Answer:

  x ≤ 1

Step-by-step explanation:

Swapping sides of the inequality requires reversing its sense.

If 1 is greater than x, then x is less than 1.

Sheila has 11
RSB [31]

Answer:

6

Step-by-step explanation:

11 1/2 = 11.5

2 1/4 = 2.25

11.5 ÷ 2.25= 5.11

she needs 6 containers because you round up 5.11 to 6.

if your doing the work in fractions rather decimals let me know and I can explain it that way too

H1:p>0.5

Sample proportion=492/792=0.6276

Test statistic:

z=(0.6276-0.5)/sqrt(0.5*(1-0.5)/784)

z=7.14

p-value=P(z>7.14)=0

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.
const2013 [10]

Answer:

y + 12 = 3(x - 2)

Step-by-step explanation:

Insert the coordinates into the formula with their CORRECT signs. Remember, in the Point-Slope Formula, <em>y</em><em> </em><em>-</em><em> </em><em>y</em><em>₁</em><em> </em><em>=</em><em> </em><em>m</em><em>(</em><em>x</em><em> </em><em>-</em><em> </em><em>x</em><em>₁</em><em>)</em><em>,</em><em> </em>all the negative symbols give the OPPOSITE term of what they really are. Since both lines contain have to have similar <em>rate of changes</em> [<em>slopes</em>], we do not go any further.

In the triangle, x is 5 greater than y, and y is 21 less than three times z, and the perimeter is 180. What is the value of each
svetlana [45]

Answer:

x = 77

y = 72

z = 31

Step-by-step explanation:

The formula for the Perimeter of triangle XYZ = x + y + z

From the question:

x + y + z = 180

In the triangle, x is 5 greater than y,

x = y + 5

y is 21 less than three times z

y = 3z - 21

3z = y + 21

z = y + 21/3

Hence:using substitution

x + y + z = 180

y + 5 + y + y/3 + 21/3 = 180

2y + y/3 + 5 + 21/3 = 180

2y + y/3 = 180 - ( 5 + 21/3)

2y + y/3 = 180 - (5 + 7)

2y + y/3 = 180 - 12

2y + y/3 = 168

Multiply both sides by 3

2y × 3 + y/3 × 3 = 168 × 3

6y + y = 504

7y = 504

y = 504/7

y = 72

Solving for x

x = y + 5

x = 72 + 5

x = 77

Solving for z

z = (y + 21)/3

z = (72 + 21)/3

z = 93/3

z = 31

Therefore,

x = 77

y = 72

z = 31
