Answer:
9 pencils
Step-by-step explanation:
We know that the ratio is 5:3 and its pens to pencils. So, every 5 pens have 3 pencils. Now Jose has 15 pens, so his pen supply triples. therefore his pencil supply must also triple. So 3x3=9.
Answer:
y + 3 = 4(x + 1)
Step-by-step explanation:
- Point slope form: y - y1 = m(x - x1)
- GIVEN: In this case, (x1, y1) = (-1, -3) and m = 4
When you plug this information into the formula, it becomes:
This means that 1 and 3 are added to x or y because the equation has double negatives. Double negatives make a positive.
- Therefore, y -(-3) = 4(x -(-1)) becomes y + 3 = 4(x + 1)
