Answer:

750 grams of protein, 222.22 of fat, and 1,250 of carbs.

Step-by-step explanation:

3,000 calories from protein, 2,000 from fat, and 5,000 from carbs.

3000 / 4 = 750 grams of protein.

2,000 / 9 = 222.22 grams of fat.

5,000 / 4 = 1,250 grams of carbs.

Explain why this matrix equation has no solution: A 11 17 −8 13 = 0 0 0 0.
qwelly [4]

The matrix equation has no solution because the same matrix of equal magnitude and opposite in nature is been added to it.

Given to us

A + [11   17   -8    13] = [0   0   0   0]

<h3>What is the value of matrix A?</h3>

We know that the given matrix will give values as zero if the same matrix is been deducted from it, therefore,

A + [11   17   -8    13] = [0   0   0   0]

A = [0   0   0   0] - [11   17   -8    13]

A = [-11   -17   +8    -13]

Thus, the matrix is equal to [-11   -17   +8    -13].

<h3>why this matrix equation has no solution?</h3>

The matrix equation has no solution because the same matrix of equal magnitude and opposite in nature is been added to it, therefore, [11   17   -8    13] is been added to it.

Thus, the sum of the two matrices has no solution.

Neporo4naja [7]

Answer: y=<em>300</em>-40x

The <em>y-intercept</em> would be 300

The slope would be -40

Step-by-step explanation:

x=number of months

300 is the amount she starts with

Equation can also be written like so;  y=-40x+300 just like in y=mx+b (slope intercept) form
