Answer:

There will be No solution for the equation $9x - 4 = - 3x + 5 + 12x$ . Option B is correct.

Step-by-step explanation:

We need to determine how many solutions the equation $9x - 4 = - 3x + 5 + 12x$ have.

Solving the equation and finding the solutions

$9x - 4 = - 3x + 5 + 12x$

Combining like terms, Moving 3x and 12x to left side of equality and changing their signs and moving 4 on right side of equation and changing sign.

$9x +3x-12x = 5 + 4$

Simplifying

$12x-12x = 9\\0=9$

Solving the equation we get 0=9 which is false. So, there will be No solution for the equation $9x - 4 = - 3x + 5 + 12x$ . Option B is correct.

Select the least common multiple of 12 and 15. A. 3 B. 15 C. 60 D. 180

ad-work [718]

Answer:

Step-by-step explanation:

12=2⋅2⋅3

15=3⋅5

We see that they both share 3 is their LCM.

We divide each number by their LCM.

123⇒4

153⇒5

We multiply these two quotients and the LCM to get our final answer:

3⋅4⋅5=60

That is our answer!

Hope this helped! :)

Consider the parabola y = 8x − x2. (a) find the slope of the tangent line to the parabola at the point (1, 7). 6 (b) find an equ

Brut [27]

In order to find any of the info we need we have to find the first derivative of the equation. If $y=-x^2+8x$ , then $y'=-2x+8$ . We are told to find the slope at point (1, 7). Using that x value in our derivative will give us the slope of the line at that point. y' = -(1)^2+8. So y' = 7. That's the slope of the line. Now we will use that slope along with the x and y coordinate in the slope-intercept form of a line to solve for b. 7 = 7(1) + b so b = 0. Our equation then is y = 7x. If you graph these in the same window on your calculator, you can see how perfectly that align at the given point. It's really quite perfect.

luke jogged a total of 56.5 miles last week. if luke jogged the same distance,d, each day for 3 days and half that distance on e

Leokris [45]

The algebraic equation used to answer this question is:
3d + 4(1/2d) = 56.5
This is because he ran d, the distance, three times that week. For the rest of the four days, he ran 1/2 the distance, or half d.
To find the answer, you first distribute:
3d + 2d = 56.5
Add like terms:
5d = 56.5
Divide both side by 5:
5d/5 = 56.5/5
d = 11.3
On the first three days, Luke jogged 11.3 miles. On the remaining days, where he jogged 1/2d, Luke jogged 5.65 miles.
Hope this helps!

What can you say about the quotient, when you divide 23 by something equal to 1?

Gwar [14]

Answer: the quotient will be equal to 23

The equation to calculate what divided by 23 equals 1 is as follows:

X/23 = 1

Where X is the answer. When we solve the equation by multiplying each side by 23, you get get:

X = 23

Therefore, the answer to what divided by 23 equals 1 is 23

so the quotient will be equal to 23
