Answer:
y=6,5,4,3 are value for y
9514 1404 393
Answer:
0.4, 0.004, 0.004
Step-by-step explanation:
The "what" in each case is found by dividing the target value by 10. That is accomplished by moving the decimal point one place to the left.
4/10 = 0.4 ⇒ 10 times 0.4 = 4
0.04 and .04 are exactly the same value, so the last two on your list are the same:
0.04/10 = 0.004 ⇒ 10 times .004 = 0.04
Answer:
y = -2x - 7
Step-by-step explanation:
x - 2y = 6
-2y = -x + 6
Divide the whole equation by (-2)
slope = 1/2
Slope of the line perpendicular to this line = -1/m = -1 ÷ (1/2)
(-3, - 1)
y -y1 = m(x -x1)
y - [-1] = -2(x - [-3])
y + 1 = -2(x + 3)
y + 1= x* (-2) + 3*(-2)
y + 1 = -2x - 6
y = -2x - 6 - 1
y = -2x - 7
Answer:
x=5
Step-by-step explanation:
First you have to solve for y. Since it is a isoceles triangle, the two base angles are equal. You dont even need to solve for y because both of them will equal 73. Now you know two of the angles are 73 degrees, 146 in total. Since you know the total degrees in a triangle is 180, set up an equation that is adding all the angles to equal 180. Then solve for x.
Solve:
73+73+(6x+4)=180
146+6x+4=180
150+6x=180
6x=30
x=5
Answer:
The lowest point is -100 meters, or 100 meters down
Step-by-step explanation:
D(x)=1/36(x-60)^2-100
This equation is in vertex form
y = a(x-h)^2 +k where (h,k) is the vertex
Since a is positive, the parabola opens up
The vertex is the minimum, which means it will be the lowest point
The vertex is (60,-100)
The lowest point is -100 meters, or 100 meters down
