Answer:

On a coordinate plane, a line goes through (0, 3) and (2, 4) and another line goes through (0, 3) and (0.75, 0).

This answer almost coincide with option C. I suppose there was a mistype.

Step-by-step explanation:

The system of equations is formed by:

–x + 2y = 6

4x + y = 3

In the picture attached, the solution set is shown.

The first equation goes through (0, 3) and (2, 4), as can be checked by:

–(0) + 2(3) = 6

–(2) + 2(4) = 6

The second goes through (0, 3) and (0.75, 0), as can be checked by:

4(0) + (3) = 3

4(0.75) + (0) = 3

find an expression for the area of a rectangle of sides 2x+3 and x-1 given that the perimeter is 28cm what is the value of x
Ierofanga [76]

Answer:

4cm

Step-by-step explanation:

Given data

L=(2x+3)

W=(x-1)

P=28cm

A= L*W

A= (2x+3)*(x-1)

open bracket

A= 2x^2-2x+3x-3

collect like terms

A= 2x^2+x-3

P= 2L+2W

P= 2*(2x+3)+2(x-1)

P= 4x+6+2x-2

collect like terms

P= 6x-4

but p= 28

28= 6x-4

28-4= 6x

24= 6x

x= 24/6

x= 4cm

Hence x= 4cm

Rewrite the expression in the form z^n
olga55 [171]

Answer:

{z}^{ \frac{1}{2} }

Step-by-step explanation:

\huge \sqrt[5]{ {z}^{4} {z}^{ -  \frac{3}{2} }  }  \\  \\  =  \huge \sqrt[5]{ {z}^{4 -  \frac{3}{2}  }  } \\  \\  =  \huge \sqrt[5]{ {z}^{ \frac{8 - 3}{2}  }  } \\  \\  =  \huge \sqrt[5]{ {z}^{ \frac{5}{2}  }  }  \\  \\  = \huge   {z}^{ \frac{5}{2}  \times  \frac{1}{5} }  \\  \\ = \huge   {z}^{ \frac{1}{2} }

Sketch a quadratic function with the given characteristics.
xeze [42]

Answer:

See photo below

Add arrows to the two ends of the parabola.

Step-by-step explanation:

To sketch this quadratic function, we to connect three dots: the two roots and a vertex.

The given roots are -1 and 1.

Draw <u>two dots at the x-intercepts</u>, which are (-1, 0) and (1, 0).

Vertex dot: V (x, y)

The vertex x-coordinate always in the middle of the two roots. The middle of -1 and 1 is 0. That's the same as the y-axis.

V (0, y)

Since the function increases when x < 0, the parabola will <u>open up</u>.

We read from left to right. The greater numbers are towards the top of the page.

<u>You can put the vertex anywhere on the y-axis that is below the x-axis.</u>
