Which equation represents a line which is perpendicular to the line y=-\frac{1}{8}x+3
Answer:
An equation with -8 as the slope.
Step-by-step explanation:
I can't see your choices but you need to look for an equation in which the slope is -8. A line with an opposite reciprocal slope is needed in order to be perpendicular to the line y = 1/8x + 3. The opposite reciprocal of 1/8 is -8.
Does anyone know how to solve this?
Answer:
Perimeter = AB + AC + BC = 26.55 units
Step-by-step explanation:
The perimeter of a triangle is the sum of lengths of all sides.
Here we have a right triangle, right-angled at C
angle B = 46°
AB = 11
We continue to calculate
AC = (11)sin(46°) = 7.91
BC = (11)cos(46°) = 7.64
Perimeter = AB + AC + BC = 26.55 units

Answer:
x-5
x-2
Step-by-step explanation:
Questions 1:
√(x²-10x+25)
x²-10x+25= (x-5)²
√(x-5)²= x-5
question 2:
x²-4x+4= (x-2)²
√(x-2)²= x-2
Which shows the correct solution of the equation
I think just only A is the correct answer
Hey all! This is the another one, pls show the working......
Answer:
Hi again, I'm here to answer!
The correct answers:
10. x = -7 2/3
11. x = 2
12. x = 3
Step-by-step explanation:
(x + 3)/2 = (x - 4)/5
(5x + 15)/10 = (2x - 8)/10
3x/10 = -23/10
x = -23/3
x = -7 2/3
(2x - 1)/3 = x/2
(4x - 2)/6 = 3x/6
x/6 = 2/6
x = 2
(3x + 1)/5 = 2x/3
(9x + 3)/15 = 10x/15
-x/15 = -3/15
x = 3
Hope this helped!

Answer:
Henry had 12 cans of Xtreme diet soda, if he drinks 2 sodas each hour and ends up with 8 cans at the end of the day, how many hours did he drink?
Step-by-step explanation:
12-2h=y
y=8 and your final amount
h = hrs and your variable
12 is your constant! he only has 12 cans, which cannot change
2 is your coefficient, but you can change it to whatever you want

1. Shaded area is 14 cm. Find r to the nearest 0.01 cm.
Answer:
Step-by-step explanation:
Area of the quarter circle = 1/4 pi * r^2
Area of the quarter circle = 1/4 * 3.14 * r^2
Area of the triangle = 1/2 r * r = 1/2 r^2
Equation of Solution
1/4 3.14 * r^2 = 14 cm^2 + 1/2 * r^2 Subtract 1/2 r^2 from both sides
0.785 r^2 - 0.5 r^2 = 14 cm^2 Combine the left
0.285 r^2 = 14. cm^2 Divide by 0.285
r^2 = 14/0.285
r^2 = 49.1228 Take the square root of both sides
sqrt(r^2) = sqrt(49.1228)
r = 7.01

A basketball coach had her team practice free throws. The team attempted 308 free throws altogether. They made 6 times as many free throws as they missed. How many free throws did the team miss?
Let the number missed = x
They made 6 times that amount which would be 6x
The total of missed and made is 308:
X + 6x = 308
Combine like terms
7x = 308
Divide both sides by 7
X = 44
They missed 44
Write the equation of the graph below.
Answer:
-x²+8x-15
Step-by-step explanation:
There are two solutions: 3 and 5
First, let's write the equation in this form (pay attention, the parabola here is going up so it won't be like your graph):
(x-3)(x-5)
For resolve our problem, let's re-write it with a minus before:
-(x-3)(x-5)
You can also expand it and the result will be like this:
-x²+8x-15

what is the solution to this system of linear equations 2x +y =1 3x -y= -6
Answer:
x= -1 y=3
Step-by-step explanation:
Answer:
x = -1
y = 3
Step-by-step explanation:
2x +y =1 3x -y= -6
Add the two equations together to eliminate y
2x +y =1
3x -y= -6
------------------
5x = -5
Divide by 5
5x/5 = -5/5
x = -1
2x+y = 1
2(-1) +y = 1
-2 +y =1
Add 2 to each side
y = 1+2
y =3

Pls help meeeeeeeeeeeee
Answer:
A = 8
B = 6
C = 4
D = 7
Top = 29
Side = 20
Step-by-step explanation:
To get A on the bottom side row you divide 32 by 4 and get 8.
To get D, on the first side row, subtract A, 8, now it's 21, 21 divided by 3 is 7.
To get B, on the first top row, subtract A and D, now divide by 2 and you get 6.
To get C, on the third side row, subtract B and divide by 2 and you get 4.

9514 1404 393
Answer:
n = 24
Step-by-step explanation:
Multiply the given equation by the product of denominators. Then subtract 6n and go from there.
[tex]\dfrac{6}{n-6}=\dfrac{8}{n}\\\\6n=8(n-6)\qquad\text{rid of fractions}\\\\0=2n-48\qquad\text{subtract 6n, simplify}\\\\0=n-24\qquad\text{divide by 2}\\\\\boxed{24=n}\qquad\text{add 24}[/tex]
_____
Alternate solution
Any proportion can be written 4 ways. If we write this one "sideways," we have ...
6/8 = (n -6)/n
1 -1/4 = 1 -6/n . . . . . expand in parallel fashion
6/n = 1/4 . . . . . . . . subtract 1, multiply by -1
n = 24 . . . . . . . . . multiply by 4n
__
Another alternate solution (can be done mentally)
The above "sideways" proportion can be reduced to ...
3/4 = (n -6)/n
The difference between values on the left is 1 unit. On the right, the difference between values is 6. (The numerator is 6 less than the denominator.) The denominator on the left (4) is 4 times the difference, so the denominator on the right (n) will likewise be 4 times the difference: n = 4·6 = 24. Check: 3/4 = 18/24.

What is the measure of angle 4 if angle 1 = 76 degrees, angle 2 = 27 degrees and angle 3 = 17 degrees
Answer:
Step-by-step explanation:
∠1 + ∠2 + ∠3 + a = 360 {Sum of all angles of quadrilateral}
76 + 27 + 17 + a = 360
120 + a = 360
a = 360 -120
a = 240°
a + ∠4 = 360
240 + ∠4 = 360
∠4 = 360 - 240
∠4 = 120°

The question is.. "The expression 5(3r - 10) means the product of 5 and the difference of three times r minus 10. If r = 4, the value of the expression is [?] This is 6th grade math and im kinda stuck here
Answer:
10
Step-by-step explanation:
5(3r - 10)
Let r = 4
5(3*4 - 10)
5( 12 - 10)
5 (2)
10
Answer:
10
Step-by-step explanation:
5(3r-10)
5(3(4)-10)
so forget the 5 and solve inside first
3*4= 12
12-10= 2
now bring the 5 back and multiply

Answer:
8 x 8 = 64
64 x 6 = 384 ft^2 is your answer.
Answer:
384 Sq ft
Step-by-step explanation:
multipliy 8 by 8 to get the area of one side. then because it is a cube, and all the side lengths are the same, you can just multipliy the area of one face by the amount of faces total.
8×8=64
64×6=384
384 ft²
or
384 Sq ft
