1 answer:
inna [77]3 years ago
7 0

Answer:

Step 1 is wrong

Step-by-step explanation:

\frac{1}{4} r+ 2 = 10

\frac{r}{4}  + 2 = 10

\frac{r}{4}  = 10  -  2

\frac{r}{4}  = 8

r = 8 \times 2

r = 32

Solve for y hdgkgsydkydutskgxtisit
Feliz [49]

You said  X = (5y+1) / (y-2)

Multiply each side by (y-2):

X(y-2) = (5y+1)

Eliminate parentheses:

Xy - 2X = 5y + 1

Add  2X  to each side:

Xy = 5y + 1 + 2X

Subtract  5y  from each side:

(X-5)y = 1 + 2X

Divide each side by  (X-5):

<em>y = (1+2X) / (X-5)  </em>

A quadratic function passes through the points ( − 5 , − 8 ) and ( 8 , − 8 ) . Find the equation for the line (axis) of symmetry
ra1l [238]

Answer:

The equation for the axis of symmetry is x=1.5.

Step-by-step explanation:

It is given that a quadratic function passes through the points ( − 5 , − 8 ) and ( 8 , − 8 ) .

In the given points y-coordinates are same, i.e., -8. It means both the points lie on the horizontal line y=-8.

If a quadratic function passes through two points (a,c) and (b,c), then the equation for the axis of symmetry is

x=\frac{a+b}{2}

According to the given points a=-5, b=8 and c=-8. Put these value in the above formula.

x=\frac{-5+8}{2}

x=\frac{3}{2}

x=1.5

Therefore the equation for the axis of symmetry is x=1.5.

A rectangular sand box has a length of 5 1/3 feet and a width of 3 3/4 feet. What is the perimeter in mixed number?
Vadim26 [7]

Answer: 18 1/6 feet

Step-by-step explanation:

From the question, we are informed that the rectangular sand box has a length of 5 1/3 feet and a width of 3 3/4 feet.

The perimeter would be calculated as:

= 2(length + width)

= 2( 5 1/3 + 3 3/4)

= 2( 5 4/12 + 3 9/12)

= 2( 8 13/12)

= 2 (9 1/12)

= 2 × 9 1/12

= 2 × 109/12

= 218/12

= 18 2/12

= 18 1/6 feet
