Answer: Answer is (-3, 7)

Step-by-step explanation:

y = -x + 4 equ 1

y = 3x + 16 equ 2

Make x subject of formular in equ 1

x = 4 - y equ 3

Subatitute x = 4 - y in equ 2

y = 3(4-y) +16

y = 12 - 3y + 16

y + 3y = 12 + 16

4y = 28

y = 28/4 = 7

Substitute y = 7 in equ 1

7 = -x + 4

7 - 4 = -x

x = -3

Answer is (-3, 7)

Set them equal to each other. -x + 4 = -3x + 16 >>> (-x+3x)=(16-4) >>> 2x= 12 so x =6. Plug in x to an equation. Y= -(6) + 4 so y = -2. (6,-2) is the answer.

OPTION A

y= 3x+6

This equation satisfies for all the value given in the table.

For (0,6)

y = 3(0)+6 = 6

For (2,12)

y=3(2) +6 = 6+6= 12

And so on.

Square root of 75 plus square root of 3
olya-2409 [2.1K]
Answer:
6√3

Explanation:
Before we begin, remember the following:
\sqrt{a*b} = \sqrt{a}  *  \sqrt{b}
m \sqrt{a} + n \sqrt{a}  = (m+n) \sqrt{a}

Now, for the given:
75 can be written as 25*3
This means that:
\sqrt{75} = \sqrt{25*3}
Applying the above concept, we can find that:
\sqrt{75} = \sqrt{25*3} = \sqrt{25}  *  \sqrt{3}
Now, we know that:
√25 = 5 (we ignored the negative value)

This means that:
√75 = 5√3

Finally, we can compute the needed sum as follows:
√75 + √3 = 5√3 + √3 = 6√3

Hope this helps :)

The diameter of a circle is 10 kilometers. What is the circle's radius?<br> d=10 km
alexandr402 [8]

Step-by-step explanation:

Let diameter of the circle be d and radius be r.

\therefore \: r =  \frac{d}{2}  \\  \\   \therefore \: r =  \frac{10}{2}  \\  \\ \therefore \: r = 5 \: kilometers.

Hence radius of the circle is 5 kilometers.

nacks &amp; More sells a 3-pound bag of mixed nuts for $17.25. Healthy Snacking sells a 2.5-pound bag of mixed nuts for $13.75.
Leto [7]

The Unit price at Snacks & More is $5.75 per pound

Unit price is the price for a single unit of product.

Given that Snacks & More sells a 3-pound bag of mixed nuts for $17.25, hence:

Unit price at Snacks & More = $17.25 / 3 pound = $5.75 per pound

Healthy Snacking sells a 2.5-pound bag of mixed nuts for $13.75.

Unit price at Healthy Snacking = $13.75 / 3 pound = $4.58 per pound

The Unit price at Snacks & More is $5.75 per pound
