Find 5x − 3y − z if x = −2, y = 2, and z = −3<br><br> −19<br> 19<br> 13<br> −13

Blababa [14]

5x - 3y - z
By hypothesis, x = -2, y = 2 and z = -3.

So you all need to do is replace each letter by its value and do the calculus:

5x - 3y - z = 5*(-2) - 3(2) - (-3)
= -10 - 6 + 3=
=-16 + 3
= -13

So when x = -2, y = 2 and z = -3
5x - 3y - z = -13 (answer d)

Hope this helps! :)

What is the area in terms of pi

svetoff [14.1K]

Answer:

<h2>C = 70π cm</h2><h2>A = 2,450 cm²</h2>

Step-by-step explanation:

The perimeter of the given figure is equal to the circumference of whole circle.

The formula of a circumference of a circle:

$C=\pi d$

d - diameter

We have d = 70 cm. Substitute:

$C=70\pi\ cm$

The area of given figure is equal to the area of rectangle 70cm × 35cm.

(look at the picture).

The area of a rectangle:

$A=(70)(35)=2,450\ cm^2$

Answer:

$\large\boxed{2a+14}$

Step-by-step explanation:

$4(a + 2 ) - 2 (a - 3)\qquad\text{use distributive property:}\ a(b+c)=ab+ac\\\\=4a+8-2a-(-6)\qquad\text{combine like terms}\\\\=(4a-2a)+(8+6)\\\\=2a+14$

point C(4,2) divides the line segment joining points A(2,-1) and B(x,y), such that AC:CB=3.1. what are the coordinates of point

White raven [17]

Answer: $B(x,y)=B(\frac{14}{3},3)$

Step-by-step explanation:

$\frac{4-2}{3} =x-4\\2=3x-12\\14=3x\\\frac{14}{3}=x\\\\\frac{2-(-1)}{3}=y-2\\3=3y-6\\9=3y\\3=y$
