Answer:
f(5)=13 g(8)=12 f(-8)= -26 g(-10)=-15
Step-by-step explanation:
1) 5*3=15
15-2=13
2) 8*.5*3=12
3) -8*3=-24
-24-2= -26
4) -10*.5*3= -15
You seemed to have gotten the equation wrong, but don't worry I'll help you
===================================================================
First you simplify the equation
4=<span><span><span>(-1)</span><span>(-3)</span></span>+b
(A negative times a negative is a positive)
</span>4 = 3 + b
(Flip the equation)
b + 3 = 4
--------------------------------------
Then you subtract 3 from each side
<span><span>b+3-</span>3</span>=<span>4-3
</span>b = 1 is your answer
===================================================================
y = -1x - 7 is wrong as well
To find the answer just add -4 on each side for y+4=-<span>1<span>(x-3)</span></span>
<span>y+4+-4</span>=-<span>x+3+-4
</span>y = -<span><span>x - </span><span>1 is the answer
</span></span>To graph, plot points on Y-intercept of -1 and place another point at (-2,1)
9x8y12 it a lot of work to do so I don't want to type how to do the problem
Subtraction:
2115 (20:15) - 0830 (8:30) = 20:75 - 8:30 = 12:45 P.m. = 1245
Hope it helped,
Happy homework/ study/ exam!
-3(is less than)1 and 5(is less than or equal to) 25
