3(x-7)+8=-20
Multiply the bracket by 3
(3)(x)(3(-7)+8= -20
3x-21+8= -20
3x-13= -20
Move -13 to the other side. Sign changes from -13 to +13.
3x-13+13= -20+13
3x= -7
Divide by 3
3x/3= -7/3
x= -7/3 or in mixed number : -2 1/3
Answer : x= -7/3 or in mixed number : -2 1/3
Answer:
$180
Step-by-step explanation:
$600/$100 = 6
$600 es 6 veces $100.
Por vender $600 gana 6 veces mas que por vender $100.
6 * $30 = $180
Respuesta: $180
Answer:
x=7 y=3
Step-by-step explanation:
-x+6y=11
2x-3y=5
-2x+12y=22
2x-3y=5
Add both equations
-2x+2x-3y+12=22+5
9y=27
y=3
plug y back in
-x+18=11
-x=-7
x=7
The answer will be
-1.8h=-7.2-8.1
h=-15.3/-1.8
h=8.5
Answer:
The one in the table on the left
Note that for the given values of x all of the y values are 2
This indicates a horizontal line, parallel to the x- axis with a slope of zero.
The equation of the line is y = c where c is the value of the y- coordinates the line passes through, in this case 2, thus
y = 2 is the equation of the line with zero slopeation
one of them is an undefined slope the other is a positive slope (Neither of them are a zero slope)
