Solve the simultaneous equations:
3a-2b=14
4a+3b=13
Answer:
Step-by-step explanation:
3a-2b=14 multiply by 3
9a - 6b = 42 (1)
4a+3b=13 multiply by 2
8a +6b = 26 (2)
sum up (1) and (2)
17a = 68
a =4
b=-1
Answer:
a = 4 b = -1
Step-by-step explanation:
13 = 4a - 3b (1)
14 = 3a + 2b (2)
(1) x 2
(2) x 3
26 = 8a - 6b (3)
42 = 9a + 6b (4)
(3) + (4)
68 = 17a
68/17 = 17a/17
a = 4
Substitute back in to original equation
14 = 3(4) - 2b
14 = 12 - 2b
14 - 12 = 12 -12 - 2b
2 = -2b
Divide by -2 both sides
b = -1
Check
3(4) - 2(-1)
12 + 2 = 14

What is the remainder when x3+4x2−7x−10 is divided by x+4?
Enter your answer as an integer, like this: 42
Answer:
18
Step-by-step explanation:
If a polynomial f(x) is divided by (x + h) then the remainder is equal to f(- h)
Given
f(x) = x³ + 4x² - 7x - 10 and divided by (x + 4), then the remainder is
f(- 4) = (- 4)³ +4(- 4)² - 7(- 4) - 10 = - 64 + 64 + 28 - 10 = 18
Thus the remainder is 18
In how many ways can 3
person study groups be
selected from a class of 25
students?
There are 2300 ways by which we can select 3 students out of 25 students.
What is Combination?Combinations are selections made by taking some or all of a number of objects, irrespective of their arrangements.
Here total number of Students = 25
Number of selection = 3
Now,
Total number of ways by which we can select 3 out of 25 = ²⁵C₃
= 25!/3!.22!
= 25 X 24 X 23 X 22! / 3X2X1 X 22!
= 13800 / 6
= 2300
Thus, there are 2300 ways by which we can select 3 students out of 25 students.

Solve for the roots in simplest form using the quadratic formula:
4x2 – 12x = -17
Please answer
Step-by-step explanation:
4x² - 12x + 17 = 0
i is an imaginary number and it equals √-1, and you usually put it when the number under the root is negative.
So √-5 = √5i and √-4 = 2i
Three vertices of a rectangle are located at points (-3, 4), (5,-6), and (5, 4). Where is the fourth vertex located?
Answer:
(-3,-6)
Step-by-step explanation:
We know that rectangles are four-sided shapes made up of four parallel lines. Opposite sides are congruent. We can do a quick graph, keeping those criteria in mind, and quickly figure out that the missing point is (-3,-6).

1. What will happen to the current if the voltage is decreased by one half while the
resistance is held constant? State the relationship of voltage and current based
on your answer.
Answer: Current will reduce by half
Step-by-step explanation:
The formula for Current is;
Current = Voltage/ Resistance
Say for instance that Voltage is 5 volts and Resistance is 2 ohms. Current will be;
= 5/2
= 2.5 amps
If Voltage is decreased by one half to 2.5 while resistance is held constant, current becomes;
= 2.5/2
= 1.25 amps
Current went from 2.5 to 1.25 amps.
This shows that current will reduce by half if the voltage is decreased by one half while the resistance is held constant.

Answer:
B. The graph flips over the x-axis
Step-by-step explanation:
When you plot the coordinate pair (x, y), you plot the point 'y' units above the x-axis. If you change the sign of that (multiply the function by -1), then the point becomes (x, -y), and is plotted 'y' units below the x-axis.
The graph flips over the x-axis.

Attached is an example of a function with its original graph (red) and the graph after being multiplied by -1 (blue). The blue graph is a reflection of the red graph across the x-axis.

Solve 2x + 6 > 20.
O A. x> 13
O B. x>7
O c. x< 13
O D. x<7
Answer:
the answer is x>7
Step-by-step explanation:
The solution of the inequality 2x + 6 > 20 is x<7.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
We have the inequality 2x + 6 > 20.
Now, Subtract 6 from both side we get
2x+ 6 - 6< 20 - 6
2x < 14
Divide both side by 2 we get
2x/2 < 14/2
x< 7

Answer:
D: 2/3x - 13/12 = -5/12x
Step-by-step explanation:
2/3x - 5/6 = -5/12x + 1/4
To simplify, the denominator must be the same. So,
5/6 = 10/12
and 1/4 = 3/12
Then, you move the values to the same side via addition or subtraction.
2/3x (- 10/12 - 3/12) = -5/12x
2/3x - 13/12 = -5/12x
