Answer:
The answer is y=4x+14 or C)
Step-by-step explanation:
m=slope To find equation of the line you need to do m=1+3/-3+4 m=4 y-y1=m(x-x1) y+3=4(x+4) y+3=4x+16 y=4x+13
100+25x=250
Subtract 100 from both sides
25x=150
X=6

Answer:
Step-by-step explanation:
hello :
5(x + 7)² = 245
(x + 7)² = 49
x=0 is solution but you have other solution -14 because :(-14+7)² = (-7)² =49
here is an solution Step-by-step :
(x + 7)² = 49 means : (x + 7)² = 7²
(x + 7)² - 7²=0 use identity : a²-b² = (a-b)(a+b)
a=x+7 and b= 7
(x+7-7)(x+7+7) = 0
x(x+14)=0
x=0 or x+14=0
so : x=0 or x= -14
She will drive a total of 247.5 you have to multiply 4.5 times 55 since the question asked how many miles will she drive
First of all, tangents make an angle of 90 degrees with the radius of a circle.
Hence, Both the triangles are right angled.
Now apply pythagorean theorem on triangle LKJ, and find the length of tangent,
which is x= tan(68) * 3 = 7.42
Now, on LMJ to find MJ
so, MJ = 7.42 * tan(61) = 13.39
Hope it helps
