F(x) = y
10= x2 - 7x -13
10= -5x -13
-10 -10
5x = -23
Answer is X = -23/5 or -4.6
<span>To find StDev, we first have to find the mean of the squared differences. The differences between each score and the mean are 0,-2,2, respectively, giving squared values of 0,4,4. To find the variance, we take the sum of the three values and divide it by the number of values in the total set (3). This gives 8/3 or 2.6667. To find the population StDev, then, take the square root of the variance (2.6667), to find 1.633.</span>
Answer:
answer for y=2/3x+2: y=2/3x+2
answer for -2x+3y=6: x=3/2y-3

they all equal 4, so yes Alexa is correct.
Answer:
12 liters of fruit.
88 liters of ginger ale.
Step-by-step explanation:
100 = g + f
130 = 1g + 1.5f
f = 12
because u can use elimination by multiplying equation 2 by -1 to cancel out g variable then combine both equations
g = 88
because plug in f's value of 12 to 1st equation then subtract 12 from each side
