Answer:

x=6.4

Step-by-step explanation:

-19+3x-11+2x

=(3x+2x)-(11+19)

=5x-30

so

5x-30=2

5x=32

x=32/5

To make this easy I'll multiply the fraction by 2

x=64/10

x=6.4

find real numbers a, b, and c so that the graph of the function y=ax^2+c contains the points (-1,6), (2,7), and (0,1)
Paraphin [41]
This gives you three simultaneous equations:

6 = a + c
7 = 4a + c
1 = c
 
<u>c = 1
</u>
<u /><u />
If c =1,

6 = a + 1
<u>a = 5
</u>
<u /><u />
This doesn't work in the second equation, so the quadratic that goes through these points is not in the form y = ax^2 + bx + c
Was there supposed to be a b in the equation?

The base of a triangular garden measures 5.5 feet. It takes 33 pounds of mulch to cover the garden. If 4 pounds of mulch are nee
Stells [14]
The dimensions given when you have a triangle is the base and height of the triangle. The formula for the area is

A = 0.5bh

The unknown here is h. We can determine that from the cost of mulch that covers the whole area of the triangle. The equation would be:

4A = 33

Substituting A = 0.5*5.5*h = 2.75h to the equation:

4(2.75h) = 33
11h = 33
h = 33/11
h = 3 feet

My name is Ann [436]
Switch sides

4/5 (x+3)=y+6

Multiply both sides by 5

5*4/5 (x+3) = 5y+5*6

Simplify

4(x+3) = 57+30

Divide both sides by 4

4(x+3)/4 = 5y/4+ 30/4

Simplify

x+3 = 5y+30/4 

Subtract 3 from both sides

x+3 - 3 = 5y+30/4 - 3

Simplify 

x=5y+30/4 - 3

Solve for x: negative 3 over 2, multiplied by x minus 9 equals negative 27 −24 −12 11 12 Btw please show the work bc i not only
Firdavs [7]

Answer:

\boxed{ x = 12}

Step-by-step explanation:

<u>Given Equation is:</u>

\frac{-3}{2} (x) - 9 = -27

Adding 9 to both sides

=> \frac{-3x}{2} = -27+9

=> \frac{-3x}{2} = -18

Multiplying 2 to both sides

=> -3x = -18 * 2

=> -3x = -36

Dividing both sides by -3

=> x = 12
