Answer:
Substitution method can be used
Step-by-step explanation:
Given the system of equations
y = 2x-1 ....1
-12x + 3y = 9 ....2
The best method to use id the substitution method
Substitute equation 1 into 2;
From 2;
-12x + 3y = 9
-4x + y = 3
-4x + 2x-1 = 3
-2x -1 = 3
-2x = 3+1
-2X = 4
x = -4/2
x = -2
Substitute x = -2 into 1
y = 2x - 1
y = 2(-2)-1
y = -4-1
y = -5
Hence the solution to the system of equation is (-2, -5)
y=-3/4+6 x intercept
Answer:
y = -3/10 or y = -0.3

what % of $1500 is $1395
Answer:
93%
Step-by-step explanation:
divide 1395 by 1500
0.93
0.93=93%
Answer:
93%
Step-by-step explanation:
This problem can be best solved with a proportion! First, we can set up one side of the proportion with the two values that are given to us. It will look something like this:
[tex]\frac{1395}{1500}[/tex]
Next, we need to set up the other side. Since we are solving for a percent, we know that our x will be out of 100. This side will look something like this:
[tex]\frac{x}{100}[/tex]
Next, we need to set them equal to each other and solve for x.
[tex]\frac{1395}{1500} = \frac{x}{100}[/tex]
To solve, just cross multiply and divide. Multiply 1395 by 100 to get 139,500. Next, divide 139,500 by 1500 to get a final answer of 93%! Hope this helps!

Round 45.983 to the nearest whole number, tenth and hundredth.
Answer:
46
Step-by-step explanation:
if you round to the nearest whole, look at the tenths place and if it is bigger than 4, then then you round up, like 7043.7305 to 7044 but if the tenths place is smaller than 5, the number stays the same but the decimal part is gone, like 350.24569405 to 350.
Sarah and Michelle bought pizza and lemonade for a party.
. Sarah bought 3 pizzas and 2 bottles of lemonade for $31.
• Michelle bought 2 pizzas and 4 bottles of lemonade for $30.
Which of the following systems of equations could be used to find p, the cost of one pizza, and b, the cost of a bottle of lemonade?
A. p + b = 31
p + b = 30
В. Зp + 2b = 30
2p + 4b = 31
C. 3p + 2b = 31
2p + 4b = 30
D. 5p + 6 = 61
p + b= 30
Answer:
C
Step-by-step explanation:
3p + 2b = 31
2p + 4b = 30

The x co-ordinate of any point lying on the Y axis is: please help urgent
Answer:
x-coordinate = 0
Step-by-step explanation:
In a coordinate plan there are two perpendicular lines one is x-axis and another is y-axis
x-axis is a horizontal line and y-axis is a vertical line.
Both lines intersect each other at (0,0).
On x-axis, y-coordinate remains same , i.e., y=0.
On y-axis, x-coordinate remains same , i.e., x=0.
Therefore, the x co-ordinate of any point lying on the y axis is 0.

A number added to 13 all divided by 2
Answer:
[tex]\frac{13+x}{2}[/tex]
Step-by-step explanation:
"A number" is the part of the question you don't know, and therefore is the variable. Let's call it [tex]x[/tex] from now on.
So, when you add a number to 13 it means you are increasing 13 by that number, or [tex]13+x[/tex].
To divide it all by 2, simply put the above expression on a fraction with a denominator of 2:
[tex]\frac{13+x}{2}[/tex]
And there is your answer.
Using the graph, predict the y-value when the x-value is 13
A) 17
B) 18
C) 19
D) 20
9514 1404 393
Answer:
D) 20
Step-by-step explanation:
Each point marked on the graph is 3 units higher and 2 units to the right of the one before. The last dot is at x=9, so a dot at x=13 will be 2×2=4 units to the right. At the same rate of increase, it will be 2×3=6 units higher than 14.
The y-value is predicted to be 20 at x=13.
Which monomial represents the number of square units in the area of a circle with radius 3x 3 units?
Answer:
9[tex]\pi[/tex][tex]x^{4}[/tex]
Step-by-step explanation:
A monomial is an algebraic expression with one term.
So that,
area of a circle = [tex]\pi[/tex][tex]r^{2}[/tex]
if r = 3[tex]x^{2}[/tex], then;
area of the circle = [tex]\pi[/tex] x [tex](3x^{2} )^{2}[/tex]
= [tex]\pi[/tex] x 9[tex]x^{4}[/tex]
= 9[tex]\pi[/tex][tex]x^{4}[/tex]
The area of the circle is 9[tex]\pi[/tex][tex]x^{4}[/tex] square units.
Therefore, the monomial the represent the number of square units in the area of the circle is 9[tex]\pi[/tex][tex]x^{4}[/tex] square units.
The monomial which represents the number of square units in the area of a circle with radius 3x³ units is; 9πx⁶ square units.
The area of a circle is given in terms of its radius as follows;
Area = π r².However, the radius of the circle, r = 3x³ units.
Area, A = π (3x³)²Area, A = π 3² x⁶Area, A = 9πx⁶.Read more on Area of a circle;

Answer:
x -1
Step-by-step explanation:
The absolute value function is piecewise linear. When its argument is negative, it gives the opposite of that argument:
|x| = -x . . . for x < 0
|x| = x . . . for x ≥ 0
__
When the argument is some function of x, the same rules apply.
|x -1| = -(x -1) . . . for (x -1) < 0
|x -1| = x -1 . . . for x -1 > 0
The condition x-1 > 0 is equivalent to x > 1, so you have ...
|x -1| = x -1 . . . for x > 1
_____
The attached graph shows that |x-1| and x-1 are the same graph when x>1.

The table tells you ...
If the amount is over 31,850 but not over 77,100 the tax is 4386.25 +25% of (40,000 -31,850).
So, the tax is ...
$4,386.25 + 0.25(40,000 -31,850) = $4,386.25 + 0.25(8,150)
= $4,386.25 +2,037.50 = $6,423.75
