Slope intercept form is y = mx + b.....so lets solve for y
9x - 7y = -7 .....subtract 9x from both sides
-7y = -9x - 7...now we divide both sides by -7
y = 9/7x + 1 <==
the answer is one :))))))))))))))))))))
Answer:
y = 3
Step-by-step explanation:
9 - y = 2y
+ y + y Add y to both sides
9 = 3y Divide both sides by 3
3 = y When y = 3, the value of 9 - y is twice the value of y.
15 is the half of 30 keep counting so when you get to 50 the number you have is the answer
Answer:
64 times more paint will be needed since the volume of the second is 64 times the volume of the first
Step-by-step explanation:
If the original sphere is 12 cm diameter
its radius will be half this measure which is 12/2 = 6 cm
The new diameter is 4 times this, so its radius would be 4 times this and it is 24 cm
Now, the volume of the sphere means we have to raise the power of the radius by 3
The other terms in the formula remains the same for both, so we are simply comparing the radii
so we will have the difference in volume in times of multiples as ;
(24/6)^3 = 4 * 4 * 4 = 64
