Answer: No, y=7/9x+6 is not proportional. The line does not pass through the origin, (0,0).
Lets take a look at the options first.
option 1 and option 4 are not possible as (8x) (8x) would give us 64x^2, which is not what we want.
we’re left with option 2 & 3. when expanded, option 2 will look like :
16x^2 - 40x - 10x + 25
= 16x^2 - 50x + 25
however, we do not want the 50x. so the answer is option 3, (4x-5) (4x+5)
if you don’t want to find the answer using expanding, there is also another method of expanding.
(a+b)^2 = a^2 - b^2
in this case, 16x^2 will be a^2 and 25 will be b^2. not sure whether you’ve learn this but yea.
Answer:
y = 3/4x - 2 2/3
Step-by-step explanation:
Are there choices?
y = 3/4x + b
1/3 = 3/4(4) + b
1/3 = 3 + b, b = -2 2/3
y = 3/4x - 2 2/3
Answer:
At first find the lowest common multiple of 3, 4, 10
so it is 60
and 60is a factor of 120 and also the sum of the digits of 60 = 6+0 = 6
.°. 60 is the answer
