Solving systems of equations using substitution. y=2x+8. y=5-x

kherson [118]

Answer:

(x, y) = (-1, 6)

Step-by-step explanation:

y = 2x + 8

y = 5 - x

Substituting the second equation into the first equation, we get:

5 - x = 2x + 8

5 = 3x + 8

-3 = 3x

x = -1.

So, y = 5 - (-1).

Simplifying, we get:

y = 6.

If 3x + y = 18, then 2(3x +y) =__________ (1 point) 36 2. if x =5, then 2x +5 is how much more than x?__________ (1 point) 10 3.

bogdanovich [222]

If 3x + 8 = 18, then 2(3x + y) = 36
if x = 5, then 2x + 5 is 10 more then x
if x + y = 12, then 3x + 3y = 36
if 5.353 = 53k, then k = 0.101
if x = 3.6 and y = 6.4, then 100(x + y) = 1000

Find the length of midsegment YZ in trapezoid ABCD when A(-5,-6) B(-6,-2) C(-4,0) and D(3,2)

Luda [366]

Answer:

Option C

Step-by-step explanation:

Since, Y and Z are the midpoints of sides AB and CD of the given trapezoid.

Segment YZ will the midsegment of trapezoid ABCD.

By the theorem of midsegment,

m(YZ) = $\frac{1}{2}(AD+BC)$

By using expression for the length of a segment between two points,

Length of a segment = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Distance between two points A(-5, -6) and D(3, 2),

AD = $\sqrt{(3+5)^2+(2+6)^2}$

AD = $\sqrt{64+64}$

AD = $\sqrt{128}$

AD = $8\sqrt{2}$

Distance between B(-6, -2) and C(-4, 0)

BC = $\sqrt{(-6+4)^2+(-2-0)^2}$

BC = $\sqrt{8}$

BC = $2\sqrt{2}$

Therefore, m(YZ) = $\frac{1}{2}(8\sqrt{2}+2\sqrt{2})$

= $\frac{1}{2} (10\sqrt{2})$

= $5\sqrt{2}$

Option C will be the answer.

When evaluating a survey, Jody saw that 54% of the respondents think that the minimum age of those awarded a driver's license sh

zhuklara [117]

Since the margin of error is 5%, the minimum of supporters will be less than the maximum of disapprovers.

So the third option will be correct. You cannot make certain conclusions based on this survey.
