Answer:
Step-by-step explanation
Substitute 2y-1 for x in the second equation:
7x + 5y = -66
7(2y-4) + 5y = -66
then solve for y:
14y - 28 + 5y = -66
19y = -38
y = -2
Substitute -2 for y in the first equation:
x = 2y - 4
x = 2(-2) - 4
x = -8
The lines intersect at (-8,-2)
Find measure of angle PQS
Answer:
ANGLE PQS = 45°Step-by-step explanation:
angle SRT = 180 - 70 = 110
thus angle QSR = 180 - 20 - 110 = 50
BY Angle sum property
angle PQS = 180 - 85 - 50 = 180 - 135 = 45
Answer:
<PTR+<RTS=180 LINEAR PAIR
<PTR=180-20=160°
Step-by-step explanation:
IN QUADRILATERAL PQRT
<P+<Q+<R+<T=360 SUM OF INTERIOR ANGLE OF QUADRILATERAL IS 360
85+<Q+70+160=360
<Q=360-315=45°
angle PQS=45°
1/6=n+7/9 what does n equal
Answer:
n=-11/18
Step-by-step explanation:
1/6=n+7/9
Change the sign and move the variable to the left hand side
-n+1/6=7/9
Change its sign and move constant to the right hand side
-n=7/9-1/6
Subtract the fractions
-n=11/18
Change the sign on both sides
n=-11/18
how can you determine if the association on scatter plot is strong or weak
Answer:
We say that a strong negative association exists between the variables x and y. Consider the following scatterplot: We observe that y increases as x increases, and the points do not lie on a straight line. We say that a weak positive association exists between the variables x and y.
Step-by-step explanation:
Answer:
We say that a strong negative association exists between the variables x and y. Consider the following scatterplot: We observe that y increases as x increases, and the points do not lie on a straight line.

Alyson earned $40 in commission from her sales. How much did she sell if her commission rate is 15%?
Answer:
$266.67 (Verified) ✅Step-by-step explanation:
Let the merchandise she sold = x
Her commission is 15% of that, so 15% of x or 0.15x
We know her commission was $40, so 0.15x = $40
0.15x = $40
Divide by 0.15
x = $266.67
We can check our answer by substituting $266.67 back into the equation.
0.15(266.67) = 40
40 = 40 ✅
Alyson sold $266.67 worth of merchandise.

Alyssa, Bradley, Carl, and Dionne each made a statement about the relation {(1,2), (3,4), (5,6),100,101)). Which student's statement is completely true?
А.
Alyssa said "It is not a function because there are not enough values in the domain."
B
Bradley said "It is a function: y = + 1 for all in the domain."
C С
Carl said it is not a function because the values in the domain are not interchangeable with those in the range."
Dionne said "It is a function: y = x + 1 for all in the domain."
D.
Answer:
Dionne is correct
Step-by-step explanation:
x=1 y=x+1 for example: if x=33 y would = 34
The correct statement is " It is a function: y = x + 1 for all in the domain."
Option D is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
(1, 2), (3, 4), (5, 6), (100, 101)
We can make a function.
y = mx + c
Now,
Take two ordered pairs.
(1, 2) and (3, 4).
And,
m = (4 - 2) / (3 - 1)
m = 2/1
m = 1
Now,
(1, 2) = (x, y)
2 = 1 x 1 + c
2 - 1 = c
c = 1
Now,
y = x + 1
So,
The relation is a function and the function is y = x + 1.

Given:
Radius of circle = 3 units
Angle between radius = 60°
Find:
Length of arc CE
Computation:
Length of arc = [θ/360][2πr]
