So fill out the coordinate with those given numbers, and count how far apart they are and you will get your answer. Then times it by x.
Answer:
42.5m/s
Step-by-step explanation:
Divide by 40
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
Answer:
answer would be the first choice.
Step-by-step explanation:
you would need to factor out x from the expression, then factor out -3 from the expression, factor the expression using a^2-B^2=(a-b)(a+b), afterwards you factor out the 4 from the expression, and then the 3x. Next you would factor out 2x+1, reduce the expression with x-5, reduce the numbers with the greatest common divisor 2, you then reduce the expression with x-3, multiply the fractions, distribute 2 through the parenthesis, distribute the 3x through the parenthesis, and that should be all.
Answer:
16 square inches
16 inches
Step-by-step explanation:
We know the area formula is A = s² and the perimeter formula is P = 4s, where s is the side length.
Here, s = 4, so plug this value into both equations:
A = s²
A = 4² = 16 square inches
P = 4s
P = 4 * 4 = 16 inches
Both blanks are 16.
