Factorise the 5
5m + 5n = 5(m+n)

AURORKA [14]3 years ago
3 0

In this question , we have to rewrite the given expression by grouping and the expression is

5m +5n

First we have to check what is common here. And as we see that 5 is there with both terms. So the common factor is 5 here.

And on taking out 5 , we will get

5m +5n = 5(m+n)

And that's the required factored form.

f(x) = 20(1.5)x. Let your dependent variable in the function be y. Write the function that models the independent variable in te
mars1129 [50]

Answer:

x=log_{1.5}(\frac{y}{20})

Step-by-step explanation:

Considering the function:

f(x) = 20\, (1.5)^x

The independent variable is "x" and we are asked to model it in terms of the variable "y":

f(x) = 20\, (1.5)^x\\y=20\, (1.5)^x

Then, in order to solve for x (which resides in the exponent), we need to use the logarithm function.

Since the base of the exponent is 1.5, we need to use the logarithm base 1.5, to lower that exponent "x":

y=20\, (1.5)^x\\\frac{y}{20} =(1.5)^x\\log_{1.5}(\frac{y}{20}) =x\\x=log_{1.5}(\frac{y}{20})

Find the value of x in the quadrilateral below.
Ket [755]

Answer:

x=66

Step-by-step explanation:

118+106+70+x=360     The total sum of degrees in a quadrilateral is 360.

294+x=360                  Add the given angle measures together.

x=66                             Subtract 294 from both sides.
