Answer:
x = 121
Step-by-step explanation:
In order to solve for "x" you need to get it on one side by itself. To do that you need to add 93 to the other side. 93 + 28 is 121.
Answer:
121
Step-by-step explanation:
x-93=28
x=28+93
x=121

Answer:
The answer is [10+(9x3]+4 and 5x4+(7x3).
Step-by-step explanation:
I can't really explain, but if you add 10+4, it'll be 14.
If you multiply 9x3, it'll be 27.
So, if you add 27+14, it will be 41.
For the second answer:
If you also multiply 7x3, it'll be 21. If you ALSO multiply 5x4, its 20. So if you add 20+21, it will equal 41.
please help me, choose the right one

solve the equation for y-value and choose whether it is a direct variation or inverse variation.
xy=7
a) y=7/x direct variation
b) y=x/7 direct variation
c) y=x/7 inverse variation
d) y=7/x inverse variation
Given:
The equation is [tex]xy=7[/tex].
To find:
Whether the given equation is a direct variation or inverse variable.
Solution:
Direct variation: y is directly proportional to x.
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
Inverse variation: y is inversely proportional to x.
[tex]y\propto \dfrac{1}{x}[/tex]
[tex]y=\dfrac{k}{x}[/tex]
Where, k is the constant of proportionality.
We have,
[tex]xy=7[/tex]
Divide both sides by x.
[tex]y=\dfrac{7}{x}[/tex]
It is in the form of inverse variation.
Since [tex]y=\dfrac{7}{x}[/tex] and it is inverse variation, therefore the correct option is (d).

Work out the sizes of angles a, b and c.
b=

+
Answer:
a=21°b=70°c=89°
Step-by-step explanation:
a=21°[by vertical opposite angle]
b+110°=180°[by linear angle]
b=180°-110°=70°
a+b+c=180°[by sum of all angle]
21°+70°+c=180
91°+c=180°
c=180°- 91°
c=89°
To find the sizes of angles a, b, and c, we need to use the properties of straight lines and angles. Since angles on a straight line add up to 180 degrees, we have: Angle a = 21°, Angle b = 159°, Angle c = 159°
Angle b: We know that the sum of angles on a straight line is 180°. Angle b and angle a are on a straight line, so we can write the equation:
b + a = 180°
Given that angle a is 21°, we can now solve for angle b:
b + 21° = 180°
b = 180° - 21°
b = 159°
Angle c: Angles b and c are vertically opposite angles, which means they are equal in measure. So, we have:
c = 159°
Angle a: We already know the measure of angle a:
a = 21°

Step-by-step explanation:
Which function is the inverse of f(x) = -5x -4?
Answer:
f^-1(x) = (x + 4) / -5
Step-by-step explanation:
f(x) = -5x - 4 Substitute f(x) with y
y = -5x - 4 Switch the x and y variables
x = -5y - 4 Solve it down
x + 4 = -5y
y = (x + 4)/ -5
f^-1(x) = (x + 4) / -5 <----- This is the answer
The function t relates the age of a plant fossil, in years, to the percentage, c, of carbon-14 remaining in the fossil relative to when it was alive.
t(c)=-3,970(ln c)
Use function t to complete the statements.
A fossil with 47% of its carbon-14 remaining is approximately ___ years old.
A fossil that is 7,000 years old will have approximately ___ of its carbon-14 remaining.
Applying the logarithmic function, it is found that:
A fossil with 47% of its carbon-14 remaining is approximately 2997 years old.A fossil that is 7,000 years old will have approximately 56.71% of its carbon-14 remaining.The age of a fossil with a proportion c of carbon 14 remaining is given by:
[tex]t(c) = -3970\ln{c}[/tex]
If the fossil has 47% of carbon-14 remaining, we have that [tex]c = 0.47[/tex], and thus:
[tex]t(0.47) = -3970\ln{0.47} = 2997[/tex]
For a fossil that is 7000 years old, we have that [tex]t(c) = 7000[/tex], and hence:
[tex]t(c) = -3970\ln{c}[/tex]
[tex]\ln{c} = -\frac{3970}{7000}[/tex]
[tex]e^{\ln{c}} = e^{-\frac{3970}{7000}}[/tex]
[tex]c = 0.5671[/tex]
A fossil that is 7,000 years old will have approximately 56.71% of its carbon-14 remaining.

The sum of the lengths of the two bases of a trapezoid is 22 cm and its area is 66 cm2.
What is the height of the trapezoid
Answer:
h = 6 cm
Step-by-step explanation:
Given that,
The area of a trapezoid, A = 66 cm²
The sum of the lengths of the two bases of a trapezoid is 22 cm.
We need to find the height of the trapezoid.
The area of a trapezium is given by :
[tex]A=\dfrac{1}{2}\times (\text{sum of parallel sides})\times \text{height}[/tex]
Substitute the values,
[tex]h=\dfrac{2A}{\text{sum of parallel sides}}\\\\h=\dfrac{2\times 66}{22}\\\\h=6\ cm[/tex]
So, the height of the trapezoid 6 cm.
