To solve this system of equations, start by plugging your equation for x wherever x appears in your second equation, giving you (y-3)+3y=13. Now, combine like terms, (y-3)+3y=13 => 4y-3=13, solve for y by adding 3, 4y-3=12 => 4y=16, divide by 4, 4y=16 => y=4. Now that you have your y value, plug it into the equation for x to get the x value, x=y-3=4-3=1. This makes your solution (1,4), answer choice A
Answer:
only A is correct
Step-by-step explanation:
To get the equation of the given line, we just have to see if the point given fits into any of the equation
The given point is (15,3)
a) y = 1/5x = 1/5 * 15 = 3
This is correct
b) y = -5(-75) = -375; this is not correct
c) y = 3x
y = 3(15) = 45
This is not correct
d) y = 15x
y = 15(15) = 225
This is incorrect
e) y = -1/5x
y = -1/5 * 15 = -3
This is incorrect
f) y = 5x
y = 5(15) = 75
This is also incorrect
Steps:
32yd. * 15yd. = 480 sq. yd
96 sq. yd. + 480 sq. yd = 576
Description:
We know that the prism is 13 yards long with a base of 12 yards and height of 8 yards. Meaning.
H = height
B = Base
P= Prism
The area of the prism each is 12yd * 8yd/2 = 48. So the two triangle combined area will be 96 yd. Meaning we get the number 32yd times it by 8 divide by 2 = the answer will equal as 48yd .The perimeter of both identical, isosceles triangles triangles are 10yd. + 10yd. + 12yd. = 32yd. and the length of those sides is 15yd. So the last step is to 32yd. * 15yd. = 480 sq. yd. Now you combine the two areas yields the total
. 96 sq. yd. + 480 sq. yd = 576 sq. yd. total Answer will come as 576. Meanign the correct answer for this question is 576 yd.
Answer: 576 sq. yd. total
