Arrange the steps in the correct order to perform this subtraction problem. 1.1 × 10^3 – 4.9 × 10^2 PUT THESE IN ORDER please A)

Mariana [72]

Answer:

The correct order is,

A, D, C, F, B, G

Step-by-step explanation:

Given subtraction problem,

A) $1.1\times 10^3-4.9\times 10^2$

Make both significant value with the same exponent of 10,

D) $1.1\times 10^3-\frac{10}{10}4.9\times 10^2$

By solving,

C) $1.1\times 10^3-0.49\times 10^3$ $(a^m.a^n=a^{m+n})$

Taking common $10^3$ from both terms,

F) $(1.1-0.49)10^3$

Subtracting,

B) $0.61\times 10^3$

By solving,

G) $6.1\times 10^2$ ( $0.61 = 6.1\times 10^{-1}$ )

PLEASE HELP ME!!! Thank you SO MUCH! Explain your answer

Answer:

y = -.5x -.5

Step-by-step explanation:

All you do is plug in the x and y in the point to the equation, y = mx + b. Since the coordinate is (5, -3), this in the equation would look like -3 = -.5(5) +b. (all you need to find is the y-intercept, or b.) Solve it out to get -3 = -2.5 + b. Add 2.5 to each side of the equation, you're left with b = -.5. Now, put that back into the original equation, and get y = -.5x -.5. I think this is right, you can go back through and check once more if you'd like.

Ivan used coordinate geometry to prove that quadrilateral EFGH is a square.

Gelneren [198K]

Answer:

(A)Segment EF, segment FG, segment GH, and segment EH are congruent

Step-by-step explanation:

Step 1

Quadrilateral EFGH with points E(-2,3), F(1,6), G(4,3), H(1,0)

Step 2

Using the distance formula

$Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$
