Answer: B

For a number to be in correct scientific notation, the first number or the decimal number has to be less than 10. In this case, 75.3 is not less than 10, hence it is the incorrect answer.

Answer: B

Step-by-step explanation:

Scientific notation usually writes as c x 10^n, where c is between 1 and 10. The coefficient of B 75.3 is greater than 10, and also is not in the range of 1 and 10, so b is used scientific notation incorrectly.

What is the equation of a line, in Slope Intercept Form, with a slope of 1/3 and passes through the point (9, 7)?

levacccp [35]

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

We have the slope $m=\dfrac{1}{3}\to y=\dfrac{1}{3}x+b$

and point (9, 7). Substitute:

$7=\dfrac{1}{3}(9)+b$

$7=3+b$ <em>subtract 3 from both sides</em>

$4=b\to b=4$

Answer: $y=\dfrac{1}{3}x+4$

Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

y = x + 8

x + y = 2

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

Substitute in <em>y </em>[2nd Equation]: x + x + 8 = 2
Combine like terms: 2x + 8 = 2
[Subtraction Property of Equality] Subtract 8 on both sides: 2x = -6
[Division Property of Equality] Divide 2 on both sides: x = -3

<u>Step 3: Solve for </u><em><u>y</u></em>

Substitute in <em>x</em> [1st Equation]: y = -3 + 8
Add: y = 5
