The first and second numbers have only one option, the third has 2, and the final four have 10 so:
1*1*2*10*10*10*10
1*2*10^4
2*10^4
20000
1.) C - The solution is also -12 because negatives multiplied by negatives cancel each other out.
2.) D - What you did was you chose the answer that looked like where C is. Notice how there is a square root symbol next to the numbers.
4.) C - The square root is 8.3666002534... It would round to 8 and 9.
7.) A - 5 to the third power is 125. (5 x 5 x 5 = 125)
Hope this helped somehow!
1) 125
2) 70
3) 1071
4) 135
Hope this helps! <3
Answer:
infinite solutions
Step-by-step explanation:
Multiply the first equation by 2 so we don't have fractions.
x = 1/2y - 3 becomes 2x = y - 6
Now substitute the second equation into the y-value of the new equation
2x = (2x + 6) - 6
2x = 2x
x can equal anything. this means there are infinite solutions
20) A) p =2(x+3) +2(x+1)
p= 4x +8
B) P= x+4 +x+2 + x+5
p= 3x +11
