Show the steps of solving. a) 6x - 2y = 28
4x + 2y = 12
PLEASE HELPPPPP I’ll give brainlist!!!
Answer:
x = 4 and y = -2
Step-by-step explanation:
Let 6x - 2y = 28 be equation (i)
and 4x + 2y = 12 be equation (ii)
To solve the following equations, first add the equations:
6x - 2y + 4x + 2y = 28 + 12
6x + 4x + 2y - 2y = 28 + 12
10 x = 40
x = 4
Substituting in (ii)
4x + 2y = 12
4*4 + 2y = 12
2y = 12 - 16
2y = -4
y = -2

Choose the correct solution for the inequality:
-4x + 5 >-5
A: x < 2.5
B: X > 2.5
C: X <-2.5
D: X > -2.5
Answer:
A
Step-by-step explanation:
We have -4x > -10, so 4x < 10
Answer:
A. x < 2.5
Step-by-step explanation:
you subtract 5 on both sides
then you get -4x > -10.
then you divide -4 on both sides
and you get x<2.5

-2x/3 + 11 = 14 please help me its not letting me put stuff I want
Answer:
x = -4 1/2
Step-by-step explanation:
-2x/3 + 11 = 14
subtract 11 from each side of the equation:
-2x/3 = 3
multiply both sides by 3:
-2x = 9
divide both sides by -2:
x = -4 1/2

Please help me answer the question below, I will give brainliest thing to whoever helps and gets it correct, thank you!
Answer:
y = 1/2 x + 5
Step-by-step explanation:
slope (m) = (y'-y) / (x'-x)
(y-6)/(x-2) = 1/2
y - 6 = 1/2 x - 1
y = 1/2 x + 5

Answer:
x = 13.6 in
Step-by-step explanation:
The arc x is calculated as
x = circumference of circle × fraction of circle
= 2πr × [tex]\frac{0.8}{2\pi }[/tex] ( cancel the 2π on numerator/ denominator )
= 17 × 0.8
= 13.6 in

Using the information that
5.2 x 67 = 348.4
write down the value of
c) 348.4 ÷ 52
Answer: 6.7
Step-by-step explanation:
We know that:
5.2*67 = 348.4
And we want to find the value of:
348.4/52 = x
So, let's return to the original equation.
5.2*67 = 348.4
Let's try to "construct" the quotient 348.4/52
The first step is to divide both sides by 5.2, then we get:
(5.2*67)/5.2 = 348.4/5.2
67 = 348.4/5.2
Now we have 5.2 in the denominator instead of 52, then we can divide both sides by 10 to get:
67/10 = ( 348.4/5.2)/10 = 348.4/(5.2*10) = 348.8/52
6.7 = 348.8/52
Then the solution to the quotient:
348.4/52 is 6.7
what’s the value of e?
Answer:
e = 129
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
e is an exterior angle of the triangle , then
e = 60 + 69 = 129

Step-by-step explanation:
1) [tex]y = x^2 + 4x + 3[/tex]
Lets split the middle term.
[tex]=> y = x^2 + 3x + x + 3[/tex]
[tex]=> y = x(x+3) + 1(x + 3)[/tex]
[tex]=> y = (x+1)(x+3)[/tex]
∴ [tex]x = -3 , -1[/tex]
2) [tex]y = 8x^2 - 22x + 5[/tex]
Lets split the middle term.
[tex]=> y = 8x^2 - 20x - 2x + 5[/tex]
[tex]=> y = 4x(2x - 5) - 1(2x - 5)[/tex]
[tex]=> y = (2x - 5)(4x - 1)[/tex]
∴ [tex]x =\frac{1}{4} , \frac{5}{2}[/tex]
3) [tex]y = x^2 - 5x[/tex]
[tex]=> y = x(x - 5)[/tex]
∴ [tex]x = 0 , 5[/tex]
4) [tex]y = 12x^2 + 18x[/tex]
[tex]=> y = 6x(2x + 3)[/tex]
∴ [tex]x = \frac{-3}{2} , 0[/tex]
5) [tex]y = x^2 - 7x + 12[/tex]
Lets split the middle term.
[tex]=> y = x^2 -3x - 4x + 12[/tex]
[tex]=> y = x(x - 3) - 4(x - 3)[/tex]
[tex]=> y = (x - 3)(x - 4)[/tex]
∴ [tex]x = 3,4[/tex]
6) [tex]y = 3x^2 + 10x + 8[/tex]
Lets split the middle term.
[tex]=> y = 3x^2 + 6x + 4x + 8[/tex]
[tex]=> y = 3x(x + 2) + 4(x + 2)[/tex]
[tex]=> y = (x + 2)(3x + 4)[/tex]
∴ [tex]x = -2 , \frac{-4}{3}[/tex]
7) [tex]y = x^2 - 4x - 45[/tex]
Lets split the middle term.
[tex]=> y = x^2 - 9x + 5x - 45[/tex]
[tex]=> y = x(x - 9) + 5(x - 9)[/tex]
[tex]=> y = (x - 9)(x + 5)[/tex]
∴ [tex]x = -5 , 9[/tex]
