Answer: $140
Step-by-step explanation:
1/4 × 560 to buy a coat
= 0 25 x 560 = $140
Remaining balance after purchase of coat will be $560 - $140 = $420
Next, he uses 2/3 of $420 for present
2/3 × 420
0.667 x 420
= $280 for present
Alice's balance will be remaining balance after purchase of coat - money for present
= $420 - $280
=$140
I hope this is clear, please mark as brainliest answer. Thank you.
Answer:
Option A, E ,F are correct
Step-by-step explanation:
f(x).g(x)=(8x^2+4)(-x^2+12x+10)
=(-8x^4+96x^3+80x^2-4x^2+48x+40)
= -8x^4+96x^3+76x^2+48x+40
Leading term is -8x^4. The x term has coefficient 48. The x^2 term has coefficient +76
In the given diagram, the measure of angle DAE is 48°
<h3>Circle Geometry </h3>
From the question, we are to determine the measure of angle DAE
From the given information,
96° is the angle subtended by the arc at the center of the circle
From one of the circle theorem,
Angle at the center is <u>twice</u> the angle at the circumference
∴ 2 × ∠DAE = 96°
∠DAE = 96°/2
∠DAE = 48°
Hence, the measure of angle DAE is 48°

7x + 5y = 19
<u>-7x - 2y = -16</u>

3 3
y = 1
7x + 5y = 19
7x + 5(1) = 19
7x + 5 = 19

x = 2
(x, y) = (2, 1)
The method would be a elimination method (the answer is C).
(x; y)
reflect over
x axis (x; -y)
y axis (-x; y)
therefore
(-2; 3)
x axis (-2; -3)
y axis (2; 3)
