What is the slope of the function y = -3/4x + 5
Answer:
The slope is -3/4
Step-by-step explanation:
The equation is written in this form: y = mx + b
Where, m is the slope and b is the y-intercept
hello, could someone help me with this question, thank you.
It's C.
Basically, when youre dividing something, the bases would stay the same but the exponents would change. For division, you'd have to substract the exponent of the denominator from the denominator (of like bases, of course)
In this case, it's 10^8-(-3).
The only reason it's not 10⁵ is because of the negative 3. If it were a positive 3, it would become 10⁵.
solve for the inequality
-2+2x>-16
can someone help please? HURRYY!!
Answer:
103 ft^2
Step-by-step explanation:
Long sides: 2(8*4) = 64 ft^2
Under side: 3*8 = 24 ft^2
Triangles: (2(3*5))/2 = 15 ft^2
64+24+15 = 103
Answer:
103
Step-by-step explanation:
the base = 3x8 = 24
the sides are= 4 x 8 = 32
two sides = 64
triangle = 5x 3 x1/2 = 7.5
7.5 x 2 = 15
total = 103

if y varies directly as the square root of x and y=3, x=3. calculate y when x=64
Answer:
y = 64√3
Step-by-step explanation:
Step(i):-
Given that the 'y' varies directly as √x
⇒ y∝ √x
⇒ y = k√x
Put y=3 and x=3
3 = k ×√3
√3 k = √3×√3
After cancellation '√3' on both sides, we get
k = √3
Step(ii):-
Given that x=64 and k = √3
We have a function y = k√x ..(i)
substitute x =64 and k = √3 in equation (i)
y = √3 × 64
y = 64√3
Solve for x.

Add. Select the sum in simplest form.
2/3 + 1/5
Answer:
0.867 in decimal form
13/15 in fraction form
Step-by-step explanation:
1. Add
2/3 + 1/5 = 10/15 + 3/15
2. Simplify the sum, 13/15
1 is the greatest common divisor of 13 and 15. The result can't be further reduced.
3. Convert 13/15 into a decimal.
What is the measure of all exterior angles of a pentagon
Answer:
72 degrees for each exterior angle and 360 degrees for all of them summed.
Step-by-step explanation:
An exterior angle of a polygon is the angle between the line extending one of its sides and the next side. As you go around a regular n sided polygon doing this, you will rotate through a complete circle of 360 degrees. All these angles are equal, so each one is 360/n.
For the pentagon, n=5, so the sum of all its exterior angles is 360 degrees and each exterior angle is 360/5=72 degrees.

Cual es el valor de un esfero cuando la docena se compra en $7848? Area de un triangulo de 9 unidades de base y 6 unidades de altura? Cien veces la suma de 4.5 con 2.71 Porfavooor es para una tarea de mañana D:
Answer:
a) $654
b) 27 unidades cuadradas
c) 721
Step-by-step explanation:
a) ¿Cuál es el valor de un bolígrafo cuando la docena se compra por $ 7848?
Una docena = 12
Por eso:
12 bolígrafos = $ 7848
1 bolígrafo = $ x
Cruz multiplicar
12 bolígrafos × $ x = 1 bolígrafo × $ 7848
$ x = 1 bolígrafo × $ 7848/12
$ x = $654
b) Área de un triángulo ¿9 unidades de base y 6 unidades de altura?
Área de un triángulo =
= 1/2 × Base × Altura
1/2 × 9 × 6
= 27 unidades cuadradas
c) Cien veces la suma de 4.5 con 2.71
Esto se calcula como:
100 × (4,5 + 2,71)
= 100 × (7.21)
= 721

the location of a gas station. Each unit on the graph represents 1 mi. She wants to drive to the gas station
using a straight line. How far is the gas station from Angelica’s house? Show your work.
Answer:
im guessing 11 miles but im not sure
Step-by-step explanation:
Answer:
Answer:
Distance between Gas Station and House = 7.81 miles.
Step-by-step explanation:
Given: House location ( 4, 3 ) and Gas station location ( 10, 8)
On graph 1 unit = 1 mile.
To find: Distance between Gas Station and House
We use the Distance formula to find the distance between two points
From given points and formula,
=
=
= units
Since, 1 unit = 1 mile
⇒
Therefore, Distance between Gas Station and House = 7.81 miles
