Answer:
x=12
Step by step explanation:
Step by step explanation:Add 9 to both sides :
15 = 2x - 9
15 + 9 = 2x - 9 + 9
Simplify:
24 = 2x
Divide both sides to get the result:
24 = 2x
24/2 = (2x)/2
Result:
x=12

What is the slope of this line?
Enter your answer as a fraction, formatted like this: 42/53
Or, if the slope is undefined, enter a lowercase letter "u," like this: u
Answer:
-1/2
Step-by-step explanation:
To find the slope, you use the rise/run method.
To get from one point to another, you would move 1 unit down (rise) and 2 units to the right (left)
The slope would be -1/2

Identify the slope and y-intercept of the line y = 9x - 3
Answer:
slope = 9 , y- intercept = - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 9x - 3 ← is in slope- intercept form
with slope m = 9 and y- intercept c = - 3
4x+3y=16 x= -3 and y= -2 Solve the equation

-12-6=16
-18=16
What is the surface area in square inches of a cube with a side 7
inches long?
10
Answer:
28
Step-by-step explanation:
7x4
Answer:
249 inches
Step-by-step explanation:
a cube is equal on all sides so if one side is 7 all sides are 7, if you multiply 7 by 7 you get 49 but that's just one face of the cube, there are 6 faces on a cube so 49 x 6 is 249

the graph of the equation y=2x-1 is shown in the coordinate plane.
wich lists contain only points that lie on the graph of y=2x-1?
A. (0,-1), (15,29), (2,3)
B. (2000, 1999), (3,5)
C. (-2,-3), (-5,-9), (0,0)
D. (-0.5, -2), (0.3, -0.4), (0.5, 0)
E. (1/4, -1/2), (4/5, 3/5)
Answer:
A, D, & E
Step-by-step explanation:
If you plug in the coordinates, they prove to be valid
(0, -1)
2(0) - 1
0 - 1 = -1
(15, 29)
2(15) - 1
30 - 1 = 29
(2, 3)
2(2) - 1
4 - 1 = 3
(-0.5, -2)
2(-0.5) - 1
-1 - 1 = -2
And so on. Just plug them in and see if it is correct.

3. The difference of two-thirds of a number x and
6 is at least -24. Which inequality represents all
possible values for x?
The inequality that represents all possible values for x is x ≥ -27.
What is linear inequality?Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.
Unlike a linear equation it can have a range of values inside an interval.
The given statement can be written in terms of inequality as,
2/3x - 6 ≥ -24
=> 2/3x ≥ -24 + 6
=> 2/3x ≥ -18
=> x ≥ -27
Hence, the inequality expression for the given problem can be written as x ≥ -27.

x2+ 48
x2− 48
x2− 14x + 48
Answer:
x²-14x+48

If x2 + y2 = 14 and xy = 5, find the value of (1/2 x + 1/2 y)2.
Answer:
(½x+½y)²=6
Step-by-step explanation:
x^2 + y^2 = 14, xy=5
(A+B)^2=A^2 +2AB+B^2... (*)
(1/2x+1/2y)^2 =(*)
(1/2x)^2 +2(1/2x)(1/2y)+(1/2y)^2 =
1/4x^2 +1/2xy+1/4y^2=
1/4(x^2 +y^2) +1/2(xy)=
1/4*14+1/2*5=
14/4+5/2=
14/4+10/4=
24/4=6
let me know if I'm wrong.
( 1/2x +1/2y)²
= { ( x + y )/ 2xy }²
= ( x² + 2xy + y² )/4(xy)² —(1)
As we know that x² + y² = 14 — (2)
and xy = 5 —(3)
So, substitute the value of equation 2 and 3 in equation 1,
= ( x² + 2xy + y²)/4(xy)²
=( 14 + 2*5)/(4*5²)
= 24/(4*25)
= 6/25.
