The illustration below shows the graph of y as a function of x.
Complete the following sentences based on the graph of the function.
- As x increases, y _______ (increases/decreases).
- The rate of change for y as a function of x is not __________ (constant/constant), therefore the function is ________ (linear/nonlinear).
- For all values of x, the function value y ___ (≤/≥/=) 0.
- The y-intercept of the graph is the function value y = ____.
- When x = 1, the function value y = ___.
Answer:
As "x" increases "y" *decreases*
y as a function of x is not *constant*
Therefore the function is *nonlinear*
For all values of x, the function value y *≥* 0.
The y intercept of the graph is *8*
x=1 function value of y is *5*

Step-by-step explanation:
h(x)= (x+10)(x+2)
^ It is this way because it is so the x value will equal -10 and -2.
Now, we just distribute it. if the question does not have any points it passes through described in the problem, then it is pretty self explanatory.
x^2 + 2x+ 10x+ 20
= [tex]x^{2} +12x+20[/tex]

Given:
Number of spheres = 2
Number of prisms = 3
Number of pyramids = 5
To find:
The probability that a pyramid will be selected.
Solution:
We have,
Favorable outcomes = Number of pyramids
= 5
Total outcomes = Total number of figures
= [tex]2+3+5[/tex]
= [tex]10[/tex]
Now, the required probability is:
[tex]\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]
[tex]\text{Probability}=\dfrac{5}{10}[/tex]
[tex]\text{Probability}=0.5[/tex]
Therefore, the probability that a pyramid will be selected is 0.5.

Answer: $15.12
Step-by-step explanation:
You just need to find 84% of 18 which is 15.12. what you do is you convert the percent into 0.84 and multiply is by the original price which is 18.
84%=0.84
0.84 times 18 = 15.12

Graph the function f(x)=x^2+4x- 12 on the coordinate plane. (do a, b and c)(explain or show how you know the answer.) (graph down below.)
a) What are the x-intercepts?
(b) What is the y-intercept?
(c) What is the maximum or minimum value?
9514 1404 393
Answer:
a) {-6, 2}
b) -12
c) minimum: -16
Step-by-step explanation:
I find a graphing calculator to be a big help. Its graph is attached.
__
a) The function can be factored as ...
f(x) = (x -2)(x +6)
The factors are zero at the x-intercepts: x = 2, x = -6.
__
b) The y-intercept is the function value when x=0. That is the constant in the function. The y-intercept is -12.
__
c) The leading coefficient of the function is positive, so its graph opens upward. The extreme value is a minimum. It is found on the axis of symmetry, at the x-value that is halfway between the x-intercepts: x = (2-6)/2 = -2. The function value there is ...
f(-2) = (-2-2)(-2+6) = -4(4) = -16
The minimum is f(-2) = -16.
Answer:
I took the test.
A (6, -2)
b (-12)
c Minimum -16

Jan rode to her friend's house with a constant speed of 14 m/hr. How long will she take to
travel the 15 miles there?
Answer:
1.07 hours
Step-by-step explanation:
14 miles = 1 hour
15 miles = x hours
Equal these two together
14 mi/1hr = 15 mi/xhr
Cross multiply
14 mi × x hr = 1 hr × 15 mi
I will stop using the units for now so it won't be as confusing
14x = 15
Divide both sides by 14 to isolate the variable
14x ÷ 14 = 15 ÷ 14
x = 1.07... hours

PLEASE PLEASE PLEASEEEE HELP
Step-by-step explanation:
Volume
= 1/3 * π* r² * h
= 1/3 * 3.14 * 5² * 5
= 1/3 * 3.14 * 25 * 5
= 130.83 units ³
Hope it will help :)❤
Answer:
V = 130.83
Step-by-step explanation:
The equation for the volume of a cone is:
[tex]V =\frac{ \pi r^2h}{3}[/tex]
we can see that r = 5, and h = 5
we will use 3.14 for the value of pi
so, we just fill in the equation with the values we know and solve :)
[tex]V=\frac{\pi r^2h}{3} \\V=\frac{(3.14) (5)^2(5)}{3}\\V=\frac{(3.14) (25)(5)}{3} \\V=\frac{392.5}{3} \\V= 130.8333 (approx.)[/tex]
the question wants the nearest hundred, so the final answer is
V = 130.83

7x-3= -24 what is x and how do you find it?
Answer:
x = -3
Step-by-step explanation:
7x - 3 = -24 (Given)
7x - 3 + 3 = -24 + 3 (Added 3 on both sides by using the addition property of equality)
7x = -21 (Simplified)
7x/7 = -21/7 (Divided 7 on both sides by using the division property of equality)
x = -3 (Simplified)
Therefore, x = -3.
Answer:
x= -3
Step-by-step explanation:
You do the opposite.
So,
-24 +3
= -21
-21/ 7
= -3
Therefore, the answer is -3
HELP PLEASE!! Alita is 2 times as old as Jiro. Jiro is 4 years younger than Erik. Erik is 1/3 as old as dawn. The sum of all their ages is 72 What equation could you write to represent this situtation????
Step-by-step explanation:
72= (e= 1/3d ) + (j= e-4) + (a= 2j)
or
1/3d - 4 × 2 =72
let d = dawn
let e = erik
let j = jiro
let a = alita
remember that a number next to a variable means multiplication.
The equation could write to represent this situation is
72= (e= 1/3d ) + (j= e-4) + (a= 2j)
What is equation?An equation can be defined as a statement that supports the equality of two expressions joined by the equal sign "=". For example, 2x – 5 = 13. These are the expressions 2x – 5 and 13.The sign connecting these two expressions is "=".
In algebra, an equation is a condition of a variable. It will be filled only with the value specified by the variable. This means that the equation 2x – 5 = 13 is satisfied only when x = 9.
Equations are different, for example:
Linear equations Quadratic equations Cubic equations Quartic equations Differential equations Parametric equationsLet us suppose ,
age of Erik is e
dawn is d
Jiro is j
Alita is a
The equation could write to represent this situation is
72= (e= 1/3d ) + (j= e-4) + (a= 2j)

What is a quadratic function that has zeros of x=-1 and x=-2?
Write in factored form.
Answer:
f(x) = (x + 1)(x + 2)
Step-by-step explanation:
Zero x = -1 corresponds to factor x + 1, and zero x = -2 to x + 2. Thus, the quadratic in question is
