I disagree, the equation is in y=mx+b form. The slope, or m, is 0, so the equation is y=0x+7. That simplifies to y=7.
Plz mark me brainliest!
Hope this helps!
The answer is the first one, (2)
Estimation is a process by which we do not exactly do the operation but predicts through pre-known facts and methods in order to determine the required. In this item, we are to predict or estimate the place of the decimal point to the answer when we divide the 42.56, dividend, and 22, our divisor.
We can say that 42 can be divided by 22 only once because twice of 22 is already 44. By this we can say that the decimal place will be after 1. There would only be one digit to the left side of the decimal point.
If we are going to answer the division problem, we get an answer of 1.934545..
Answer:
Step-by-step explanation:
let width=w
length=l
l=3w
P=2(l+w)=2(3w+w)=8w
A=l*w=3w*w=3w²
3w²=8w+128
3w²-8w-128=0
3w²-24w+16w-128=0
3w(w-8)+16(w-8)=0
(w-8)(3w+16)=0
w=8,-16/3 (rejected)
width=8
length=8*3=24
Answer:
Infinite amount of solutions
Step-by-step explanation:
Step 1: Write equation
5(x + 2) = 5x + 10
Step 2: Solve for <em>x</em>
- Distribute 5x + 10 = 5x + 10
- Subtract 10 on both sides: 5x = 5x
- Divide both sides by 5: x = x
We see here that <em>x</em> is infinite amount of solutions. We can plug in any value <em>x</em> and it would render the equation true.
