Answer:
{x,y}={31,4}
Step-by-step explanation:
x-8y = -1 x-6y = 7
Answer:
first we find the value of 'y' so
x-8y=-10+8y
x=-10+8y
-2(-10+8y)-6y=-24
20-16y-6y=-24
20-22y=-24-20
-22y=-44
y=2
then also we can find the value of 'x'
-2x-6y=-24
2x-6(2)=-24
2x-12= -24
2x= -24+12
x= -12

How many integers between 2020 and 2400 have four distinct digits arranged in increasing
order? (For example 2957 is one such integer)
(B) 10
(C) 15
(D) 21
e 28
Answer:
the answer is E
Step-by-step explanation:
We want to find how many integers are between 2020 and 2400 such that a criteria is meet, and the criteria is that the four digits are different and are arranged in increasing order.
We will see that there are 15 of these numbers between 2020 and 2400, so the correct option is C.
---------------------------
To count the number of digits that meet the given criteria, we first need to analyze how the criteria is.
If the numbers must be in increasing order, then the smallest number that can be in the hundreds place is 3 (the smaller integer larger than 2).
so we have:
23__
The number next to the 3 can be a 4, for example:
234_
And the final number can be any number larger than 4, so we have {5, 6, 7, 8, 9} a total of 5 options.
If instead of a 4, the number next to the 3 is a 5, we have:
235_
And the number next to the five can be any digit larger than 5, so now we have 4 options.
If instead of a 5, we have a 6, we will have 3 options to put after the 6.if instead of a 6, we have a 7, we will have 2 optionsif instead of a 7, we have an 8, we will have 1 option.Now, we can't have another number than a 3 in the hundreds place, because if we put a 4 there, we are out of the range, and 3 is the smallest digit that we can use there.
Then we already saw all the possible numbers that we can make, adding the numbers of options that we got above we will get:
5 + 4 + 3 + 2 + 1 = 15
This means that are 15 of these numbers between 2020 and 2400. Then the correct option is C.

Step-by-step explanation:
if y varies directly with x and x increases by 2 , is it possible to determine by how much y increases or decreases . yes or no and why
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
y ∝ x
y = kx
Where k is a constant and it can be any integer.
If y varies directly with x.
Yes, it is possible to determine by how much y increases or decreases as x increases.
If x increases by 2 then y also increases by 2.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
y varies directly with x.
This can be written as an equation,
y ∝ x
y = kx
Where k is a constant and it can be any integer.
Now,
If x increases by 2.
y = 2k
If k = positive integer
Then y will increase by 2k.
If k = negative integer
Then y will decrease by -2k
So,
Yes, it is possible to determine by how much y increases or decreases.
Thus,
If y varies directly with x.
Yes, it is possible to determine by how much y increases or decreases as x increases.

Answer:
6x9=54 11x8=88
Step-by-step explanation:
i dont get it hope it helps
Answer: x= -10
Step-by-step explanation:
Let's solve your equation step-by-step.
6x−9=8x+11
Step 1: Subtract 8x from both sides.
6x−9−8x=8x+11−8x
−2x−9=11
Step 2: Add 9 to both sides.
−2x−9+9=11+9
−2x=20
Step 3: Divide both sides by -2.
−2x /-2= 20/-2
x=−10
Answer:
x=−10

Write an equation in slope-intercept form of the line with slope 3/4 that contains the point (-4,1)
Answer:
y = 3/4x + 4
Step-by-step explanation:
to put it into slope intercept form, you need to find the y intercept or b becasue the slope intercept form is y = mx + b where b is the y intercetpt and m is the slope. To find b you insert the points you were given so 1 = -4(3/4) + b
which simplifies to 4 = b so then you can put in your slope and y intercept into slope intercept form

problem #5
9514 1404 393
Answer:
y = 26
Step-by-step explanation:
You have already correctly solved for x, so you know that ...
m∠8 = 4(17)+10 = 78
Angle 12 is an alternate interior angle with respect to angle 8, so is congruent to angle 8.
m∠12 = m∠8
3y = 78
y = 78/3 . . . . divide by the coefficient of y
y = 26
If the point of the preimage is (5,2) and the point of the image is (1,2), what RULE was applied to the preimage to obtain the image?
A) (x, y + 4)
B) (x + 4, y)
C) (x - 4, y)
D) (x, y - 4)
Explanation:
We have x = 5 turn into x = 1. We need to subtract 4 from the x coordinate to get this. Therefore x turns into x-4.
The y coordinate stays at y = 2 the entire time, so y isn't altered. We have y map to y.
Overall, the rule is [tex](x,y) \to (x-4, y)[/tex] which translates the point 4 units to the left.
