Answer:
Step-by-step explanation:
x + y = 25
2x - y = 6 Solve for y in this the second equation. Add y to both sides
2x = 6 + y The ys on the left cancel. Subtract 6 from both sides.
2x - 6 = y
Put this value of y into the first equation
x + y = 25
x + 2x - 6 = 25 Combine on the left
3x - 6 = 25 Add 6 to both sides.
3x = 25 + 6 Combine the right
3x = 31 Divide by 3
x = 31 / 3
x = 10.333333
x + y = 25
10.33333 + y = 25 Subtract 10.33333
y = 25 - 10.333333
y = 14.666666
x + y = 25
10.33333 + 14.66666
25 approximately.
2x - y = 6
2*10.33333 - 14.66666
20.66666 - 14.66666
6
You should note that those numbers are repeating decimals
2x - 6 = y

9. Factorize: 6x2 - 19x + 14.
Answer:
Step-by-step explanation:
Here, we want to factor the given polynomial
We have this as;
6x^2 - 19x + 14
= 6x^2 -12x-7x + 14
= 6x(x-2) -7(x-2)
= (6x-7)(x-2)
6x^2-19x + 14 = (6x-7)(x-2)
How many cubic meters of water are required to fill a rectangular swimming pool 15m long and 10 m wide which is 2m deep throughout.How many liters is that?
Answer:
300,000 liters
Step-by-step explanation:
Let us have the measurements in cm
100 cm = 1 m
so the measurements are multiplied by 100
we have this as;
1500 by 1000 by 200
The volume is the product of the 3
This is :
1500 * 1000 * 200 = 300,000,000 cm^3
Mathematically, 1 liter = 1000 cm^3
300,000,000 cm^3 will be ;
300,000,000/1000 = 300,000 liters

graph a line that contains the point (3,-6) and has slope of -1/2
Answer:
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Here, m = slope of the line
b = y intercept
Since, m = -[tex]\frac{1}{2}[/tex]
Equation of the line will be,
y = [tex]-\frac{1}{2}x+b[/tex]
Since, a point (3, -6) lies on the line,
-6 = [tex]-\frac{3}{2}+b[/tex]
b = -6 + 1.5
b = -4.5
Equation of the line will be,
[tex]y=-\frac{x}{2}-\frac{9}{2}[/tex]
Table for the points on the graph,
x -4 -3 -2 -1 0
y -2.5 -3 -3.5 -4 -4.5
Plot these points and join them to get the graph of a line.
HELP The center of a circle is 5 units below the origin, and the radius is 10 units. What is the equation of this circle?
A: x^2 + (y + 5)^2 = 10
B: (x + 5)^2 + y^2 = 10
C: x^2 + (y + 5)^2 = 100
D: (x + 5)^2 + y^2 = 100
Answer:
the answer is c, x^2+(y+5)^2=100.
Step-by-step explanation:
if you go to a graphing calculator and input the equation, you can count the units and see that that’s the right answer.

2/3x-1/5>1 x=?
Answer:
x>9/5
Step-by-step explanation:
2/3x-1/5(+1/5)>1(+1/5)
[add 1/5 on both sides]
2/3x (÷3/2)>6/5 (÷3/2)
[flip 2/3 to 3/2 so that they cancel out]
x>9/5

Answer:11
Step-by-step explanation: think about 5+6 then when you add 11 to the -5 you get 6.
Answer:
The answer is -11.
Step-by-step explanation:
-11 + 6 equals -5.
This is because there is more negative than positive, so -11 would cancel out 6 positive, leaving behind 5 negatives.

PLZZZZ HELP Write 512 as a product of primes use index notation
Answer:
[tex]\mathbf{512 = 2 \times 2 \times 2\times 2\times 2\times 2\times 2\times 2\times 2}[/tex]
Step-by-step explanation:
Prime numbers are those numbers in which they can be divided by itself and 1. They are formed by two natural numbers higher than 1 but not by multiplying natural numbers that are smaller.
So; using index notation to writing 512 as a product of primes; we have:
[tex]\mathbf{512 = 2 \times 2 \times 2\times 2\times 2\times 2\times 2\times 2\times 2}[/tex]
