Write the linear system:

Mathematics
1 answer:
notsponge [240]3 years ago
8 0

Answer:

(See explanation for further details).

Step-by-step explanation:

C) The linear system is:

(-1)^{2} \cdot a + (-1)\cdot b + c = 5

c = - 4

(4)^{2}\cdot a + (4)\cdot b + c = 0

After some algebraic handling:

a - b + c = 5

c = -4

16\cdot a + 4\cdot b + c = 0

By direct substitution:

a - b - 4 = 5

16\cdot a + 4\cdot b - 4 = 0

a - b = 9

4\cdot a + b = 1

a = 9 + b

4\cdot (9+b)+b = 1

36 + 5\cdot b = 1

5\cdot b = -35

b = -7

a = 2

D) The parameter values are: a = 2, b = -7, c = -4

E) The quadratic equation is y = 2\cdot x^{2} - 7\cdot x -4

PLEASE SEND HELP!
Neporo4naja [7]

Answer:

2000 times 3.5% is 70, so in one year you would have 2070 dollars. 3.5 divided by 3 is about 1.16 (the six repeats), so for the next 1/3 year you would do 2070 times 1.16 percent which is 30. So, then, 2070 plus 30 is 2100 dollars in the saving account.

If anyone can help me it would be appreciated I will give out 50 points I need answers quick.
Allushta [10]

Answer:

Step 4

Step-by-step explanation:

Tasha was correct in all the steps leading up to the fourth one. However, in the fourth step was where she messed up.

She said that: \frac{1}{256} =-\frac{1}{4^{-4}}=4^{-4}

However, when we have a negative exponent, in order to get rid of the negative, we simply take the reciprocal of the number and then make the exponent positive. Here, the answer should be:

\frac{1}{256} =\frac{1}{4^{4}}=4^{-4}

What is the slope of the line that contains the points (-1,2) and (2,2)
MAVERICK [17]

Answer:

the equation to find the slope is (y2-y1)/(x2-x1)

the points are (-1,2) and (2,2) so plug it in and you get

(2-2)/(2-(-1))

0/ (2+1)

0/3

whenever the numerator is 0, that means the slope is 0. the line is just a horizontal line.
