Solve the system of linear equations by graphing y = -4x + 2 ; y = -x - 1 What is the solution?

elena-s [515]

Answer:

Step-by-step explanation:

Easiest way would be to substitute points into the given equations and plot your answers.

E.g. if you substitute points into your first equation you get:

If x = 0, y = -4(0) +2 = 2

If x = 1, y = -4(1) +2 = -2

If x = -1, y = -4(-1) +2 = 6

Etc.

Second equation:

If x = 0, y= -(0) -1 = -1

If x = 1, y = -1 -1 = -2

If x = -1, y = -(-1) -1 = 0

Pretty much just plug in values for x into the equations to find y.

Once you have your points, draw a line :)

Where the two lines intercept would be the solution.

Which value of x from the set {4, 5, 6, 7}, makes this equation true? 4(8 − x) = 8

vekshin1

4(8 - x) = 8, 32 - 4x = 8, -4x = -24, So x = 6

The length of ZX is 2 units. What is the perimeter of triangle XYZ?

dezoksy [38]

Keywords

triangle,perimeter,distance, length, side, points

we know that

The perimeter of a triangle is the sum of the three length side

To find the length side calculate the distance between two points

The formula to calculate the distance between to points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

Step 1

Find the distance ZY

$Z(1,0)\\Y(3,1)$

substitute the values

$d=\sqrt{(1-0)^{2}+(3-1)^{2}}$

$dZY=\sqrt{5}\ units$

Step 2

Find the distance XY

$X(-1,4)\\Y(3,1)$

substitute the values

$d=\sqrt{(1-4)^{2}+(3+1)^{2}}$

$dXY=\sqrt{25}=5\ units$

Step 3

Find the perimeter of the triangle

$P=ZX+ZY+XY$

we have

$dZX=2\sqrt{5}\ units$

$dZY=\sqrt{5}\ units$

$dXY=5\ units$

Substitute

$P=(2\sqrt{5}+\sqrt{5}+5)\ units$

therefore

the answer is

$P=(3\sqrt{5}+5)\ units$

5-(-1)÷-2-2=-3/2 I could really use the answer to this.

raketka [301]

Hey there!

$\bold{5-(-1)\div2-2=-\frac{3}{2}}$
$\bold{5-(-1)=5+1=6}$
$\bold{2-2=0}$
$\rightarrow={\bold{\frac{6\div6}{0\div6}=\frac{1}{0}}}$
$\boxed{\boxed{\bold{Answer: FALSE\rightarrow\frac{1}{0}\neq-\frac{3}{2}}}}$ $\checkmark$

Good luck on your assignment and enjoy your day!
