Answer:
A. the first one is true because when x = 5, 4x - 1 equals 19. The second inequality doesn't allow for it to equal 19.
B. 9 is the value that makes the equation true. See below for work to show.
Step-by-step explanation:
4x -1 </= 19 is true because it's "less than or equal to" and when you change the x to 5, the answer is exactly 19. 4(5) - 1 = 19. The other sentence is "4x - 1 is less than 19", and that means it can't equal 19 for that sentence to be true.
Math + words = confusion sometimes. Does that make sense?
------------------------------------
Now let's solve
5x + 2 = 47
Subtract 2 from both sides
5x = 45
divide both sides by 5
x = 9

Follow the process of completing the square to solve x2 - 10x + 8 = 0. What is the value of the constant that will be isolated on the right side of the equation in step 3? -8 -12 -32
Answers
Answer:
25
Step-by-step explanation:
Given the expression x^2 - 10x + 8 = 0.
According to completing the square method
Subtract 8 from both sides
x^2 - 10x + 8 - 8 = 0 - 8
x^2 - 10x = -8
Complete the square
Add the square of half of coefficient of x to both sides
Coefficient of x = -10
Half of Coefficient of x = -10/2
Half of Coefficient of x = -5
Square of Half of Coefficient of x = (-5)^2
Square of Half of Coefficient of x = 25
Add (-5)^2 to both sides
x^2 - 10x + (-5)^2 = -8 + (-5)^2
(x-5)^2 = -8 + 25
(x-5)^2 = 17
Hence the required constant that was added is 25

Consider the functions F(x)= x^2+9x and g(x)=1/x.
F(g(-1))is ? , and G(f(1/2))is ? .
Answers
Answer:
a). -8 b). 4/19
Step-by-step explanation:
F(x)= x²+9x g(x)=1/x.
g(-1) = 1/ - 1
= -1
f(-1) = x²+9x
= -1² + 9(-1)
= 1 - 9
= -8
G(f(1/2))
f(1/2) = x²+9x
= 1/2² + 9(1/2)
= 1/4 + 9/2
= 19/4
g (19/4) = 1/x
= 1/19/4
= 4/19
Answer:
1). -8 2). 4/19
Step-by-step explanation:
F(x)= x²+9x g(x)=1/x.
g(-1) = 1/ - 1
= -1
f(-1) = x²+9x
= -1² + 9(-1)
= 1 - 9
= -8
G(f(1/2))
f(1/2) = x²+9x
= 1/2² + 9(1/2)
= 1/4 + 9/2
= 19/4
g (19/4) = 1/x
= 1/19/4
= 4/19

3. Genotypes are Rr or rr. 50/50 chance of getting either one. Phenotype would be red rose if the genotype is Rr, phenotype would be white rose if the genotype is rr.
reply to this answer if you would like instructions for how to fill out the squares.
Step-by-step explanation:
the capital letters have to do with dominant genes. the lower case letters have to do with not dominant genes. if you have Rr, it would be a dominant gene bc the capital takes over. if you have rr it would be not dominant gene bc there are only lower case. if you have RR it would be dominant gene bc there are only capital letters.
TIP; genotype is the formula (RR, Rr, or rr) phenotype is physical characteristic.

Answer:
Step-by-step explanation:
Givens
You have the hypotenuse: 13
You seek the adjacent side: x
You have the angle enclosing the 2: 47 degrees.
The relationship is the Cosine
Solution
Cos(47) = opposite / hypotenuse
Cos(47) = 0.6820 From your calculator
Cos(47) = x / 13 Multiply both sides by 13
13*cos(47) = x
x=8.866

Enter the ratio equivalent to sin (B)
Answers
Answer:
[tex]\boxed {\boxed {\sf sin(B)= \frac {21}{29}}}[/tex]
Step-by-step explanation:
Sine is the ratio of the opposite side to the hypotenuse.
[tex]sin \theta= \frac {opposite}{hypotenuse}[/tex]
We want to find the sine of angle B. The side AC, which measures 21, is opposite angle B.
The side AB, which measures 29, is the hypotenuse because it is the longest side and opposite the right angle.
[tex]opposite= 21\\hypotenuse=29[/tex]
Substitute the values into the formula.
[tex]sinB= \frac {21}{29}[/tex]
This ratio cannot be reduced further, so it is the final answer.
The sine of B is 21/29
