The system of equations x+y=46 and 15x+9y=396 could be used to find the number of boxes of each item sold.
Step-by-step explanation:
Given,
Cost of one box of raspberry scones = $15.00
Cost of one box of lemon poppy seed muffins = $9.00
Total boxes sold = 46
Total revenue earned = $396
Let,
x be the number of raspberry scones sold.
y be the number of lemon poppy seed muffins sold.
According to given statement;
x+y=46 Eqn 1
15x+9y=396 Eqn 2
The system of equations x+y=46 and 15x+9y=396 could be used to find the number of boxes of each item sold.
I think it would be 2x+3y=$24
Adult tickets would be x
Child tickets would be y
I’m not 100% sure though sorry
Answer:
No <em>real</em> solutions (or has two complex roots)
Step-by-step explanation:
The discriminant, <em>b</em>² - 4<em>ac</em>, is the expression (<u><em>radicand </em></u>) of the quadratic equation:
.
The value of the discriminant determines the <u>nature</u> and the <u>number of solutions</u> given by the quadratic equation.
A discriminant with a negative value (or b² - 4ac < 0 ) means that the quadratic equation has no real solutions or two complex solutions. Quadratic equations with a negative discriminant also have no x-intercepts; thus, its graph will not cross the x-axis.
A. (−3, 3)
<span>3x – 4y = 21
</span>3(-3) - 4(3) = 21
-21 = 21 >>>>> not equal
B. (−1, −6)
<span>3(-1) - 4(-6) = 21
</span>21 = 21 >>>>>>>>>>Equal
C. (7, 0)
<span>3(7) - 4(0) = 21
</span>21 = 21>>>>>>>>>>equal
D. (11, 3)
<span>3(11) - 4(3) = 21
</span>21 = 21 >>>>>>>>>equal
Answer:
20
Step-by-step explanation:
1% of 500 is 5
5*4(amount of years) = £20
