Answer:
(-1, -2) or x=-1 y=-2
Step-by-step explanation:
3x+y=-4 (1)
3x-4y=6 (2)
i used the first equation to subtract the second this cancels out the x
and you are left with:
5y=-10
y=-2
plug this back in:
2x+(-2)=-4
2x-2=-4
add 2 to both sides:
2x=-2
x=-1

formula for rengtangular solid(Prism):L*W*H
Answer:
<u>C. The solution set is {x|x < 6}.</u>
Step-by-step explanation:
<u>Given</u> :
<u>Subtract 4 from both sides.</u>
- 7x + 4 - 4 < 46 - 4
- 7x < 42
<u>Divide 7 from both sides.</u>
<u>C. The solution set is {x|x < 6}.</u>
<u>Answer</u>:
The discriminant of 3 x squared minus 10 x = negative 2 is 76
<u>Explanation</u>:
<u>Given</u>:
..........(1)
We can find out the discriminant by using the formula
So from the equation (1)
We have b = -10
a= 3
c= 2
Now put all these values of a,b and c in the formula of discriminant to find out the value of D
So
D=76
So the discriminant of the given quadritic equation = 76
Answer:In this question, you are given a number in the standard form and asked to convert it into expanded form. In expanded form, you need to expand it to every digit that has value(all that wasn't 0).
