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

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.

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

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.

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 = 28
