Answer:

Algebraically

0.5x-7= √(-5x+29)

(0.5x-7)² = -5x+29

(0.5x)² - 2*0.5x*7 + 7² = -5x+29

0.25x² - 7x + 49 + 5x - 29 = 0

0.25x² - 2x + 20 = 0

Its discriminant is:

b² - 4*a*c

(-2)² - 4*0.25*20

-16 < 0

Therefore, the equation has no solutions.

Graphically

In the picture attached, the plots of the functions are shown. We can see that they don't intersect each other, and that is why there is no solution.

Answer:

Both are correct because after substituting the same value into both expressions, the result is the same.

Step-by-step explanation:

Given the expression:

(1/6)*(6*x + 12) - (1/2)*(4*x + 2)

Applying distributive property:

(1/6)*6*x + (1/6)*12 - (1/2)*4*x - (1/2)*2 =

= x + 2 - 2x - 1 =

= -x + 1

Then, for any number substituted into both equations, the result is the same

Answer:

-3/2,collinear.

Step-by-step explanation:

slope of PQ=(0-3)/(2-0)=-3/2

eq. of line PQ is

y-3=-3/2(x-0)

y-3=-3/2 x

or2y-6=-3x

or 3x+2y=6

if R(4,-3) lies on it,then

3(4)+2(-3)=6

12-6=6

or 6=6

which is true.

Hence points P,Q,R are collinear.

Step-by-step explanation:

Difference of ratio=9-5=4

Sum of ratio=9+5=14

we know that Eric got $56 more

which means

4/14=56

1/14=56/4

1/14=14

1=14*14

=196

now we need to find

9/14=(196*14)/9

      = 239.556

Answer:

3:5 Is the ratio because there are five pieces of cheese.

Step-by-step explanation:

If there are 12 pieces, then you can add 4 and 3 together and get 7 and then you can take 7 from 12 and get 5 which is how many cheese pieces there are. Now you know that there are 3 slices of pepperoni and 5 pieces of cheese. Therefore the ratio is 3:5.

Answer:

x=7

Step-by-step explanation:

48 x=336

x=336/48=7

Chord PY is congruent to Chord NL of a circle with center 0. Option A is correct.

Given,
A circle with center o is shown with two chords equidistant from the center which is 3 units.

The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by

(x - h)² + (y - k)² = r²,
where h, k is the coordinate of the circle's center on the coordinate plane and r is the circle's radius.

Since the property of the circle describes that chords that are equidistant from the center of the circle are equal in length,

In the given question both the given chords are equidistant from the center of the circle i.e 3 units, so the Chord PY is congruent to Chord Nl.

Thus, Chord PY is congruent to Chord NL of the circle with center o. Option A is correct.

Answer: 1 3/5

Step-by-step explanation:

if you have 8 cookies and want to share it with 5 total people you divide it so 8/5 is 1.6

Answer:

y = - 3x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{3}[/tex] x - 3 ← is in slope- intercept form

with slope m = [tex]\frac{1}{3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3 , thus

y = - 3x + c ← is the partial equation

To find c substitute (- 1, - 1) into the partial equation

- 1 = 3 + c ⇒ c = - 1 - 3 = - 4

y = - 3x - 4 ← equation of perpendicular line

Answer:

-3y-3

Step-by-step explanation:

The difference:

For the given set, the average is 13.5 years, and the standard deviation is 17.02 years.

Here we know that the ages of the bears are {5, 4, 6, 39}, then the average of these 4 values is:

[tex]A = \frac{5 + 4 + 6 + 39}{4} = 13.5[/tex]

So the average age of the bears is 13.5 years.

The standard deviation for the given set will be:

[tex]S_X = \sqrt{\frac{(5 - 13.5)^2 + (4 - 13.5)^2 + (6 - 13.5)^2 + (39 - 13.5)^2}{4 - 1} } \\\\S_X = 17.02[/tex]

The standard deviation is 17.02 years.

Answer:

127 1/2 feet

Step-by-step explanation:

A model lighthouse uses a scale of 1/4 inch = 5 feet.

This means that 1/4 inch on the model represents 5 feet in actual life.

The height of the model lighthouse is  6 3/8 inches i.e. 51/8 inches.

The height of the actual lighthouse is:

1/4 inch = 5 feet

51/8 inches = x

Cross-multiply:

51/8 * 5 = 1/4 * x

=> x = 51/8 * 4 * 5

x = 127 1/2 feet

The height of the actual lighthouse is 127 1/2 feet.

Step-by-step explanation:

pythagorean therom 1.6^2+3^2=x^2

Answer:

x = 3.4

Step-by-step explanation:

→You can use the Pythagorean Theorem to solve this:

[tex]a^2+b^2=c^2[/tex]

→The "a," and "b," are the legs, 3 and 1.6, and the "c," is the hypotenuse, which we are trying to find.

[tex]1.6^2+3^2=c^2[/tex]

[tex]2.56 + 9 = c^2[/tex]

→Add like terms (2.56 and 9) together:

[tex]11.56 = c^2[/tex]

→We need to get "c," by itself, and to do this we need to square root both sides, like so:

[tex]\sqrt{11.56} =\sqrt{c^2}[/tex]

[tex]3.4 = c[/tex]
