The first step of solving this is to isolate the variable y in the first equation.
3x - y = -2 Subtract -3x from both sides
- y = - 3x - 2 Divide both sides by -1
y = 3x + 2
Now, substitute that y value into the second equation.
2x^{2} - y = 10 Substitute
<span>2x^{2} - (3x + 2) = 10 Multiply all of the numbers in the parentheses by -1
2x^{2} - 3x - 2 = 10
</span>
<span>So the correct answer choice is D) 2x^{2} -3x - 2 = 10.</span>
116 1/4 = 465/4 and 2 2/9 = 20/9
(465/4)÷(20/9) will be the answer and it is equal to 52 flags
Answer:
(2,-4) And (3,-2)
Step-by-step explanation:
Here we have to solve one linear equation and a quadratic equation.
First we find the value of y in terms of x from linear equation and then substitute this value in our quadratic equation to solve it for x , Let us see how :
we have y-2x=8
y=2x-8
Now we substitute this in 
Hence we have
Thus we have
either (x-2)= 0 or (x-3)=0
or x=2 or x=3
Now let us find the value of y by substituting them in y=2x-8 one by one.
y=2(2)-8= 4-8=-4
y+2((3)-8=6-8=-2
Hence our coordinates are
(2,-4) and (3,-2)
Answer: c = 20/10
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
We have to divide the number of carrots (20) by the number of bunnies (10).That expression must be equal to the number of baby carrots that each bunny gets (c)
Mathematically speaking:
c = 20/10
