Answer:
To find the x intercept, let y=0. To find the y-intercept, let x=0. Hence, the x-intercept of the given equation is -2 and the y-intercept is -5/2.
Step-by-step explanation:
Let - 5x - 4y = 10 be the given equation.
Simplify the whole equation by dividing both sides by -1 :
To get the x-intercept, simply let y=0 :
- 5x + 4(0) = -10 (substitution)
- 5x = -10 (evaluate)
- x = -2 (simplify by dividing both sides of the equation by 5)
To get the y-intercept, simply let x=0 :
- 5(0) +4y = -10 (substitution)
- 4y = -10 (evaluate)
- y = -10/4 (simplify by dividing both sides of the equation by 4)
- y = -5/2 (simplify the fraction)

Answer:
6
Step-by-step explanation:
Mr. Kramer has pencils for his class = 30
Students in his class = 22
Pencils he would like to give each student = 2
How many more pencils does Mr. Kramer need to buy so that each student will receive 2 pencils = ?
Total pencils Mr. Kramer need to buy so that each student will receive 2 pencils = 22 × 2
= 44
= 44 - 30
= 6
Mr. Kramer need to buy 6 more pencils so that each student will receive 2 pencils
Answer:
-13
-10
Step-by-step explanation:
A x = B
To find X
A ^ -1 A x = A ^ -1 B
x = A^ -1 B
x = -3/2 -5/2 2
-1 -2 4
Across times down
-3/2 * 2 + -5/2 *4 = -13
-1 *2 -2 * 4 = -10
The matrix is
-13
-10
