Answer:
line r: y=-2x-2
line s: -2x+1
lime t: -2x+3
Step-by-step explanation:
every slope must be -2 since that's stated in the question
to find b in y=mx+b, you substitute 0 for x and the y coordinate when x is 0 into the equation (for example for slope r, when x is 0 then y is -2, so -2=-2(0)+b) then solve for b (-2=-2(0)+b is -2=b)
basically, b is the y component when x is 0
Answer:
Step-by-step explanation:
23). By applying triangle sum theorem in the given triangle,
(x + 83)° + (x + 48)° + 65° = 180°
2x + 196 = 180
2x = -16
x = -8
Measure of angle A = x + 48
= -8 + 48
= 40°
Therefore, Option A is the answer.
24). By triangle sum theorem,
(3x + 14)° + 90° + (4 + 3x)° = 180°
6x + 108 = 180
6x = 72
x = 12
Measure of angle A = (4 + 3x)
= 4 + 3(12)
= 40°
Therefore, Option A is the answer.
Answer:
Its 10
Step-by-step explanation:
20/15= 4/3
Step-by-step explanation:
<3 = 47°, alternate angle.
<2 = 52° , alternate angle.
<5=180-47-52=81°, linear pair.
<1= 180-52=128°, alternate angle, linear pair.
<4= 180-47= 133°, alternate angle, linear pair.
hope this helps you.
Multiply f(x) by g(x):
= ((1 / (-5x + 19)) + 5) * (1 / (10x - 3))
[first add the 5 to f(x)]
= ((1 + 5 * (-5x + 19)) / (-5x + 19)) * (1 / (10x - 3))
= ((1 -25x + 95) / (-5x + 19)) * (1 / (10x - 3))
= ((96 - 25x) / (-5x + 19)) * (1 / (10x - 3))
= (96 - 25x) / ((-5x + 19) * (10x -3))
= (96 - 25x) / (-50x^2 + 15x + 190x - 57)
= (25x + 96) / (50x^2 + 205x -57)
use the quadratic formula for the denominator: x = (-b ± √(b^2 - 4 *a * c)) / 2a
where for this equation a = 50, b = 205 and c = -57
write the answers in the form (x - answer one) (x - answer two)
then re-write the equation in the form (ax + b) / (cx + d)
