Answer:
z = -2
Step-by-step explanation:
7z + 4 - 9z = 8 (The first step is to combine like terms, so 7z -9z = -2z)
-2z + 4 = 8 (Subtract 4 on each side)
-2z = 4 (Divide each side by -2)
z = -2
You can plug -2 back in to check, and you get:
7(-2) + 4 -9(-2) = 8
-14 + 4 + 18 = 8
8 = 8
Hopefully, this helped. Good luck!
Answer:
z=-2
Step-by-step explanation:
7z+4-9z=8
7z-9z=8-4
-2z=4 divide by-2
z=-2

What is the distance between (2,3) and (-2,7)? Round to the nearest tenth
Answer:
Step-by-step explanation:
distance = [tex]\sqrt{(7-3)^2+(-2-2)^2[/tex] = [tex]\sqrt{16+16} = \sqrt{32}[/tex], which is approximately 5.65685
Answer:
5.7
Step-by-step explanation:
[tex] \sqrt{(2 + 2) {}^{2} + (3 - 7) {}^{2} } = \sqrt{ {4}^{2} + {4}^{2} } = \sqrt{16 + 16} = \sqrt{32} = 4 \sqrt{2} = 5.7[/tex]

A person places $73700 in an investment account earning an annual rate of 5.5%, compounded continuously . Using the formula V = P * e ^ (rt) , where V is the value of the account in t years, P is the principal initially invested , e is the base of a natural logarithm, and r is the rate of interest, determine amount of money, to the nearest cent , in the account after 11 years .
Answer:
The amount in the account after 11 years is $134,963.29
Step-by-step explanation:
Here, we want to determine the amount in the account after 11 years
What we have to do here is to substitute P for the amount invested which is $73,700
r is the rate given as 5.5% = 5.5/100 = 0.055
t is the time given as 12 years
substituting these values, we have;
V = 73,700 * e^(12* 0.055)
V = $134,963.29

Answer:
The equation that matches the function shown is option;
C. [tex]y = sin\left (\dfrac{1}{2} \cdot x\right)[/tex]
Step-by-step explanation:
The given graph of the function is a sinusoidal graph
The values of 'x' and 'y' coordinates at the maximum, x-intercept and minimum points are given as follows;
x, [tex]{}[/tex] y
0 [tex]{}[/tex] 0
π [tex]{}[/tex] 1
2·π [tex]{}[/tex] 0
3·π [tex]{}[/tex] -1
4·π [tex]{}[/tex] 0
We note that sin(π/2) = 1, sin(π) = 0 sin(3·π/2) = -1, and sin(4·π/2) = sin(2·π) = 0
Therefore;
y = the sine of half the x-value
Which is presented as follows;
[tex]y = sin\left (\dfrac{1}{2} \cdot x\right)[/tex].

un campo de futbol tiene 100m de largo y 60m de ancho¿ Cuales son la longitud y la anchura del campo?
Answer:
328 pies de largo
196.8 pies de ancho
Step-by-step explanation:
Ya que las medidas dadas estan en metros, podemos usar esas medidas para calcular la longitud y anchura en pies.
100 metros de largo.
60 metros de ancho.
Si sabemos que 1m es igual a 3,28 pies, simplemente tenemos que multiplicar las medidas en metros por 3.28 y nos va dar la medida del campo en pies.
100 * 3.28 = 328 pies de largo
60 * 3.28 = 196.8 pies de ancho

ERROR ANALYSIS Describe the error in determining whether the lines are parallel, perpendicular, or neither.
Line 1: (3,-5),(2, -1)
Line 2: (0,3),(1,7)
There is a sign error in finding m
The slopes of perpendicular lines are negative reciprocals of each other.
Two lines are parallel when their slopes have the same absolute value.
In Line 2, one point is on the x-axis, so only the y-values should be subtracted to find the slope.

a football team gains 9 1/2 yards on their first play then lose 10 yards for a penalty they lose 5 yards and then gain 7 yards on the next two plays what is the teams overall gain or loss and did rhey make a first down (10+ yards)?
Answer: No
Step-by-step explanation: Because if the team lost 10 yards from 9 1/2 then they would be negative yards if they lose 5 yards they will have 5 1/2 and if they gain 7 yards their total will be 1.5 so they never made it to 10+ yards.
A farmer planted corn in a square field. One side of the field measures 37 yards. What is the area of the cornfield
Answer:
1,369 cm^2
Step-by-step explanation:
A square is a two-dimensional shape with four right angles and four equal sides.
This means each and every side is equal.
In this case, every side is 37 yards.
To find the area of a square, simply multiply a length of a side by itself.
Like this,
37⋅37 = 1,369.
Therefore, the area of the cornfield is 1,369 yards cm^2.
