ludmilkaskok [199]

Hey!

-------------------------------------------------

This just shows to substitute all of x with -1.

g(-1) = 3(-1) - 5

g(-1) = -3 - 5

g(-1) = -8

-------------------------------------------------

Hence, the answer is -8!

Hope This Helped! Good Luck!

Classify the triangle by its angles.
dedylja [7]

Answer:

29°: Acute 90°: Right 61°: Acute

Step-by-step explanation:

If an angle is less than 90 degrees, it is acute. If it is greater than 90 degrees, it is obtuse. If it is exactly 90 degrees, it is right.

Allie has two cars- a truck and a sedan. Last week, she used 3 gallons of gas in the truck and 5 gallons of gas in the sedan and
gavmur [86]

Answer:

sedan = 26 miles/gallon

truck = 17 miles/gallon

Step-by-step explanation:

try to write the text in mathematical format as a system of equations

t=truck s=sedan

\left \{ {{3t+5s=181} \atop {7t+6s=275}} \right.

first equation can be written as

t= (181-5s)/3

we can use it in the second equation and rewrite it as

7[(181-5s)/3]+6s = 275

7(181/3 -5/3s) + 6s = 275

1267/3 - 35/3s + 6s = 275

-35/3s + 18/3s = 275-1267/3

-35/3s + 18/3s = 825/3 - 1267/3

-35s + 18s = 825 -1267

-17s = -442     s = 442/17 = 26 sedan has an average of 26 miles/gallon

we use this value of s in the first equation

3t + 5*26=181      3t=181-130   t= 51/3 = 17 truck has an average of 17 miles/gallon

PÕQ = 40°? [WAEC] A pie chart is divided into four sectors as shown in Fig. 12.46. Each sector represents a percentage of the wh
Serhud [2]

Answer:

126°

Step-by-step explanation:

the total max percent can be 100%

OR

The total value of the pie is 100%

that means all sectors must add upto 100

=> x + x + 21 + 9 = 100

=> 2x + 30 = 100

=> 2x = 70

=> x = 35

therefore, the two large sectors which are both equal to x each represents 35% of the whole.

<u>Angle subtended by one of those large sectors</u> :-

\theta  =  \frac{component \: part}{total}  \times 360

=  \frac{35}{100}  \times 360 \\  = 126

therfore, the central angle of the big sector is<u> 126°</u>
