3. replace x with 4 and solve:

3(4) - 5 = 12 -5 = 7

The answer is 7

4. Replace x with 6 in the equation for g(x) first:

2(6) -5 = 12-5 = 7

Now replace x with 7 in the equation for f(x)

2(7) +1 = 14 +1 = 15

The answer is 15

Which expression is equivalent to sin(1.8x) sin(0.5x)?
Rasek [7]
Hum, this problem was difficult. You use the next expression to solve this problem. \[\cos (A - B) = \cos A \cos B + \sin A \sin B \] \[\cos (A + B) = \cos A \cos B - \sin A \sin B\] \[\cos (A - B ) - \cos (A +B ) =2 \sin A \sin B\] So \[\sin A \sin B = 0.5 \left( \cos(A - B) - \cos(A + B) \right)\] A = 1.8 x, B = 0.5 x \[\sin (1.8x) \sin (0.5x) = 0.5\left( \cos(1.8-0.5)x - \cos(1.8+0.5)x \right)\]\[= 0.5 \left( \cos(1.3x) - \cos (2.3x) \right)\] It's finish !!

Write an equation in slope intercept form for the line with slope negative three fourths and y intercept of negative one
Stells [14]

The slope intercept form is y=-\frac{-3x}{4}-1.

Solution:

Given data: slope = -\frac{3}{4} and y-intercept = –1

y-intercept means (x, y) = (0, –1)

Equation of a line for slope intercept form: y-y_1=m(x-x_1)

Here, x_1=0, y_1=-1 and m=-\frac{3}{4}.

⇒ y-(-1)=\frac{-3}{4} (x-0)

⇒ y+1=\frac{-3}{4} (x)

Do cross multiplication.

⇒ 4(y+1)=-3x

⇒ 4y+4=-3x

⇒ 4y=-3x-4

Divide both sides of the equation by 4.

⇒ y=-\frac{-3x}{4}-\frac{4}{4}

⇒ y=-\frac{-3x}{4}-1

Hence the slope intercept form is y=-\frac{-3x}{4}-1.
