Answer:
(x, y) =(-6,4)
Step-by-step explanation:
3x-y=-28
-5x-4y=-10
y=3x+28
-5x-4(3x+28)=-10
y=3x+28
-5x-12x-112=-10
y=3x+28
-17x=-10+112
y=3x+28
-17x=102
y=3x+28
x=102/(-17)
y=3x+28
x=-6
y=3*(-6)+28
x=-6
y=-24+28
x=-6
y=4
x=-6
(x,y)=(-6,4)
Answer:
The second base of the trapezoid b2 is 2.5 inches
Step-by-step explanation:
Here, we want to calculate the second base of the trapezoid.
Mathematically, the area of a trapezoid can be given as;
A = 1/2(a + b) h
where a and b represents the parallel bases and h is the height of the trapezoid
so this, we have from the question
1/2(4.5 + b2) * 6 = 21
3(4.5 + b2) = 21
divide both sides by 3
4.5 + b2 = 7
b2 = 7-4.5
b2 = 2.5 inches
PQRST, as similarity refers to these polygons all having the same shape, just in different sizes and positions. Polygon PQRST, however, is a different shape than the other ones, as it is wider in comparison to the height.
The <em><u>correct answer</u></em> is:
Social Security.
Explanation:
By law, every person must pay into Social Security when they get a job.
Social Security was developed by Franklin Roosevelt during the 1930s. It was created with the intention of creating a pension for all working people, regardless of the job they work. For this reason, everyone pays in to Social Security while they work and can draw it at retirement.
