7. What is the value of t?
t=
Answer:
t = -3
Step-by-step explanation:
To answer this problem, first you have to know how to calculate the slope of a line. Since we know that y1-y2/x1-x2 is the equation to calculate slope, we are ready to tackle this problem.
Because y1 is t, y2 is 4, x1 is 4, and x2 is 5, we can now plug this in to our equation. The equation becomes t-4/4-5. And because we know the slope is 7, the equation is now (t-4)/(4-5)=7. If you solve this equation, you will get that t=-3
Answer:
Final answer is x=90,
Step-by-step explanation:
Given equations are:
-x-4y=37 ...(i)
-2x-4y=-53 ...(ii)
multiply (ii) by -1
2x+4y=53 ...(iii)
Add (i) and (iii)
x=90
plug value of x=90 into (i)
-x-4y=37
-90-4y=37
-4y=37+90
-4y=127
Hence final answer is x=90,
Answer:
X=90, y =-127/4
Step-by-step explanation:
Subtract the second equation from the first and you get X+ 0y= 90. Replace x=90 in either equation and you get y= -127/4.
Answer:
1) 3<x≤15
2) w>-3
3) t>2 and t<-6
4) q<-15 and q≥-3
5) -6<p<5
Step-by-step explanation:
I will solve one problem to show you.
1) -2<x-5≤10
add 5 on both sides
-2+5<x-5+5≤10+5
3<x<15
