f(x) = x^2 + 6x - 7

y = x^2 + 6x - 7

y = (x - 1)(x + 7)

x + 7 = 0

x = -7

x - 1 = 0

x = 1

The x-intercepts are -7 and 1.

Since the leading coefficient is a positive, the graph will point upwards.

So, the graph of the function is D.

Solve for x: −2x − 4 > 8

Pavlova-9 [17]

To solve for x in an inequality is very similar to solving for x in an equation since for both you would need to isolate x.

step 1) -2x-4>8 add the 4 over to move any constants over to the +4 +4 other side.
-2x> 12

step 2) x< -6 Divide out the -2 to isolate x, however, keep in mind, when you divide or multiply over any negative number, you must also remember to flip the inquality sign.

Answer: x<-6

tatyana61 [14]

If 7 × 2 = 14, then 14 + 14 = 28. So, 7 times 4 equals to 28. You can add 14 + 14 or multiply 7 and 4 to get your answer.
