Let:
x = Desired Number
The information put into numbers would look like this:
x - 5 = 3
All we have to do is add 5 to both sides to get x on its own on the left and a single number on the right side, so:
x = 3 + 5
x = 8

What is the slop-intercept of the line that passes through the points (7,-5) and (3,-9)?
bagirrra123 [75]

\bf (\stackrel{x_1}{7}~,~\stackrel{y_1}{-5})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{-9}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-9-(-5)}{3-7}\implies \cfrac{-9+5}{-4}\implies \cfrac{-4}{-4}\implies 1 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-5)=1(x-7) \\\\\\ y+5=x-7\implies y=x-12

Write an exponential function whose graph contains the points (1, 6) and (0, 2).
12345 [234]

Answer:

y = 2 (3)^{x}

Step-by-step explanation:

The exponential function is of the form

y = a (b)^{x}

To find a and b substitute the given points into the equation

Using (0, 2), then

2 = a (b)^{0} ⇒ a = 2

Using (1, 6), then

6 = 2 (b)^{1} ⇒ b = 3

Equation is y = 2 (3)^{x}

Shureka Washburn has scores of 89 , 65​, 68​, and 88 on her algebra tests. a. Use an inequality to find the scores she must make
PIT_PIT [208]
79. Set up an equation to solve this problem. Suppose she needs at least a score of x points. Her current total scores is 89+65+68+88=310. Her total score will be 310+2x (since final exams counts as two tests). The average score is total points divided by number of tests, and it has be bigger or equal to 78, so (310+2x)/6>=78. We solve it and get x=79. She has to score at least 79 on her final exam in order to jhave an overall average of 78.
