Answer and Step-by-step explanation:
Let's solve your equation step-by-step.
−2x−4=−4x+3
Step 1: Add 4x to both sides.
−2x−4+4x=−4x+3+4x
2x−4=3
Step 2: Add 4 to both sides.
2x−4+4=3+4
2x=7
Step 3: Divide both sides by 2.
2x/2 =7/2
So x is
7/2
(-8,-9)
Explanation:
y=2x+7 ; y=x-1
x-1=2x+7
x-1-7=2x+7-7
x-8=2x
x-x-8=2x-x
x=-8
y=x-1
y=-8-1
y=-9
Answer:
no. for it to be dilated it must be similar, thus the corresponding sides must be equal in ratio. however the bases 12 and 10. are not in equal ratios as the other sides which is half
37.68 Anything in the hundredths column that is five or higher, would raise the tenths column by one number. <span>37.7 In your example the 8 is higher than 5, so the 6 is raised to a 7 for rounding.</span>
Answer:
Number is two
Step-by-step explanation:
First of all we find the closest factors of 864 which are 32 x 27
Simply them we have
32 x 27 = 2^5 x 3³
So
Next we know that to be aperfect cube, each exponent needs to be equally divided by divisible by 3.
So If we multiply 864 x 2 we get
Then
1728 = 2^6 x 3³
So if we finally
Take the cube root of that is 2²* 3^1 = 4 x 3= 12
So 2² x 3^1
So if we equate the powers we have the answer as 2.
