Answer:
(6,3)
Step-by-step explanation:
Here is the system of equations:
x+3y=15
4x+2y=30
Since we have x with a coefficient of 1 in the first equation, let's use substitution to solve this system.
In the first equation, subtract 3y from both sides
x=-3y+15
now substitute -3y+15 as x in the second equation, and solve for y
4(-3y+15)+2y=30
do distributive property
-12y+60+2y=30
combine like terms
-10y+60=30
subtract 60 from both sides
-10y=-30
divide by -10
y=3
Now, substitute y as 3 into either one of the equations to solve for x.
For example, let's use x=-3y+15
x=-3(3)+15
multiply
x=-9+15
x=6
The answer is x=6 and y=3. As a point it's (6,3)
Hope this helps!

Answer:
Any real number strictly larger than 9 and strictly less than 21.
Step-by-step explanation:
By triangle inequality, the sum of the lengths of any two sides are greater than the length of the third side.
We therefore could set up three inequalities.
x+6>15, x+15>6, 15+6>x
Solving these, we get x>9, x>-9, x<21 i.e. 9 < x < 21.
An airplane traveled 5000 miles in 10
hours. How many miles did it travel in
3 hours?
I
Step-by-step explanation:
Distance traveled in 10 hours = 5,000 miles
Distance travelled in 3 hours = 5,000 * (3/10)
= 1,500 miles.
Hence the airplane travelled 1,500 miles in 3 hours.
Step-by-step explanation:
Assuming it traveled at a constant speed, you can set up a proportion
[tex] \frac{5000}{10} = \frac{x}{3} [/tex]
X = (3*5000)/10
X = 1500 miles

Help plz i hate this but everytime I do this I get it worng
Answer:
The answer is 19.25
Step-by-step explanation:
Key skills needed: Fraction operations, decimal conversion
1) We are given the hint to use 9 as "b", and we get:
---> [tex]a = \frac{16}{8}(9) + \frac{10}{8}[/tex]
Let's do [tex]\frac{16}{8}(9)[/tex]
--> [tex]\frac{16}{8}[/tex] is the same as [tex]16[/tex] ÷ [tex]8[/tex]
16 divide by 8 is 2.
2) This means that it would be ---> [tex]2(9)[/tex] which is simply 2 times 9.
2 times 9 = 9 + 9 = 18
3) With that result, it would be ---> [tex]a = 18 + \frac{10}{8}[/tex]
Now, do [tex]\frac{10}{8}[/tex] (10 divided by 8) ---> Get 1.25
4) 18 + 1.25 = 19.25, so --> [tex]a = 19.25[/tex] is the answer

If Cathy receives all the discounts (30%, 20%, 10%, 15%, and an additional 20% Holiday Bonus Bucks discount, how much will she pay for the $90 sweater?
Answer:
She will pay $30.8448.
Step-by-step explanation:
Consider the provided information.
The price of the sweater is $90.
She gets a discount of 30% it means she needs to pay only (100-30)%=70% of $90.
70% of $90 = [tex]0.7\times 90 = 63[/tex]
Now she gets a discount of 20% it means she needs to only 80% of $63.
[tex]0.8\times 63=50.4[/tex]
If she gets a discount of 10% on $50.4 it means she needs to pay 90% of 50.4
[tex]0.9\times 50.4=45.36[/tex]
If she gets a discount of 15% on 45.36 it means she needs to pay only 85% of 45.36
[tex]0.85\times 45.36 =38.556[/tex]
Now she gets an additional 20% holiday Bones Buck discount it means she needs to pay 80% of 38.556
[tex]0.8\times 38.556=30.8448[/tex]
Hence, she will pay $30.8448.

The volume of the box as a polynomial is x³-48x²+560.
What is volume?Volume is defined as the space occupied within the boundaries of an object in three-dimensional space.
Given that, a box is created from a rectangular piece of cardboard 20 centimetres by 28 centimetres by cutting a square from each corner and folding up the sides,
Volume of a cuboid = L*B*H
Volume = x(x-20)(x-28)
= x(x²-28x-20x+560)
= x(x²-48x+560)
= x³-48x²+560x
Hence, The volume of the box as a polynomial is x³-48x²+560.

Enter the equation of the line in slope-intercept form. Slope is 1/5 and (5,6) is on the line.
Answer:
y = 1/5x + 5
Step-by-step explanation:
If you plot (5,6) on a graph, and count down 1 point, and over to the left 5 points, you will get to the y-axis. Then, the point that is on the y-axis is the y-intercept. That is 5. The 5 goes at the end of the equation.
What is the y intercept of the following equation -5y-3x=10
It has to look something like this
Answer:
-2
Step-by-step explanation:
First, let's put this in slope-intercept form:
-5y-3x=10
5y = -3x - 10
y = (-3/5)x - 2
The y-intercept is -2.

Find the square roots of 16
[tex]\longmapsto \sqrt{{16} } \\ \\ \longmapsto{4} [/tex]
i don’t understand this at all
Answer:
x=8
Step-by-step explanation:
You would set them equal to each other to get 9x-13=6x+11.
You would them move 6x over so -6x on both sides. This would then get you 3x-13=11.
Then move the -13 over so add 13 to both sides to get 3x=24
Then get x by itself so divide by 3 to get x=24/3.
Then that simplified is 8

Step-by-step explanation:
If there's a repitition in the X values of the pair (x,y), it is not a function.
Write down the integer values of x that satisfy the inequality -2 < x _<4
Those integers are {-1,0,1,2,3,4} (integers in the range -2 and 4)
The integer values of x that satisfy the given inequality are {-2, -1, 0, 1, 2, 3, 4}.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given inequality is -2<x≤4.
The integer values of x that satisfy the inequality are
{-2, -1, 0, 1, 2, 3, 4}
Therefore, the integer values of x that satisfy the given inequality are {-2, -1, 0, 1, 2, 3, 4}.
