=-8
-5x -5x
2y=-8 -5x
/2 /2 /2
y=-4 -5/2x also
y=-5/2x - 4
&
y=5/2x - 19
neither parallel (slope is not the same)
or perpendicular (slope is not reciprocal or opposite signed)
hope i helped
Answer:the answer is 2,500 cm^3
Step-by-step explanation:
The textbook is $150 originally, so to find the price of the textbook on sale, multiply the original price by 12% (0.12). Then subtract 12% of 150 from 150.
Subtract 18 from 150.
Multiply the price of the textbook on sale by the sales tax of 8.25% (0.0825). Then add the tax price onto the sale price of the textbook.
Add 10.89 to 132.
The final price of the textbook is $142.89.
Answer:
x = 10
Step-by-step explanation:
Consecutive angles in a parallelogram are supplementary, thus
∠ A + ∠ B = 180, substitute values
9x + 8 + 8x + 2 = 180, that is
17x + 10 = 180 ( subtract 10 from both sides )
17x = 170 ( divide both sides by 17 )
x = 10
