2(4u-5)=70
divide 2 from both sides
4u-5=35
add 5 to both sides
4u=40
divide 4 from both sides
u=10

Can someone please help me asappp I’ll mark brainlist !!!

Answer:

D. y = 76x

Step-by-step explanation:

First you find the gradient, by using the gradient formula

rise over run

380 - 228

---------------- <- division sign

5 - 3

152/2 = 76

Hence y = 76x + c

Find c by subbing points in. I am going to use this as an example (5, 380)

380 = 76(5) + c

380 -380 = c

c = 0

Hence, y = 76x

Answer:

$\frac{29}{18} = 1 \frac{11}{18}$

Step-by-step explanation:

To solve this question, we definitely need to make w the subject.

$w - \frac{5}{6} = \frac{7}{9} \\ w - \frac{5}{6} + \frac{5}{6} = \frac{7}{9} + \frac{5}{6} \\ w = \frac{29}{18} \\ = 1 \frac{11}{18}$

True or false:

Gala2k [10]

1. False. $f'(c)=0$ does not necessarily mean that $f(c)$ is a maximum or minimum. It could just as easily be a saddle point. For example, consider the function $f(x)=x^3$ with $f'(x)=3x^2=0$ when $x=0$ , yet $f(x)$ for $x$ and $f(x)>0$ for $x>0$ .
