Answer:
$10.25
Step-by-step explanation:
Set up a system of equations, so 3c + 2m = 7 and 2c + 4m = 8, where c = the cost of coffees, and m = cost of muffins
To solve multiply the first equation by -2(3c + 2m=7) so you get -6c -4m = -14 now add the two equations
-6c - 4m = -14
2c + 4m = 8 notice that -6c + 2c = -4c and -4m + 4m cancels, then -14+8=-6
so we have -4c = -6 so c = $1.50
To solve for m, substitute c = 1.50 so 3(1.50) + 2m = 7, so solve for m so
4.5 + 2m = 7, 2m = 2.5, so m = $1.25
So now solve the final problem 6(1.50) + 1(1.25) = $10.25

Answer: (x + 3)(x - 4)
Step-by-Step Solution:
We need to Factorize the given Quadratic Polynomial by using Splitting the Middle Term Method.
= x^2 - x - 12
= x^2 - 4x + 3x - 12
= x(x - 4) + 3(x - 4)
=> (x + 3)(x - 4)
Answer:
A; y- 4 = -2(x + 1)
Step-by-step explanation:
Here, we want to find the equation of the given line
The general form
is ;
y = mx + c
c is the y-intercept which is 2
So we have
y = mx + 2
The x-intercept where y = 0 is 1
Thus;
0 = m(1) + 2
0 = m + 2
m = -2
So the equation of the line is
y = -2x + 2
We can rewrite this in the point-slope form as:
y - 4 = -2(x + 1)
