How do I solve this equation?
Keith_Richards [23]

Answer:

y=\frac{7}{2}x+11

Step-by-step explanation:

To solve, we need to find the y-intercept (b). In order to find the y-intercept, we can plug in the slope and the (x,y) coordinate pair given to us into the equation to solve for the y-intercept:

y=mx+b

4=(-7/-2)*-2+b

4=14/-2+b

4=-7+b

Add 7 to both sides

b=11

Therefore the equation is:

y=\frac{7}{2}x+11 (note that the fraction is positive since the two negatives cancel out)

Use the drop-down menus to complete the statements to match the information shown by the graph. A graph has weight (pounds) on t
NISA [10]

Answer:

Your drop down menus have the following choices:

First box: faster than, slower than, at the same rate as.

Second box: greatest x-value, line, y-intercept, slope.

Third box: greater than, less than, equal to.

Fourth box: greatest x-value, x-intercept, y-intercept, slope, origin.

Fifth box: minutes per gallon, gallons per minute.

Pool A is filling up slower than Pool B because the slope of the graph of Pool A is less than that of the graph for Pool B.

The slope of the graph tells you the unit rate in gallons per minute.

Step-by-step explanation:

Solve for x. <br><br> x + 3x + 5 =21
timurjin [86]

Answer:

x=4

Step-by-step explanation:

In order to solve for x, we must isolate x on one side of the equation.

x+3x+5=21

First, combine like terms. x and 3x are both terms with variables, and can be combined.

(x+3x) + 5=21

4x + 5=21

5 is being added to 4x. The inverse of addition is subtraction. Subtract 5 from both sides of the equation.

4x+5-5= 21-5

4x= 16

x is being multiplied by 4. The inverse of multiplication is division. Divide both sides by 4.

4x/4=16/4

x= 16/4

x=4

Let's check our solution. Plug 4 in for x and solve.

x+3x+5=21

4+3(4)+5=21

4+12+5=21

16+5=21

21=21

This solution checks out, so we know our answer is correct.

x is equal to 4, x=4.

Find the zeros of x^2+4x=-10 using the quadratic formula
ipn [44]
X^2+4+10=0
x=(-4(+/-)root16-40)/2, so we now know that the zeros are imaginary, because you can't square root a negative number and 16-40 is -24
so the two roots are…
-2+iroot6 and -2-iroot6
