Answer:

(4, -1) is not a solution to the system

Step-by-step explanation:

The first point: (4,-1) doesn't satisfy the first inequality:

$y>x-5\\(-1) > 4-5\\-1>-1$

since we get to an absurd, because -1 cannot be strictly smaller than -1!

Answer:

The answer is the option D

$x\leq 7/13$

Step-by-step explanation:

we have

$-\frac{6}{5}(4-x)\leq -4(x+\frac{1}{2})$

Multiply by $-5$ both sides

$6(4-x)\geq 20(x+0.5)\\24-6x\geq20x+10\\24-10\geq 20x+6x\\14\geq 26x$

Rewrite

$26x\leq 14\\x\leq 14/26\\ x\leq 7/13$

xeze [42]

Answer: 136 ounces

Step-by-step explanation:

Given: The ratio of cranberries and raspberries is 8:9 .

Let quantity of cranberries= 8x , quantity of raspberries = 9x

If quantity of cranberries = 64 ounces

$\Rightarrow\ 8x=64\\\\\Rightarrow\ x=\dfrac{64}{8}\\\\\Rightarrow\ x=8$

Quantity of raspberries = 9(8) = 72 ounces

Total quantity = 64 ounces + 72 ounces = 136 ounces

Hence, the total weight of berries purchased= 136 ounces
