Answer:

x is equal to 15.

Step-by-step explanation:

In order to solve this, we need to set it up as a proportion.

6/8 = x/20

Now that we have the proportion, we need to cross multiply to solve.

6*20 = 8*x

120 = 8x

15 = x

What is the distance between the points (-6, 7) and (-1, 1) ? Round to the nearest whole number

Answer:

7.8 rounded to the nearest whole number would be 8.

Step-by-step explanation:

-6 would be x1

7 would be y1

-1 would be x2

1 would be y2

Take these numbers and plug them into the distance formula:

$\sqrt{(x2-x1)^{2} + (y2-y1)^2}$

$\sqrt{(-1 - -6)^2 + (1-7)^2} \\\sqrt{(5)^2 + (6)^2\\\} \\\sqrt{25 + 36} \\\sqrt{61} = 7.81$

Simplify. (-6x^2 + 2y - 1) + (2x^2-5y + 3) A) -4x^2 + 3y -2 B) -4x^2 - 3y - 2 C) -4x^2 + 3y +2 D) -4x^2 -3y +2

Rasek [7]

Combine like terms

-6x^2+2y + -1 +2x^2 + -5y +3

( -6x^2+2x^2)+(2y-5y)+(-1+3)

= -4x^2+3y+2

Answer : C

I hope that's help !

Convert to exponential form: log 1000=3

Luden [163]

$\log_a b=c \hbox{ if } a^c=b \\ \\
\log 1000=3 \\
\log_{10} 1000=3 \\
\Downarrow \\
\boxed{10^3=1000}
