Answer:

I got x=10

Step-by-step explanation:

Step 1

Everything must add up to 180

180= 6x - 6 + 7x + 1 +55

Step 2

Combine everything

6x + 7x = 13x

-6 + 1 +55 =50

180 = 13x + 50

Step 4

Subtract. 180 -50

130 = 13x

Step 5

Divide 130/13

X=10

6(10) -6 = 54

7(10) + 1=71

Help! Please! Thanks
Illusion [34]

Answer:

C. 3 (t+2)

Step-by-step explanation:

First, for the top fraction, simplify it:

4(t^2-4)/8=4(t+2)(t-2)/8

Now, flip the denominator and multiply the top and bottom fractions:

4(t+2)(t-2)/8 * 6/t-2

You can cancel the (t-2) terms so you get:

4(t+2) *6/8

Reduce the 6/8 to 3/4 so you get:

4(t+2)*3/4

Now cancel the 4's:

3(t+2)  Your answer is C.

Solve for y in the following equation.
Tju [1.3M]

Answer:

y = \frac{z^2 - x}{2}

Step-by-step explanation:

Given:

\sqrt{x + 2y} = z

Required:

Solve for y (make y the subject of the formula)

SOLUTION:

\sqrt{x + 2y} = z

Square both sides

(\sqrt{x + 2y})^2 = z^2

x + 2y = z^2

Subtract both sides by x

2y = z^2 - x

Divide both sides by 2

y = \frac{z^2 - x}{2}

8f(x)=x
victus00 [196]

Answer:

-2 and -4

Step-by-step explanation:

Given the function f(x) = x² + 6x + 8

If f(x) = 0

x² + 6x + 8 = 0

Factorize

x² + 4x + 2x+ 8 = 0

x(x+4)+2(x+4) = 0

(x+2)(x+4) = 0

x+2 = 0 and x+4 = 0

x = -2 and -4

Hence the zero of the function is -2 and -4

A house is built on coordinates (2,9). There is a water pipeline that runs along the line y = 2 3 x – 1. What is the approximate
Basile [38]

Answer:

7.21 units

Step-by-step explanation:

The shortest length needed to connect the house to the existing pipeline is the perpendicular distance between the location of the house (2,9) and the line y = 2/3x - 1.

The perpendicular distance (d) between a point (x_1,y_1) and the line Ax + By + C  = 0 is given as:

d=\frac{|Ax_1+By_1+C|}{\sqrt{A^2+B^2} }

The line is given by y = 2/3 x - 1; 2/3x - y - 1 = 0. The point = (2, 9)

hence A = 2/3, B = -1, C = -1, x_1=2,y_1=9\\. Therefore:

d=\frac{|\frac{2}{3}(2)+(-1)(9)+(-1) |}{\sqrt{\frac{2}{3}^2+(-1)^2 } } \\\\d=7.21
