Mathematics

Answer:

(4, 1 )

Step-by-step explanation:

y = 2x - 7 → (1)

y = - x + 5 → (2)

substitute y = 2x - 7 into (2)

2x - 7 = - x + 5 ( add x to both sides )

3x - 7 = 5 ( add 7 to both sides )

3x = 12 ( divide both sides by 3 )

x = 4

substitute x = 4 into either of the 2 equations

substituting into (2)

y = - 4 + 5 = 1

solution is (4, 1 )

1/5 (5x-15) -2x What is the question ?? How do I solve the problem ??

Ksenya-84 [330]

Answer:

$-x-3$

Step-by-step explanation:

They want you to simplify the expression.

Step 1: Apply the distributive property.

$\frac{1}{5} (5x)+\frac{1}{5} (-15-2x)$

Step 2: Cancel the common factor of 5.

$x+\frac{1}{5} (-15-2x)$

Step 3: Cancel the common factor of 5.

$x-3-2x$

Step 4: Subtract 2x from x.

$-x-3$

Find the measure of the arc or angle indicated. NO LINKS.

Advocard [28]

Answer:

10. A) 120°

11. D) 40°

12. D) 54°

13. A) 101°

Step-by-step explanation:

The applicable rules of angles and arcs are ...

the whole is the sum of the parts
arcs of a circle total 360°
an inscribed angle intercepts an arc of twice its measure

10) Angles C and L intercept the same arc (DE) so will have the same measure.

15x = 16x -4

4 = x . . . . . . . . add 4-15x

arc DE = 2(15x) = 30(4) = 120 . . . degrees

11) Arc VW is twice the measure of angle X, so ...

9x +8 = 2(5x)

8 = x . . . . . . . . . subtract 9x

∠VXW = 5x = 5(8) = 40 . . . degrees

12) Arc EFG is twice the measure of angle W, so ...

70° +FG = 2(88°)

FG = 106° . . . . . . . . . subtract 70°

Arc FGW is twice the measure of angle E, so ...

106° +GW = 2(80°)

GW = 54° . . . . . . . . . . subtract 106°

13) Arc ST is twice the measure of angle R. The sum of arcs is 360°.

RS +ST +TR = 360°

119° +2(70°) +TR = 360°

TR = 101° . . . . . . . . subtract 259°
