Answer:
5/8 =x
Step-by-step explanation:
9=8/5(x+5)
Multiply each side by 5/8
5/8 *9= 5/8 *8/5(x+5)
45/8 = x+5
Subtract 5 from each side
45/8 - 5 = x+5-5
45/8 -5 = x
Get a common denominator
45/8 - 5*8/8 =x
45/8 - 40/8 =x
5/8 =x
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

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

3x -(-2-4x)=
What does this equals??
Answer:
7x + 2
Step-by-step explanation:
Original Equation: 3x − ( −2 − 4x)
First, we distribute the negative sign:
= 3x + (−1) (−2−4x)
=3x + (−1)(−2) + (−1)(−4x)
= 3x + 2 + 4x
Using the communitive property of addition, we can write:
= 3x + 4x + 2 (Instead of 3x + 2 + 4x)
Combining like terms, we get:
= (3x + 4x) + 2
= 7x + 2
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)

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

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)
