Answer:

g(1)=7 1/5

Step-by-step explanation:

vertex (-5,0) , y intercept(0,5)

the quadratic equation is in the form of a parabola: y=ax²+bx+c

y=a(x-h)²+k    find a and b and c

5=a(0-(-5))²+0

5=a(5)²+0

5=25a  ⇒ a=5/25 ⇒ a=1/5

-b/2a=h

-b=2ah ⇒=-b=2(1/5)(-5) ⇒ -b=-2⇒ b=2

y=c=5 ( when x=0, y intercept)

y=1/5x² + 2x + 5

g(1)=1/5(1)²+2(1)+5

g(1)=1/5+2+5

g(1)=7 1/5

A quadratic function has a degree of 2, and it is represented as: [tex]y = ax^2 + bx + c[/tex]. The value of g(1) is -7.2

Given that:

[tex](h,k) = (-5,0)[/tex] --- the vertex

[tex](x,y) = (0,-5)[/tex] --- the y-intercept

The quadratic function in vertex form is:

[tex]y = a(x - h)^2 + k[/tex]

Where:

[tex](h,k) = (-5,0)[/tex] --- the vertex

So, we have:

[tex]y = a(x - -5)^2 + 0[/tex]

[tex]y = a(x +5)^2[/tex]

Substitute [tex](x,y) = (0,-5)[/tex] to calculate the value of a

[tex]-5 = a(0 +5)^2[/tex]

[tex]-5 = a(5)^2[/tex]

[tex]-5 = a \times 25[/tex]

Divide both sides by 25

[tex]a = -\frac 15[/tex]

So, the quadratic equation is:

[tex]y = a(x +5)^2[/tex]

[tex]y = -\frac 15(x +5)^2[/tex]

Rewrite as a function

[tex]g(x) = -\frac 15(x +5)^2\\[/tex]

To calculate g(1), we simply substitute 1 for x

[tex]g(1) = -\frac 15(1 +5)^2[/tex]

[tex]g(1) = -\frac 15(6)^2[/tex]

[tex]g(1) = -\frac 15 \times 36[/tex]

[tex]g(1) = -7.2[/tex]

Hence:

The value of g(1) is -7.2

Answer:

(7x+1)=x-5

Step-by-step explanation:

Answer: Answer is in the steps

Step-by-step explanation:

A)  First convert 65 miles to kilometers  

65 miles to kilometers  is 104.607  

Convert 1 hour to minute and that will be 60 minutes because 60 minutes makes and hour.

Now divide the kilometers by the number of minutes

104.607 / 60 = 1.74345  

The speed will be 1.74345 kilometers per minute.

B) Convert 3.5 hours to minutes.

3.5 hours is the same as 210 minutes    

Now multiply it by 1.74345 to determine how many kilometers you have traveled.

1.74345 * 210 = 366.1245

You will travel 366.1245 kilometers in 3.5 hours.

Answer:

4x + 10 > 3x + 14

x > 4

Step-by-step explanation:

Use the given values for length and width in the formula for perimeter of a rectangle.  You will be able to find the perimeter of rectangles A and B.

A = 2(l + w)

A = 2(x + 5 + x)

A = 2(2x + 5)

A = 4x + 10

B = 2(l + w)

B = 2(x + 7 + x/2)

B = 2(3x/2 + 7)

B = 3x + 14

The perimeter of rectangle A is larger than that of rectangle B.

A > B

4x + 10 > 3x + 14

(4x + 10) - 3x > (3x + 14) - 3x

x + 10 > 14

(x + 10) - 10 > 14 - 10

x > 4

Answer:

y=2 16/25

in other words, two and sixteen twenty-fifths

Step-by-step explanation:

y/2-1/5=2-y/3

Move the variables to one side and constants to the other

y/2+y/3=2+1/5

Multiply y/2 by 3/3 and y/3 by 2/2 so that they have a common denominator

3y/6+2y/6=2 1/5

5y/6=11/5

Cross multiply

66=25y

y=66/25

y=2 16/25

Answer:

The slope of the equation y-3=-4(x-5) is -4.

Step-by-step explanation:

This equation is written in point-slope form: y-y₁=m(x-x₁), where "m" is the slope or the equations.  In the equation y-3=-4(x-5), the -4 stands in the "m", or slope, spot, so the sope of this equation is -4.

Slope of the equation is equals to -4.

" Slope is defined as the ratio of the change in y-coordinates to the x-coordinates. It is also known as inclined plane."

General equation of line

y = m x + c                              ____(1)

'm' = slope of the line

'c' = y - intercept

According to the question,

Given equation,

[tex]y-3 = -4(x-5)[/tex]

Open the brackets of the equation we get,

[tex]y-3 = -4x+20[/tex]

Add 3 both the sides of the equation we get,

[tex]y = -4x+23[/tex]                      ______(2)

Compare equation (1) and (2)  to get the slope we have,

Slope 'm' = -4

y-intercept = 23

Hence, slope of the equation is equals to -4.

Step-by-step explanation:

Distribute/ Multiply:

8x - 4 - 3 = 9x - 36

Answer:

-1/6

Step-by-step explanation:

- 1/2 + 3/4 x 4/9 = -1/2 + 3(4) / 4(9) = -1/2 + 12 / 36 = -1/ 2 + 1 / 3 = -3/6 + 2/6 = -1/6

The solution for the given expression [tex]-\frac{1}{2} +(\frac{3}{4} \times \frac{4}{9} )[/tex] after simplifying the expression is [tex]-\frac{1}{6}[/tex].

Given an expression:

[tex]-\frac{1}{2} +(\frac{3}{4} \times \frac{4}{9} )[/tex]

It is required to find the value of the expression after simplifying the expression.

Since there is more than one operation used in this expression, the rule of BODMAS has to be used.

The expression in brackets has to be solved first, which is [tex]\frac{3}{4} \times \frac{4}{9}[/tex].

Here, the numerator of the first fraction and the denominator of the second fraction is 4. So, it can be canceled.

So, this can be simplified as:

[tex]\frac{3}{4} \times \frac{4}{9} =\frac{3}{9}[/tex]

         [tex]=\frac{1}{3}[/tex]

The whole expression thus is [tex]-\frac{1}{2} +\frac{1}{3}[/tex].

Make the denominators equal.

[tex]-\frac{1}{2} +\frac{1}{3} =-\frac{3}{6} +\frac{2}{6}[/tex]

            [tex]=-\frac{1}{6}[/tex]

Hence, the value is [tex]-\frac{1}{6}[/tex].

Answer:

y = - 2x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (1,1) ← 2 points on the line

m = [tex]\frac{1-3}{1-0}[/tex] = - 2

The line crosses the y- axis at (0, 3) ⇒ c = 3
