Answer:
x = -1/2y+2
Step-by-step explanation:
4x+2y=8
Step 1: Add -2y to both sides.
4x+2y+−2y=8+−2y
4x=−2y+8
Step 2: Divide both sides by 4.
4x/4 = -2y+8/4
x = -1/2y+2

Which of the following point-slope form equations could be produced with the points (4, 5) and (-3, -5)?
Given:
The two points are (4,5) and (-3,-5).
To find:
The point-slope form equations could be produced with the given points.
Solution:
Slope formula:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The two points are (4,5) and (-3,-5). So, the slope of the line is:
[tex]m=\dfrac{-5-5}{-3-4}[/tex]
[tex]m=\dfrac{-10}{-7}[/tex]
[tex]m=\dfrac{10}{7}[/tex]
The point slope form of a line is:
[tex]y-y_1=m(x-x_1)[/tex]
Where, m is the slope of the line.
The slope of the line is [tex]m=\dfrac{10}{7}[/tex] is passes through the point (4,5). So, the point slope form is:
[tex]y-5=\dfrac{10}{7}(x-4)[/tex]
The slope of the line is [tex]m=\dfrac{10}{7}[/tex] is passes through the point (-3,-5). So, the point slope form is:
[tex]y-(-5)=\dfrac{10}{7}(x-(-3))[/tex]
[tex]y+5=\dfrac{10}{7}(x+3)[/tex]
Therefore, the point slope form of the given line is either [tex]y-5=\dfrac{10}{7}(x-4)[/tex] or [tex]y+5=\dfrac{10}{7}(x+3)[/tex].

Use the diagram to find the following bearings.
9514 1404 393
Answer:
(a) 15°
(b) 256°
(c) 133°
(d) 313°
Step-by-step explanation:
We assume your bearings are to be reported as an angle measured clockwise from north.
A) The given angle is the bearing: 15°.
__
B) The bearing can be found by subtracting this angle from 450°:
450° -194° = 256°
__
C) The bearing can be found by adding 90° to the angle shown:
43° +90° = 133°
__
D) The reverse bearing can be found by adding 180°:
133° +180° = 313°
_____
Additional comment
Angles in Cartesian coordinates are conventionally measured counterclockwise from the +x axis. In that sense, the angle of C could be considered to be -43°.
Bearing angles are reported different ways. One of them is as an angle in the range 0–360°, measured clockwise from north (up, or +y axis). As such, it can be found by subtracting the conventional Cartesian angle from 90°.
When the Cartesian angle is more than 90°, 360° must be added to the difference to bring it back into the desired 0–360° range. Essentially, angles greater than 90° must be subtracted from 90° +360° = 450°.
Reverse bearings are found by adding or subtracting 180°.
__
An alternate convention for reporting bearings is as an angle in the range 0–90° east or west from north or south. In this convention, A = N15E, B=S76W, and C=S47E.
Occasionally, you will see the angles B and C reported from east or west: B=W14S; C=E43S. This keeps the angles in the 0–45° range. This is NOT a recommended way to report bearings.
Reverse bearings are found by swapping N/S and E/W. That is, the bearing from A to O is S15W, for example.

Jill is flying a kite that has a 30ft. long string. If Jill is 5.4 ft. tall and her arm is making a 31-degree angle with the ground, how high is the kite in the air?
Answer:
20.85ft
Step-by-step explanation:
height of kite = person's height + vertical component of kite at the angle
= 5.4ft + 30sin31

en un velocímetro se registra una velocidad de 8.5 m/seg ¿cual sería la velocidad en km/hr?
Answer:
x = 30.6 km/hr
Step-by-step explanation:
Dados los siguientes datos;
Velocidad = 8.5 m/s
Para convertirlo a km /hr;
1 m/s = 3.6 km/hora
8.5 m/s = x km/hora
Multiplicación cruzada, tenemos;
x = 8.5 * 3.6
x = 30.6 km/hora
Velocidad se puede definir como la tasa de cambio en el desplazamiento (distancia) con el tiempo. La velocidad es una cantidad vectorial y, como tal, tiene magnitud y dirección. Matemáticamente, la velocidad viene dada por la ecuación;
[tex] Velocidad = \frac {distancia} {tiempo} [/tex]

Find the probability of spinning red on every spin
Find the area of the polygon.
Answer:
A = 372 units²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 24 , b₁ = 24, b₂ = 7 , then
A = [tex]\frac{1}{2}[/tex] × 24 × (24 + 7) = 12 × 31 = 372 units²
What would 'x' be in the equation -3(x-2)=6?
Answer:
[tex]\boxed {\boxed {\sf x=0}}[/tex]
Step-by-step explanation:
To solve this equation, we must isolate the variable (x) using inverse operations.
[tex]-3(x-2)=6[/tex]
x-2 is being multiplied by -3. The inverse operation of multiplication is division, so we divide both sides by -3.
[tex]-3(x-2)/-3= 6/-3\\(x-2)=6 /-3 \\(x-2)= -2[/tex]
2 is being subtracted from x. The inverse operation of subtraction is addition, so add 2 to both sides of the equation.
[tex]x-2+2=-2+2\\x=-2+2\\x=0[/tex]
In this equation, x is equal to 0.
Solve the simultaneous equations
x - 3y = -23
5x + 2y = 4
Answer:
(-2,7)
x= -2
y= 7
Step-by-step explanation:
We have
x-3y= -23
5x+2y=4
Let's solve this through substitution
let's start by adding 3y in the first equation
x= -23 +3y
plug this into the second one
5(-23+3y)+2y=4
-115+15y+2y=4
17y=119
y=7
Plug this y value into our first equation
x-3(7)= -23
x-21= -23
x= -2

At a Noodles & Company restaurant, the probability that a customer will order a nonalcoholic beverage is .51. Find the probability that in a sample of 10 customers, fewer than 8 will order a nonalcoholic beverage.
Answer:
1-0.7584=0.2416
Step-by-step explanation:
The probability nobody will order a non-A beverage is .56^8=0.0097
all 8 will order a non-A beverage is 0.44^8=0.0014
fewer than 6:
look at 6,7,8
Those add to 0.0794 and the answer is 1- that or 0.9206. Also 2nd VARS (.44,8,5)

You have 2 shapes, a rectangle and a half circle.
Area of rectangle = 3 x 8 = 24
Area of a half circle = 1/2 x pi x r^2
Area of half circle = 1/2 x 3.14 x 4^2
Area of half circle = 25.12
Total area = 24 + 25.12 = 49.12 square units

A f and g share the same root(s)
B f and g share one root in common but each have another root that is not shared
C f and g share no roots in common
9514 1404 393
Answer:
C f and g share no roots
Step-by-step explanation:
The roots of a polynomial function are the values of x that make factors of the function be zero.
f(x) = x(x +4). The roots of f are -4 and 0.
g(x) = (1/2)(x+3)(x-4). The roots of g are -3 and 4.
f and g share no roots in common.

find the volume of the following square pyramid. geometry hw
Given:
The square base pyramid with height 3 cm and base edge 2 cm.
To find:
The volume of the square pyramid.
Solution:
Volume of a square base pyramid is:
[tex]V=\dfrac{1}{3}Bh[/tex] ...(i)
Where, B is the base area and h is the height of the pyramid.
Base is a square with edge 2 cm, so the base area is:
[tex]B=a\times a[/tex]
Where, a is the edge of the square base.
[tex]B=2\times 2[/tex]
[tex]B=4[/tex]
Putting [tex]B=4,h=3[/tex] in (i), we get
[tex]V=\dfrac{1}{3}(4)(3)[/tex]
[tex]V=4[/tex]
Therefore, the volume of the given pyramid is 4 cm³.
