Answer:
y = -8
Step-by-step explanation:
y = 3
is a "flat" horizontal line, which means every point on that line has the same y value no matter what x value we would consider.
any line parallel to that is then also a horizontal line with a constant y value. which y value ? well, the y coordinate of the given point tells us : (-2, -8)
so, the line equation is
y = -8
Answer:
C, y=-8
Step-by-step explanation:
Which equation represents the line that is parallel to y= 3 and passes through (-2,-8)?
y=3 means the y value is always 3, so the line is horizontal and parallel to the y axis.
A, x= -2 this is a vertical line
B. x= 3 this is a vertical line
C, y=-8 this is a horizontal line, where y is always -8 so it is parallel and will pass through -2
D, y= 3x-2 this line will be at an angle
How many degrees is 5/12?
Answer:
The answer is 22 point 62 degrees.
which equation represents a line that is parallel to the line whose equation is 2y=3x+7 ?
1) y=x+7
2) 2y=3x-3
3) y=2/3x-3
4) y=3/2x-3
in the figure below, a line intersects two parallel lines. Fill in the missing angle measurements and explain how you solved for the measurement by naming the angle relationship with a second angle that helped you.
The value of the angle measures as required is;
<a = 125°<b = 55°<c = 125°<e = 125°<f = 55°<h = 55°Vertically opposite angles and Sum of angles on a straight lineVertically opposite angles otherwise referred to as X-angles are angles opposite each another at the point of intersection of two line and hence, are equal.

Solve 1 over 25 = 5^(x+4)
A. -7/2
B. -6
C. 9/2
D. 2
Answer:
[tex]\boxed{\underline{\tt B.\:x=-6}}[/tex]
Step-by-step explanation:
[tex]\tt \cfrac{1}{25} = 5^{(x+4)}[/tex]
(First, let's convert both sides to the same base):-
[tex]\tt 5^{-2}=5^{x+4}[/tex]
(Now, cancel the base of 5 on both sides):-
[tex]\tt -2=x+4[/tex]
( Subtract 4 from sides)
[tex]\tt x+4-4=-2-4[/tex]

Diego and Lin are drinking milkshakes. Lin starts with 12 ounces and drinks
per second. Diego starts with 20 ounces and drinks į an ounce per second.
1. How long will it take Lin and Diego to finish their milkshakes?
Answer:
Lin=48 seconds Diego=30 seconds
Step-by-step explanation:
Answer:
Lin 48 seconds Diego 30 seconds
Step-by-step explanation:
Lin ----- 48 seconds
Diego---------30 seconds
Lin ---------- 12 ounces ÷ (1/4) ounces/second = 12 ÷ (1/4) = 48 seconds
Diego --------- 20 ounces ÷ (2/3) ounces/second = 20 ÷ (2/3) = 30 seconds

George is reading a book. On Monday he reads 1/3 of the book. On Tuesday he reads three - tenths of the remaining pages. He has 35 pages left to read.
How many pagesare in the book?
Answer: 75 pages
Step-by-step explanation:
3/10 of 2/3
= 3/10 * 2/3
= 2/10; simplified by dividing by 2 = 1/5
1/3 + 1/5 = 8/15
Let x represent the amount of pages left
so, 7/15 x = 35
x = 75
Therefore, there are 75 pages in the book
Write an exponential function in the form y=ab^x that goes through points (0, 20) and (7, 2560).
Answer:
[tex]y = 20\times 2^{x}[/tex].
Step-by-step explanation:
Let [tex]y = (a)\, (b)^{x}[/tex] denote this exponential function for some constant [tex]a[/tex] and [tex]b[/tex] ([tex]b > 0[/tex]) that need to be found.
Assume that the graph of the function [tex]y = (a)\, (b)^{x}[/tex] goes through the point [tex](x_{0},\, y_{0})[/tex]. Substituting in [tex]x = x_{0}[/tex] and [tex]y = y_{0}[/tex] should satisfy the equation of this function:
[tex]y_{0} = (a)\, (b)^{x_{0}}[/tex].
For example, [tex]y = (a)\, (b)^{x}[/tex] goes through the point [tex](0,\, 20)[/tex]. Substituting in [tex]x = 0[/tex] and [tex]y = 20[/tex] should then satisfy the equation of this function:
[tex]20 = (a)\, (b)^{0}[/tex].
Similarly, since the graph of this function goes through [tex](7,\, 2560)[/tex] where [tex]x = 7[/tex] and [tex]y = 2560[/tex]:
[tex]2560 = (a)\, (b)^{7}[/tex].
In general, the constant [tex]a[/tex] in such systems could be eliminating by dividing one equation by the other. For example, dividing [tex]2560 = (a)\, (b)^{7}[/tex] by [tex]20 = (a)\, (b)^{0}[/tex] gives:
[tex]\displaystyle \frac{2560}{20} = \frac{(a)\, (b)^{7}}{(a)\, (b)^{0}}[/tex].
Simplify to obtain:
[tex]\displaystyle 128 = b^{7 - 0}[/tex].
[tex]\displaystyle 128 = b^{7}[/tex].
[tex]b^{7} = 128[/tex].
Since the exponent of [tex]b[/tex] is an odd number, the sign of [tex]b[/tex] should also be positive- same as the sign of [tex]128[/tex]. Extra steps would be required if the exponent of [tex]b[/tex] is even.
Raise both sides to the [tex](1/7)[/tex]th power to find the (unique) value of [tex]b[/tex]:
[tex]b = 128^{1/7} = 2[/tex].
Substitute [tex]b = 2[/tex] back into either equation (for example, [tex]2560 = (a)\, (b)^{7}[/tex]) to find the value of [tex]a[/tex]:
[tex]2560 = (a)\, (2)^{7}[/tex].
[tex]\begin{aligned}a &= \frac{2560}{2^{7}} \\ &= \frac{2560}{128} \\ &= 20\end{aligned}[/tex].
Thus, this exponential function would be [tex]y = 20\times 2^{x}[/tex].

asap pleaseeee eeeeee
Answer:
x = 14
Step-by-step explanation:
If the perimeter is 80, then that is (x+6) + (x+6) + (x+6) + (x+6). If you want to find x, you have to get rid of 6. 6+6+6+6 = 24. The perimeter, 80, minus 56. You then divide 56 by 4 to get x. That is 14. To check, you find (14+6)*4. That is 80.
