Answer:

D. x = -1 and x = 1

General Formulas and Concepts:

Algebra I

Standard Form: ax² + bx + c = 0
Factoring
Solving Roots

Step-by-step explanation:

Step 1: Define

16x² + 9 = 25

Step 2: Solve for x

Subtract 25 on both sides: 16x² - 16 = 0
Factor GCF: 16(x² - 1) = 0
Factor binomial: 16(x - 1)(x + 1) = 0
Find roots: x = -1, 1

After 2 minutes an ant traveled 110 meters and after 7 minutes the ant will have traveled 260 meters. Assuming a linear equation

artcher [175]

Answer: y = 30x + 50

Step-by-step explanation:

let y be the distance traveled (in meters) after x minutes.

If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be

Slope, m = (260 - 110)/(7 - 2)

m = 150/5 = 30

The equation of the straight line can be represented in the slope-intercept form, y = mx + c

Where

c = intercept

m = slope

To determine the intercept, we would substitute x = 7, y = 260 and m = 30 into y = mx + c. It becomes

260 = 30 × 7 + c = 210 + c

c = 260 - 210

c = 50

The linear model becomes

y = 30x + 50
