The ordered pair (3, 2) is the solution of which system
of equations?
Answer:
A solution to a linear system, or simultaneous solution, is an ordered pair (x, y) that solves both of the equations. In this case, (3, 2) is the only solution.
Step-by-step explanation:
What is the constant rate of change for the relationship shown in the table?
Answer:
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The rate of change is the change in y over the change in x. In this table, the change in y is +1, and the change in x is +3, so we get [tex]\frac{1}{3}[/tex]
PLEASE HELP ! Pleaseeee
Answer:
short leg: 4
hypotenuse: 8
this is a 30,60,90 triangle.
angle against the 90 degrees is the hypotenuse. Against the 60 degrees is the long leg and against the 30 degrees is the short leg. So since we know the long leg we can find the short leg. The short leg is the long leg/ square root(3) so the short leg is 4.
Now to find the hypotenuse youdo 4^2 + 4 square root(3)^2 which is 64 squared. Or 8

Step-by-step explanation:
the function g is defined as follows for the domain given. g(x)=2x-2, domain=(-3,-2,1,5). find the range of g using set notation.
Answer:
[tex]Range: \{y|y = -8,-6,0,8\}[/tex]
Step-by-step explanation:
Given
[tex]g(x) = 2x - 2[/tex]
[tex]x = \{x|-3,-2,1,5\}[/tex]
Required
The range using set notation
We have:
[tex]g(x) = 2x - 2[/tex]
When [tex]x = -3[/tex]
[tex]g(-3) = 2*-3 - 2 = -8[/tex]
When [tex]x = -2[/tex]
[tex]g(-2) = 2*-2 - 2 = -6[/tex]
When [tex]x = 1[/tex]
[tex]g(1) = 2*1 - 2 =0[/tex]
When [tex]x=5[/tex]
[tex]g(5) = 2*5 - 2 =8[/tex]
So, we have:
[tex]y = -8,-6,0,8[/tex]
Using set notation, the range is:
[tex]Range: \{y|y = -8,-6,0,8\}[/tex]

Where did 35 come from?
35 is the sum of the first five triangular numbers, making it a tetrahedral number. 35 is the number of ways that three things can be selected from a set of seven unique things also known as the "combination of seven things taken three at a time". ... 35 is the highest number one can count to on one's fingers using base 6.
last year Patrick paid £2534 for his annual train ticket this year he has to pay £2612 for his annual train ticket. work out the percentage increase in the cost of his train ticket. give your answer correct to 3 significant figures.
Answer:
Percentage increase in the cost of his train ticket = 3% (Approx.)
Step-by-step explanation:
Given:
Cost of annual ticket paid by Patrick last year = £2,534
Cost of annual ticket paid by Patrick current year = £2,612
Find:
Percentage increase in the cost of his train ticket
Computation:
Percentage increase = [(Current - Base) / Base]100
Percentage increase in the cost of his train ticket = [(2,612 - 2,534) / 2,534]100
Percentage increase in the cost of his train ticket = [(78) / 2,534]100
Percentage increase in the cost of his train ticket = [0.03078]100
Percentage increase in the cost of his train ticket = 3.078
Percentage increase in the cost of his train ticket = 3% (Approx.)
Which number is closest to 1
A. 0.987
b. 0.111
c.0.561
d. 0.786
Answer:
Letter A
Step-by-step explanation:
Just think: which number would have the greatest value if it was rounded to the nearest hundredth
Answer: A
Step-by-step explanation:
I think the answer is correct becuase, If we taken all the numbers and put them on a number line they would all be under one. But when we look at the number line we would see that .987 is the closest because it is almost a whole number. And even if we did it without the number line what ever number we see that has the greatest digit and its in the negatives thats the closest to one. (I hope what I said makes sense!)

(-2, 11) & (5,6)
What is the slope of the equation between these two points?
Answer:
[tex] m =\dfrac{-5}{7}[/tex]
Step-by-step explanation:
Given :-
Two points (-2,11) and (5,6) .And we need to find out the slope of the equation between the two points. The slope of the line passing through two points , is given by ,
[tex]\implies Slope (m) =\dfrac{ y_2-y_1}{x_2-x_1}[/tex]
Here the two points are (-2,11) and (5,6) .So put on the respective values ,[tex]\implies Slope (m) =\dfrac{ 11 - 6}{-2-5}\\\\\implies Slope = \dfrac{5}{-7} \\\\\implies Slope = \dfrac{-5}{7} [/tex]
Hence the slope of the line is -5/7 .

Answer:
(x, y) = (-2, 7)
Step-by-step explanation:
Add the first equation to twice the second.
(4x +4y) +2(2x -2y) = (20) +2(-18)
8x = -16 . . . . . . simplify
x = -2 . . . . . . . . divide by 8
__
2(-2) -2y = -18 . . . . .substitute into the second equation
y + 2 = 9 . . . . . . . . . divide by -2
y = 7 . . . . . . . . . . . subtract 2
The solution is (x, y) = (-2, 7).

How do we get 45 in this????
Answer:
A. 45h = 1,575
Step-by-step explanation:
Area of trapezoid = 1,575 cm² (given)
We are given the length of both bases, a = 63 cm and b = 27 cm
We need to find the formula that will enable us determine its height (h).
Thus:
Area of trapezoid = ½(a + b)h
Plug in the values
½(63 + 27)h = 1,575
½(90)h = 1,575
45h = 1,575
The answer is A. 45h = 1,575
Solve for xxx in the diagram below.
need help with this
(A) delta h(t) = 32
Step-by-step explanation:
Average rate of change delta h(t) is given by
[tex]delta \: h(t) = \frac{h(b) - h(a)}{b - a} [/tex]
at t = 0, h(0) = 80
at t = 2, h(2) = -16(4) + 64(2) + 80 = 144
Plugging in the numbers
delta h(t) = (144 - 80)/(2 - 0)
= 32
Find the indicated variable in the trapezoid below.
NEED TO FIND x,y, and z
9514 1404 393
Answer:
x = 40y = 68z = 128Step-by-step explanation:
The midsegment (x) has a length that is the average of the base lengths:
x = (48 +32)/2 = 80/2
x = 40
__
The end angles are supplementary:
y° = 180° -112° = 68°
y = 68
__
z° = 180° -52° = 128°
z = 128

How do to solve 7x-1 over 22 = 3x+1 over 10
Answer:
7x-1/22 = 3x+1/10
Multiply both sides of the equation by the Lowest common Multiple of the denominators(22 and 10). This is done to clear the fractions.
The LCM of 22 and 10 is 110
So
110 x(7x-1/22) = 110 x (3x+1/10)
110/22 =5
110/10 = 11
So the eqn now becomes
5(7x-1) = 11(3x+1)
Opening the parentheses
35x - 5 = 33x + 11
Collect Like Terms
35x - 33x = 11 + 5
2x = 16
x= 8.

Step-by-step explanation:
What type of triangle, if any, can be formed with angle measures of 32, 126, and 32°?
A. no triangle
B. either an acute isosceles triangle or an obtuse isosceles triangle
C. only an obtuse isosceles triangle
D. only an acute isosceles triangle
Answer:
C. only an obtuse isosceles triangle
Step-by-step explanation:
the triangle has two congruent(equal) angles that are both 32°, and a triangle with two congruent angles is an isosceles triangle.
the third angle, 126°, in the triangle is an obtuse angle because it is larger than 90°, and a triangle with one obtuse angle is an obtuse triangle
thus, the triangle with angle measures of 32, 126, and 32° is both an isosceles and obtuse triangle.
