Given f(x) = 4x − 6 and g(x) = f(2x),
write an equation for g.
g(x) = _______________________
Answer:
1 and 1/3
Step-by-step explanation:
Fx equals 4x-6
Add six to both sides
6 equals 4X
Divide both sides by 4
2/3 equals x
Then GX equals f (2x)
Two times 2/3 is 1 and 1/3
The value of g(x) when f(x) = 4x − 6 and g(x) = f(2x) will be; 1/3
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
We have been given that f(x) = 4x − 6 and g(x) = f(2x), then;
We have to Add six to both sides;
f(x) = 4x − 6
6 = 4X
Now Divide both sides by 4;
2/3 = x
Then G(X ) is equals to f (2x)
Now, 2( 2/3 ) = 1 /3
The value of g(x) when f(x) = 4x − 6 and g(x) = f(2x) will be; 1/3

What is the value of n when 6n-14=3n+7
answer: n=7
work:
6n-14=3n+7
6n-14 (+14) = 3n+7 (+14) add 14 to both sides
6n=3n+21
6n(-3n)=3n(-3n)+21 subtract 3 from both sides
3n=21
3n/3= 21/3 divide by 3 on both sides
n=7
Answer: n = 7
Step-by-step explanation; Simplifying
6n + -7 = 14 + 3n
Reorder the terms:
-7 + 6n = 14 + 3n
Solving
-7 + 6n = 14 + 3n
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-3n' to each side of the equation.
-7 + 6n + -3n = 14 + 3n + -3n
Combine like terms: 6n + -3n = 3n
-7 + 3n = 14 + 3n + -3n
Combine like terms: 3n + -3n = 0
-7 + 3n = 14 + 0
-7 + 3n = 14
Add '7' to each side of the equation.
-7 + 7 + 3n = 14 + 7
Combine like terms: -7 + 7 = 0
0 + 3n = 14 + 7
3n = 14 + 7
Combine like terms: 14 + 7 = 21
3n = 21
Divide each side by '3'.
n = 7
Simplifying
n = 7

Which of the following equations has a positive slope?
y= -x+0
y= x
y= -4
Answer: i say number 3
Step-by-step explanation:
because i pay attention in math class
The equation y = x has the positive slope.
What is Slope?Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.
Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.
Given three equations which are in the form of slope intercept form of the equation of a line.
Slope intercept form of a line is y = mx + d, where m is the value of the slope and d is the value of the y intercept.
y intercept is the y coordinate of the point on the line where it touches the Y axis. The x coordinate will be 0 there.
Equations given are
y = -x + 0 ⇒ Slope = -1
y = x ⇒ Slope = 1
y = -4 ⇒ Slope = 0
So y = x has the slope equal to 1 which is positive.
Hence the equation y = x has the positive slope.

Kara and James both like to mix a little bit of milk with their eggs when they make scrambled eggs. Kara mixes ¾ of a tablespoon of milk with one egg. James mixes 1 ¼ tablespoons milk with two eggs. Is there a proportional relationship between Kara and James’ milk and egg amounts?
Answer:
"No, there is not a proportional relationship."
Step-by-step explanation:
"A proportional relationship is when 2 amounts have the same ratios.
The easiest way to see this is to put them into decimal form.
3/4 is equal to 0.75 (You can find this by dividing 3 and 4 in the calculator)
1 1/4 is equal to 1.25
Kara mixes every 0.75 with 1 egg.
James mixes every 1.25 tablespoons with 2 eggs.
Divide 1.25 by 2 to find out how many tablespoons that James mixes with 1 egg.
1.25 tablespoons /2 = 0.625
2 eggs /2 = 1 egg
Therefore, James mixes 0.625 tablespoons of milk with 1 egg.
They do not mix the same amount of tablespoons of milk for ever ONE egg, meaning that they are not proportional."

Step-by-step explanation:
two angles in a triangle have measures of 62 degrees and 15 degrees. What is the measure of the third angle.
A.92 degrees
B.47 degrees
C.77 degrees
D.103 degrees
Answer:
the answer is 103
Step-by-step explanation:62°+15°=77° degrees
Then it is 180° - 77° degrees
180°-77°=103°
The measure of the third angle of a given triangle is 103°.
Given that the measure of two angles is 62° and 15°.
We need to find the measure of the third angle.
What is the angle sum property of a triangle?The angle sum property of a triangle states that the sum of interior angles of a triangle is 180°.
Let the measure of the third angle be x.
Now, 62°+15°+x=180°
⇒x=180°-77°
⇒x=103°
Therefore, the measure of the third angle is 103°.

Answer:
Angle O = 72°, Angle M = 18°, Angle N = 90°
Step-by-step explanation:
According to the angle sum theorem, all interior angles of a euclidean triangle always add up to 180°.
given 5(Angle M) = Angle N, and 4(Angle M) = Angle O, you can substitute these equations into the equation defined by this theorem, Angle M + Angle N + Angle O = 180°
. Angle M + 5(Angle M) + 4(Angle M) = 180°
10(Angle M) = 180°.
then you divide. Angle M = 18°
with this statement. you can substitute this into the other equations to get the other answers.
5(18°) = Angle N, 4(18°) = Angle O.
90° = Angle N, 72° = Angle O.

(Decimal: 0.792593)
Step-by-step explanation:
Answer:
a. 19/20
B. -5.78
Step-by-step explanation:
Dividing by a fraction is the same as multiplying by its reciprocal. i.e. [tex]\frac{-\frac{2}{3} }{-\frac{8}{9} } =-\frac{2}{3} *-\frac{9}{8} = \frac{3}{4}[/tex] to add to 1/5, change both denominators to 20.
[tex]\frac{3}{4} * \frac{5}{5} = \frac{15}{20}[/tex]
[tex]\frac{1}{5} *\frac{4}{4} =\frac{4}{20}[/tex]
[tex]\frac{15}{20} +\frac{4}{20} = \frac{19}{20}[/tex]
B. Convert all to decimals, then work from the inside out because of the parentheses. -1.6 + 4 = 2.4, 2.4(-0.3) = -0.72, -0.72 - 6.5 = -5.78
