Answer:
Answer is 8 units
Step-by-step explanation:
Answer:
-2.59 = x
Step-by-step explanation:
3+5.25 = 1 - 2.8x
Combine like terms
8.25 = 1-2.8x
Subtract 1 from each side
8.25 -1 = 1-1-2.8x
7.25 = -2.8x
Divide each side by -2.8
7.25/-2.8 = -2.8x/-2.8
-2.589285714 = x
Rounding
x=-2.59
Hey I'm on this question on my test too. I think the answer is:
First Box: "
Reflection across the x-axis"
Last Box: "
Translation 1 unit down"
What the sentence should look like = "<span>
△RST</span><span>
to </span><span>
△<span>
R′</span><span>
S′</span><span>
T′</span></span><span>
is a reflection across the x-axis followed by a translation 1 unit down."
I hope this helps!</span>
Solve first for the solution of the inequalities. This can be done by replacing first the inequalities sign with the equal sign.
x + y = 1
2y = x - 4
The values of x and y from the system of linear equation are 2 and -1. This means that the intersection of the lines should be at point (2, -1).
Substitute 3 to x and determine the value of y from the second inequality.
2y ≥ x - 4
Substituting,
2y ≥ 3 - 4, y ≥ -1/2
Hence, the solution to this item should be the fourth one.
