9x+20x+16+12x+10+7x-2=360
48x+24=360
48x=360-24
48 x=336
x=336/48=7

Consider the below equation:
0.5x-7= sqrt(-5x+29)
Give 2 different ways to show that the equation does not have any solutions. One way must be solving algebraically, and the other way must be by graphing.
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.
Write the slope intercept form through (-1, -1), perp to y= 1/3x -3
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

You have found the following ages (in years) of 4 bears. Those bears were randomly selected from the 22 bears at your local zoo: 5,4,6,39 Based on your sample, what is the average age of the bears? What is the standard deviation? Round your answers to the nearest tenth.
Average age: ______ years old
Standard deviation: ______ years
For the given set, the average is 13.5 years, and the standard deviation is 17.02 years.
What is the average age of the bears?
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.
What is the standard deviation?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.

Darren and Quincy wanted to justify that the expression One-sixth (6 x + 12) minus one-half (4 x + 2) is equivalent to Negative x + 1. Their justifications are shown below. Darren’s Method: Substitute 2 into both expressions One-sixth (6 x + 12) minus one-half (4 x + 2) = one-sixth (6 (2) + 12) minus one-half (4 (2) + 2) = one-sixth (24) minus one-half (10) = negative 1. negative x + 1 = (negative 2) + 1 = negative 1 Quincy’s Method: Substitute 6 into both expressions One-sixth (6 x + 12) minus one-half (4 x + 2) = one-sixth (6 (6) + 12) minus one-half (4 (6) + 2) = one-sixth (48) minus one-half (26) = negative 5. negative x + 1 = (negative 6) + 1 = negative 5 Which explains who is correct? Only Darren is correct because he substituted x = 2 into the expressions. Only Quincy is correct because he substituted a number that is the same as the denominator of one of the fractions. Both are correct because after substituting the same value into both expressions, the result is the same. Both are correct because after submitting different values into each expression, the result is the same.
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:
c: Both are correct because after substituting the same value into both expressions, the result is the same.

Two friends, Terrence and Eric share a certain amount of money in the ratio 5:9. If Terrence gets $56 less than Eric find the total amount of money that is shared between the two boys.
Answer:
239.556
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

A model lighthouse uses a scale of 1/4 inch = 5 feet. The height of the model lighthouse is
6 3/8 inches
What is the height of the actual lighthouse?
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.

The set of points P(0, 3), Q(2, 0), R(4, -3) are collinear and the line has a slope of _____.
-3/2
3/2
- 1/2
1/2
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.

fill in the blank. given O below you can conclude that PY is congruent to ______ .
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:
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]
For every 12 slices of pizza sold at Ping's Pizza Shop,
3 slices are pepperoni, 4 are sausage, and the rest are
cheese. What is the ratio of pepperoni to cheese?
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.
