At what point do the lines y = x - 8 and y = - 3x + 16 intersects?
Equating both expressions;
x - 8 = -3x+16
Collect like terms
x+3x = 16+8
4x = 24
x = 24/4
x = 6
Substitute x = 6 into any of the equation
Recall that y = x - 8
y = 6 - 8
y = -2
Hence the point (x, y) where they intersects is at (6, -2)

Which ratio is not equivalent to the other three? A 2 3 B 12 15 C 18 27 D 6 9
Answer: B= 12 15
Step-by-step explanation:
The given ratios are
A) 2 3= 2: 3 already in its simplest form
B) 12 15 =12:15 Changing to its simplest form, we divide both by 3 giving us 4:5
C) 18 27 =18: 27 Changing to its simplest form, we divide both numbers by 9 giving us =2:3
D)6 9=6:9 Changing to its simplest form, we divide both by 3 giving us
2:3
Therefore the ratio not equivalent to other three is 12:15

A cube that has a length of 1cm on each side has a volume of 1 cmHow many cubic
centimeters are in 1 cubic meter? (Hint: The answer is not 100.)
Answer:
1 cubic centimetre =1 × 10^-6 cubic metre
Step-by-step explanation:
A cube that has a length of 1cm on each side has a volume of 1 cm. How many cubic centimeters are in 1 cubic meter? (Hint: The answer is not 100.)
From the above question,
Side length of the cube = 1cm
Volume of the cube = (side length)³
= (1cm)³
= 1 cm³
How many cubic centimeters are in 1 cubic meter?
Note that:
100 cm = 1 m
1 cm³ = x m³
1 cm³ = (1/100 × 100 × 100)m³
1 cm³ = 1 × 10^-6 m³
Therefore,
1 cubic centimetre =1 × 10^-6 cubic metre

Answer:
x is 13
y is 39
Step-by-step explanation:
Answer:
y= 39 x= 10
Step-by-step explanation:
congruent isosceles triangles
longer sides measure the same 13 and 13 39 and 39 ( y =39)
39/30 = 13/x
cross multiplication:
39x = 13x30
39x = 390
x=10

The terminal ray of angle β, drawn in standard position, passes through the point (−7, 2√3).
What is the value of cosβ?
Answer: -7√61/61
Step-by-step explanation:
I got the answer wrong on my test and this was the correct answer shown.
The cosine of the terminal ray of angle β comes to be -7/√61.
What is the cosine of an angle?The cosine of an angle is the ratio of the adjacent side to the hypotenuse.
By Pythagoras' theorem
Hypotenuse² = 7²+(2√3)²
Hypotenuse =√61
From the diagram attached
[tex]Cos(180-\beta )=\frac{7}{\sqrt{61} }[/tex]
We know [tex]Cos(180-\beta )=-Cos\beta[/tex]
[tex]-Cos\beta =\frac{7}{\sqrt{61} }[/tex]
[tex]Cos\beta =\frac{-7}{\sqrt{61} }[/tex]
So, the value of cosβ =-7/√61.
Hence, The cosine of the terminal ray of angle β comes to be -7/√61.
