6 0

Answer:

D. (1,0)

Step-by-step explanation:

Just plug in each coordinate for x and y into 4x+2y and see which one is less than or equal to 6.

Lets go through all of the possible answers:

A. (0,4)

4(0) + 2(4) ≤ 6

0 + 8 ≤ 6

8 ≤ 6

This is false. 8 is not less than or equal to 6.

B. (5,0)

4(5) + 2(0) ≤ 6

20 + 0 ≤ 6

20 ≤ 6

This is false. 20 is not less than or equal to 6.

C. (5,7)

4(5) + 2(7) ≤ 6

20 + 14 ≤ 6

34 ≤ 6

This is false because 35 is not less than or equal to 6

D. (1,0)

4(1) + 2(0) ≤ 6

4 + 0 ≤ 6

4 ≤ 6

This is true, because 4 is less than 6.

G(x)=−2(x+1)(x+7) find the zeros

Makovka662 [10]

When finding zeros, the function has to equal zero. In other words, G(x) = 0.

For three multiplied parts to equal to zero, at least one has to be zero. -2 ≠ 0, but (x+1) or (x+7) can.

So you can equate each of those to zero and find out what the zeros are.

x+1=0
x=-1

x+7=0
x=-7

Thus the answer
x = -1 or -7

Explain how modeling partial products can be used to find the products of greater numbers ?

liq [111]

You can break large numbers into a sum of a multiple(s) of 10 and the last digit of the number. For example, you can break 26 as 20+6, or 157 as 100+50+7.

Then, using the distributive property, you can turn the original multiplication into a sum of easier multiplications. For example, suppose we want to multiply 26 and 37. This is quite challenging to do in your mind, but you can break the numbers as we said above:

$26\times 37=(20+6)(30+7) = 20\times 30+20\times 7+30\times 6+6\times 7$

All these multiplications are rather easy, because they either involve multiples of 10 of single-digit numbers:

$20\times 30+20\times 7+30\times 6+6\times 7 = 600+140+180+42=962$

Three times the square of a number if five less than sixteen times the number. What is the number?

expeople1 [14]

X - the number

$3x^2=16x-5 \\
3x^2-16x+5=0 \\
3x^2-15x-x+5=0 \\
3x(x-5)-1(x-5)=0 \\
(3x-1)(x-5)=0 \\
3x-1=0 \ \lor \ x-5=0 \\
3x=1 \ \lor \ x=5 \\
x=\frac{1}{3} \ \lor \ x=5$

The number is 1/3 or 5.
