Coefficient of 24x+32+4x+3

coldgirl [10]

Firstly, you can combine like terms, or terms that have the same variable and exponents.

24x and 4x both have the variable "x" so it can be combined to make 28x

A coefficient is basically just the number that's used to multiply the variable

In this case, the variable is "x" and the number that will be multiplied to x is 28.

<em>The coefficient is 28.</em>

A water balloon is 5 feet above the ground when Sally launches it into the air. Use the quadratic equation 0 = -t^2 + 4t + 5 to

rodikova [14]

Answer:

$t=5\ sec$

Step-by-step explanation:

we have

$-t^{2} +4t+5=0$

Solve the quadratic equation to find the zero's or x-intercepts

Remember that

The x-intercepts are the values of x when the value of y is equal to zero ( water balloon reach the ground)

we know that

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$-t^{2} +4t+5=0$

$a=-1\\b=4\\c=5$

substitute in the formula

$t=\frac{-4(+/-)\sqrt{4^{2}-4(-1)(5)}} {2(-1)}$

$t=\frac{-4(+/-)\sqrt{36}} {-2}$

$t=\frac{-4(+/-)6} {-2}$

$t=\frac{-4(+)6} {-2}=-1$

$t=\frac{-4(-)6} {-2}=5$

therefore

the solution is $t=5\ sec$

Find the sum of -2 9/10 and -5 4/15. Then, in two or more complete sentences, explain the steps you used to add the mixed number

IRINA_888 [86]

Answer:

$\frac{-215}{30}$

Step-by-step explanation:

Given $-2\frac{9}{10} \ and\ -5\frac{4}{15}$

on solving this mixed fraction we get;

$-\frac{29}{10}\ and\ -\frac{64}{15}$

Now adding these fractions by same denominator method.

$-\frac{29\times3}{10\times3} +[-\frac{64\times2}{15\times2} ]\-\frac{87}{30} +[-\frac{128}{30}]\ = -\frac{215}{30}$
