The answer is 42= 7(9-3), z would be 9
Answer:
-6/5 x 5/3 x 11
Step-by-step explanation:
the commutative property states that x * y = y * x where "x" is a number and "y" is also a number and also x+y=y+x. also "*" is the multiplication symbol
-6/5*11*5/3 can be re-arranged into 11*-6/5*5/3 you can cancel the numbers to get 11*-2/3*5=55*-2/3=-110/3
Answer:
A
Step-by-step explanation:
For point-slope form, you need a point and the slope.
y - y₁ = m(x - x₁)
Looking at the graph, the points you have are (4, 0) and (-4, -4). You can use these points to find the slope. Divide the difference of the y's by the difference of the x's/
-4 - 0 = -4
-4 - 4 = -8
-4/-8 = 1/2
The slope is 1/2. This cancels out choices C and D.
With the point (-4, -4), A is the answer.
The equation of a straight line is y=mx+b, where m is the slope and b is the y intercept. Substitute your value for the slope to give you y=1/4x+b. Now substitute the complete coordinate into this equation and solve for b:
-3=(1/4×7)+b
-3=1.75+b
b=-4.75
So now you have the full equation, y=1/4x-4.75
Now substitute the incomplete coordinate so you can find h:
-1=(1/4×h)-4.75
3.75=1/4h
÷1/4 (which is 0.25 as a decimal)
h=15
