5 0

Answer:

(-(7-9))(z)-6z= 8(-6+2)

Simplify

-(-2)(z) -6z =8(-6+2)

Multiply 8*-6 and 8*2

2z -6z= -48+16

Combine like terms

2z+-6z =-32

-4z=-32

Divide both sides by -4

z=8

A manager needs to order company shirts for each employee. She was quoted the following rates. If she orders 75 shirts and passe
docker41 [41]
The answer is B.$7.47.

Let's first calculate how much in total 75 shirts cost:
- first 19 (less than 20) cost $10:         19 * $10 = $190
- the next 30 cost $8:                         30 *  $8 = $240
- the rest (26 = 75 - 19 - 30) cost $5: 26 *  $5 = $130

So, in total 75 shirts cost $560:
19 * $10 + 30 * $8 + 21 * $5 = $190 + $240 + $130 = $560

Since 75 shirts are ordered, there must be 75 employees, so each employee must pay $7.47:
$565 ÷ 75 = $7.47

Secants BE and CF intersect at point D inside A. What is the measure of CDE?
Aleks04 [339]
MCE = 360 - (150 + 70 + 50)
mCE = 360 - 270
mCE = 90

<CDE = 1/2(mBE + mCE)
<CDE = 1/2(150 + 90)
<CDE = 1/2(240)
<CDE = 120

answer
<CDE = 120°

If P = (-2,7), Find:<br> Ry-axis (P)<br> ([?], [])
kumpel [21]

Answer:

(2, 7)

Step-by-step explanation:

R_{\text{y-axis}}(\text{P}) represents the reflection of a point P about the y-axis.

If a point (x, y) is reflected across y-axis, rule for the reflection is,

(x, y) → (-x, y)

If a point (-2, 7) follows the same rule, coordinates of the image point will be,

P(-2, 7) → P'(2, 7)

Therefore, answer is (2, 7).
