Step-by-step explanation:
y-7=4(x-2)
we need to simplify the y to het a
y-7=4x-8 (i did 4x-8 because of 4(x-2)
now y= 4x-8+(-7)
after calculating -8+(-7) IT becomes
y=4x-15
okay we have the guide Line
y=4x-15
the a is 4
because
a = {y=a.x+b}
now we need to find the points using this guide Line
y=4x-15
x= 2(you can add any number here ,we Just need to know where the point is )
y= 4(2)-15
y=8-15
y= -7
points are (2,7)
Answer:
2
Step-by-step explanation:
There are four giraffes that equal 32. That means the four of them equal 32, and since they are all giraffes, they are the same amount.
32/4 = 8
Girrafe = 8
Two tigers times a giraffe equals 32. We already know that a girrafe equals 8.
32/8 = 4.
Therefore the two tigers equal 4. Since there are two tigers, and they equal 4, each tiger equals 2.
Now we know girrafes equal 8, and tigers equal 2.
A girrafe - A tiger x 3 = 2
PEMDAS says that you multiply first. So 2 x 3 equals 6. Take away 6 from 8 and you get 2.
Answer:
10
Step-by-step explanation:
The number of tiles in the design is 1 + 2 + 3 + ...
We can model this as an arithmetic series, where the first term is 1 and the common difference is 1. The sum of the first n terms of an arithmetic series is:
S = n/2 (2a₁ + d (n − 1))
Given that a₁ = 1 and d = 1:
S = n/2 (2(1) + n − 1)
S = n/2 (n + 1)
Since S ≤ 60:
n/2 (n + 1) ≤ 60
n (n + 1) ≤ 120
n must be an integer, so from trial and error:
n ≤ 10
Mr. Tong should use 10 tiles in the final row to use the most tiles possible.
Answer: -4
The formula for slope is rise/run. This means that between two points, you have to see the distance going up and down/ left and right.
Looking at points (0,-1) and (3,-1), you can see that the height difference is 4 units. This means that the rise is 4.
rise/run
4/run
Left and right, the difference is only one unit.
4/run
4/1
4
This graph is also negative, so let’s add that in.
-4
This is your answer! I know it wasn’t one of the options you provided, but I’m pretty sure that this is the answer.
