La respuesta es el número 4
y=2
Step-by-step explanation:
Make an equation of straight line by using the formula :y= mx+c
put the x-value of point (2,4) which is 2 and the gradient,m which is 2 into the straight line equation:
y=2x +c
So you need to find the y-intercept to complete the equation, therefore:
when y=0,
0=2(2)+c
c=-4
next the question ask to find the y-coordinate when x =3, therefore you just need to replace x in the equation with 3:
y=2(3)-4
y=4
Width = 5
5x2 = 10 and the length would 13... which is 3 more inches than twice the width
Answer: 749,250
Step-by-step explanation:
700,000 + 40,000= 740,000.
9,000+200+50= 9,250.
740,000 + 9,250 = 740,250.
The angle the radius makes with AB is a right angle, so the Pythagorean theorem applies.
r² = 17.4² - 7² = 253.76
r = √253.76 ≈ 15.9
The length of radius r is about 15.9.
