Answer:

Step-by-step explanation:

$slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{-6-6}{7-[-5]}\\\\=\frac{-12}{7+5}\\\\=\frac{-12}{12}\\\\=-1$

Step-by-step explanation:

a mother is a she, not a he ...

anyway, we need to make 2/3 and 3/4 comparable.

for this we need to bring both fractions to a common denominator, which is usually the smallest common multiple of the denominators.

yes, 12 is the smallest number that can be divided by 3 and by 4 without remainder.

to transform a fraction too another denominator, we need to multiply it by a fraction a/a, which has the value 1, of course (so we don't change the value of the original fraction), but changes the denominator to the desired number.

what do I multiply with 4 to get 12 ? 3.

so, I multiply 3/4 by 3/3 = 9/12.

what do I multiply with 3 to get 12 ? 4.

so, I multiply 2/3 by 4/4 = 8/12.

now we can compare and calculate :

out of the total of 9/12kg 8/12kg were used.

that means

1/12kg of carrots are left.

this is a strange question, as watermelons, bananas and melons are very differently sized. so, for example 1/2 watermelon and 1/2 banana are very different quantities.

so, what does e.g. 1 fruit mean ?

or if we understand the fractions as shares of the overall smoothie, then we have too much. 4/6 (watermelon) + 2/6 (melon) = 6/6 = 1 (whole smoothie).

so, what to do with the banana ?

this question does not make any sense at all.

but if it is just to add fractions, we can do that :

4/6 + 1/2 + 2/6

as mentioned above, 4/6 + 2/6 = 6/6 = 1

1 + 1/2 = 2/2 + 1/2 = 3/2 = 1.5 or 1 1/2

so there is 1 1/2 fruit in the smoothie (whatever that means).

1 1/2 + 2 1/2 = 2/2 + 1/2 + 4/2 + 1/2 = 8/2 = 4

in total, there are 4 cups of sugar needed.

In 3/4 pound of a spice mix, there is 5/6 cup of cinnamon. How much cinnamon does the spicemix contain per pound?

GuDViN [60]

Let's use ratio and proportion or rates to solve thisIf there is 5/6 cup of cinnamon in a 3/4 pound of spice mix, how many are in a pound?5/6=3/4 ?=11/ (3/4)*5/6=11/9Therefore there are 10/9 cups of cinnamon in 1.111... or 11/9 pounds of spice mix.

Option B: $y=-\sqrt[3]{x-4}+7$ is the new equation

Explanation:

The given equation is $y=-\sqrt[3]{x}$

We need to find the new graph which is shifted 7 units up and 4 units right.

First, we shall shift the graph 7 units up.

The general formula to shift the graph b units up is given by

$y=f(x)+b$

Thus, to shift the graph 7 units up, let us substitute $b=7$ and $f(x)=-\sqrt[3]{x}$ in the general formula, we have,

$y=$-\sqrt[3]{x}$+7$

Now, we shall shift the graph 4 units right.

The general formula to shift the graph b units right is given by

$y=f(x-b)$

Thus, to shift the graph 4 units right, let us substitute $b=4$ and $f(x)=$-\sqrt[3]{x}+7$$ in the above equation, we have,

$y=-\sqrt[3]{x-4}+7$

Therefore, the new equation is $y=-\sqrt[3]{x-4}+7$

Therefore, Option B is the correct answer.

find the slope of the line AB
m=(y2-y1)/(x2-x1)=(172-160)/(30-22)=12/8=3/2=1.5m=1.5
one point and slope-------- > A(22.160) m=1.5
y=mx+b
160=1.5(22)+bb=127y=1.5x+127---------- > equation in slope intercept form
