Answer:
x=-1, y=4. (-1, 4).
Step-by-step explanation:
-6x-y=2
-7x-4y=-9
----------------
y=-6x-2
-7x-4(-6x-2)=-9
-7x+24x+8=-9
17x=-9-8
17x=-17
x=-17/17
x=-1

Step-by-step explanation:
A method currently used by doctors to screen for possible bre canc fails to detect canc in 15% of the women who actually have the disease. A new method has been developed that researchers hope will be able to detect canc more accurately. A random sample of 70 women known to have br canc were screened using the new method. Of these, the new method failed to detect can in six.
A. Specify the null and alternative hypothesis that the researchers wish to test.
B. Is the sample large enough
Step-by-step explanation:
1.sample size n = 70
X = 6
We calculate the sample proportion
P^ = 6/70
= 0.0857
The population proportion = 15 percent
P = 15/ 100
= 0.15
The question says we should specify the hypothesis
Null hypothesis
H0: p = 0.15
Alternative
H1: P < 0.15
2.
The sample size is 70 and therefore large enough

Can you prove the triangles below are congruent? Explain why or why not.
Answer: This is kinda confusing but I would say no
Step-by-step explanation: Because they would be congruent if the little line in JKD is in the middle of JK instead of KD.
Answer:
The traingles are not congruent.
Step-by-step explanation:
ang A=ang J
ang L=ang K
LA=KD
So, u must have thaught that the triangles are congruent by ASA. But it's not true.
The Angle-Side-Angle criterion states that the two triangles can only be congruent if two angles and the included side of one triangle are equal to the corresponding two angles and the included side of the other triangle.
But here, the LA is the included side but KD is not. In order to be congruent, LA must congruent to KJ of ∆JKD.
I need help. q – 12 = 1
Answer:
q=13
Step-by-step explanation:
Given q - 12 = 1
we need to find q
to do so we need to isolate the variable using inverse operations
so to get rid of the 12 we add 12 but whatever we do to one side we do to the other
so we add 12 to each side
-12+12 cancels our
1+12=13
we're left with
q=13
Amy is attending physical therapy after knee surgery. She walked 6 1/4 miles over 3 days. How many miles is this per
day? (Simplify the answer and write it as a mixed number)
Answer:
Step-by-step explanation:
2 1/12 miles per day
The number of miles Amy walked per day is given by the equation
A = 2 1/12 miles
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
The total number of miles walked by Amy = 6 1/4 miles
The total number of miles walked by Amy = 25/4 miles
And , the number of days = 3 days
So , the number of miles per day A = total number of miles walked by Amy / number of days
Substituting the values in the equation , we get
The number of miles per day A = ( 25/4 ) / 3
The number of miles per day A = 25/12
The number of miles per day A = 2 1/12 miles
Hence , the equation is A = 2 1/12 miles

A cylinder has a diameter of 10 units.
Its radius is
units. If its height is twice its radius, its height is
units. Its volume is about
cubic units
Answer:
1st blank: 5
2nd blank: 10
3rd blank: 785
Step-by-step explanation:
the radius of a circle or the base/top of a cylinder is measured from the center to the side of the face, where as the diameter is measured from side to side through the middle, so the diameter will always be twice the radius of the same circle, meaning if the diameter is 10 units, then the radius will be half that, 5 units, then all we do is double the radius like the question says to get the height (NOTE this is NOT part of any formula for finding any dimensions for any shape and is specific to this question) then all we do to find the volume is use the formula below
V = (pi) (r^2) h
plug the radius or 'r' in as well as height or 'h' in the equation and solve

MovieMania, an online movie rental website charges a one-time fee of $6.85 and $2.99 Per movie rental. Let m represent the number of movies you watch and let C represent the total cost to watch the movies. write an equation that relates the total cost to the numbers of movies you watch from MovieMania
Answer:
C=6.85+2.99m, where:
C is the total cost to watch the movies
m is the number of movies you watch
Step-by-step explanation:
From the information provided, you can say that the total cost to watch the movies would be equal to the one-time fee plus the result of multiplying the price per movie for the number of movies you watch, which can be expressed as:
C=6.85+2.99m, where:
C is the total cost to watch the movies
m is the number of movies you watch
