Answer:
Step-by-step explanation:
1a. -3 * -4 = 4 * 3
b.7(4+11) = 7(4) + 7(11)
c.6(7-4) = 6(3) - (0) *4
d. -2(6*(-5)) = -2*6*(-5)
2a.-60+4 = -56 = 50
b.-20 / 3 = 6.6 = 6.0 = 6
c. 2.4 = 2.0 = 2
d. 47.19 =40.00 = 40
e. 35.624+ (-4.17) = 31.454 =30.000 = 30
Answer: any set of the choices given can make a triangle.
The shapes and sizes will be different, of course. None of the sets given will produce a Right Triangle.
Step-by-step explanation:
Answer:
Not an exponential function. The exponent is a constant.
Step-by-step explanation:
An exponential function has the variable in the exponent. This function raises the variable to a fixed power, so it is not an exponential function.
Answer:
[4 -2 -19]
[-1 1 8]
Step-by-step explanation:
[ 2 5] * [a b c] = [3 1 2]
[ 1 3] ld e f] [1 1 5]
[2a+5d 2b+5e 2c+ 5f] = [3 1 2]
[a+3d b + 3e c + 3f] [1 1 5]
Solving systems of equations:
2a + 5d = 3
a + 3d = 1
2a + 6d = 2
Subtract -d = 1 so d = -1
and a = 1 - 3d = 1 - 3(-1) = 4
So d = -1 and a = -4.
In the same way we find that b = -2, e = 1, c = -19, f = 8.
