Answer:

x=15

Step-by-step explanation:

These angles are corresponding angles and with parallel lines corresponding angles are equal

9x+19 = 10x+4

Subtract 9x from each side

9x+19 -9x = 10x+4-9x

19 = x+4

Subtract 9 from each side

19-4 =x

15=x

Help! I have looked at so many lessons on writing exponential functions from a graph and nothing has helped.
Over [174]

Answer:

y = 8(-\frac{1}{2})^x

Step-by-step explanation:

Let the equation of the exponential function is,

y = a(b)ˣ

Since the graph of this function passes through two points (4, \frac{1}{2}) and (3, -1)

For the point (4, \frac{1}{2}),

\frac{1}{2}=a(b)^4 ---------(1)

For second point (3, -1),

-1 = a(b)³ ---------(2)

Divide equation (2) by equation (1),

\frac{\frac{1}{2}}{-1} = \frac{a(b)^4}{a(b)^3}

-\frac{1}{2}=b^{(4-3)}

-\frac{1}{2}=b

From equation (2)

-1 = a(-\frac{1}{2})^3

-1 = -\frac{1}{8}a

a = 8

Therefore, equation of the exponential function will be,

y = 8(-\frac{1}{2})^x

Polygon a is similar to polygon b. the sides of polygon a are three times larger than the corresponding sides of polygon b. the
JulsSmile [24]

Answer:

b 48

Step-by-step explanation:

it says the sides a are 3 times larger so you are trying to find the perimeter of b so you do 144 divided by 3 since it is 3 times larger.

Identify the segment bisector of MN Then find MN.<br> ????????? Helppp pleaseee
enot [183]

Given:

The figure.

To find:

The segment bisector of MN and value of MN.

Solution:

From the given figure it is clear that ray RP,i.e., \overrightarrow {RP} is the segment bisector of MN because it divides segment MN in two equal parts.

Now,

3\dfrac{5}{6}=\dfrac{3\times 6+5}{6}

3\dfrac{5}{6}=\dfrac{23}{6}

Since, \overrightarrow {RP} is the segment bisector of MN, therefore,

MN=2\times \dfrac{23}{6}

MN=\dfrac{23}{3}

MN=7\dfrac{2}{3}

Therefore, the length of MN is 7\dfrac{2}{3}.

Solve this system of equations.
nata0808 [166]

x = 8, y = 0

y=\frac{1}{2}x-4

y=-\frac{1}{4}x+2

We substitute y=\frac{1}{2}x-4 into the y for y=-\frac{1}{4}x+2, and we get:

\frac{1}{2}x-4 = -\frac{1}{4}x+2

+\frac{1}{4}x   +\frac{1}{4}x

\frac{3}{4}x -4 = 2

  +4  +4

\frac{3}{4}x = 6

(4)\frac{3}{4}x = 6 (4)

The 4's cross out and we get:

3x = 24

/3     /3

x=8

Not we substitute x(8) into one of our original equations: y=\frac{1}{2}x-4

y=\frac{1}{2}x-4

y=\frac{1}{2}(8)-4

y=4-4

y-0

We get our final answer: (8,0)

Hope that helps!
