I have an answer and an explanation!
ANSWER:
Explanation:
<span>{Let's solve your equation step-by-step.}
</span>

<span>{Step 1: Factor left side of equation.}
</span>

{<span>Step 2: Set factors equal to 0.}

(4 x 4) - (4/4)
= 16 - 1
= 15
To find the intersecting point, you have to put the two formulas equal to each other
First isolate the same variable, in this case y
So y=x-4
Now we can say
2x + 7 = x - 4
Now solve for x
X= 3
Now fill this in in either one of the formulas
Y= 2 (3) + 7
Y= 13
So they’ll intersect at (3,13)
Hello :
the terme general is : an = a1 +(n-1)d
a11 = a1+(11-1)×5
a11 = -12+50
a11 = 38
<span>the sum of the first 11 terms is : S11 = (11/2)(a1+a11)
</span>S11 = (11/2)(-12+38)
S11 = 143
