A 156-inch board is cut into two pieces. One piece is three times the length of the other. Find the
length of the shorter piece.
The shorter piece is inches long.
Answer:
The shorter piece is 39 inches long.
Step-by-step explanation:
ratio = 3 : 1
3+1=4
156/4 = 39
just to check:
39 x 3 = 117 (the lenght of the longer piece)
117 + 39 =156

helppppp plssssss
will give brainy
Answer:
5
Step-by-step explanation:
if the interest is not compounding then it's called simple interest
which is shown through the following equation
PV(1+it)
plug in what we know and get
50(1+.1*1)
50*1.1=55
which means he'll earn 5 dollars interest in one year

Answer:
y = 2x - 3
Yes, your answer is correct.
Step-by-step explanation:
First, find the slope of the two points by using the slope formula:
y2 - y1
m = -------------
x2 - x1
13 - 5
m = -------------
8 - 4
8
m = ------- = 2
4
To find the y-intercept, plug in values into the slope-intercept formula:
y = mx + b
Where m = slope and b= y-intercept. Use any one of the points. I'll be using (4,5):
5 = (2) (4) + b
5 = 8 + b
-3 = b
b = -3
So, putting everything into the slope intercept formula:
y = 2x - 3
8x - y = 42
-4x - 6 = y
Answer:
8x-(-4x-6)=42
8x+4x+6=42
12x=42-6
12x=36
x=36/12
x=3
substitute in an equation of your choice
8(3)-y=42
24-y=42
24-42=y
-18=y
Step-by-step explanation:
Answer:
x= 4 y= -10
Step-by-step explanation:
8x - y = 42
-4x - 6 = y
rearrange -4x - 6 =y to -4x -y = 6
8x - y = 42
-4x - y = 6
4x = 48
48/4 = 12
x=4
subsitute x with 4 adn solve for y = -22
y= -10
The parabola y-- (x – 3)2 + 6 has its focus at (3, 1). Determine and state the equation of the directrix.
Answer: you got to Find the focus of a parabola given its equation. If you have the equation of a parabola in vertex form , then the vertex is at and the focus is . Notice that here we are working with a parabola with a vertical axis of symmetry, so the -coordinate of the focus is the same as the -coordinate of the vertex.

Costco marks up the price of a $500.00 couch by 25%
and then has a 25% off sale. What is the selling price of
the couch?
Answer: 468.75
is ya answer
i think
sorry if im wrong
Answer:
468.75
Step-by-step explanation:
First we need to add 25% to 500.00 which is 625.
Next we need to subtract 25% from 625.
Now we have 468.75.
The selling price of the couch is $468.75.

What is the measure of angle x?
Answer:
43
Step-by-step explanation:
Since right angles are 90 degree. 90 - 47 = 43
It looks mirrored, so I am guessing the 47 degree is also at the bottom.
If I'm wrong, I apologize.

One angle of a right triangle measures 34 degrees. What is the measure of the other acute angle
Answer:
56 degrees
Step-by-step explanation:
we know the right triangle has a 90 degree angle, so we add 90 + 34 to get 124
once we have that down we subtract 124 from 180 to get 56
the reason we subtract from 180 is because the sum of all the angles in a triangle equals 180

Help me ??????????????????
Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
(h, k) are the coordinates of the vertex and a is a multiplier
Given
f(x) = - 2x² - 12x - 16
To complete the square the coefficient of the x² term must be 1
Factor out - 2 from - 2x² - 12x
f(x) = - 2(x² + 6x) - 16
add/ subtract ( half the coefficient of the x- term )² to x² + 6x
f(x) = - 2(x² + 2(3)x + 9 - 9 ) - 16
= - 2(x + 3)² + 18 - 16
= - 2(x + 3)² + 2 ; y = 2
