Answer:

-5

Step-by-step explanation:

The given system is

x + 2y = 5 \\ x - 3y = 7

The corresponding coefficient matrix is shown in attachment.

The value of the system determinant, is the determinant of the coefficient matrix.

Which is

On quadrant I ⇒ point F
On quadrant II ⇒ point A
On quadrant III ⇒ point C

Hank has read 25 percent of his book. If Hank has read 150 pages, which equation can be used to find the total number of pages i
oee [108]

Answer:

150=\frac{1}{4} x, or 4(150)=x

Step-by-step explanation:

Let's use x to represent the total number of pages in the book.

If 150 is a quarter of the whole book, then 150 is equal to a quarter of x

150= .25(x)

We an go further and multiply both sides by 4 to cancel the .25

4(150)=x

We can finish solving and x=600 pages

The similarity transformation is a dilation with a scale factor less than 1 and then a reflection

<h3>What is transformation?</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Dilation is the increase or decrease in the size of a figure by a scale factor.

Polygon ABCD is larger than polygon A'B'C'D' and is reflected across the y-axis to form polygon A'B'C'D'

The similarity transformation is a dilation with a scale factor less than 1 and then a reflection

Can someone help me solve this step by step?
patriot [66]

Answer:

41 and 77

Step-by-step explanation:

x: his age the first time he went to space

y: his age the second time he went to space

the second time he went to space he was 5 years younger than twice the age when he went his first time, then:

y = 2x - 5

the sum of both ages is 118, then:

x + y = 118

If you replace y = 2x - 5 in x + y =118:

x + 2x - 5 = 118

3x = 123

x = 41

replacing x:

41 + y = 118

y = 118 - 41

y = 77

so when he was 77, he was 5 years younger than twice 41 ( 41*2 = 82 => 82 - 5 =77)
