Find the difference: <br> 2(x-2) - 3(x-4)

cluponka [151]

Answer:

brainliest plzzzzz

Step-by-step explanation:

2(x-2) - 3(x-4)

Simplify:

2(x-2)-3(x-4)

2x-4-3(x-4)

Distribute:

2x-4-3(x-4)

2x-4-3x+12

Add the numbers:

2x-4-3x+12

2x+8-3x

Combine like terms:

2x+8-3x

-x+8

Hence Solution = -x+8

Write the equation of the circle centered at ( 7 , − 5 ) (7,-5) with diameter 16

galina1969 [7]

The equation of a circle is (x - h)² + (y - k)² = radius² where (h, k) is the center.

If the diameter is 16, then the radius is 8.

Your equation is:
(x - 7)² + (y + 5)² = 64

If angle LMPis 11 degrees more than angle NMP and angle NML is 137 find each measure.

OLEGan [10]

Answer:

angle NMP = 63°

angle LMP = 74°

Step-by-step explanation:

Let angle NMP be x° . It's given that angle LMP is 11° more than angle NMP. So, angle LMP = x° + 11°

But angle NML = 137°.

So,

angle NMP + angle LMP = 137°

=> x° + x° + 11° = 137°

=> 2x° + 11° = 137°

=> 2x° = 137° - 11°

= 126°

=> x° = 126/2 = 63°

angle NMP = 63°

angle LMP = 63 + 11 = 74°

Hello! Could you please help with these? It was due quite a long time ago. I have a D in this class and need to get my grades up

Digiron [165]

Answer:

16. $y=7x$

17. $y=0.5x$

18. $y=3x$

19. $y=2x$

Step-by-step explanation:

Equation is $y=kx$ where k is a constant of proportionality.

16.

$\frac{y}{x}=\frac{10.5}{1.5}=\frac{14}{2}=\frac{24.5}{3.5}=\frac{35}{5}=7$

So, equation is $y=7x$

17.

$\frac{y}{x}=\frac{1}{2}=\frac{2}{4}=\frac{2.5}{5}=\frac{3.5}{7}=\frac{1}{2}=0.5$

Equation is $y=0.5x$

18.

$\frac{y}{x}=\frac{6}{2}=\frac{9}{3}=\frac{15}{5}=\frac{18}{6}=3$

Equation is $y=3x$

19.

$\frac{y}{x}=\frac{4}{2}=\frac{8}{4}=\frac{14}{7}=\frac{18}{9}=2$

Equation is $y=2x$

A null hypothesis is being tested. How does the confidence level affect the testing process?

xxTIMURxx [149]

<span>If you have a high confidence level, the chance of rejecting the null hypothesis is rare. If you have a low confidence level, the chance of of rejecting the null hypothesis is nonexistent. If you have a low confidence level, the chance of of rejecting the null hypothesis is rare. If you have a high confidence level, the chance of of rejecting the null hypothesis is high.</span>
