Answer:

$Slope= -1$

Step-by-step explanation:

Step 1: Find the slope

$Slope\ Formula: \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Plug in the numbers and solve.

$Slope= \frac{-6-(-5)}{6-5}$

$Slope= \frac{-1}{1}$

$Slope= -1$

Answer: $Slope= -1$

Answer:

$y > \boxed{\cfrac{42}{5} }$

Step-by-step explanation:

Given inequality:

$\cfrac{y}{3} > 7 - \cfrac{y}{2}$

To solve for y.

Solution:

Rewrite the inequality as,

$\displaystyle \frac{1y}{3} > \frac{ - 1}{2} y + 7$

Adding 1/2y to both sides,

$\cfrac{1}{3} y + \cfrac{ 1 }{2} y > \cfrac{ - 1}{2}y + 7 + \cfrac{1}{2} y$

$\cfrac{5}{6} y > 7$

Multiplying both sides by 6/5:

$\cfrac{6}{5} \times \cfrac{5}{6} y > \cfrac{6}{5} \times 7$

$y > \boxed{\cfrac{42}{5} }$

Value of y is 42/5.

the ratio of red marbles to yellow marbles placed in a bag is 2:7. More marbles are added to the bag: 3 red and 3 yellow marbles

Anvisha [2.4K]

Answer: False.

Step-by-step explanation:

Initially, the ratio is 2:7

This means that if we have 2 red marbles, we must have 7 yellow ones.

The quotient here is 7/2 = 3.5

Now, if you add 3 marbles of each colour, then we have:

2 + 3 = 5 red marbles

7 + 3 = 10 yellow marbles.

Now the ratio is 5:10

This means that for every 5 red marbles, we have 10 yellow ones.

But now we can divide both numbers by the same positive integer, because they have a common factor equal to 5.

5/5 = 1

10/5 = 2

Then we have:

5:10 = 1:2

So the new ratio is 1:2

Then the ratio changed when we added the new marbles, which means that Maria was wrong.
