Answer:

x = —2

Step-by-step explanation:

h(x) = 4x — 1

if h(x) = -9 then 4x — 1 = -9

So:

[tex]4x - 1 = - 9 \\ 4x = - 9 + 1 \\ 4x = - 8 \\ x = - 2[/tex]

Answer:

x = -2

Step-by-step explanation:

[tex]-9=4x-1\\-8=4x\\-2=x[/tex]

Answer:

x = 3

perimeter: 18 units

Step-by-step explanation:

1. First, we should know that a regular polygon is a polygon that has all angles  the same angle measure and all sides the same side length.

2. (Solving)

Step 1: Simplify both sides of the equation.

Step 2: Subtract 7x from both sides.

Step 3: Subtract 10 from both sides.

Step 4: Divide both sides by -2.

Step 5: Check if solution is correct.

3. Now, since this polygon has 6 sides, it's a hexagon. To find the perimeter of a hexagon, we just multiply the length of one side 6 times.

Therefore, x = 3 and the perimeter is 18 units.

Answer:

Solution:-

Let the angle vertical to 64°be y.

y=64°(being vertically opposite angle)

Now,

X+y+62°=180°

X+64+62=180°

X=180°-126°

Therefore,x=54°

Answer:

yes

Step-by-step explanation:

[tex]\frac{16}{72}[/tex] ( divide numerator/ denominator by 8, the LCM of 16 and 72 )

= [tex]\frac{2}{9}[/tex]

[tex]\frac{18}{81}[/tex] (divide numerator/ denominator by 9 the LCM of 18 and 81 )

= [tex]\frac{2}{9}[/tex]

Both rational numbers simplify to [tex]\frac{2}{9}[/tex] and are equivalent

Distance = 5

Step-by-step explanation:

D= sqrt (x1-x2)^2 + (y1-y2)^2

(5-2)^2 + (8-4)^2=3^2 + 4 ^2 = 9 +16 = 25

Sqrt of 25 = 5

Distance = 5

Answer:

Step-by-step explanation:

Answer:

The trigonometric ratio that I would use to find the distance from the base of the tower to the keys is the tangent; tan (86°) = height / distance.

Step-by-step explanation:

You can draw a right triangle with angle 86°, opposite leg equal to the height (50 meter) and adjacent leg equal to the distance from the base of the tower to the keys: tan (86°) = 50 m / x

=> x = 50 m / tan(86°)

x = 50 m / 14.30 = 0.98 m

Let's solve your equation step-by-step.

x2+x=12

Step 1: Subtract 12 from both sides.

x2+x−12=12−12

x2+x−12=0

Step 2: Factor left side of equation.

(x−3)(x+4)=0

Step 3: Set factors equal to 0.

x−3=0 or x+4=0

x=3 or x=−4

Answer:

x=3 or x=−4

Answer:

m'=7

Step-by-step explanation:

they are parallel to each other so if slope of 1st line be "m" and 2nd line as "m' ", then we have:

m = m'

y-4=7x+14

y=7x+18

y=mx+h

So m = 7

& m' = 7

Answer:

[-5,6]

Step-by-step explanation:

The domain is the values that the input takes

x goes from -5 (inclusive) to 6 (inclusive)

-5 ≤x≤6

[-5,6]

Answer:

[-5, 6]

Step-by-step explanation:

    The domain of a function is the list of x values. Since the endpoints are shaded, that means those x values are included as well. Therefore, the domain of f is [-5, 6].
