Answer: Two lines that intersect at about three halves comma negative 3. One line has a positive slope and the other has a negative slope.
Step-by-step explanation:
Given equations of line:
y = 2x – 6 ...(i)
y = –4x + 3 ...(ii)
On comparing with y=mx+c (slope-intercept form), where m= slope ,= y-intercept.
(i) has positive slope (2) and (ii) has negative slope(-4).
Eliminate (ii) from (i), we get
0 = 6x-9
⇒ 6x=9
⇒ [tex]x=\dfrac32[/tex]
Put value of x in (i), we get
[tex]y=2(\dfrac32)-6\\\\\Rightarrow\ y=3-6=-3[/tex]
Point of intersection = (three halves, negative 3)
Answer:
d
Step-by-step explanation:
Two lines that intersect at the origin. One line has a positive slope and the other has a negative slope
Solve the system by substitution.
3x-6y=2
4x+3y=-1
Answer:
y = -1/3
x = 0
Step-by-step explanation:
3x-6y = 2 then 3x = 2+6y, x=(2+6y)/3
4x+3y = -1
substitute for x
4(2/3+2y)-6y = 2
8/3+8y-6y = 2
reduce
2y = 2-8/3
2y = -2/3
divide both sides by 2
y = -1/3
4x+3(-1/3) = -1
4x = 0
x = 0
simplify a-c when a=5,c=-1
Help me to find the value of x, please
Answer:
x = 4
Step-by-step explanation:
The easiest way to do this is to look at the vertical angles. (15x)º has its own vertical angle, and the part with (8x-2)º and 90º does as well.
Also, every angle will add up to 360º, which is a crucial part of the equation
Do 15x + 15x + 90 + 90 + 8x - 2 + 8x - 2 = 360
This can be simplified into this once you combine like terms:
46x + 176 = 360
Subtract 176 from 360, which will give you:
46x = 184
Divide by 46 on both sides, resulting in:
x = 4
To check the answer, plug in 4 for x:
15(4) + 15(4) + 90 + 90 + 8(4) - 2 + 8(4) - 2 = 360
60 + 60 + 90 + 90 + 32 - 2 + 32 - 2 = 360
120 + 180 + 60 = 360
360 = 360, x is 4
Hope this made sense!

decrease £270 by 13%. *
Sorry for posting again
Answer:
£234.90
Step-by-step explanation:
270(1-13/100)
lets break it down:
step 1= 13/100=0.13
step 2= 1-0.13=0.87
step 3= 270 x 0.87=234.9

2/5 of a number is -8 what is the number
Answer:
-20
Step-by-step explanation:
let x be the whole. 2/5 of x = -8 so -8 1/5 is -4. -4*5 to find the whole so its -20
Answer: The number is 35
If 2/5 of a number is 14, then we will perform a function of cross multiplication in order to determine the missing number.
Step-by-step explanation:
Let the missing number = y
To perform a cross multiplication, firstly, we multiply the numerator of first fraction by the denominator of the second fraction.
Secondly, we multiply the denominator of the first fraction by the numerator of the second fraction. Then, the resulting values are divided by each other to get a final numerical value.
Therefore, the missing number (y) will the denominator of the second fraction i.e. 14/y . The first fraction is 2/5.
Thus,
2/5 of 14/y
2/5= 14/y
(2 x y) = (5 x 14)
(2y) = (70)
2y = 70
Since we are looking for value of y, divide both sides by the value beside y
Thus,
2y/2 = 70/2
y = 35
Therefore, the missing number is 35
