Answer:
x = -5
y = -6
Step-by-step explanation:
5x - 6y = 11
-7x + 5y = 5
We could eliminate the 'y' by multiplying the first equation by 5 and the second equation by 6 to get the following:
5(5x - 6y) = 11(5) → 25x - 30 y = 55
6(-7x + 5y) = 5(6) → -42x + 30y = 30
Now we can add the two equations to get:
-17x = 85
x = -85/17 which is x = -5
Now we can plug in -5 into the first equation to solve for 'y':
5(-5) - 6y = 11
-25 - 6y = 11
-6y = 36
y = -6
CHECK:
-7(-5) + 5(-6) should equal 5
35 + (-30) = 5
5 = 5

Math help
would like to know how to do it step by step and answer
Answer:
0.01085 ~ 1.085%
Step-by-step explanation:
Okay so a simple way to do these probability ones is to add an extra space around each side
YES NO
POSITIVE 325 2 _____
NEGATIVE 16 1131 _____
_____ _____ _____
Now in these spaces add all the the rows and columns accordingly
YES NO
POSITIVE 325 2 _327_
NEGATIVE 16 1131 _1147_
_341_ _1133_ _1474_
Now the number in the place where the additional rows meet is your total number of patients, so this is what you would use for your probability.
So we are looking for YES / NEGATIVE which is 16
Now do 16 divided by 1474 and your probability comes out to 0.01085..., so as a percentage, would be 1.085%
Hope that helped :)
What is the ratio of the number of beaks to the number of legs the chickens and the sheep have on this farm?
Answer: 1:9
Step-by-step explanation:
If you multiply 2 legs times 8 chickens we get 16
If you multiply 4 legs times 14 sheep we get 56
The number of legs is 16+56=72
So you have 8 beaks and 72 legs or 8:72
Divide both sides by 8 to simplify and you get 1:9 as the answer
does any one know the Inequality Notation for this [9,∞)
Answer:
x>=9
Step-by-step explanation:
so, we can plot this on a number line
the point at 9 is a solid dot, since brackets (not parenthasis) indicates that we including the number. the shaded part of the line extends all the way to positive infinity. the shaded part means that it is a solution, while the un-shaded parts aren't solutions to [9,infinity) it is x>=9 and not x>9 because 9 is included.
x>=9 is the answer

This makes statement B true.
(81)¾ - (27)⅓
\3 × 2³
Answer:
I won't tell you the answer but if you read the solution, you would understand it.
Step-by-step explanation:
81^3/4 is basically 3 times the fourth root of 81. What number multiplies 4 times to make 81? Then multiply that by 3.
Now we have the cube root of 27. If you have a fractional exponent with no numerator, that just means square root, cube root, fourth root.
Eg. the exponent 1/4 would just mean fourth root
Eg. The exponent 1/2 would just mean square root
The cube root of 27 is 3.
The denominator is 3 times 2 to the third power.
PEMDAS
Order of Operations tells us we do exponents first so 2 to the third power is 8 and multiply by that 3.
You have all the information you need. Now just use your arithmetic skills! Let me know if you need more help.

Perpendicular lines have the product of their gradient equal to -1
For L1,the gradient is 3
For L2,we express in slope-intercept form
6y=1-2x
y=1/6-⅓x
The slope is -⅓
Now product of both slopes 3×-⅓=-1,thus the lines are perpendicular

Solve step by step:
What is the equation of a line that is perpendicular to the line y=2x+1 and passes through the point (4,6)?
Answer:
y = - [tex]\frac{1}{2}[/tex] x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 1 ← is in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex] , then
y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (4, 6 ) into the partial equation
6 = - 2 + c ⇒ c = 6 + 2 = 8
y = - [tex]\frac{1}{2}[/tex] x + 8 ← equation of line

I WILL GIVE BRAINIEST, PLEASE HELP
Answer:
A = (1, 10)
B = (4,10)
C = (4, 14)
D = (1, 16)
Step-by-step explanation:
Okay, so first, we move, or translate the quadrilateral PQRS down -8 spaces on the graph, turning old points:
P (1, -2) = (1, -10) Q (4, -2) = (4, - 10) S (1, -8) = (1, -16) and R (4, -6) = (4, -14)
Now, we need to rotate this new box into -x, y. So our new points are:
(1, -10) = (-1, 10) (4, -10) = (-4, 10) (1, -16) = (-1, 16) and (4,-14) = (-4, 14)
Now we're reflecting off the y-axis, making our x change. So for our final points:
A(1, 10) B (4,10) D(1, 16) and C(4, 14)
Hope this helps! Please check my math and comment wether this worked or not! :)

If given 5 miles is 8km convert 13.5 miles into km
Step-by-step explanation:
There are 2 ways we can do this. We can use our friend which we will call a special device or we could actually solve using formulas we already know. Today, I will be using a formula but you can easily just use the secret device.
Step 1: Knowing the formula which is multiply miles by 1.609 and then round to the nearest tenth or hundredth.
13.5 X 1.609 = 21.7215.
Round down to 21.7.
Final Answer: 21.7 Km is equal to 13.5 miles or vice versa.
A coin was tossed 80 times, out of which it landed on heads 60 times. What is the relative frequency of the coin toss resulting in tails?
Answer : 25%
Step-by-step explanation : If a coin was tossed 80 times and it landed 60 times, 80 - 60 = 20 so 20/80 were tails, let's convert that into % so 20 is 1/4 of 80 so 25%.
Consider this function.
h(x) = (x - 2)^2+3
Which of the following domain restrictions would enable h(x) to have an inverse function?
a. x < 1
b. x ＞5
c. x < 3
d. x > 4
(Ps: all four answer and larger equal then or smaller equal then
Answer:
No inverse function: (a), (b), (c)
Inverse function exists: (d)
Step-by-step explanation:
The graph of h(x) = (x - 2)^2 + 3 is a parabola that opens upward and has vertex at (2, 3). If the entire graph is drawn, and the horizontal line test then applied, h(x) would not have an inverse, because the horizontal line would intersect the parabolic graph twice.
Note that if we restricted the domain to x ≥ 2, the resulting graph would pass the horizontal line test. This would also be true for x ≥ 3, x ≥ 4, and so on. Not so for (a) x < 1. False for x > -5. True for x < 3. True for x > 4.
No inverse function: (a), (b), (c)
Inverse function exists: (d)
Question 3 "Try Again." Mary needs 3 feet of boondoggle for a craft project.
Boondoggle costs $0.25 per inch. How much will the project cost Mary?
Answer:
$9.00
Step-by-step explanation:
We can use conversion factors to solve this equation. The multiplication sequence that I got is shown below:
[tex]\frac{3ft}{1}[/tex] × [tex]\frac{12 in}{1ft}[/tex] × [tex]\frac{0.25}{1in}[/tex]
Our feet and inches cancel out and we get the final expression [tex]\frac{3*12*0.25}{1}[/tex], which is equal to 9, or $9.00.
Hopefully that was helpful! :)
