1/2(x+18)=4(2x-6)-9x

Mathematics
1 answer:
exis [7]3 years ago
3 0

Answer:

X=-22

Step-by-step explanation:

1/2(x+18)=4(2x-6)-9x

1/2(x+18)=4(2x)-4(6)-9x

1/2(x+18)=8x-24-9x

1/2(x+18)=-x-24

2*1/2(x+18)=2(-x-24)

x+18 = -2x-48

x+2x+18 = -2x+2x-48

3x+18 = -48

3x+18-18 = -48-18

3x = -66

3x/3 = -66/3

x = -22

igomit [66]

Answer:

4 + (3s/10) gallons

Step-by-step explanation:

Originally, there are 4 gallons. Add that to the expression. Every second, 3/10 gallon are filled. So s times 3/10 equal the total number of gallons added. Add both expressions together to get the answer.

given that BD is both the median and altitude of triangle ABC, congruence postulate SAS is used to prove that triangle ABC is wh
stira [4]

Answer:

Isosceles

Step-by-step explanation:

Consider triangle ABC, BD is the median and the altitude drawn to the side AC. This segment (BD) divide the triangle ABC into two triangles: ABD and CBD.

In these triangles:

  • AD=DC (because BD is the median);
  • ∠ADB=∠CDB=90° (because BD is the altitude);
  • BD is common side.

Thus, by SAS postulate, triangles ABD and CBD are conruent. Congruent triangles have congruent corresponding sides. Hence, AB=CB.

If in triangle ABC, AB=BC, then this triangle is isosceles.

Write the equation of a line that is perpendicular to y =3x-2 and that passes through the point(-9,5)
Oduvanchick [21]

Answer:

y = -1/3x + 8

Step-by-step explanation:

If two lines are perpendicular, the signs of the slope must be opposite and the slopes are reciprocals.

(basically if one is say -2/3, the other is 3/2. just flip it upside down)

So this slope is 3, so the new slope should be -1/3

The equation is now y = -1/3x + b

To find b, substitute (-9,5) in the equation

y = -1/3x + b

5 = -1/3(9) + b

5 = -3 + b

8 = b

So the equation is y = -1/3x + b
