Right this is pretty simple all you do is sub the points to the equation given.
So first try the first point (2,-1) in y=-3x+7
==> -1=-3(2)+7
==>-1=1 this is not equal therefore not the right points
Then try (1,10)
==>10=-3(1)+7
==>10=4 this is incorrect therefore not the right points
Next try (3,-2)
==>-2=-3(3)+7
==>-2=-2 this is equal therefore this is the coordinates to the linear equation.
Finally try the last points to make sure you are correct.
==> -8=-3(-5)+7
==>-8=22 this is incorrect also.
Therefore the only coordinates that satisfies the equation is (3,-2)
Answer:
First blank- 32000 ounces
Second blank- 2000 pounds
Yes the bridge can hold 1 ton.
Step-by-step explanation:
The ratio of the scale of the model to the real bridge = 1:4
The test model shows the model can take 8000 ounces
The real bridge will therefore take 8000 x 4 = 32000 ounces
16 ounces = 1 pound
32000 ounces = x pounds
==> = 32000/16 = 2000 pounds
2000 pounds = 1 ton
therefore the bridge holds 1 ton
Answer:
The picture shows the answer on the graph
Step-by-step explanation:
-2=-3/4×(x-6)
Distribute -3/4 through the parenthesis
-2= -3/4x+9/2
Multiply both sides of the equation by 4
-8=-3x+18
Move the variable to the left side and change its sign
3x-8=18
Move constant to the right side and change its sign
3x=18+8
Add the numbers
3x=26
Divide both sides of the equation by 3
x=26/3
Alternative Form- x=8 2/3 or x=8.6
The simplest way to do this is to set up equivalent fractions. So, you'd do:
=
and then solve for x.
x=52
