Andre says 10x + 6 and 5x + 11 are equivalent because they both equal 16 when x is 1. Do you agree with Andre?​

Answer:

No, They are not equivalent

Step-by-step explanation:

The two expressions are only said to be equivalent if they are the same regardless of whatever value the variable(s) is.

The variable in this question is x.

To prove this, we equate both expressions:

10x + 6 = 5x + 11

10x - 5x = 11 - 6\\\\\\5x = 5\\\\\\x = 1

This shows that they have the same value ONLY when x is 1.

This is why Andre says that they are equivalent, but they are not.

Can anyone help me with this Midterm Advanced Algebra problem. (DONT ANSWER IF YOUR NOT SURE)
tigry1 [53]

Answer:

y = -1/2x + 13/2

Step-by-step explanation:

The slope of a line that is perpendicular to a line will be a negative reciprocal. When you rewrite 2x-7=8 into slope-intercept form, you get y=2x-8. The negative reciprocal of the slope 2x is -1/2x. There is only one option with this slope. If you're still not sure then you can use a graphing calculator to check this. An online one would be desmos

I need to find the slope and y-intercept of this equation. I also need to convert it to slope intercept form. The equation is 3x
USPshnik [31]

Answer:

slope=-1/2

y intercept =-2

Step-by-step explanation:

what u have to do is get y on 1 side and 3x on the other, so take away 3x from both sides which leaves you with 6y = -3x -12. then divide both sides by 6 to get y on it's own so you have y= -1/2x -2. this formula is y=mx+c the m is always the slope and the c is always the y intercept

Select the correct answer. Given the following formula, solve for a. A. B. C. D. <br> s=a+b+C/2
nexus9112 [7]

Hey there!

The answer to your question is a = s - b - C/2

<u>To solve for "a", we must get "a" on it's own side of the equal sign.</u> We can first subtract "s" from both sides:

<em>0 = a + b + C/2 - s</em>

Then, we can subtract a from both sides:

<em>-a = b + C/2 - s</em>

Finally, we divide both sides by -1, so a is by itself.

<em>a = -b - C/2 + s</em>

And we can rearrange it to the standard form:

a = s - b - C/2

Good luck, and hope it helped! Have a great day!
