Please help i have exam tom.

Xelga [282]

Answer:

Step-by-step explanation:

this is a simultaneous equation question

f(1)=8 so a(1) + b = 8

f(4)=17 so a(4) + b = 17

can you figure this out from here ???

if you can't below is how to solve it

a + b = 8

4a+b=17

multiply the top equation by 4 and then subtract the bottom one from the top

4a+4b = 32

-(4a +b = 17)

3b = 15

b=5

now plug 5 into the first equation

a + 5 = 8

a=3

there you go :)

1 (-2,2) Write the equation, in point-slope form, of the line that is perpendicular to the given line and passes through the poi

lozanna [386]

Answer:

y = -5x - 8

Step-by-step explanation:

Take the points (-5,-4) and (0,-3) plug them into this formula to get the slope.

$\frac{y2 - y1 }{x2 - x1}$

Now plug in your points

$\frac{-3 - (-4)}{0 - (-5)} \\\\\frac{1}{5}$

Since you're slope is 1/5 the slope of the perpendicular line is going to be the totally opposite -5 is the slope of the perpendicular line.

Now plug in -5 and the point (-2,2) into y = mx + b to get the y-intercept

2 = -5(-2) + b (b represents the y-intercept)

2 = 10 + b (subtract 10 from both sides)

-8 = b

The perpendicular line looks like this y = -5x - 8

Hope this helps ya! Keep smiling!
