Answer:

- 2x² + 7x + 1

Step-by-step explanation:

f(x) - g(x)

= x² + 2x - 6 - (3x² - 5x - 7) ← distribute parenthesis by - 1

= x² + 2x - 6 - 3x² + 5x + 7 ← collect like terms

= - 2x² + 7x + 1

I need help on question 16 &amp; 17! <br> I don’t really understand how to solve it.
Sidana [21]

Answer:

y = 11

x = 8.6

Step-by-step explanation:

The small triangle with 30,32,y looks like right triangle

so according to formula a^2 + b^2 = c^2

so 30^2 + y^2 = 32^2

900 + y^2 = 1024

y^2 = 124 => y = 11

The larger triangle also looks like a right triangle

so according to formula a^2 + b^2 = c^2

(30 + 10)^2 + 22^2 = (32 + x)^2

1600 + 44 = (32 + x)^2

so (x + 32)^2 = 1644

x + 32 = 40.55

x = 40.55 = 32 = 8.55 = 8.6

Jason plotted points on a number line at the four values below.
olga nikolaevna [1]

Answer:

Point 5/3 is the farthest from 0

Step-by-step explanation:

Given

Points: 0.27, -1/4, 1.1, 5/3

Required

The farthest from zero

The first step is to convert all points to decimal;

Points: 0.27, -1/4, 1.1, 5/3

This becomes

Points: 0.27, -0.25, 1.1, 1.67

The next step is to calculate the absolute difference of each point from 0;

The farthest from 0 is the point with highest absolute difference

For 0.27

Absolute Difference = |0.27 - 0| = |0.27| = 0.27

For -0.25

Absolute Difference = |-0.25 - 0| = |-0.25| = 0.25

For 1.1

Absolute Difference = |1.1 - 0| = |1.1| = 1.1

For 1.67

Absolute Difference = |-1.67 - 0| = |-1.67| = 1.67

From the above calculations; point 1.67 or 5/3 is the farthest from 0
