Answer:
(100,113) is on the graph of y = 1.2x -7
Step-by-step explanation:
y=1.2x−7
Substitute the point in and see if the equation is true
113 = 1.2 (100) -7
113 =120 - 7
113 = 113
This is true, so the point is on the graph
What number is shown by the model?
A. 28
B. 2080
C. 208
o
D. 280
Answer:
280
Step-by-step explanation:
each of those squares are 100 and each bar is 10
add up the squares and you have 200
add up the bars and you have 80
add 200 and 80 and you have your answer. 280
Answer:
D
Step-by-step explanation:
Well, the bars, if you count them are ten for each column.
There are 8 bars on the right, so that is 280 - 80 = 200
There are two squares that are ten by ten, so that is 200 - 100 * 2 = 0

Answer:
wrong its actually D. x=7, y=1
i just took the test
The solution of the equation is x=7 and y=1, option D is correct
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equations are 3x - 5y = 16 and 2x - 7y= 7
we have to solve the equations
6x-10y=32...(1)
6x-21y=21...(2)
6x-10y-6x+21y=32-21
11y=11
Divide both sides by 11
y=1
Now plug in y value in any of equation to get x

The product of two rational numbers is ______ rational.
The product of two rational numbers is always rational
Proof:
Let a = p/q and b = r/s be two rational numbers. We will have p,q,r,s be integers where denominators q and s are nonzero. We cannot divide by zero.
Multiplying a and b gives
a*b = (p/q)*(r/s) = (p*r)/(q*s)
Due to the closure property of integer multiplication, the expressions p*r and q*s are integers. The result we get is in the form of integer/integer. Basically we have two integers being divided. Furthermore, q*s is nonzero as neither q nor s is zero.
Therefore, if a and b are rational, then a*b is also rational as well.
If the probability of turning left is 0.5 and the probability of
turning right is 0.5 for each mouse, what is the probability that ONLY ONE
of the two mice will turn left? *
Answer:
0.5
Step-by-step explanation:
The probability that the first mouse turns left and the second mouse turns right is 0.5 × 0.5 = 0.25.
The probability that the first mouse turns right and the second mouse turns left is 0.5 × 0.5 = 0.25.
So the probability that only one mouse turns left is:
P = 0.25 + 0.25
P = 0.5
Another way of looking at it: the probability that only one mouse turns left is 1 minus the probability that both turn left or both turn right.
P = 1 − (P(both left) + P(both right))
P = 1 − (0.5 × 0.5 + 0.5 × 0.5)
P = 0.5

A bowl contains a total of 26 blue and red marbles. There are two more red marbles than
blue marbles. How many blue marbles are in the bowl?
Which of the following let statements should you use?
Let x = the number of red marbles. Let x + 2 = the number
of blue marbles.
Let x = the number of blue marbles. Let 2x = the number of
red marbles.
Let x = the number of blue marbles. Let x + 2 = the number
of red marbles.
Answer:
There are 26 total marbles. We will call x the number of blue
marbles. So there are x+2 red marbles. If you add them together you
get x + x + 2....and all that equals 26 (subtract 2 from each side

Which shows all the critical points for the inequality ? , x = 1, and x = 2 x = –6 and x = 2 x = –4 and x = 2 x = 2
Answer:
The variable is the main part, it is the base of the whole thing
The variable is the main part, it is the base of the whole thing that shows all the critical points for the inequality ? , x = 1, and x = 2 x = –6 and x = 2 x = –4 and x = 2 x = 2.
How do you find the critical points of an inequality?Solve a rational inequality.
Determine the critical points–the points where the rational expression will be zero or undefined. Use the critical points to divide the number line into intervals. Test a value in each interval. Above the number, the line shows the sign of each factor of the rational expression in each interval.
How do you find the critical points of a function?To find the critical points of a function y = f(x), just find x-values where the derivative f'(x) = 0 and also the x-values where f'(x) is not defined. These would give the x-values of the critical points and substituting each of them in y = f(x) will give the y-values of the critical points.

-7+ 5Y = -37 simplify your answer as much as possible
Answer:
y = -6
Step-by-step explanation:
To simplify this equation as much as possible, we have to get the variable y by itself.
To do this, we would do the inverse operation of subtraction and add 7 to the left and right side of the equation.
-7 + 7 + 5y = -37 + 7
The 7s cancel out on the left side because -7+7 = 0 and so we are left with,
5y = -30
Then we would do the inverse operation of multiplication and divide by 5 on the left and right side of the equation.
5y/5 = -30/5

Answer: No, it is not
Step-by-step explanation:
AREA DEFINITION: Area is 2-dimensional: it has a length and a width. Area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle, multiply the length by the width.
SURFACE AREA DEFINITION: The surface area is the sum of the areas of all six sides. To find the area of adjacent sides (Width x Height) x 2 sides. Find the area of ends (Length x Width) x 2 ends. Add the three areas together to find the surface area.
Without drawing the graph of the function y=1.2x−7, see if the graph passes through points: (100; 113)
Answer:
The graph of the function passes through the point (100; 113).
Step-by-step explanation:
In order to calculate if the graph of the function passes through the point or not, we need to insert the point's coordinates in the function and check if the equation is valid or not, if it is, then the graph passes through them.
[tex]y(x) = 1.2*x - 7\\y(100) = 1.2*100 - 7\\y(100) = 120 - 7 \\y(100) = 113[/tex]
Which is equal to the "y" coordinate of the point, therefore the graph of the function passes through the point (100;113).
