Answer:
y=-2x+1
Step-by-step explanation:
Perpendicular lines have slopes that are negative reciprocals of one another. slope 1/2 perpendicular will be -2/1=-2
y-5=-2(x-(-2))
y-5=-2(x+2)
y-5=-2x-4
y=-2x-4+5
y=-2x+1
The answer is YON. x-intercept = (-1, 0)
y-intercept = (0, -3)
When you are writing an intercept, the other variable is 0.
For x-intercepts: (x, 0)
For y-intercepts: (0, y)

Answer:
7%
Step-by-step explanation:
Let x represent the percentage of water in the mix. The amount of water in the mix is ...
5%·120 +10%·80 = x·(120 +80)
14/200 = x = 7% . . . . . . . . . . . . . . simplify, divide by 200
The percentage of water in the mixture is 7%.
Answer:
(A)A triangle with angles 45 degrees, 45 degrees, and 90 degrees. 2 sides are congruent.
Step-by-step explanation:
If Javier wants to construct a square by drawing two congruent triangles.
- One of the angle of the triangle must be equal to 90 degrees to form one of the vertex of the square.
- The other two sides of the triangle must be equal(congruent) to form the two adjacent side lengths of the square. This gives rise to an Isosceles Triangle with base angles of 45 degrees each.
Therefore, the triangle which could be used is a triangle with angles 45 degrees, 45 degrees, and 90 degrees.
The correct option is A.
Please use " ^ " to indicate exponentiaton: <span>Use the equation
350 = (270)(1.05)^x.
Take the log of both sides:
log 350 = log 270 + x*log 1.05.
Subtr. log 270 from both sides:
log 350 - log 270 = x*log 1.05
log 350 - log 270
Sove for x: x = -------------------------
log 1.05
2.544- 2.431
Evaluate this using a calculator. x = ------------------
0.0212
x is then approx. 5.33, or 5 1/3 years.
