Answer:
Step-by-step explanation:
The equation of the line in point-slope form is:
Where m is the slope and is a point of the line.
The slopes of two perpendicular lines are opposite reciprocal, then the other slope is:
m=
Substitute the slope and the given point into the equation, then you obtain:
Answer:
t=2
j=1
Step-by-step explanation:
3 tacos and a juice is $7
3t+j=7
4 tacos and 2 juices is $10
4t+2j=10
We have a simultaneous equation. It can be solved either by substitution method or Elimination method. For the purpose of this question, the elimination method will be used
3t+j=7 Equation 1
4t+2j=10 Equation 2
To eliminate j, we multiply Equation 1 by 2, the coefficient of j in equation 2, so that in both equations, j can have the same coefficient.
2(3t+j=7)
6t+2j=14 Equation 3
We now have
4t+2j=10 Equation 2
6t+2j=14 Equation 3
We subtract equation 2 from equation 3, to eliminate j
6t-4t=2t
2j-2j=0
14-10=4
We have 2t=4
Divide both sides by 2
2t/2=4/2
t=4/2
t=2
Substitute t for 2 in equation 1, to get j
3t+j=7
3(2)+j=7
6+j=7
j=7-6
j=1
One taco cost $2 while 1 juice cost $2

Answer:
I think it is 75 square inches
Step-by-step explanation:
I believe this because if the base is a square, in order to find the area of a square it is base times height so in this case 5*5. So we have 25 for the base and to find the area of each triangle it is base times height divided by 2 and in this case (5*5)/2 which is 12.5. So since their are 4 triangles it is 12.5*4 which is 50 and plus the base area which is 25, so the ANSWER is 75 square inches.
<em>square root of 517 = 22.7376</em>
