Answer:
{7, -2}
Step-by-step explanation:
6x-7y=2
2x+3y= -10
multiply the second one by -3
6x-7y=2
-6x-9x=30
-16y=32
y= -2
2x - 6 = -10
2x= -4
x= -2
Answer:
False
Step-by-step explanation:
because set of positive factors of 24 is 1,2,3,4,6,8,12,24 and set of positive squares less than 12 is 1,4,9 in which nine does not match
if g(x) is the reflection of f(x) across the x-axis that would mean g(x)= - f(x)
so that would mean you have to change all the signs of f(x) to negative
Ans: g(x)= - x^2 - 3x - 2
Step-by-step answer:
Given:
two inequalities:
4-x <= -1 ........................(1)
2+3x >= 17......................(2)
Required: find the solution of the intersection of inequalities.
Solution:
Solution to (1):
4-x <= -1 transpose
4+1 <=x simplify
5 <= x rewrite
x >= 5
Solution to (2)
2+3x >= 17
3x >= 17-2
3x >= 15
x >= 5
The intersection of the two solutions x>=5 and x>=5 is therefore x>=5
Check:
x=4, => 4-4 = 0 >1 so not a solution
x=4, => 2+3(4) = 14 < 17 so not a solution
x=5, => 4-5 = -1 so a solution
x=5, => 2+3(5) = 17, so a solution.
similarly for 6, 7, ....
I Would Say That The Answer Is (D.)
Because 35 divided by 5 =7
And 100 divided by 5 =20
So the answer is (D.) 7:20
