which is parallel to the line y = -5/8x+6
Answer:
The answer lies in the gradient.
Step-by-step explanation:
The gradient in this equation is -5/8. If any line has the same gradient as the equation above they are parallel because they have the same slant or tilt. Gradient determines if a line is parallel between linear line graphs. If the gradient between two linear line graphs are equal that means that they are parallel.
First identify what is the gradient of a line. The gradient is usually the number that is multiplied with x. In this case (-5/8x), -5/8 is the gradient.

7. Find the perimeter of the figure.
x+12
x + 2
Answer:
The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.
Please help me with number 4.
Can someone help me.....
Answer:
The square root of 2 is between 1 and 2, so radical 2 is about 1.4.
Step-by-step explanation:
You can plot a 1 on the very left and a 2 on the very right of the number line.
Since there is no formal square root of 2, you have to estimate.
It has to be less than 2 because if you multiply 2 * 2 you get 4 and that's too big; we want to get 2.
It also has to be greater than 1 because 1 * 1 = 1 and that's too low.
I would estimate it to be right before the middle line.

One angle of a right triangle is 2 less than 3 times the size of the other acute angle. What is the measure of each
angle?
Explanation:
Right-angled triangles have one of their angles to be 90°.
Angles in a triangle is 180°
=>The other two angles will sum up to 90°
Let x represent the other acute angle
2 less than 3 times the size of the other acute angle.
3(x)-2=one angle.
Equating both angles to 90°
=> other acute angle + one angle =90°
=> x+3x-2=90°
=>4x-2=90°
=>4x=90-2
=>4x=88
Divide both sides by 4
x=22°
Other acute angle=22°
One angle= 3(22)-2
=>66-2
=>64°
Proof= 22+64+2+90=180°

Answer:
Number two: x > -9/2, x < 3/2
Number one: x is less than or equal to 3/4, x is greater than or equal to - 13/4
Step-by-step explanation:
Number one:
|4x+5| > 10-2
|4x+5| > 8
4x+5 > 8
-(4x+5) > 8
x > 3/4
x < -13/4
x > 3/4, x < -13/4
(all of these signs are greater than or equal to and less than or equal to)
Number two:
|2x+3| > -6
2x+3 > -6
-(2x+3) > -6
x > -9/2
x < 3/2
x> -9/2, x < 3/2
(all of these signs are correct and not greater than or equal to or less than or equal to)

From 1985 through 1995, the yearly gross farrm revenue (in millions) in the United States can be modeled by the function R(t)=-t^2+7t+159 and the yearly farm cost (in millions) in the United States can be modeled by the function c(t)=t^2+131 where t is the number of years since 1985. Write a new function, P(t), that models the yearly profit after 1985
The profit function is simply the difference between the revenue function and the cost function. The profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]
Given that:
[tex]R(t) = t^2 + 7t + 159[/tex]
[tex]c(t) = t^2 + 131[/tex]
The profit function P(t) is calculated as follows:
[tex]P(t) = R(t) - c(t)[/tex]
So, we have:
[tex]P(t) = t^2 + 7t + 159 - (t^2 + 131)[/tex]
Open brackets
[tex]P(t) = t^2 + 7t + 159 - t^2 - 131[/tex]
Collect like terms
[tex]P(t) = t^2- t^2 + 7t + 159 - 131[/tex]
[tex]P(t) = 7t + 28[/tex]
Hence, the profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]

S(-4, -6) and T(-7, -3); Find R.
Answer:
(13,-6)
Step-by-step explanation:
The midpoint is the exact halfway point, so all you need to do is find the distance between those two points and apply it again.
First find the x coordinate. The distance from -9 to 2 is 11. So you add 11 to 2, and you get 13, which is your x coordinate.
Then do the same thing with the y coordinate. And you get -6.
Your endpoint is (13,-6)
solve the formula for y (pls give steps)
-10x +2y = 4

The perimeter of a rectangular garden is 24. If the length is half the width, what is
the width?
Let length be x
Width be 2xATQ
[tex]\\ \sf\longmapsto 2(L+B)=24[/tex]
[tex]\\ \sf\longmapsto 2(x+2x)=2=[/tex]
[tex]\\ \sf\longmapsto 2(3x)=24[/tex]
[tex]\\ \sf\longmapsto 6x=24[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{24}{6}[/tex]
[tex]\\ \sf\longmapsto x=4[/tex]
Step-by-step explanation:
let the length be X and breadth be 2x
p=2(l+b)
24=2(X+2x)
24=2x+4x
24=6x
24÷6=x
4=X
so,we know that
X=4 and 2x=2 X 4= 8
therefore the value of breadth or width is 8
