What does ( 7.8 x 10 to the 3rd) x (1.0 x 10 to the 4th) equal?

Answers

Answer 1

Answer:

Answer:

7.8 * 10^7

Step-by-step explanation:

Group coefficients together and exponents together to multiply numbers in scientific notation.

(7.8 * 1) (10^3 * 10^4)

Multiply 7.8 times 1.

7.8 * (10^3 * 10^4)

Use the power rule a^m * a^n = a^(m+n) to combine exponents. So, add 3 and 4

7.8 * 10^7

Answers

Answer:

Step-by-step explanation:

-2x + 5y = -15

5x + 2y = -6

-10x + 25y = -75

10x + 10y = -30

35y = -105

y = -3

5x + 2(-3) = -6

5x - 6 = -6

−4
−8

Answers

If you would like to find the coefficient of the variable in the expression 6 - 4x - 8 + 2, you can calculate this using the following step:

6 - 4x - 8 + 2 = 6 - 8 + 2 - 4x = - 4x

The correct result would be - 4.

Answer:

The coefficient is -4

ANSWER

EXPLANATION

In linear functions we often have the slope-intercept form of the equation:

$f(x)=mx+b$

Which can also be written in a different order, for example:

$f(x)=b+mx$

m is the slope of the line. The slope of the graph of a function is the rate of change.

b is the y-intercept. This
