Answer:
Answers A and B respectively
Step-by-step explanation:
In the first pic, they are asking you for the value of the function at the points x = -1 and x = 5. Then you are asked to subtract your results. When the value of 'x' is -1, the 'y' value is 3. When the value of 'x' is 5, the 'y' value is -4. Therefore:
[tex]f(-1)-f(5)=3-(-4)=7[/tex]
Answer A
For the second problem, they are saying that the line connecting points A and B is undefined. This means the slope is undefined along that line. An undefined slope is due to a zero in the denominator. Begin by taking the change in 'y' over the change in 'x' to get:
[tex]\frac{y_1-1}{x_1+2} =m[/tex]
In order for our slope 'm' to be undefined, set the denominator to zero and see at what 'x' value this occurs at:
[tex]x_1+2=0[/tex]
[tex]x_1=-2[/tex]
Then they say that the line connecting points C and D is zero. A zero slope would mean a zero in the numerator. Again, begin by taking the change in 'y' over the change in 'x' to get:
[tex]\frac{3-y_2}{-5-x_2} =m[/tex]
Set the numerator equal to zero to get:
[tex]3-y_2=0[/tex]
[tex]y_2=3[/tex]
Answer B

Thirty percent of the beads in a bag are blue. One bead is randomly chosen and replaced. Then a second bead is chosen. What is the probability that neither is blue?
Answers
Answer:
Answer: 12%
Step-by-step explanation:
To find the probability of picking not only a sphere but one that is blue as well, you need to multiply the probabilities of both events because this would show the probability of getting the second event if the first is gotten:
= Probability of sphere * Probability that sphere is blue
= 40% * 30%
= 12%

The first sequence rule is multiply by 4 starting from 7. The second sequence rule is add 5 starting from 8. What is the first number that appears in both sequences?
Answers
Answer: The first number that appears in both sequences is 28.
Step-by-step explanation:
Let's write down numbers from each of the sequences
Sequence 1) We need to start from 7 and multiply 4
7x4=28, 28x4=112
The sequence is 7,28,112...
Sequence 2) We need to start from 8 and add 5
5+8=13, 13+5=18, 18+5=23, 23+5=28
The sequence is 8,13,18,23,28...
They both have 28
28 is the first number that appears in both sequences.
multiply by 4 starting from 7
First sequence: 7 * 4 = 28 *4 = 112 * 4 = 448add 5 starting from 8
Second sequence: 8 + 5 = 13 + 5 = 18 + 5 = 23 + 5 = 28Will give brainlist if possible!!
Solve the system of equations by substitution
Answers
Answer:
x = 4
y = 30
Step-by-step explanation:
Since y = 8x - 2, substitute into 2nd equationThis gives you 3x + 8x - 2 = 42Add 2 to both sides11x = 44Divide both sides by 11x = 4Put this value into either equationI choose the first oney = 8x - 2 = 8 × 4 - 2 = 32 - 2 = 30Answer:
x=4
y=30
Step-by-step explanation:
First re-write the system like this:
[tex] - 8x + y = - 2 \\ 3x + y = 42[/tex]
Now substitute them together:
[tex] - 11x = - 44[/tex]
So
[tex]x = 4[/tex]
put x=4 in one of the equations
[tex]3(4) + y = 42 \\ \\ y = 30[/tex]
so
x=4
y=30

a + 6.6 = 12.6 helpp please !
Answers
Answer:
it is 6
Step-by-step explanation:
because if you subtract 12.6 - 6.6 = 6 so 6 + 6.6 is 12.6
Answer:
A = 6
Step-by-step explanation:
To solve the equation A + 6.6 = 12.6, you need to isolate the variable "A," which represents an unknown value.
Subtract 6.6 from both sides of the equation:
=> A + 6.6 - 6.6 = 12.6 - 6.6
Simplifying this equation gives:
=> A = 6
Therefore, the solution to the equation A + 6.6 = 12.6 is A = 6.

Which is greater: 25% of 15 or 15% of 25? Explain your reasoning using mathematical evidence or visual models.
Answers
15% of 25 is the greatest of the two.
Answer:
25% of 15 is 3.75
15% of 25 is also 3.75
15 - 3.75 = 11.25
25 - 3.75 =21.25
Compare and then determine.
11.25 < 21.25
Answer: 25% x 15=25/100 x 15=.25 x 15=3.75
15% x 25=15/100 x 25=.15 x 25=3.75
Now you can clearly see that they are the same.
