The equation of a line is given by y = mx + c; where m is the slope.
The given equation is 9 - x = 2y
y = -1/2 x + 9/2
Therefore, the slope is -1/2 and the y-intercept is 9/2.

Write:<br> 3^-4 in standard form

pav-90 [236]

Answer:

$\frac{1}{81}$

Step-by-step explanation:

<u>Key skills: Exponents + Fractions</u>

Use the negative exponent property. If your number is x^-y then it would be the same as 1/x^y

3^-4 is the same as $\frac{1}{3^{4}}$

3^4 is 81, so your answer would be 1/81.

Hope you have a nice day and understood this!

ayme built a box in the shape of a rectangular prism with the dimensions shown. What is the volume of the box, in cubic inches?

Snezhnost [94]

Answer:

$64(in)^{3}$

Step-by-step explanation:

The volume of a box is equal to the length l times the width w times the height h.

$(lenght) \times (width) \times (height)$

Substitute the values of the length l=8, the width w=2, and the height h=4 into the formula.

$8 \times 2 \times 4$

Multiply 8 by 2.

$16 \times 4$

Multiply 16 by 4.

$64 {in}^{3}$

Hence, the volume of the rectangle prism is 64(in)³.
