Substitute x = 2y - 2 into the expression 5x
(1 Point)
Answer:
Substituting x= 2y-2 in 5x
5(2y-2)
10y-10
10(y-1)
all you have to do is replace the x with 2y-2
x=2y-2
5(2y-2)
10y-10
you can further factorise
10(y-1)
What’s the solution for k/2=4
Answer: k=8
Step-by-step explanation:
k/2 = 4
k = 4 x 2
k = 8
Check: 8/2=4
Answer:
[tex]k=8[/tex]
Step-by-step explanation:
[tex]\frac{k}{2} = 4[/tex]
Multiply both sides by 2 to isolate k
[tex]\frac{k}{2}(2) = 4(2)\\k=8[/tex]

Find the value of m so that the line y = mx - 5 will pass through the point (-2,3).
Answer:
Step-by-step explanation:
b/c there is a -5 we know that the line will pass through point (0,-5) and we also want the line to pass through (-2,3) so use those two points to find the slope
m = 3-(-5) / -2 -0
m = 3+5 / -2
m = -8/2
m = -4
Present the trigonometric relations of the ratios via,
Pythagoras Theorem
Answer:
ypotenuse squared = adjacent squared + opposite squared
Step-by-step explanation:
sin θ =opposite/hypotenuse
tan θ = opp/adjacent
cos θ = adj/hyp
Pythagoras Theorem states that hypotenuse squared = adjacent squared + opposite squared

Stan worked 4 years less than Marco. This year Stan has worked 29 years. If b is how long Marco worked, the equation b – 4 = 29 represents this situation. How can you get the variable alone on one side of the equation?
Answer:
Add to Both sides
Step-by-step explanation:
Is this table a function?
Yes, because every y is matched with only one x
Yes, because every x is matched with only one y.
No, because the table does not include the point (0, 0)
No, because the table is not proportional.

Answer:
a. 16
Step-by-step explanation:
Consider these 3 values.
[tex] \sqrt{16} \\ \sqrt{27} \\ \sqrt{35} [/tex]
Factor 16,27 and 35.
[tex] \sqrt{4 \times 4} \\ \sqrt{3 \times 3 \times 3} \\ \sqrt{3 \times 3 \times 5} [/tex]
Pull out two same numbers out of the root.
[tex]4 \\ 3 \sqrt{3} \\ 3 \sqrt{5} [/tex]
Rational only when there are no square roots after simplify/evaluating.
Thus a. 16 is only rational here.

Identify the x- and y-intercepts of the equation
4x - y = 8
[tex]\boxed{\boxed{\pink{\sf \leadsto The \ x - intercept \ is \ (2,0) \ \& \ the \ y \ intercept \ is \ (-8,0) }}}[/tex]
Step-by-step explanation:A linear equation is given to us and we are required to find x and y Intercepts to it. So the given linear equation to us is ,
[tex]\bf \implies 4x - y = 8 \\\\\bf\implies \dfrac{1}{8} \bigg( 4x -y\bigg) =\frac{1}{8}\times 8 \\\\\bf\implies \dfrac{4x}{8}-\dfrac{y}{8} = \dfrac{8}{8} \\\\\bf\implies \dfrac{x}{2}-\dfrac{y}{8}=1 \\\\\bf\implies\boxed{\red{\bf \dfrac{x}{2}+\dfrac{y}{-8}=1 }}[/tex]
Hence on comparing to standard form we get
x intercept as (2 , 0 )y intercept as (0,-8) Hence the x - intercept is ( 2 , 0 ) and the y - intercept is ( 0 , -8 ) .Answer:
x = (2,0)
y = (0,-8)
Step-by-step explanation:
Remember than an intercept always has the other number as 0.
Let's put this in standard form of a linear equation, or y = mx + b
4x - y = 8
-y = -4x + 8
y = 4x - 8
"b" is the y intercept. The y intercept is -8, or (0,-8)
Now, to find the x intercept, all we have to do is substitute 0 for y.
0 = 4x -8
8 = 4x
2 = x
The x intercept is 2, or (2,0)
Find a.
Round to the nearest tenth:
2 cm
с
150
1050
a =
= [? ]cm
Answer:
a = 1.8 cm
Step-by-step explanation:
Here. we want to find the value of a
To do this, we are going to use the sine rule
it states that the ratio of a side and the sine of the angle that faces the side is a constant for all the sides of a triangle
From the diagram, we have that;
The angle facing a is;
180-15-105 = 60
So, we have that
a/sin 60 = 2/sin 105
a = 2sin 60/sin 105
a = 1.794 cm
For the equation y=12x-4
Answer:
12 is the slope and -4 is the y-intercept
Answer:
12 is the slope and -4 is the y-intercept
Step-by-step explanation:
What are the solution(s) of x squared minus 4 = 0
Answer:
x=2 or x= -2
Step-by-step explanation:
x^2 - 4 = 0
x ^2 − 4 + 4 = 0 + 4
x^2 = 4
√ ( x ^2 ) = √ 4
= ± 2 = { x 1 = − 2
x 2 = 2
Answer:
X=2 or X=-2
Step-by-step explanation:
x^2 - 4 = 0
x ^2 − 4 + 4 = 0 + 4
x^2 = 4
√ ( x ^2 ) = √ 4
= ± 2 = { x 1 = − 2
x 2 = 2
