the graph below shows a quadratic function f(x) and an absolute value function g(x)
which of the following x-values are approximate solutions to the equation f(x)=g(x)? select all that apply
Answers
Answer:
The x-values that are approximate solution of the equation [tex]f(x) = g(x)[/tex] are [tex]x_{1} \approx -3.5[/tex] and [tex]x_{2}\approx 5[/tex], respectively.
Step-by-step explanation:
From graph we infer that the x-values that represents a solution to the system of equations corresponds to those values of x in which both functions coincide. As we see, there are two x-values for [tex]f(x) = g(x)[/tex], which are described below:
[tex]x_{1} \approx -3.5[/tex] and [tex]x_{2}\approx 5[/tex]
The x-values that are approximate solution of the equation [tex]f(x) = g(x)[/tex] are [tex]x_{1} \approx -3.5[/tex] and [tex]x_{2}\approx 5[/tex], respectively.

Which equation explains the relationship between segment AB and segment A double prime B double prime? coordinate plane with triangle ABC at A negative 3 comma 3, B 1 comma negative 3, and C negative 3 comma negative 3 segment A double prime B double prime = segment AB over 2 segment AB = segment A double prime B double prime over 2 segment AB over segment A double prime B double prime = one half segment A double prime B double prime over segment AB = 2
Answers
Answer:
A. segment A double prime B double prime = segment AB over 2Step-by-step explanation:
Triangle ABC with coordinates of:
A = (-3, 3), B = (1, -3), C = (-3, -3)Translation (x + 2, y + 0), coordinates will be:
A' = (-1, 3), B = ( 3, -3), C = (-1, -3)Dilation by a scale factor of 1/2 from the origin, coordinates will be:
A'' = (-0.5, 1.5), B'' = (1.5, -1.5), C= (-0.5, -1.5)Let's find the length of AB and A''B'' using distance formula
d = √(x2-x1)² + (y2 - y1)²AB = √(1-(-3))² + (-3 -3)² = √4²+6² = √16+36 = √52 = 2√13A''B'' = √(1.5 - (-0.5)) + (-1.5 - 1.5)² = √2²+3² = √13We see that
AB = 2A''B''Now the answer options:
A. segment A double prime B double prime = segment AB over 2
CorrectB. segment AB = segment A double prime B double prime over 2
Incorrect. Should be AB = A''B''*2C. segment AB over segment A double prime B double prime = one half
Incorrect. Should be AB/A''B'' = 2D. segment A double prime B double prime over segment AB = 2
Incorrect. Should be A''B''/AB = 1/2Answer:
A. segment A double prime B double prime = segment AB over 2

4 ice cream cones cost $6. At this rate, how much do 7 ice cream cones cost?

Answers
Answer:
$42
Step-by-step explanation:
Equation: y = 6x
x = number of ice cream cones
y = 6(7) = 42
Hi! I believe your answer is $10.50. If it's $6 for 4 ice cream cones, divide 6 by 4 and you'll get 1.5, or $1.50 per ice cream cone. For 7 ice cream cones, multiply the unit rate ($1.50 per ice cream cone) by 7. The total cost is $10.50. I hope this helps you! Good luck and have a great day. ❤️✨

What should we subtract from 50/29 to get 24
Answers
Answer:
-22.28
Step-by-step explanation:
Let the number to be subtracted from 50/29 to get 24 to be x
So this can be written as : 50/29 - x =24 ----collect like terms as
50/29 - 24 = x
1.72 -24 = x
-22.28 = x
So to check the answer;
50/29 -{x} = 24
50/29 - {- 22.28} = 24
1.72+ 22.28 = 24 ---correct.

Why does multiplying the input of a linear function change
only the slope while multiplying the output changes both the slope and the
y-intercept?
Answers
Answer:
Step-by-step explanation:
If we have a linear function and we multiply the input of the function, we aren't really changing the values of the function, we're changing the rate at which those values are reached.
E.g. if you look at the attached picture, we have [tex]f(x) = 2x[/tex] and [tex]f_2(x) = 4x[/tex], which is just [tex]f(2x)[/tex]. The value when the red line is x = 1 is half that of the value of the blue line when x = 1.
The values of the f(2x) line are reaching the values of f(x) twice as fast, meaning it has a slope of twice as much. However, it still grows through the same intercept.
If you're interested in the calculus behind this, look up the chain rule of derivatives.
However, when you start changing the output of the function, you're changing the entire equation. It's not the same line anymore.

Answers
Answer:
<R = 124°
Step-by-step explanation:
Note that the sum of angles in a triangle is 180degrees. In a triangle RST
Given
∠R=(11x+3)°
∠S=(x+15)°
∠T=(2x+8)°
Required
∠R
First we need to get the value of x;
since <R+<S+<T = 180
11x+3+x+15+2x+8 = 180
11x+x+2x+3+15+8 = 180
14x+26 = 180
14x = 180-26
14x = 154
x = 154/14
x = 11°
get <R
Since <R = 11x+3
<R = 11(11)+3
<R = 121+3
<R = 124°
Hence the measure of <R is 124°

A fruit jucie company includes 1.231 ounce of apple jucie in 6.65- ounces bottel of a mixied fruit jucie. How much of the bottel of mixied fruit jucie is NOT apple jucie? THANK YOU!
Answers
Answer: 81.49% of bottle of mixed fruit juice is NOT apple juice.
Step-by-step explanation:
Quantity of mixed fruit juice = 6.65 ounces
Quantity of apple juice in it = 1.231 ounce
Quantity of mixed fruit juice is NOT apple juice = (6.65-1.231) ounces
= 5.419 ounces
Fraction of bottle is not apple juice = [tex]\dfrac{5.419}{6.65}\approx0.8149=81.49\%[/tex]
Hence, 81.49% of bottle of mixed fruit juice is NOT apple juice.
