Write an equation to match each graph
Answer:
y=lxl
Step-by-step explanation:
Answer:
y=|x|
Step-by-step explanation:
The first graph is V shaped graph centered at origin, (0,0) and the graph is not shifted or translated. So, the equation of first graph is,
Find the area of the shaded region.
solve the simultaneous equation
2x + 4y=1
3x - 5y=7
Answer:
x = 3/2 or 1.5.
y = -1/2 or -0.5.
Step-by-step explanation:
Solve for one equation, one variable.
2x + 4y = 1
subtrract 4y from both sides.
2x = 1 - 4y
divide by 2 to get x by itself.
x = 1/2 - 2y
Now that we have this, we can put it into the other equation.
3x - 5y = 7
Substitute variable.
3(1/2 - 2y) - 5y = 7
Distribute the 3.
1.5 - 6y - 5y = 7
Combine terms.
-11y + 1.5 = 7
Subtract by 1.5.
-11y = 5.5
Divide by -11.
y = -1/2, or -0.5.
Now we can find x. Substitute this into the initial equation.
2x + 4y = 1
Substitute variable.
2x + 4(-1/2) = 1
Multiply.
2x + (-2) = 1
Simplify.
2x - 2 = 1
Add 2 to both sides.
2x = 3
Divide by 2.
x = 3/2, or 1.5.
x = 3/2 or 1.5.
y = -1/2 or -0.5.

Answer:
34.8 to 1 dp
Step-by-step explanation:
18/2 = 9
Area of rectangle 18 X 9 = 162 cm^2
diameter of each circle 9
radius = 4.5
Area of a circle = πr^2
π X 4.5^2 = 63.6172512
63.6172512 X 2 (there are 2 circles) = 127.234502
162 - 127.234502 = 34.7654975
34.8 to 1dp

inside of a triangle is 180 degrees
[tex]180=90+5x+2+4x-11\\180=5x+4x+90+2-11\\180=9x+81\\180-81=9x+81-81\\99=9x\\99/9=9x/9\\11=x[/tex]
now that we have our x we can find the angles

How much larger is 6 x 105 compared to
2 x 103? Explain how you know.
Answer:
397
Step-by-step explanation:
well we know that 6*105= 630 and 2*103 = 206 so we subtract 206 from 630 giving us 397
hope this helps.
Answer:
6×105=630
Step-by-step explanation:
2×103=206 so 6×105 is greater with 424 yimes2×103.

9514 1404 393
Answer:
5.3
Step-by-step explanation:
The Pythagorean theorem applies. The square of the hypotenuse is equal to the sum of the squares of the other two sides.
8² = x² + 6²
64 = x² +36
28 = x²
√28 = x ≈ 5.3
The missing measure is 5.3.

Eliminate the y in the following system of equations. What is the result when you add the two equations?
3x - 2y = 8
x + y = 6
Answer:
X=4
Step-by-step explanation:
3x-2y=8
x+y=6
multiply second equation by 2 so you can eliminate y
2(x+y)=2(6)
2x+2y=12
now add two equations together
first equation: 3x-2y=8
modified second equation 2x+2y=12
added together eliminates y. 5x+0=20
X=4
