What is the measure of angle f
Answer:
48°
Step-by-step explanation:
1) The sum of the interior of any triangle is 180°. a + b + c = 180°. We need to find the value of x first before finding the angle F.
2) Substitute the values into a + b + c = 180, where [tex]a=6x-4[/tex], [tex]b =5x-7[/tex], [tex]c=8x-18[/tex].
Hence,
[tex]6x-4+5x-7+8x-18=180\\19x-29=180\\19x=180+29\\19x=209\\x=\frac{209}{19} \\x=11[/tex]
3) Find the angle of F by substituting 11 into x.
[tex]=5(11)-7\\=55-7\\=48[/tex]
Therefore, angle F has a measure of 48°.

give the equation of the horizontal asymptote of the function shown below. g(x)=2x/x+5
Answer:
y=2
Step-by-step explanation:
Because the degrees of the numerator and denominator are equal to each other, then the equation of the horizontal asymptote of the function is y=2 since the end behavior of the function is equal to 2x/x=2.

2x^(3)-3x^(2)+5-3x^(2)+2x^(2)-4x-9
Answer:
2x^(3) - 4x^(2) - 4x - 4.
Step-by-step explanation:
2x^(3)-3x^(2)-3x^(2)+2x^(2)-4x-9
Bring like terms together:
= 2x^(3) - 3x^(2) - 3x^(2) + 2x^(2) - 4x + 5 - 9
Now simplify:
= 2x^(3) - 4x^(2) - 4x - 4.

Write the steps you follow when you want to graph an equation y=2x +3.
Step 1;......
Step 2:.....
Step 3:.....
Answer:
1.Pick the point x= 0, y=3 as your starting point.
2. write the slope as a fraction, in this case 2/1. Move up as many times the numerator says (2), and forward as many times the denominator says (1). If either is negative, you move the opposite direction.
3. You got a second point. Put a ruler between them - or any straight edge - and draw the line.
What’s the next 3 terms of the sequence -2,8,-32?
Answer:
Step-by-step explanation:
This is a geometric series.
First term = - 2
Ratio = second term ÷ first term = 8 ÷ (-2) = -4
Next three terms are:
-32 *(-4) = 128
128*(-4) = - 512
-512*(-4) = 2048
Answer:
The next 3 terms would be 128, -512, 2048
Step-by-step explanation:
Since we are dealing with a Geometric Sequence we use this formula [tex]a_{n}=a_{1} *r^{n-1}[/tex]
Since the first term([tex]a_{1}[/tex]) is -2 and for us to find R we have to divide 8 by -2 = -4
So we would rewrite the equations to find the next three terms as
[tex]a_{4}=-2*-4^{4-1}=-2*-4^3=128[/tex]
[tex]a_{5}=-2*-4^{5-1}=-2*-4^4=-512[/tex]
[tex]a_{6}=-2*-4^{6-1}=-2*-4^5=2048[/tex]

The number 2.31 is 2,200 times greater than 1.05 .
Find the correct value of x and y.
A. x = 10 and y = 30
B. x = 10 and y = 13
C. x = 30 and y = 10
D. x = 13 and y = 10
Answer:
2.31 is not 2,200 times greater than 1.05.
(2,200)(1.05) = 2310
Did you mean 2.200 times greater?

find the slope and y intercept.
Step-by-step explanation:
the most common form of line equation is
y = ax + b
a is the slope of the line. it is expressed as the ratio
y coordinate change / x coordinate change
when going from one point to the other.
b is the y-intercept (the y value when x = 0).
once we have the slope, we get b by using the coordinates of one of the given points as x and y in the equation and since for b.
2 points are marked already :
(-3, 4) (3, -4)
x changes by +6 (from -3 to 3)
y changes by -8 (from 4 to -4)
the slope is -8/+6 = -8/6 = -4/3
the y-intercept is also clearly visible on the chart : the line crosses the y-axis precisely at (0, 0).
so, the y-intercept is 0.
What is the y-intercept of the linear equation x minus one-half y = negative 6? –6 –3 0 12.
Answer:
(0,12) or 12
Step-by-step explanation:
x - 1/2y = -6
When you make x = 0,
-1/2y = -6
y= 12
