Answer:

y=(x/2)+5

Step-by-step explanation:

Slope-intercept form is y=mx+b where m is the slope and b is the y-intercept form. To get that, we need y by itself so we have to add 3x to both sides: 6y=30+3x. Now we divide by 6 and rearrange the right side: y=(3x+30)/6.

y = (3x/6)+(30/6) => y = (x/2)+5. We also know that the slope is 1/2 and the y-intercept is 5 because of the slope-intercept equation.

How many times does the quadratic function intesect the x axis y=2x^+7x+6
atroni [7]

Answer:

There are two intersections

Step-by-step explanation:

The number of intersections can be found by calculating the delta of the equation

Δ=b²-4ac

if Δ=0, there is 1 intersection

if Δ>0 there are 2 intersections

if Δ=<0, there are no intersections

where the quadratic equation is in the form ax²+bx+c

Δ=7²-4(2)(6)

=1>0

There are two intersections

An airplane is flying at an elevation of 5150 ft, directly above a straight highway. Two motorists are driving cars on the highw
Alecsey [184]

Answer:

The cars are 10702ft apart

Step-by-step explanation:

Height of the plane from the high way = 5150ft

Considering Triangle ABD, we will be using SOHCAHTOA

Tan = Opposite/ Adjacent

Tan 54° = Y/5150

Y = 5150*tan54°

Y = 7088 ft

Considering Triangle ADC, Tan = Opposite/ Adjacent is also applicable

Tan 34° = X/5150

X = 5150*tan 54°

X = 3614ft

The distance between the two cars = (X+Y)

= 7088 + 3614

= 10702ft
