Answer:
x=3 and y= -1
Step-by-step explanation:
2x-7y=13
3x+y=8
Isolate y to get your third equation
y=8-3x
Sub third equation into first
2x-7(8-3x)=13
2x-56+21x= 13
23x= 13+56
x= 69/23
x=3
Sub x into third equation to get y value
y=8-3(3)
y= -1
help me please. mad confused lol
Answer:
P = 30 degrees, PQ = 6.93, PN = 8
Step-by-step explanation:
For the angle, just subtract the angles you already know from 180, so 180 - 90 - 60= P. P = 30 degrees.
For PQ, use tan60 = x/4, or 4tan(60), which equals 6.93.
For PN, use cos60 = 4/x, or 4/cos60, which equals 8.
Hopefully this helps- let me know if you have any questions!
which inequality has a solid boundary line when graphed?
Answer:
4th option
Step-by-step explanation:
An inequality using > or < has a broken boundary when graphed.
An inequality using ≥ or ≤ has a solid boundary when graphed
Then y ≥ 9x + 9 has a solid boundary
y = -4x + 3
8x + 2y = 8
Solve by using elimination.
Answer:
The equations are not compatible
Step-by-step explanation:
y = -4x + 3
8x + 2y = 8
substitute for y:
8x + 2(-4x + 3) = 8
simplify:
8x - 8x + 6 = 8
6 ≠ 8
This is very confusing

Why is a coordinate plane called a coordinate plane?
Answer:
The invention of the Cartesian Coordinate System is credited to René Descartes. He revolutionised mathematics by providing the first systematic link between Euclidean geometry and algebra. Thus, the Coordinate Plane is named after him. ("Cartesian" from his last name, Descartes.)
Step-by-step explanation:
A Cartesian plane (named after French mathematician Rene Descartes, who formalized its use in mathematics) is defined by two perpendicular number lines: the x-axis, which is horizontal, and the y-axis, which is vertical.
Round the following real number to the nearest hundredth: 67.498
Answer:
67.50
Step-by-step explanation:
Answer:
67.5The hundredth is always the second number after the decimal point (to the right).
So, when rounding to that number look at the number on the right of it, which in this case is 9.
Then, if the number is 5 to 9, round up, but if it is 0 to 4, round down.
In this case, the number above 0.49 is 0.5.

please help me i really need it geometry?
Answer:
height= 30 area= 2160
Step-by-step explanation:
I don't think this is even right, but since a triangle adds up to 180, subtract the 72 and both 39's from 180. that should give you 30, the missing number (the height)
Then, to find area the formula is a=b*h
You already have the base in the image and you already calculated the height
Again, I don't know if this is right. It's not the same as how I do it here
Answer:
h = 15, A = 540
Step-by-step explanation:
Since the 2 legs are congruent then h is a perpendicular bisector, dividing the triangle into 2 right triangles.
Using Pythagoras' identity on one of the right triangles
with leg 72 ÷ 2 = 36 and hypotenuse = 39
h² + 36² = 39²
h² + 1296 = 1521 ( subtract 1296 from both sides )
h² = 225 ( take square root of both sides )
h = [tex]\sqrt{225}[/tex] = 15
Then
A = [tex]\frac{1}{2}[/tex] × 72 × 15 = 36 × 15 = 540 mi²

C. 624 blocksStep-by-step explanation:
The volume of the box:
V = lwhSubstitute values:
V = 3 1/4 × 3 × 1 = 13/4 × 3 = 39/4The volume of each block:
V = 1/4×1/4×1/4 = 1/64Number of blocks that the box can fit:
39/4 ÷ 1/64 = 39/4 × 64 = 39 × 16 = 624Correct choice is C

Sonu had ₹25.50. He bought one pen for ₹17.75. How much money does he
have now?
PLS WRITE STEP BY STEP EXPLAINTION
Answer:
He has $7.75 left.
Step-by-step explanation:
To solve this problem you must subtract $25.50 by $17.75 because he bought the pen for 17.75 which is being taken away from his amount of money to start with ($25.50).
Step by step solving the subtraction problem:
$25.50-$17.50 = $7.75
So 25.50 - 17.75 you would need to make the 0 become a ten and then subtract 10 and 5, then you bring down the 5 from ($25.50) and make it 14 and subract 14 and 7. Then bring down the other 5 and make it 14 as well and subract 14 by 7 which is 7. Finally make the 2 a 1 and it will end up being 1-1 which is zero. So the answer will end up being $7.75. Hope that helps. Sorry that this answer took long for it to be posted.
