Answer:

y+4 = 2(x+3)

Step-by-step explanation:

We have 2 points so we can find the slope

m = (y2-y1)/ (x2-x1)

= (2--4)/(0--3)

= (2+4)/(0+3)

= 6/3

= 2

We want to use the point slope form of the equation for a line

y-y1 = m(x-x1)

We know the slope =2 and the point (0,2)

y-2 = 2(x-0)

y-2 = 2x

We could also use the other point (-3,-4)

y--4 = 2(x--3)

y+4 = 2(x+3)

√7.5×√3.5 step and answer

irina1246 [14]

Answer:

√105/2

Step-by-step explanation:

Given the surd expression √7.5×√3.5, this can also be expressed as;

√7.5×√3.5

= √75/10 × √35/10

= √(75×35)/10×`10

=√105×25/100

= 5√105/√100

=5√105/10

=√105/2

Hence the required expression a √105/2

Solve for < x < 180degrees

Tamiku [17]

Option C: 90° is the value of x.

Explanation:

The given expression is $4+2 \sin x=14-8 \sin x$ for $0^{\circ} \leq x \leq 180^{\circ}$

We need to solve the expression.

Thus, we have,

$4+2 \sin x=14-8 \sin x$

Subtracting both sides by 4, we have,

$2 \sin x=10-8 \sin x$

Adding both sides by 8 sin x, we get,

$10 \sin x=10$

Dividing both sides by 10, we have,

$sin \ x=1$

Taking $sin^{-1}$ on both sides of the equation, we get,

$x=sin^{-1}(1)$

$x=90^{\circ}$

Thus, the value of x is 90°

Hence, Option C is the correct answer.
