Alexis recieved an 85,89,92on three tests.How many points does she need to score on her next test in order to have an average of
Vladimir [108]
94

(85+89+92+x)/4 = 90

(266+x)/4 = 90
(Multiply by 4 on each side to get rid of it)

266+x=360
(subtract 266 from each side)

x = 94

Find the equation of line (use exact numbers)​
maw [93]

Answer:

y=3x+3

Step-by-step explanation:

Use the slope-intercept form:

y=mx+b

m is the slope and b is the y-intercept. The y-intercept is the place where x is equal to 0, and the slope is the change in the y-axis over the change in the x-axis, otherwise known as rise over run ( \frac{rise}{run} ).

If you study the graph, you can see that the line crosses the y-axis at (0,3), so 3 is the y-intercept. Insert into the formula:

y=mx+3

Now find the slope. Use the slope formula:

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{rise}{run}

You need two points first. You can use the y-intercept (0,3) and another even point, like (1,6). Insert the values:

(0_{x1},3_{y1})\\(1_{x2},6_{y2})\\\\\frac{6-3}{1-0}=\frac{3}{1}=3

The slope is 3. Insert this value:

y=3x+3

Now, solve this problem. 106% of $ _______ = $7.95 
Alex787 [66]

Answer:

7.5

Step-by-step explanation:

106% of $x = $7.95

In other words,

\[\frac{106}{100}\] of $x = 7.95

Multiplying both sides of the equation by \[\frac{100}{106}\]

\[\frac{106}{100} * \frac{100}{106}\] of x = 7.95 * [\frac{100}{106}]

=> x = [\frac{750}{100}]

=> x = [\frac{7.50}{1}]

=> x = 7.5

Validation: 106% of 7.5 = 7.95
