2016年3月25日 · x~~2.07 1. Since the left and right sides of the equation do not have the same base, start by taking the logarithm of both sides. 5^x=28 log(5^x)=log(28) 2.

Question: 31. Describe the function y - -28(x)+ 5 as a transformation of the function y g(x). A) Stretch horizontally, reflect across x-axis, shift left 5 (B) Compress vertically, reflect across x-axis, shift up 5 (C) Stretch vertically, reflect across x-axis, shift up 5 (D) Compress vertically, reflect across y-axis, shift up 5 (E) Stretch horizontally, reflect

x=23 >"to isolate x subtract 5 from both sides of the equation" xcancel(+5)cancel(-5)=28-5 rArrx=23" is the solution"

We just multiply the numerators (35 and x) by 4 and 28 respectively, and then we divide by 28. It looks like this: 35*4=28*x (35*4)/28=x 140/28=x 5=x It just means skipping steps, but as long as you know what steps you're brushing over, you should be fine.

The given trinomial is 15 x 2 − 28 x + 5. This is a quadratic expression of the form a x 2 + b x + c.

Question: Divide. (5x^(2)-31x+28)-:(x-5) Your answer should give the quotient and the remainder.

Evaluate the algebraic expression for the given value of the variable. x2-28; x= -5 For x = -5, x2 - 28 = 0 (Type an integer or a simplified fraction.) 11 Your solution’s ready to go! Our expert help has broken down your problem into an easy-to-learn solution you can count on.

2018年5月17日 · (x-5)/(4(x-7)), with the restriction x != 7. The numerator (x-5) can not be made simpler by factoring, but the denominator can. In 4x-28, both 4x and –28 are multiples of 4.

Example 1: Factor the Denominators x + 5 5 Solve for x: 28 *** x x + 2 x2 4. - Solution: Step 1: Factor all denominators. Submit the entire equation with all denominators factored below.

1. Solar Slab Storage. A passive solar home has a concrete slab in its main living area, 22' x 28' x 5" thick. On a winter day, the average slab temperature is 64.2F in the morning, and 73.4F in the afternoon when the sun sets. How much heat was absorbed by the slab (in kBtu)? 2. Gas Use.
