Answer:

p(- 3) = - 79

Step-by-step explanation:

Substitute x = - 3 into p(x) , that is

p(- 3) = 4(- 3)³ + 2(- 3)² - 3(- 3) + 2

        = 4(- 27) + 2(9) + 9 + 2

       = - 108 + 18 + 11

      = - 108 + 29

     = -  79

Answer:

[tex] x_{1} = - \sqrt{2} \: .\: x_{2} = - 1 \: . \: x_{3} = 1 \: . \: x_{4} = \sqrt{2} [/tex]

Step-by-step explanation:

x⁴ - 3x² + 2 = 0

x^2×2 - 3x² + 2 = 0

(x²)² - 3x² + 2 = 0

t² - 3t + 2 = 0

t = 1, t = 2

x² = 1, x² = 2

x = -1, x = 1

x = - square root 2, x = square root 2

[tex] x_{1} = - \sqrt{2} \: .\: x_{2} = - 1 \: . \: x_{3} = 1 \: . \: x_{4} = \sqrt{2} [/tex]

Answer:

5 miles = 8 Hrs

X = 1Hr

5 Miles × 1 Hr = X × 8Hrs

5 Miles × 1 Hr = X

8Hrs

5 Miles = X

8

X = 0.625 Miles

so we can conclude that George Travels

0.625 Miles Per Hour or 0.625 M/Hr

Answer:

[tex]y=\frac{1}{2} x-40[/tex]

Step-by-step explanation:

Slope interccept form: y=mx+b

(m= the slope, b= the y-intercept (the y value when x=0))

for every 2 x-values the y-value increases by 1. Slope is written as  [tex]\frac{rise}{run}[/tex] or  [tex]\frac{y_{1}-y_{2} }{x_{1}-x_{2}}[/tex] which is the change in the y-values divided by the change in x-values. You can find the slope by plugging in points.

[tex]\frac{(-42)-(-41)}{(-2)-(-4)} =\frac{1}{2\\}[/tex]     so now you have [tex]y=\frac{1}{2}x+b[/tex]

b is whatever the value of y is when x=0. According to the table when x=0 then y=-40. The final equation is [tex]y=\frac{1}{2} x-40[/tex]

Answer: 1 degree Fahrenheit

Step-by-step explanation:

The temperature starts at -10 degrees F, so if in two hours, the temperature has risen by 4 degrees, then the new temperature is -10 + 4 = -6 degrees F. 3 hours later, the temperature has risen another 7 degrees, so the new temperature is -6 + 7 = 1 degrees F. "addition equation" is ambiguous without knowing what class you are taking, but one such equation to represent the situation could be T = -10 + 4 + 7 = 1.

Answer:

[tex]1~3/4[/tex]

Step-by-step explanation:

Let [tex]k[/tex] be the amount of pork Mike uses. Then, he uses [tex]3k[/tex] beef.

We know he uses 7 pounds, of meat so we want to solve [tex]3k+k=7[/tex].

Combining like terms on the left side gives [tex]4k=7[/tex].

We can divide both sides by [tex]4[/tex] to get [tex]k=7/4=1~3/4[/tex].

So, the answer is [tex]\boxed{1~3/4}[/tex].

Step-by-step explanation:

10+14+24+28=76 miles long

Answer:Yes

Step-by-step explanation:

The solution provided is complete and includes all the steps needed to solve the problem.

The first step is to calculate the area of the square patio by multiplying the length of one side by itself:

10.5 x 10.5 = 110.25.

The second step is to divide the area of the patio by the area of each individual stone to determine the number of stones needed:

110.25 ÷ 1.5 = 73.5.

Since it is not possible to have a fraction of a stone, the answer should be rounded up to the nearest whole number, which is 74.

Therefore, there are 74 stones on the patio.

Answer:

Step-by-step explanation:

12 + 0.05m = 63.80

12 + 1m/20 = 63.8

12 + m/20 = 63.8

(20 * 12)/20 + m/20 = 63.8

(20 * 12 + m)/20 = 63.8

(m + 240)/20 = 63.8

20((m + 240)/20) = 63.8

m + 240 = 20 * 63.8

m + 240 = 1276

m = 1276 - 240

m = 1036

Answer:

x=24°

Step-by-step explanation:

(3x-6)°+x°= 90°

4x=90+6

4x= 96°

x= 24°

Answer:

Step-by-step explanation:

(3x-6)°+x°=90°

First, combine like terms:

3x°+x°-6°=90°

4x°-6°=90°

Add 6° to both sides:

4x°=96°

Divide 4 from both sides to isolate x:

x=24°

Check your answer:

3(24)-6+(24)=90°

72-6+24=90°

66+24=90°

90°=90° (correct)
