Answer:

x + 4y = 23

- 3x = 12y +1

3y = 10 - x

2x + 6y = 7

for the linear function f, the graph of y=f(x) in the xy-plane passes through the points (0,2) and (9,9). what is the slope of y

Bas_tet [7]

Answer:

$slope = \frac{(y _{2} - y _{1})}{(x _{2} - x _{1})} \\ = \frac{(9 - 2)}{(9 - 0)} \\ = \frac{7}{9} \\ hence \: slope \: is \: \frac{7}{9}$

1=10^0 into logarithmic form

Tatiana [17]

Answer:

$0 = log_{10} 1$

Step-by-step explanation:

Base for the exponent and for the logarithm are the same!

10^0 is the <u>exponential</u> form where 10 is the base and 0 the exponent

$log_{10} 1$ is the l<u>ogarithm</u> form where 10 is the base

To solve $log_{10} 1 =$ ask the question :

To what power should I raise the base 10 to obtain the number 1 ?

The answer to the power 0 therefore

$log_{10} 1 = 0$

$1 = 10^{0} -is-the- exponential -form\\0 = log_{10} 1 - is -the -logarithmic -form$

G(r)=−(r+11)(r+14)

Oduvanchick [21]

Answer:

The zeros are

Larger $r=-11$

Smaller $r=-14$

2)The vertex is (-12.5,-2.25)

Step-by-step explanation:

The given function is:

$g(r)=(r+11)(r+14)$

This function is already in the factored form therefore it is easy to find the zeros,

$(r+11)(r+14)=0$

Either $(r+11)=0$ or $(r+14)=0$

The zeros are $r=-14$ or $r=-11$

b) The expanded form of the given function is:

$g(r)=r^2+25r+154$

We obtain the vertex form by completing the square:

$g(r)=r^2+25r+(\frac{25}{2})^2+154-(\frac{25}{2})^2$

The vertex form is:

$g(r)=(r+\frac{25}{2})^2-(\frac{9}{4}$

Therefore the vertex is (-12.5,-2.25)
