Answer:

n = 5

Step-by-step explanation:

We have given an equation.

14n= 70

We have to solve above equation by finding the value of n.

Dividing by 14 to both sides of equtaion ,we have

14n/14 = 70/14

As we know that 14 and 70 are multiples of 14.

Hence,

n = 5

Hence, the value of n is 5 in equation 14n = 70.

0.42b-8.3+9.14b=-5.91

Anon25 [30]

Answer:

b= 1421/956

Step-by-step explanation:

9.14b +0.42 = 9.56b
9.56b - 8.3 = 5.91
9.56b= 5.91 +8.3
9.56b = 14.21
Now devide both sides by 9.56
Your Final answer is: b= 1421/956

Write an equation in the variables x and y for the line that passes through the point (4, 7) and that is perpendicular to the li

Brrunno [24]

First of all, we need to find the slope of the given line, writing it in the $y=mx+q$ form and reading the $m$ coefficient:

$2x + 2y = 14 \iff 2y = -2x + 14 \iff y = -x+7$

So, the slope is $-1$

If a line with slope $m'$ is perpendicular to a line with slope $m$ , the following relationship holds:

$mm' = -1$

So, the slope of our line must satisfy

$m(-1) = -1 \iff m=1$

So, we need the equation of a line with slope 1 and passing through (4,7). Given the slope $m$ and a point $(x_0,y_0)$ of a given line, its equation is given by

$y-y_0 = m(x-x_0)$

So, if you plug your values, you have

$y-7=1\cdot(x-4) \iff y = x+3$

Suppose f is a linear function such that f(3 = 5 and f(7 = -4. find the equation for f

NeX [460]

$\displaystyle\\ 
f(3) = 5 \\ 
f(7) = -4\\\\
\texttt{Solve:}\\\\
f(x)=ax+b ~~~\Longleftrightarrow~~~ y=ax+b~~~\Longleftrightarrow~~~ ax+b-y=0\\\\
-------\\
3a+b-5=0~~~(E1)\\ 
7a+b+4=0~~~(E2)\\
---\\
E2 - E1\\
4a+9=0\\
4a =-9\\\\
\boxed{a = -\frac{9}{4} = -2,25}\\\\
3\times \Big(-\frac{9}{4}\Big) + b -5 = 0\\\\
-\frac{27}{4} -5+ b = 0\\\\
\frac{-27-20}{4} + b = 0\\\\
-\frac{47}{4} + b = 0\\\\
\boxed{b = \frac{47}{4} = 11,75}$
