Younger than = less than

Less than symbol = <

People cannot have a negative age, so a must be positive

B. <span>a < 18 and a must be a positive number</span>

A point is dilated with respect to the origin. Determine the value of K and state whether the dilation is an expansion or contra

vlabodo [156]

Scale Factor (K) = (new length/measure)/ (original length/measure)
for x-coordinate = 8/2 = 4
for y-coordinate = 16/4 = 4

K=4, expansion

K is the representation of "scale factor". Scale factor is the ratio of the lengths involved of the similar figures. It can be used to identify the kind of dilation, whether it is contraction or expansion. If the Scale Factor is greater than 1, then that means expansion and if it is less than 1, then it signifies contraction.

Find the equivalent expression by drawing a line from the left column to the right

Gala2k [10]

Answer/Step-by-step explanation:

$2(3x - 1) = 2*3x 2*-1 = 6x - 2$

$(x*y)2 = (xy)2 = 2xy$

$2(2x - 3) = 2*2x 2*-3 = 4x - 6$

$3x + 4x + 2 = (3x + 4x) + 2 = 7x + 2$

$7x - 7 = 7(x) - 7(1) = 7(x - 1)$

$x(6 + 9) = x(15) = 15x$

$2 + 9x + 1 + 3x = (9x + 3x) + (2 + 1) = 12x + 3$

$4(x + 2) + x = 4x + 8 + x = 4x + x + 8 = 5x + 8$

Graph the system & write its solution <br> 2x+y=-4<br> Y=-1/2x-1

xz_007 [3.2K]

Answer:

The solution of system of equation is (-2,0)

Step-by-step explanation:

Given system of equation are

Equation 1 : 2x+y=(-4)

Equation 2 : y+ $\frac{1}{2}$ x=(-1)

To plot the equation of line, we need at least two points

For Equation 1 : 2x+y=(-4)

Let x=0

2x+y=(-4)

2(0)+y=(-4)

y=(-4)

Let x=1

2x+y=(-4)

2(1)+y=(-4)

y=(-6)

Therefore,

The required points for equation is (0,-4) and (1,-6)

For Equation 2 : y+ $\frac{1}{2}$ x=(-1)

Let x=0

y+ $\frac{1}{2}$ x=(-1)

y+ $\frac{1}{2}$ (0)=(-1)

y=(-1)

Let x=2

y+ $\frac{1}{2}$ x=(-1)

y+ $\frac{1}{2}$ (2)=(-1)

y=(-2)

The required points for equation is (0,-1) and (2,-2)

Now, plot the graph using this points

From the graph,

The red line is equation 1 and blue line is equation 2

Since. The point of intersection is solution of system of equations

The solution of system of equation is (-2,0)
