Answer:
4
Step-by-step explanation:
8x - 4 = 4x + 12
Add 4 to both sides:
8x = 4x + 16
Subtract 4x from both sides:
4x = 16
Divide by 4 from both sides"
x = 4

A rectangle has one side of 10cm. How fast is the area of the rectangle changing at the instant when the other side is 12 cm and increasing at 3cm per minute
30 is the area of the rectangle changing at the instant when the other side is 12 cm and increasing at 3cm per minute
What is Area of Rectangle?The area of Rectangle is length times of width.
Given,
A rectangle has one side of 10cm
We need to find how fast is the area of the rectangle changing at the instant when the other side is 12 cm and increasing at 3cm per minute
This can be written as A=10x
Now differentiate with respect to t.
dA/dt=10 dx/dt
increasing at 3cm per minute
dx/dt=3
dA/dt=10 (3)
dA/dt=30
Hence 30 is the area of the rectangle changing at the instant when the other side is 12 cm and increasing at 3cm per minute

Solve the equation-10 +1 +7x =37
Answer:
Answer in Explanation
Step-by-step explanation:
-10 + 1 + 7x = 37
-9 + 7x = 37
Add 9 on both sides to leave 7x alone
7x = 46
Divide by 7 to leave x alone
x = 46/7 or 6.57
If the equation is positive 10 at the beginning instead of -10 then this is the answer for that:
10 + 1 + 7x = 37
11 + 7x = 37
Subtract 11 from both sides to leave 7x alone
7x = 26
Divide by 7 to leave x alone
x = 26/7 or 3.7

y = -7x - 21
What is the slope of this equation and what is the Y intercept.
Answer:
Slope is -7
Y intercept = -21
Step-by-step explanation:
The equation is Y=mx+b
M is the slope so -7 would equal the slope
B is where your Y- intercept already is so that would equal -21

b. Solve for x.
D
B
c. Determine the measure of ZABD.
Answer:
Step-by-step explanation:
a) ∠ABD + ∠DBC = 90°
4x - 3 + 7x - 6 = 90
4x + 7x - 3 - 6 = 90
11x - 9 = 90
11x = 90 + 9
11x = 99
x = 99/11
x = 9
∠ABD = 4*9 - 3 = 36 - 3 = 33

La razón que indica el avance de un automóvil a 40,000m en 60 min es 666.67 m/min
Queremos obtener la razón entre la distancia avanzada por un automóvil y el tiempo en el que se avanza esta distancia.
Recordamos que:
velocidad = distancia/tiempo.
Entonces lo que calcularemos es la velocidad, en promedio, del autmóvil.
Tenemos:
distancia = 40,000mtiempo = 60minVelocidad = 40,000m/60min = 666.67 m/min

QUICK!!!! I NEED AN ANSWER!! Emily says that the negative sign means opposite of, so -(-45) means the opposite of negative 45, which is 45. Is Emily correct?
Answer:
Yes, Emily is correct.
Step-by-step explanation:
If you have a - sign in front of a number in parenthesis that is negative, then what you are doing is taking the opposite of that negative number. Remember that the opposite of a negative number is a positive number. In this case, we want the opposite of negative five. What is that? It is +45, or 45. So yes, Emily is correct.

Answer:
[tex]\frac{4}{6}+\frac{3}{5}[/tex]
Step-by-step explanation:
1 + [tex]\frac{8}{30}[/tex] = [tex]\frac{30}{30}[/tex] + [tex]\frac{8}{30}[/tex] = [tex]\frac{38}{30}[/tex] = [tex]\frac{19}{15}[/tex]
[tex]\frac{3}{6}[/tex] + [tex]\frac{3}{5}[/tex] = [tex]\frac{3.5}{6.5} + \frac{3.6}{5.6}[/tex] = [tex]\frac{15}{30} + \frac{18}{30} = \frac{33}{30}[/tex] = [tex]\frac{11}{10}[/tex]
[tex]\frac{4}{6} + \frac{3}{5} = \frac{4.5}{6.5} + \frac{3.6}{5.6} = \frac{20}{30} + \frac{18}{30}[/tex] = [tex]\frac{38}{30}[/tex] = [tex]\frac{19}{15}[/tex]
[tex]\frac{4}{6} + \frac{4}{5} = \frac{4.5}{6.5} + \frac{4.6}{5.6} =\frac{20}{30}+\frac{24}{30}[/tex] = [tex]\frac{44}{30}[/tex] = [tex]\frac{22}{15}[/tex]
[tex]\frac{5}{6}+\frac{1}{5}=\frac{5.5}{6.5}+\frac{1.6}{5.6}=\frac{25}{30}+\frac{6}{30}=\frac{31}{30}[/tex]

[tex]4x^2 - 3[/tex] [tex]4(-10)^2 - 3[/tex] [tex]4(100)-3[/tex] [tex]400-3[/tex] [tex]397[/tex]Therefore, the answer is 397.
Noir drove from the Dead Sea up to Amman, and her altitude increased at a constant rate. When she began driving her altitude was 400 meters below sea level. When she arrived in Amman 2 hours later, her altitude was 1000 meters above sea level. Let y represent noir’s altitude in meters relative to sea level after x hours.
Answer:
y(x) = -400 m + (700 m/hr)x
Step-by-step explanation:
Let y = 0 represent sea level. Noir's initial altitude was -400 m. In two hours she went from -400 m to +1000 m, a positive change of 1400 m. Thus, the rate of ascent was m = slope = (change in altitude) / (change in time), or
rate of ascent = 1400/2 m/hr = 700 m/hr
Thus, an equation describing her altitude relative to sea level after x hours is
y(x) = -400 m + (700 m/hr)x, where x is the number of hours of driving completed. This formula correctly predicts the altitude after two hours:
y(2) = -400 m + (700 m/hr)(2 hr) = 1000 m above sea level.

Find the equation of the line L.
Answer:
y = ([tex]-\frac{1}{2}[/tex])x + 4
Step-by-step explanation:
(x1,y1) = (0,4) ; (x2,y2) = (8,0)
The equation will look like y=mx+b
Slope m = [tex]\frac{rise}{run}[/tex] = [tex]\frac{y2-y1}{x2-x1}[/tex] = [tex]\frac{0-4}{8-0}[/tex] = [tex]\frac{-4}{8}[/tex] = [tex]-\frac{1}{2}[/tex]
Next, substitute either x1y1 or x2y2 (it's gonna give the same answer anyways) and m to the equation y=mx+b to find b.
y=mx+b
0 = ([tex]-\frac{1}{2}[/tex])8 + b
0 = -4 +b
0+4 = -4 +4 +b
b=4
Then substitute b and m to the equation y=mx+b
y = mx + b
y = ([tex]-\frac{1}{2}[/tex])x + 4

Answer:
In this this construction reflections is present on the 2 line posts by the side. Why I say this is because the line post on the right reflected or translated to the right. Also the little line in the middle was a rotation and dilation, to stay between the posts. So this is why this stool took a translations, reflections, and rotations.
