Answer:
x = -6/7
Step-by-step explanation:
We must substitute in the values and solve for x
[tex]r = 7x + 7y\\(8) = 7x + 7(2)\\8 = 7x + 14\\8 - 14 = 7x + 14 - 14\\-6 = 7x\\-6/7 = 7x/7\\x = -6/7[/tex]

Three paintings are shaped like an 8-foot square a 7-foot by 4-foot rectangle and a triangle with 6-foot base and height of 7 feet. If those paintings are hung together on the outside of the building how much of the building s wall they cover together ?
Answer:
113 square feet
Step-by-step explanation:
the total area covered can be determined by adding the area of the rectangle, triangle and square together
Area of a square = length² = 8² = 64 ft²
Area of a rectangle = length x width = 7 x 4 = 28 ft²
Area of a triangle = 1/2 x base x height = 1/2 x 6 x 7 = 21 ft²
64 + 28 + 21 = 113 ft²

Angel está adaptando un espacio para hacer actividades recreativas en casa y quiere rodear el borde con plantas, cuántos metros mide el borde si la ecuacion para calcularlo es 2a+2b, donde a representa el ancho y b el largo del espacio, a=1 metro y b=2 metros
Answer:
El borde mide 6 metros.
Step-by-step explanation:
Sabemos que la ecuación para el borde está dada por:
borde = 2*a + 2*b
Si sabemos que:
a = 1 metro
y
b = 2 metros
podemos simplemente remplazar esos valores en la ecuación para el borde, asi obtendremos:
(es decir, donde hay una "a" en la ecuación, escribimos "1 metro", y end donde hay una "b" en la ecuación, escribimos "2 metros", luego resolvemos)
borde = 2*(1 metro) + 2*(2 metros) = 2 metros + 4 metros = 6 metros.
Podemos concluir que el borde mide 6 metros.

1)A pitcher throws a ball at 40.0 m/s, and the ball is electronically timed to arrive at home plate 0.4625 s later. What is the distance from the pitcher to the home plate?
2) radio signal travels from the earth and through space at a speed of 300,000 km/s. How far into space would the signal travel in 80 seconds?
3) bullet leaves a rifle with a speed of 1,230 m/s. How much time elapses before it strikes a target 5000m away?
Will give a brainliest if you are correct
Answer:
the answer to number one is 18.5. i'm not sure about two or three, sorry.
Step-by-step explanation:
1. I think you can use the formula for speed:
speed = distance / time
2. Transpose the equation to find distance and you'll get:
distance = speed x time
3. Substitute the given inputs...
distance = (40 m/s)(0.4625s)
4. Cancel "s".
distance = (40m)(.4625)
5. Calculate.
distance = 18.5 m -- ANSWER
1) The distance be 18.5 meter.
The Velocity of ball is v = 40.0 m/s and it taking t = 0.4625 seconds to arrive at home plate.
What is the relation between velocity, distance and time?
Velocity equals distance travelled divided by the time it takes to get there.
Now,
Velocity = distance/ time
So, Distance = time x velocity
⇒ Distance = 0.4625 x 40.0
= 18.5 m
Thus, the distance be 18.5 meter.
2) Distance of the signal travel is [tex]24 *10^{6}[/tex] [tex]km/sec^{2}[/tex].
Here, Speed of radio signal is 300,000 km/s
Time taking in travel is 80 second.
Speed = distance/ time
Distance = speed x time
= 300,000 x 80
= 24,000,000
Hence, Distance of the signal travel is [tex]24 *10^{6}[/tex] [tex]km/sec^{2}[/tex].
3) Time taking to elapses before it strikes a target is 4.06 second.
Here, Speed of bullet is 1230 m/s
Distance travel by bullet is 5000m
Now,
Speed = distance/ time
Time = distance / speed
= 5000/1230
= 4.06 second
Hence,
Time taking to elapses before it strikes a target is 4.06 second.

Write a quadratic function in standard form whose graph satisfies the given conditions.
passes through
0, 0 , 2, 4 , and 4, 0
Answer:
y = -x² + 4xStep-by-step explanation:
The standard form:
y = ax² + bx + cPairs given:
(0, 0), (2, 4), (4, 0)Substitute values of x and y and work out the values of a, b and c.
1. Point (0, 0)
0 = a(0)² + b(0) + c ⇒ c = 02. Point (2, 4)
4 = a(2)² + b(2) ⇒ 4a + 2b = 4 ⇒ 2a + b = 2 ⇒ b = 2 - 2a3. Point (4, 0)
0 = a(4)² + b(4) ⇒ 16a + 4b = 0Substitute b and solve for a:
16a + 4(2 - 2a) = 016a + 8 - 8a = 08a = -8a = -1Find b:
b = 2 - 2(-1) = 2 + 2 = 4The function is:
y = -x² + 4x

A scaled drawing of May’s room is a square with an area of 16 square inches. If her actual bedroom has a side length of 12 ft, what is the scale of the drawing? 1in = _____ ft
Answer:
9 ft
Step-by-step explanation:
your area in the model is 16 in, and to get area you do LxW or BxH same thing. The room is a square, which means all sides are going to be 12ft. multiply 12 by 12=144 now you have
16in=144ft
then you divide 144 by 16 and get 9.
1in=9ft
