Answer:
4 solutions
Step-by-step explanation:
if the equation is 2x^4 -3x^3 -24x^2 +13x +12 = 0 you look at the highest degree to find how many solutions. the degree being the highest exponent. so in this case it would be the exponent that is 4 so there should be 4 solutions.
Due to its subject-specific classification, ink color in pens is a qualitative variable.
<h2>What is a Qualitative variable?</h2>
- The factors that cannot be measured with a numerical value are known as qualitative variables.
- In order to define anything, these quantities are not quantified or tallied; instead, data is categorized.
- There is no numerical way to express it.
<h3>Quantitative variable</h3>
- The other choices are erroneous because the variables that are numerically specified in the other choices—an individual's weight, the number of children, and the number of miles—are these.
- Therefore, all of those are quantitative variables.
Consequently, option (C) is the appropriate choice.

Ok so if you notice every choice is solved for a, all you have to do is isolate "a" in 7a-8b=10x. Start by moving 8b to the other side and to change the sign. Now it is 7a = 10x + 8b. Then divide everything by 7 and you get a = (10x + 8b)/7
2w + 2L = 100
2w = L - 8
L - 8 + 2L = 100
3L = 108
L = 36
2w = L - 8
2w = 36 - 8
2w = 28
w = 14
Length is 36, Width is 14
Answer: C) No solution
Let’s solve this. First we need to put the first equation into y=mx+b form. Let’s do this now.
First equation-
2•4y=10
*subtract 2*
4y=8
*divide 4*
y=2
Now that we know the value of y, let’s substitute that into the second equation.
2•4y= -10
2•4(2)= -10
2•8= -10
16= -10
When solved, these equations produce a result where both sides do not equal each other. 16 does not equal -10, making this have no solution.
This is your answer! Hope this helps comment below for more questions :)
