Answer:

ok the slope is -1/2

the points I used where (-6,-1) and (-2,-3)

the intercept of y is -4

the equation is 2y +x+8=0

Step-by-step explanation:

using the formula<u> </u><u>y2-</u><u> </u><u>y1</u><u> </u><u> </u><u> </u><u> </u> = m

X2-X1

where m is the gradient, the slope is found

the original equation is y=-1/2x-4

and so if x is zero ( to get the y intercept)

y=-4

using the formula y - y1= m( x -x1 )

, the equation is determined

Identify all solutions for a triangle with A = 38 degrees b = 10, and a= 8. Round to the nearest tenth.
rjkz [21]

Answer:

A = 38°

B = 50.32°

C = 91.68°

a = 8

b = 10

c = 12.77

Step-by-step explanation:

The first thing is to find the angle B, like this:

sin B = b * sin A / a = 10 * sin (38 °) / 8

sin B = 0.77

B = arc sin (0.77)

B = 50.32 °

For angle C, it would be:

C = 180 - 38 - 50.32

C = 91.68 °

Side c, we calculate it like this:

c = a * sin C / sin A = 8 * sin (91.68 °) / sin (38 °)

c = 12.77

there are 300 student and teachers at a sports event.Grade k to 2 is students: 137 Grade 3 to 5 students: 145 Teachers: ? what i
AVprozaik [17]

Answer:

6%

Percentage of teachers = 6%

Step-by-step explanation:

Given;

Number of grade k-2 students = 137

Number of grade 3-5 students = 145

Total = 300

Number of teachers = 300 - (137+145) = 18

Percentage of teachers = (number of teachers÷total)× 100%

%T = (18/300) × 100

%T = 6%
