$3x^2-5x+ 7 = 0 \\ D=b^2-4ac=(-5)^2-4*3*7=25-84=-59 \\ D\ \textless \ 0 \ \ \to \ \ The \ equation \ has \ no \ roots$

3x²-5x+7=0

this equation doesn't have real roots.
So we have to apply the quadratic formula.
x= -b±√b²-4ac/2a
On putting the values, we will get our roots as
5+59i/6 and 5-59i/6

Nesterboy [21]

D = rt

We are given the rate r to be 15 mph.

We are given the time (in hours) to be 3.5.

We need to find D.

D = (15)(3.5)

D = 52.5 miles.

What is the slope of the line 6x + y = 24?

ValentinkaMS [17]

Answer:

-6

Step-by-step explanation:

You need to get it in Point-Slope form, or

y = mx + b

Isolate y by subtracting 6x

You are left with:

y = -6x + 24

M is the slope, so in this case, it is -6

Mr. West is standing on a cliff that is 25 1/5meters above the surface of the ocean. He spots a dolphin that is 2 3/5 meters und

zhenek [66]

Answer:

Total distance from Mr. West to dolphin $=27\frac{4}{5}\ meters$

Step-by-step explanation:

Height of cliff on which Mr. West is standing above the surface of ocean = $25 \frac{1}{5} \ meters$

Mr. West spot the dolphin under the water at a depth of = $2\frac{3}{5} \ meters$

∴ Total distance from Mr. West to dolphin= $(25 \frac{1}{5}+2\frac{3}{5})\ meters$

Adding mixed numbers

$(25 \frac{1}{5}+2\frac{3}{5})$

Adding whole numbers first.

$=25+2+\frac{1}{5}+\frac{3}{5}\\=27+\frac{1}{5}+\frac{3}{5}$

Adding fractions by taking LCD.

$=27+\frac{1+3}{5}\\=27+\frac{4}{5}\\=27\frac{4}{5}\ meters$

PLEASE HELP:)))))))))

slava [35]

Answer:

see explanation

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , thus

y = 180° - (55 + 41)° = 180° - 96° = 84°

z and y are adjacent angles and supplementary, thus

z = 180° - 84° = 96°

x and 109° are alternate exterior angles and congruent, thus

x = 109°
