vladimir1956 [14]

Answer:

16 sq. units

Step-by-step explanation:

<u>The formula for the area of a triangle:</u>

A = 1/2bh

<u>If base and height are known as:</u>

b = 8 units and h = 4 units

<u>Then the area is:</u>

A = 1/2*8*4 = 16 sq. units

Y=-3x+3<br> Y=5x+19<br> Solve this system by substitution

Mars2501 [29]

Answer:

x=-2

Step-by-step explanation:

You can substitute the first equation into the second:

-3x+3=5x+19

Add 3x on both sides:

3=8x+19

Subtract 19 on both sides:

-16=8x

Divide 8 on both sides:

x=-2

______

2.4 9

7.2 28

7 24

8.3 35

3.1 9

7.2 30

9 32

_________

So, the coordinates on the graph (2.4, 9), (7.2, 28), (7, 24), (8.3, 35), (3.1 , 9), ( 7.2, 30), (9, 32).

The first graph represents the line of best fit.

The definition of line of best fit " A line of best fit is a straight line that best represents the data on a scatter plot. This line may pass through some of the points, none of the points, or all of the points.".

<h3>Note: Most of the points should be as closer as possible to the drawn line. </h3>

What is the set of all solutions to the equation \sqrt{x + 2}= {-x} x+2 =−xsquare root of, x, plus, 2, end square root, equals

NARA [144]

Answer:

$x = 2$ or $x = -1$

Step-by-step explanation:

Given

$\sqrt{x + 2}= {-x}$

Required

Find the possible values fo x

$\sqrt{x + 2}= {-x}$

Square both sides

$( \sqrt{x + 2})^2= ({-x})^2$

$x + 2 = x^2$

Equate to 0

$x^2 - x - 2 = 0$

Expand

$x^2 + x -2x - 2 = 0$

Factorize:

$x(x + 1) - 2(x + 1) = 0$

$(x -2)(x +1) = 0$

Split:

$x - 2 = 0$ or $x + 1 = 0$

$x = 2 + 0$ or $x = 0-1$

$x = 2$ or $x = -1$
