Answer:
JH = 15
Step-by-step explanation:
KJ = 10
KI = 14
IH = 11
JH = ?
In order to find JH, we need to find JI, then add it to IH, which is 11. Here's the equation:
JH = JI + 11
In order to find JI, we need to subtract KJ from KI. Here's the equation:
14(KI) - 10(KJ) = JI
14 - 10 = 4
JI = 4
Now we plug in the numbers from our first equation:
JH = JI + 11
JH = 4 + 11
JH = 15
Answer:
JH= 15Step-by-step explanation:
Let KJ= 10, KI= 14, and IH= 11KI - KJ = J14 - 10 = 4J + IH = JH4 + 11 = 15[tex]\tt{ \green{P} \orange{s} \red{y} \blue{x} \pink{c} \purple{h} \green{i} e}[/tex]
Can someone please help me? I just need these question for finish my test.
Answer:
A. y = |x - 5| - 4
Step-by-step explanation:
The shape of the graph is a V with slope 1 on the right side and slope -1 on the left side. The parent function is y = |x|. The vertex of the V in the parent function is at (0, 0). Here, there has been a translation of the vertex to (5, -4).
The x-coordinate shifted 5 units right, or a shift of +5, and the y-coordinate shifted 4 units down, or a shift of -4.
y - k = |x - h| shows a shift of h units in x and k units in y when compared to the parent function y = |x|.
y - (-4) = |x - 5|
y + 4 = |x - 5|
y = |x - 5| - 4
Answer: A. y = |x - 5| - 4

Evaluate the root without using a calculator, or note that the root isn't a real number.
9514 1404 393
Answer:
A. 2
Step-by-step explanation:
When you don't know if a number like 256 is a power of anything, it can work reasonably well to start by simply dividing by the factors you know.
256/2 = 128128/2 = 6464/2 = 3232/2 = 1616 = 2^4, so 256 = 2^4 · 2 · 2 · 2 · 2 = 2^8The 8th root of 2^8 is 2, choice A.

Which of the following is equal to the rational expression when x ≠ -1 or -7?
(X+1)(x-1)
——————
(X+7)(x+1)
A. x+1
——
x+7
B. x+7
———
x-1
C. x-1
——
x+7
9514 1404 393
Answer:
C. (x -1)/(x +7)
Step-by-step explanation:
The factor (x +1) in the numerator cancels the same factor in the denominator, leaving the ratio (x -1)/(x +7). This matches choice C.
_____
Additional comment
Even though (x+1)/(x+1) = 1 and can be removed from the expression, the fact that it is undefined at x=-1 means the reduced ratio (x-1)/(x+7) is only a valid representation of the original ratio when x≠-1. The factor (x+1) may be gone, but the domain restriction associated with it remains.

Stanley analyzes the table of values for a polynomial function. He has determined through applying Descartes’ rule of sign that there is 1 negative real zero, and either 1 or 3 positive real zeros. He has also determined that the upper bound of the function is 3.
X , f(x)
-2, -105
-1, 0
0, 5
1, -2
2, 3
3, -20
4, -175
a. What is the degree of the polynomial function? How can you tell?
b. How many positive real zeros does the function have? How can you tell?
9514 1404 393
Answer:
a) 4
b) 3
Step-by-step explanation:
a. The total number of real and complex zeros is equal to the degree of the polynomial. That total is (1 negative real) + (3 positive real/complex) = 4 total zeros. The degree of the polynomial is 4.
The even degree is confirmed by the answer to part b, and by the end-behavior shown in the table, which has a tendency to -∞ for |x|→∞.
__
b. The intermediate value theorem tells you there will be zeros in the intervals (0, 1), (1, 2), and (2, 3) according to the values in the table. (The function changes sign in those intervals.) Thus there are 3 positive real zeros.
_____
Additional comment
Stanley cannot tell anything about Descartes' rule of signs by analyzing the table of function values. To use that rule, he must have terms of the polynomial. If he has those terms, he already knows the degree of the polynomial.

what is the slop of 2x+3y-9=0
Answer:
Step-by-step explanation:
We need to write this equation in y=mx+b where m is the slope.
3y= -2x +9
y= -2/3 +9
So now that it is in the form of y=mx+b, we can find the slope. -2/3 is the slope of the equation. Hope that helps!

Explain how you know that the sums of 12.6,3.1 and 5.4 is greater than 20
Answer:
2.6+3.1+5.4 =21.1
if you have 20
subtract 21.1-20
then you have 1.1
since the difference is 1.1 then we say
21.1>20
You take a package to your local shipping company. They charge a fixed base cost of 6 per package plus an additional 0.39 per pound If p represents the number of pounds and c is the total cost of shipping your package write the linear equation that represents the relationship between pans c
Answer:
c = 6 + 0.39p or c = 0.39p + 6
Step-by-step explanation:
p = #pounds
c = total cost to ship
cost c = $6 + $0.39p ($6 flat fee + $0.39 per pound)
Answer:
C=0.39P+6
Step-by-step explanation:
0.39 is per pound, 6 is the fixed charge
Can somebody tell me the domain and show me or tell me the work plz.
Answer:
Set the denom to 0 and solve.
x^2 - 16 = 0 --> x = -4,4
This means the vertical asymptote is 4, -4.
Therefor, the domain is for all real numbers that are not 4, -4.
We ignore the top because if the numerator was 0, it's still a number. But if the denom was 0, then it would be impossible (you can't divide by 0). So for all numbers that can go into the denom that aren't 0, is your domain.

The triangle will have the noted sides the same length. It is best if they are marked as having the same length. The names of the same-length segments tell you the a.pex is point Y.
1) Convert the following to decimals:
a) 25% b) 60% c) 72.1%
d) 7%
e) 9.5%
f).66%
25% = 25% : 100% = 0,25 ← the end
60% = 60% : 100% = 0,6 ← the end
72,1% = 72,1% : 100% = 0,721 ← the end
7% = 7% : 100% = 0,07 ← the end
9,5% = 9,5% : 100% = 0,095 ← the end
66% = 66% : 100% = 0,66
What is the least common multiple of 9 and 12? Enter your answer in the box.
Answer:
36
Step-by-step explanation:
Find cos(x) if [tex]\frac{sin^2x-1}{cosx} =-1[/tex].
A -1
B 2
C 1
D 0
(sin²(x) - 1)/cos(x) = -1
-cos²(x)/cos(x) = -1
-cos²(x) = -cos(x)
cos²(x) - cos(x) = 0
cos(x) (cos(x) - 1) = 0
Then it follows that cos(x) = 0 or cos(x) = 1. But if cos(x) = 0, then the original expression on the left side of the equation would be undefined. Then C is the only valid solution.
