Step-by-step explanation:
y=-3/4 ÷ -4/3
y=+9/16
Answer:
So we have this equation:
[tex]\frac{-4}{3y}=\frac{-3}{4}[/tex]
We can multiply both sides by 4 and 3y:
[tex]\frac{-4*4*3y}{3y}=\frac{-3*4*3y}{4}[/tex]
[tex]-4*4=-3*3y[/tex]
[tex]-16 = -9y[/tex]
Now we divide both sides by 9:
[tex]\frac{-16}{-9}=y[/tex]
And we can remove the minus signs:
[tex]\frac{16}{9}=y[/tex]
If you mean [tex]\frac{-4}{3}y=\frac{-3}{4}[/tex]:
[tex]-4y*4=-3*3[/tex]
[tex]-16y = -9[/tex]
[tex]y=\frac{9}{16}[/tex]

therefore the answer is c
The exponential equation which rewrites the logarithmic equation is given by 6ˣ = 18
What is Logarithm?The power to which a number must be increased in order to obtain another number is known as the logarithm. A power is the opposite of a logarithm. In other words, if we subtract an exponentiation from a number by taking its logarithm
The properties of Logarithm are :
log A + log B = log AB
log A − log B = log A/B
log Aⁿ = n log A
Given data ,
Let the logarithmic equation be represented as A
Now , the value of A is
log₆ 18 = x
From the properties of logarithm , we get
log Aⁿ = n log A
On simplifying , we get
6ˣ = 18
where the value of x = 1.61314
Hence , the exponential equation is 6ˣ = 18

An elm tree is 3 and one-half times as tall as an apple tree. The apple tree is 10 and two-thirds feet tall. How tall is the elm tree?
Answer:
The elm tree is 40 5/6 inches tall
Step-by-step explanation:
Let
Tallness of the apple tree = x
Tallness of the elm tree= 3 1/2x
Apple tree = 10 2/3 feet tall
Elm tree = 3 1/2x
Where x= 10 2/3
Elm = 3 1/2 (10 2/3)
= 7/2(35/3)
= 7*35 / 2*3
= 245 / 6
= 40 5/6 inches tall
The elm tree is 40 5/6 inches tall

Angle F and angle G are complementary . The measure of angle F is three times the measure of angle G. What is the measure of each angle?
Answer:
[tex]g[/tex] = 22.5°
[tex]f[/tex] = 67.5°
Step-by-step explanation:
Let’s create a system of equations for [tex]f[/tex] and [tex]g[/tex].
Complementary angles are two angles that add up to 90°, so [tex]f+g=90[/tex]
Also, [tex]f[/tex] is thrice of g: [tex]f=3g[/tex]
We can now substitute [tex]3g[/tex] in [tex]f+g=90[/tex] for [tex]f[/tex].
[tex]3g + g = 90\\\\4g = 90\\\\g=22.5[/tex]
Now, we can find [tex]f[/tex] by substituting [tex]g[/tex] into either equation.
[tex]f + 22.5 = 90\\\\f = 90-22.5\\\\f = 67.5[/tex]

Use graphing technology to find the range of the function f(x)=x2 +6x+9
Answer:
See below.
Step-by-step explanation:
Refer to the graph.
The range of a graph is the span of y-values it covers.
From the graph, we can see that the span of y-values is all values greater than or equal to 0.
Therefore, our range is, in interval notation:
[tex][0,\infty)[/tex]
Note that we use brackets with the 0 because 0 is included in our range.
In set notation, this is:
[tex]\{y|y\in\mathbb{R},y\geq 0\}[/tex]
