Answer:
angle ABD =55 degree
angle BCD= 125 degree
Step-by-step explanation:
angle ABD and angle DBC are supplementary angles.
Hence, angle ABD +angle DBC = 180 --equation 1
angle ABD = (2x+15) ---equation 2
angle BCD = (4x+45) ------equation 3
ABD+DBC=180
(2x+15) + ( 4x+45 ) = 180
2x+4x+15+45=180
6x+60=180
6x=180-60
6x=120
x=120/6=20
angle ABD= 2x+15= 2(20) +15
=40+15= 55 degree
angle BCD= 4x+45 = 4(20) +45
= 80+45= 125 degree
Hence, angle ABD =55 degree
angle BCD= 125 degree

3. Thomas is ordering a soft pretzel at Papa's
Pretzel. Papa Pretzel charges $3 for the pretzel
and $0.50 for each topping, with a maximum of
4 toppings on a pretzel.
a. Find the domain.
b. Find the range.
Given that, Thomas is ordering a soft pretzel at Papa's Pretzel. Papa Pretzel charges $3 for the pretzel and $0.50 for each topping, with a maximum of 4 toppings on a pretzel.
Let, x denotes the number of toppings.
So, Cost, y = 3 + 0.5x, 0 ≤ x ≤ 4 as the maximum number of toppings is
So, the domain = [0, 4]
When x = 0,
y = 3 + 0 = 3
When x = 4,
y=3 + (0.5 * 4)
=3 + 2
=5
So, the range is [3, 5]

Then
m - 1 = - 5 - 1 = - 6
80% more then $20.00
Answer
$36

Hello there!
We are given the equation:
[tex] \displaystyle \large{ |4x - 1| = 1}[/tex]
Definition/Property
[tex] \displaystyle \large{ |a| = \sqrt{ {a}^{2} } } \\ \displaystyle \large{ |a| = b \longrightarrow a = \pm b} \\ \displaystyle \large{ |a| = \begin{cases} a \: \: (x \geqslant 0) \\ - a \: \: (a < 0) \end{cases}}[/tex]
First, cancel the absolute value sign and write plus-minus beside 1.
[tex] \displaystyle \large{ |4x - 1| = 1} \\ \displaystyle \large{ 4x - 1 = \pm 1} \\ [/tex]
Break in two cases.
[tex] \displaystyle \large{ 4x - 1 = \begin{cases} 1 \\ - 1 \end{cases}} \\ \displaystyle \large{ 4x = \begin{cases} 1 + 1 \\ - 1 + 1 \end{cases}} \\ \displaystyle \large{ 4x = \begin{cases} 2 \\ 0 \end{cases}} \\ \displaystyle \large{ x = \begin{cases} \frac{2}{4} \\ \frac{0}{4} \end{cases}}[/tex]
Therefore, x = 0 or 1/2

Answer:
he have to travel 12 cm/km
Step-by-step explanation:
lets find x by transposing
3x = 2x + 2 (as M is the midpoint)
3x - 2x = 2
x = 2
now put 2 instead of x
3x + 2x +2 = (distance from friends home to house)
3 (2) + 2 (2) +2
6 + 4 + 2
10 + 2
= 12

Los vértices de un triángulo en el plano cartesiano son A(-3, 4), B(4, 4) y C(4, -3). ¿Cuál es el área en unidades cuadradas del triángulo?
rapido pllsssss
El área del triángulo es de 24.5 unidades cuadradas.
En este problema, procedemos a resumir el procedimiento como sigue:
1) Calculamos las longitudes de los segmentos de línea AB, BC y AC por medio de la ecuación de longitud del segmento de línea.
2) Determinamos el semiperímetro del triángulo.
3) Determinamos el área del triángulo mediante la fórmula de Herón.
Si tenemos que [tex]A(x,y) = (-3, 4)[/tex], [tex]B(x,y) = (4, 4)[/tex] and [tex]C(x,y) = (4, - 3)[/tex], entonces aplicamos el procedimiento como sigue:
Paso 1 - Longitudes de segmentos línea
Segmento AB
[tex]l_{AB} = \sqrt{[4-(-3)]^{2}+(4-4)^{2}}[/tex]
[tex]l_{AB} = 7[/tex]
Segmento BC
[tex]l_{BC} = \sqrt{(4-4)^{2}+[(-3)-4]^{2}}[/tex]
[tex]l_{BC} = 7[/tex]
Segmento AC
[tex]l_{AC} = \sqrt{[4-(-3)]^{2}+(-3-4)^{2}}[/tex]
[tex]l_{AC} = 7\sqrt{2}[/tex]
Paso 2 - Cálculo del semiparámetro
[tex]s = \frac{l_{AB}+l_{BC}+l_{AC}}{2}[/tex]
[tex]s = \frac{14+7\sqrt{2}}{2}[/tex]
[tex]s = 7 + \frac{7\sqrt{2}}{2}[/tex]
Paso 3 - Cálculo del área del triángulo
[tex]A = \sqrt{s\cdot (s-l_{AB})\cdot (s-l_{BC})\cdot (s-l_{AC})}[/tex]
[tex]A = 24.5[/tex]
El área del triángulo es de 24.5 unidades cuadradas.

Answer:
7x = y - 7
Step-by-step explanation:
→ Replace the f(x) with a y
[tex]y=\frac{x-7}{x}[/tex]
→ Make x the subject by first multiplying both sides by x
[tex]xy=x-7[/tex]
→ Now rearrange to get all x on one side
[tex]x-xy = 7[/tex]
→ Factorise
[tex]x(1-y)=7[/tex]
→ Divide both sides by 1-y
[tex]\frac{7}{1-y}[/tex]
What is the domain and range?
Answer: The domain would be (0 hours, 2.5 hours) and the range would be (0 feet, 30,000 feet) in this graph.
Step-by-step explanation:
The domain refers to the set of possible input values. The domain of a graph consists of all the input values shown on the x-axis.
The range is the set of possible output values, which are shown on the y-axis.
An x-axis on a graph is the horizontal line and a y-axis on a graph is the vertical line. The x-axis in this graph would be the height in feet and the y-axis in this graph would be the time in hours.
