Answer:
A will be at 6,6
Step-by-step explanation:
I think this because the graph is the same so it most likely will be the at the same position. Hope this is right !
Answer:
D) 90 cupcakes and 20 cookies
Step-by-step explanation:
90(1.5) + 20(.75) = 135 + 50 = $185
90 + 20 is less than or equal to 120
185 is greater than 125
Why other options won't work:
A) 50(1.5) + 60(.75) = 75 + 12 [$87 is less than $125]
B) 60(1.5) + 40(.75) = 90 + 30 [$120 is less than $125]
C) 100 cupcakes + 30 cookies exceeds 120 treats
The value of x is -3.5
Because dividing both sides by -2.4 is going to get you a value of -3.5. And a negative divided by a negative is a positive. :D
Answer:
Step-by-step explanation:
(a)
For the quadratic equation of the form ,
The discriminant is given as:
Simplifying the given quadratic equation:
[(x-7)^2] - 62 = 19
∴ (x^2) - 14x + 49 = 81
∴ (x^2) - 14x - 32 = 0
Comparing with the standard form of quadratic equation:
a = 1; b = -14; c = -32
∴ Discriminant = (b^2) - 4ac = 196 + 128 = 324
Since Discriminant > 0,
The roots will be real and distinct.
(b)
This equation can be factored as:
(x - 16)(x + 2) = 0;
∴ x = 16 ; x = -2, are the two roots of the equation.
