Answer:

-2

Step-by-step explanation:

Based on PEMDAS (parenthesis, exponent, multiplication, division, addition, subtraction), you have to do -2 to the power of 4 first.

-2 x -2 x -2 x -2 = 16

Then, you have to multiply 16 by -0.125. After multiplying, you get -2.

Answer:

1) The value of c is given by

$c=4$

2) The value of k is given by

$k=-4150$

Step-by-step explanation:

Given that function g is defined by $g(x)=cx-3$ , where c is a constant.

To find c:

Also given that value of g(x) at x=0.5 is equal to -1

ie., $g(0.5)=-1$

At x=0.5

$g(0.5)=c(0.5)-3=-1$

$(0.5)c-3=-1$

$(0.5)c=-1+3$

$(0.5)c=2$

$c=\frac{2}{0.5}$

$c=\frac{2}{\tfrac{1}{2}}=2\times \frac{2}{1}$

Therefore $c=4$

2) Given that function h is defined by $h(x)=\frac{20x-k}{x+50}$ , where k is a constant.

To find k:

Also given that value of h(x) at x=20 is equal to 65

ie., $h(20)=65$

At x=20

$h(20)=\frac{20(20)-k}{20+50}=65$

$400-k=65(70)$

$-k=4550-400$

$-k=4150$

Therefore $k=-4150$

What is the equation, in slope-intercept form, of the line that is perpendicular to the line

wolverine [178]

Answer:

y=3/2x+1

Step-by-step explanation:

y-4= -⅔(x-6)

y-4=-⅔x+4

y=-⅔x+4+4

(equation of line 1) y= -⅔x+8 gradient= -⅔

(line 2)gradient=3/2

note* the gradients of perpendicular lines multiplied result to -1

gradient=y²-y²

x²-x¹

3 =y+2

2. x+2

multiply both sides by 2(x+2)to remove the denominators

3(x+2)=2(y+2)

3x+6=2y+4

3x+6-4=2y

3x+2=2y

divide all sides by 2

3/2x+1=y

y=3/2x+1
