3.) 2x + 4 = -3x - 2; x = 1 Determine if the value of x is a solution to the equation

guajiro [1.7K]

Answer:

x = 1 is not a solution to the equation

Step-by-step explanation:

2x + 4 = -3x - 2 x = 1

2(1) + 4 = -3(1) - 2

2 + 4 = -3 - 2

Solve for x: x2 + 8x = -1

olga nikolaevna [1]

$x^2+8x=-1\\
x^2+8x+16-16=-1\\
(x+4)^2=15\\
x+4=\sqrt{15} \vee x+4=-\sqrt{15}\\
x=-4+\sqrt{15} \vee x=-4-\sqrt{15}$

Answer: D

Step-by-step explanation:

First I would write out the points of the x and y intercepts and then I would write out an equation in slope-intercept form (y=mx+b). From there I would move my terms accordingly to make it into standard form and compare my answer! Hope this helped!

The approximate height, h, in meters, traveled by golf balls hit with two different clubs over a horizontal distance of d meters

inna [77]

Answer:

a) 100 metres

b) 10 metres

Step-by-step explanation:

Given: the approximate height, h, in meters, travelled by golf balls hit with two different clubs over a horizontal distance of d meters is given by the functions: $h=-0.002d^2+0.3d\,,\,h=-0.004d^2+0.5d$

To find: distances when the ball is at the same height when either of the clubs are used. Also, to find this height

Solution:

(a)

$-0.002d^2+0.3d=-0.004d^2+0.5d\\d(-0.002d+0.3)=d(-0.004d+0.5)\\-0.002d+0.004d=0.5-0.3\\0.002d=0.2\\d=\frac{0.2}{0.002}=100\,\,metres$

(b)

Put d = 100 in $h=-0.002d^2+0.3d$

$h=-0.002(100)^2+0.3(100)\\=-20+30\\=10\,\,metres$
