logarithms question (answer)
Use the addition property: Logx(yz)=logx(y)+logx(z). Thus, Logx(yz)=.7+.6
Use the addition property: Logx(yz)=logx(y)+logx(z). Thus, Logx(yz)=.7+.6
Two graphs intersect where their equations are equal. Thus, the graph f(x) intersects with the graph g(x) where f(x)=g(x). Upon setting the equations equal to each other, solve for x. With the x-value, you can then substitute it back into either function to solve for the y-value...
The equation of a line is given by y=mx+b where m is the slope and b is the y-intercept. First, to solve for the slope, use "rise over run," or "y over x:" m=(y2-y1)/(x2-x1) where (-13, 13) is the first point and (20, -53) is the second point. Thus,...
The perimeter is basically the outline of the shape. The perimeter of a rectangle is given by P=2l+2w, where l is the length and w is the width. Thus, the perimeter of the flower bed would be given by P=2(3n5o)+2(5n5o). In this instance, you could distribute to get 6n10o+10n10o...
The distributive property basically means that you are going to multiply everything on the outside of the parenthesis bit everything on the inside of the parenthesis. For example: in 2(4+x), you need to multiply 2 by 4 and 2 by x to get 8+2x This is true also for variables:...
If the equation is (7/3)x=63, then you would need to multiply both sides of the equation by the reciprocal of the fraction (3/7). If the equation is 7/(3x) = 63, where the x is on the bottom of the fraction, then you need to cross multiply to get the x on the top. Afterwards,...
Actually, you need to add fifteen to both sides of the equation in order to remove it from that side of the equal sign. (Basically, you are doing -15+15=0 on the right side and 0+15=15 on the left.)
First, you need to get y by itself on one side of the equal sign. To do that, start with any numbers without a variable: add six to both sides. Then move the x to the other side: subtract x from both sides. To separate y from the -4, divide both sides by -4 (remember...
"More than" indicates addition, so we know that we are adding twelve to "a number," which we will call x. "Product" indicates multiplication, so you know you're multiplying by four. The placement of "and" tells us that we are multiplying four by...
Use the order of operations: Please Excuse My Dear Aunt Sally, or Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.
Typically, a thesis statement is a single sentence at the end of your introductory paragraph and states the argument you plan to explain further in your essay. A title is much shorter, usually a few words, and should hint at your essay's topic and your thesis. For example,...
