SOMEONE PLEASE HELP ME ;( Your teacher asked your class to describe a real-world situation in which a y-intercept is 100 and the slope is 5. Your partner gave thefollowing description: My younger brother originally had 100 small building blocks, but he has lost 5 of them every month since. What mistake did your partner make? Describe a real-world situation that does match the situation.

Answers

Okay so your partner describes a situation that has a slope of NEGATIVE 5, not positive 5 as your teacher asked.
Instead, your younger brother could have started with 100 and GAINED 5 every month, instead of losing 5.

Explain how to use the combine place values strategy to find 223-119

Answers

Combine place value strategy is useful if you try to subtract a number with bigger digits from a number with a smaller digit in the same place... such as now, where 3 is smaller than 9 in the ones place.

Then we can combine two place values: 23 and 19 and subtruct those. 23-19 is 4 (you can just count up from 19 to 23), so you know that the two will give the result of 04, and then you can proceed to the left: 2-1=1.

so the final result will 104.

Answer:

$(2)/((x-1)x(x+1))$ , $(y^4)/(8)$ , and $(2)/(3t)$

Step-by-step explanation:

Let's find a common denominator:

$(x(x+1))/((x-1)x(x+1)) - (2(x-1)(x+1))/(x(x-1)(x+1)) + ((x-1)x)/((x+1)(x-1)x)$

$(x(x+1) - 2(x-1)(x+1)+(x-1)x)/((x-1)x(x+1))$

= $(2)/((x-1)x(x+1))$

2/(x-1)x(x+1)

$((2y^2)^3)/((8y)^2)$

Distribute exponents:

2^3(y^2)^3

__________

8^2(y)^2

Numerator:

2 to the power of 3 equals (2 · 2 · 2) = 8

y to the power of 2 to the power of 3 equals, y to the power of 6 (this is because when exponents in parenthesis are held to the power of another number outside of the parenthesis, you multiply them)

Now let's simplify the denominator:

8 to the power of 2 equals (8 · 8) = 64

y to the power of 2 is just y to the power of 2, so our new expression is:

$(8y^6)/(64y^2)$

Let's cancel the terms further:

8/64 can be simplified to 1/8

And when you cancel exponents, you subtract the denominator's exponent from the numerator's exponent ( $y^(6-2)$ = $y^(4)$ )

Now put them together:

$(1(y^4))/(8)$

Which is,

= $(y^4)/(8)$

y^4/8

$(t+2)/(3t) - (1)/(3)$

The common denominator for both fractions is 3t, so let's make -1/3's denominator 3t by multiplying t to both the numerator and the denominator:

-1 · t

_____ = -1(t)/3t = -t/3t

3 · t

Now let's solve for the numerator:

$(t+2)/(3t) - (t)/(3t)$

(t + 2) - t, the t's cancel out, t - t + 2 = 2

And the denominator stays the same, so it will still equal 3t

Finally, you'll get an answer of

= $(2)/(3t)$

2/3^2

Solve for L: S=2WL+2LH+2WH

Answers

Answer:

Step-by-step explanation:

S = 2WL + 2LH + 2WH

S - 2WH = 2WL + 2LH

S - 2WH = L(2W + 2H)

(S - 2WH) / (2W + 2H) = L <===
