Answer:

2/3

Step-by-step explanation:

Since triangles ADE and ABC are similar we can calculate the value of x using similarity ratio

AD/AB = ED/CB

3/2 = 1/x cross multiply expressions

3x = 2 divide both sides by 3

x = 2/3

What is the solution to the system of equations below?

katen-ka-za [31]

$4x - y = - 5 \\ - 2x + y = 3$

Solve the second equation for y

$4x - y = - 5 \\ y = 3 + 2x$

Substitute the given value of y into the first equation

$4x - (3 + 2x) = - 5$

Solve the equation for x

$x = - 1$

Substitute the given value of x into the second equation

$y = 3 + 2( - 1)$

Solve the equation for y

$y = 1$

The possible solution of the system is the ordered pair (x,y)

$(x,y) = ( - 1, 1)$

Segment AB has endpoints A(–4, 6) and B(1, 4). After a dilation, centered at the origin, the image of A is (–6, 9). Without meas

Ksivusya [100]

With A and its image one can get the dilation factor;
That is dilation scale factor = -6/-4 or 9/6 = 3/2
Therefore, to get the image of B we multiply the coordinates of B by the dilation factor;
(1,4) 3/2 = (1.5, 6)
Thus the image of B = (1.5,6)

Show that 4x - x? – 7 is always negative. Help

Verizon [17]

Question No 7

Answer:

Please check the explanation.

Step-by-step explanation:

Show that 4x - x² - 7 is always negative.

Given

4x - x² - 7

4x - x² - 7 is always negative because:

-x²-7 will alwas be negative for all the values of x,

The value of - x² - 7 will always be less than 4x for all the values of x

Hence, 4x - x² - 7 is always negative

For example,

let suppose we enter x = 1

$4(1)-1^{2} -7\\=4-1-7\\=4-8\\=-4$

let suppose we enter x = -1

$4(-1)-(-1)^{2} - 7\\= -4 - 1 - 7\\= -12$
