Answer:
19
Step-by-step explanation:
The option second D: [–5, 7]; R: [–5, 1] is correct the domain is D: [–5, 7], and the range is R: [–5, 1]
<h3>What is an ellipse?</h3>
An ellipse is a locus of a point that moves in a plane such that the sum of its distances from the two points called focus adds up to a constant. It is taken from the cone by cutting it at an angle.
We have an ellipse equation:
![\rm x^{2}+4y^{2}-2x+16y-19=0](https://tex.z-dn.net/?f=%5Crm%20x%5E%7B2%7D%2B4y%5E%7B2%7D-2x%2B16y-19%3D0)
We can write the above equation as:
![\rm \dfrac{\left(x-1\right)^{2}}{36}+\dfrac{\left(y+2\right)^{2}}{9}=1](https://tex.z-dn.net/?f=%5Crm%20%5Cdfrac%7B%5Cleft%28x-1%5Cright%29%5E%7B2%7D%7D%7B36%7D%2B%5Cdfrac%7B%5Cleft%28y%2B2%5Cright%29%5E%7B2%7D%7D%7B9%7D%3D1)
The domain will be:
D: [–5, 7]
The range will be:
R: [–5, 1]
Thus, the option second D: [–5, 7]; R: [–5, 1] is correct the domain is D: [–5, 7] and the range is R: [–5, 1]

Hello there.
<span>Which line is a graph of the equation 2x + 5y = 10?
Coordinate plane with the following lines graphed: Line A contains a slope of five-halves and y-intercept of 2; Line B contains a slope of negative five-halves and y-intercept of 2; Line C contains a slope of five-halves and y-intercept of negative 2; and Line D contains a slope of negative five-halves and y-intercept of negative 2.

10.5 hours
let t be time then distance travelled by both is
Mr Burges ⇔ d = 50t ( distance = speed × time )
Mrs Burges ⇒ d = 70(t - 3)
At the point of overtaking both will have travelled the same distance
equating their distance and solving for t
70(t - 3) = 50t
70t - 210 = 50t ( subtract 50t from both sides )
20t - 210 = 0 ( add 210 to both sides )
20t = 210 ( divide both sides by 20 )
t = 10.5 hours
Answer:
You have to have the graph to answer it.
