Answer:

5y=50

Step-by-step explanation:

3y - 8 = 22, right? So y would equal to 10 because 3x10 is 30 and 30 minus 8 is 22. Then you times 5 by 10 and get 50.

Answer:

y - 5= -3(x + 2)

Step-by-step explanation:

Step-by-step explanation:

to solve for a,

f(-1) = 5

a(-1)^2 + 1 = 5

a + 1 = 5, so a=4

The required value is [tex]a=4[/tex]

The given point is (-1,5)

And the graph is [tex]f(x)=ax^2+1[/tex]

Now, substituting the point into the given equation we get,

[tex]f(-1)=a(-1)^2+1=5\\a+1=5\\a=5-1\\a=4[/tex]

So, the required value is [tex]a=4[/tex].

Explanation:

Finding the square root of a number is the inverse operation of squaring that number. Remember, the square of a number is that number times itself. The perfect squares are the squares of the whole numbers. The square root of a number, n, written below is the number that gives n when multiplied by itself.

Step-by-step explanation:

Evaluate

[tex](1+\sqrt{2})^3 + (1-\sqrt{2})^3[/tex]

As we have the Cube binomials:

[tex]\boxed{(a+b)^3=a^3+3a^2b+3ab^2+b^3}[/tex]

[tex]\boxed{(a-b)^3=a^3-3a^2b+3ab^2-b^3}[/tex]

[tex](1+\sqrt{2})^3 =1^3 + 3\cdot 1^2 \cdot\sqrt{2} + 3 \cdot 1 \cdot (\sqrt{2}) ^2 + (\sqrt{2}) ^3 = \boxed{7+5\sqrt{2}}[/tex]

[tex](1-\sqrt{2})^3 =1^3 - 3\cdot 1^2 \cdot\sqrt{2} + 3 \cdot 1 \cdot (\sqrt{2}) ^2 - (\sqrt{2}) ^3 = \boxed{7-5\sqrt{2}}[/tex]

[tex]\therefore (1+\sqrt{2})^3 + (1-\sqrt{2})^3 =7+5\sqrt{2} + 7-5\sqrt{2} = \boxed{14}[/tex]

Answer:

120km/h

600km in 5 hours.

Step-by-step explanation:

1000 meters is equal to 1 kilometer. 1 meter is equal to .001 kilometer.

You can set up an equation like this to solve for the car's rate in kilometers.

[tex]\frac{1 km}{1000 m} = \frac{x km}{35m}[/tex]  or  [tex]\frac{1000 m}{1000 km} = \frac{x m}{35km}[/tex].

Now crossmultiply either fraction to solve for x.

[tex]\frac{1 km}{1000 m} = \frac{x km}{35m}\\\frac{1 km}{1000 m}*35 = \frac{x km}{35m}*35\\\frac{35 km}{1000 m} = xkm[/tex]

The car is going at .035km/sec. Now we need to multiply this to get kilometers per hour. There are 60 seconds in a minute and there are 60 minutes in a hour.

[tex]\frac{35}{1000} * 60 * 60[/tex]

The car travels at 120km per hour.

Since we now know the rate in kilometers per hour. We can multiply the rate by 5 since the question asks how many kilometers the car will travel in 5 hours.

120 * 5 = 600

The car will travel 600km in 5 hours.

Step-by-step explanation:

The dimensions of the rectangle are 4 ft by 5 ft.

Given that the length of a rectangle is 3 ft less than twice the width, and the area of the rectangle is 44 sq.ft. We have to find the dimensions of the rectangle. Let's consider the width of the rectangle as x ft.Length of the rectangle = (2x - 3) ftArea of the rectangle = Length x Width44 = (2x - 3) x x44 = 2x^2 - 3x44 = x (2x - 3)2x^2 - 3x - 44 = 0To solve for x, we will factorize the equation by splitting the middle term.2x^2 - 8x + 5x - 20 = 0Factorize2x(x - 4) + 5(x - 4) = 0(x - 4) (2x + 5) = 0x = 4 ft (since the width of a rectangle can't be negative)or 2x = -5This gives us an invalid value, so x = 4 ftNow that we have the width of the rectangle, we can calculate the length as follows:Length of the rectangle = (2x - 3) ftLength of the rectangle = (2 * 4) - 3Length of the rectangle = 8 - 3Length of the rectangle = 5 ft.
