Answer:

below

Step-by-step explanation:

When are adding a negative number, that means that you just subtracting a positive value.

-3 + (-5) -> -3 - 5

On a number line you would to put finger at the point -3 and move to the left 5 spaces since we are subtracting.

Best of Luck!

Answer:

[tex]\huge\boxed{\sf f(4x + 5) = 16x\² + 40x + 25}[/tex]

Step-by-step explanation:

Given that:

f(x) = x²

Put x = 4x + 5

f(4x + 5) = (4x + 5)²

f(4x + 5) = (4x + 5)(4x + 5)

f(4x + 5) = 4x(4x + 5) + 5(4x + 5)

f(4x + 5) = 16x² + 20x + 20x + 25

f(4x + 5) = 16x² + 40x + 25

Answer:

A triangular prism

Explanation:

The 2 triangles will be the 2 bases and the 3 rectangles will be the 3 sides.

Answer:

Step-by-step explanation:

The answer is actually

Let:

S=1+2+3+4+5+6+7+8+9+n

We know the answer to the following infinite sum:

S2=1-1+1-1+1-1+1-1+1-1+1-1+1-....= - 1/2

We can therefore solve for this sum:

S3=1-2+3-4+5-6+7-8+9-....

We add them:

S3=      1-2+3-4+5-6+7-8...

S3=       +1-2+3-4+5-6+7-8...

        ________________

2S3=    1-1+1-1+1-1+1-1+1-....

Therefore:

2S3=S2=

Answer:

125/2

Step-by-step explanation:

62 * 2 = 124

124 1/2 = 124 + 1 = 125/2

Answer:125/2

Step-by-step explanation:

Answer:

When we talk about Intercept... We refer to the place where the line touches or Crosses a Mentioned axis.

In this question... We needed the y - Intercept

Know This: At the intercept of a mentioned axis...The other axis is zero at that point.

In other words... If we're asked for intercept at x-axis ... The y value at that point is zero and Vice Versa

So To find the y Intercept... the x value at this point is zero(0).

With this in Mind...

substitute x = 0 into the quadratic eqn

f(x) = 0² +8(0) - 13

f(x) = -13

This is Our Y Intercept .

To get the x intercept(if asked)

substitute y = 0 and solve

0 = x² + 8x - 13

This is a quadratic equation

Solving this would get you two value and those values would be your x intercept.

I hope it helps.

Have a great day.

Answer:

  1/125

Step-by-step explanation:

The map scale is usually shown as the ratio of the map distance to real-world distance. Here, that is ...

  16 cm : 20 m = 16 cm : 2000 cm = 16 : 2000 = 1 : 125

The map scale is 1/125.

Answer:

vertex = (- 3, 7 )

Step-by-step explanation:

The equation of a parabola in vertex form is

f(x) = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

f(x) = (x - 3)² + 7 ← is in vertex form

with vertex = (3, 7 )

Answer:

m = -3

Step-by-step explanation:

15 - (4m - 5) = 32            (Given)

15 - 4m + 5 = 32             (Distributed)

20 - 4m = 32                  (Added like terms)

20 - 4m - 20 = 32 - 20  (Subtract 20 on both sides)

-4m = 12                         (Simplify)

-4m/-4 = 12/-4                (Divide -4 on both sides)

m = -3                             (Simplify)

Answer:

-8.75

Step-by-step explanation:

Rational: a number that can be expressed as an integer or the quotient of an integer divided by a nonzero integer.

A rational number is a number that can be expressed as a fraction with an integer numerator and a positive integer denominator. Two different fractions may correspond to the same rational number. 1/2 = 2/4. Every whole number is a rational number. These can be written as N/1 = N, so they are rational numbers.

Using formula:

[tex]\to \bold{rational\ value =\frac{a+b}{2}}[/tex]

Given:

a=-8

b=-9

Calculating the rational number:

[tex]\to \bold{rational\ number=\frac{-8+(-9)}{2}}[/tex]

                                   [tex]\bold{=\frac{-8-9}{2}}\\\\ \bold{=\frac{-17}{2}}\\\\ \bold{=- 8.5}\\\\[/tex]
