Answer:
-5
Step-by-step explanation:
-2x+7>17
-2x>17-7
-2x>10
Divide both sides by -2
-2x<10
-2 -2
x<-5
Note:when dividing with a negative the signs changes
Answer:
37
Step-by-step explanation:
-3x^{2} + 1
replace (x) with (-2)
-3(-2)^{2} + 1
6^2 +1=36+1
=37
Answer:
c
Step-by-step explanation:
c. j = a + 5
such that 7 = 2 +5
Answer:
The answer would be Choice F; (-3,7)
Step-by-step explanation:
- Plot the two guaranteed given points
- A, (-3,2) and C, (2,7)
- Find the point where the x and y would share and then form a right angle. This is called being Perpendicular.
- So, take the <em>x</em> of A, and the <em>y</em> of C and you have the coordinates of B.
(-3,7)
Answer:
32
Step-by-step explanation:
n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)
Given n(A)= ? we represent with x
n(B)= 16
n(A∪B) = 32
Substituting in equation 1 to get n(A)
32 = n(A) + 9 − 9
⇒n(A) = 32 − 0
n(A) = 32
to confirm this we put the values into the formula below
n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)
32 = 32 + 9 - 9
