Answer:

-4(1-x) 《 -12 +2

-4 + 4x 《 -12 + 2

4x 《 -10 + 4

4x 《 -6

x 《 -1.5

It's the region towards left of the vertical line x = -1.5

The line should be bold because it's included

The sides OP and RO of triangle POR are produced to points S and T respectively. If ∠SPR = 145° and ∠POT = 115° , find ∠PRO

Margarita [4]

Answer:

$\angle PRQ = 80$

Step-by-step explanation:

Given

$\angle SPR = 145^o$

$\angle POT = 115^o$

See attachment

Required

Find $\angle PRO$

First, calculate $\angle RPO$

$\angle RPO + \angle SPR = 180$ --- angle on a straight line

So, we have:

$\angle RPO + 145 = 180$

Collect like terms

$\angle RPO = 180 - 145$

$\angle RPO = 35$

Next, calculate PQR

$\angle POR + \angle POT = 180$

So, we have:

$\angle POR + 115 = 180$

Collect like terms

$\angle POR = 180-115$

$\angle POR = 65$

So, PRO is calculated as:

$\angle PRO + \angle POR + \angle RPO = 180$ --- angles in a triangle

So, we have:

$\angle PRO + 65 + 35= 180$

$\angle PRO + 100= 180$

Collect like terms

$\angle PRO = 180-100$

$\angle PRO = 80$

The slope-intercept form of a linear equation is y = mx + b, where x and y are coordinates of an ordered pair, m is the slope of

Savatey [412]

Divide both sides by x + b to get m by itself. The equation will look like this: m = $\frac{y}{x+b}$

A basketball is thrown upwards. The height f(t), in feet, of the basketball at time t, in seconds, is given by the following fun

Kruka [31]

Answer:

Well I think it is A because domain is the x values.

Step-by-step explanation:

So when you plug this in your calculator (mine is a ti-84 plus ce) you would hit graph. After it graphs it press Zoom, 0 to center it then press 2nd, trace which pulls up parabola menu's. Press 0 and find the left bound, right bound and then press enter which would give you x values of 2.9375 < t< 6

At the same time I don't know if this is right. I never really excelled at parabolas just trying to help.

While playing games on a particular smart phone, 1% of the battery is drained every five minutes of game play. The battery start

Nostrana [21]

Answer:

B(75) represents the percent of battery full after 75 minutes of game play

Step-by-step explanation:

Let m represent the number of minutes of game play. If 1% of the battery is drained every five minutes of game play, then after m minutes of game play $\dfrac{m}{5}\%$ was drained.

The battery starts off at 80% full. After m minutes the battery will have

$B(m)=80-\dfrac{m}{5}$

percent full.

When $m=75$ minutes, then

$B(75)=80-\dfrac{75}{5}=80-15=65\%.$
