A
A square matrix is invertible if its determinant is not zero.
The determinant for this matrix is
so it does not have an inverse because its determinant is zero.
Answer: 1.(-3.4)(5)=-17
2.(-8)(2.2)=17.6
3. (3.8)(-5)=-19
4.(-9.5)(-2)
Step-by-step explanation:
Answer:
39
Step-by-step explanation:
because the decimal is moved 39 times as shown by calculating the sum
Answer:
F(x) has a larger slope.
Step-by-step explanation:
f(x) has a slope of 10 and g(x) has a slope of 9. The slope of f(x) can be found by dividing 800 by 80 (800 / 80 = 10). The slope of g(x) can be found by using the rate of change formula: y2 - y1 / x2 - x1. Choose two of the points from the chart. I'll use (2, -6) and (4, 12). Plug in the numbers so the equation would be 12-(-6) / 4-2. This simplifies to 18 / 2 which is 9.
