Answer:

Last choice.

Step-by-step explanation:

To find the option that is equivalent to this equation, we can begin by narrowing down our options. The slope contains a negative number, meaning the second point must have a lower y value than the first.

Using this criteria, we can eliminate the first and the third answer. Now, we can test the second and fourth answer.

We can test using the slope formula and plugging in values. When the slope formula: $m= \frac{y_{2}-y_{1} }{x_{2} -x_{1} }$

We get a slope of -5 for both of these equations. Let's plug in the point values to check whether they work:

Choice 2:

-24 = -5(4) + 4

-24 = -20 + 4

-24 ≠ -16

Choice 4:

-16 = -5(4) + 4

-16 = -20 + 4

-16 = -16

Therefore, choice 4 is correct!

Make b the subject of the formula<br><br>A=1/2bh

r-ruslan [8.4K]

Answer:

$\blue{b = \dfrac{2A}{h}}$

Step-by-step explanation:

$A = \dfrac{1}{2}bh$

Step 1. Switch sides.

$\dfrac{1}{2}bh = A$

Step 2. Since the fraction 1/2 multiplies b, multiply both sides by the reciprocal of 1/2 which is 2.

$2 \times \dfrac{1}{2}bh = 2 \times A$

$bh = 2A$

Step 3. Since h is multiplying b, and you want b alone, divide both sides by h.

$\dfrac{bh}{h} = \dfrac{2A}{h}$

Answer:

$b = \dfrac{2A}{h}$

8 cubed in standard form and exponential form

masya89 [10]

Answer:

so 8 cubed (8 × 8 × 8) in standard form is: 512

so 8 cubed (8 × 8 × 8) in exponential form is: 8³

Step-by-step explanation:

As we know that

The cube of any given number is that number times itself.

For example, 8 cubed, denoted by 8³ is equal to 8 × 8 × 8.

An exponent basically indicates the number of times we must multiply the base number. For example, to compute 8³, we multiply 3 three times (8×8×8).

so 8 cubed (8 × 8 × 8) in standard form is: 512

so 8 cubed (8 × 8 × 8) in exponential form is: 8³

How do you factor this in the form (x+b)(x+c)

faust18 [17]

So you have your polynomial. To factor this out, you need to find the factors of -45 that will add up to 3. These two factors would be -5 and 8. So, you have factored your polynomial! (x-5)(x+8). If you are still unsure, simply use the FOIL method to check and see if you get the same polynomial back. Hope this helps!
