Answer:

£200

Step-by-step explanation:

Sum the parts of the ratio, 3 + 4 = 7 parts

Divide the amount by 7 to find the value of one part of the ratio

£350 ÷ 7 = £50 ← value of 1 part of the ratio , then

4 parts = 4 × £50 = £200 ← amount Dave gets

Find the X-Intercepts of <br> y=-x^2-2x+1

bekas [8.4K]

Answer:

(1,0)

Step-by-step explanation:

we can't factor this so we'll use the quadratic formula

$\frac{-b+\sqrt{b^2-4ac} }{2a}\\\frac{-b-\sqrt{b^2-4ac} }{2a}$

(use both of them because usually there are two zeroes)

We have

$\frac{2+\sqrt{4-4}}{2}=\frac{2}{2}=1$

Therefore the x intercept is just (1,0)
