2(9x-1)+7(x+6)=-60
Reorder the terms in parentheses
+(+18x-2)+7*(x+6)=-60
Remove unnecessary parentheses
+18x-2+7*(+x+6)=-60
Reorder the terms in parentheses
+18x-2+(+7x+42)=-60
Remove unnecessary parentheses
+18x-2+7x+42=-60
We move all terms containing x to the left and all other terms to the right
+18x+7x=-60+2-42
We simplify left and right side of the equation
+25x=-100
We divide both sides of the equation by 25 to get x
x=-100/25
x=-4
Answer:
144
Step-by-step explanation:
The best way to attempt this question is to solve it using a Venn diagram
From the given information, Let;
D = documentaries
I = interview shows
G = game show reruns
From the images attached below, we will see how the Venn diagrams are being drawn step by step and calculated.
i.e
= 300 - (90 + 60 + 24 + 6 + 12 + 18 + 24)
= 300 - 234
= 66
∴
No of those interested in exactly one kind of show = 66 + 60 + 18
= 144
∴
<span>The first choice is correct.
Explanation<span>:
The formula for slope is m=(y</span></span>₂<span><span>-y</span></span>₁<span><span>)/(x</span></span>₂<span><span>-x</span></span>₁<span><span>). Once we find the slope using that formula, it goes in place of m in y=mx+b.
We do not yet have the y-intercept, but we can use one of the points to find it. We substitute the x-coordinate of one point in for x and the y-coordinate of the same point in for y; then we solve for b. This gives us the y-intercept.</span></span>
