In solving quadratic equation, if the constant term is missing what is the best method to
use?

Answer:

f(-2) = -1

Step-by-step explanation:

-2 is x, so replace x as -2 into the equation

f (-2) = 2(-2) + 3

f (-2) = -4 + 3

f (-2) = -1

A collection of all points in the plane of the form (x, f(x)) is the graph of a function f. The graph of f is defined as the graph of the equation y = f(x).

[tex]\to f (x) = 2x + 3[/tex]

[tex]\to f(-2) =?[/tex]

Putting the value "-2 " into the above given method:

⇒  f(-2) = 2(-2) + 3

⇒  f(-2) = -4 + 3

⇒  f(-2) = -1

Step-by-step explanation:

Answer:

10.1980390272

Step-by-step explanation:

Pythagorean Theorem

Hypotenuse = 15²

Leg = 11²

15² - 11² is 10.1980390272

Answer:

3.24 feet

Step-by-step explanation:

A 17 -ft ladder leans against a building so that the angle between the ground and the ladder is 79 . Find the distance between the building and the ladder

We solve the above question using the Trigonometric function of Cosine

cos x = Adjacent/Hypotenuse

Adjacent = x feet

Hypotenuse = 17 ft

The angle = 79°

Hence,

cos 79 = x/17

Cross Multiply

x = cos 79 × 17

x = 3.2437529214.feet

Approximately = 3.24 feet

Therefore, the distance between the ladder and the building = 3.24 feet

Answer:

(-1,-1)

Step-by-step explanation:

Midpoint equation: [tex](\frac{x_2+x_1}{2}, \frac{y_2+y_1}{2})[/tex]

= [tex](\frac{-5/2+1/2}{2},\frac{-1/2-3/2}{2} )[/tex]

= [tex](\frac{-2}{2},\frac{-2}{2})[/tex]

=(-1,-1)

Answer:

25

Step-by-step explanation:

The perimeter of triangle is equal to the sum of all sides of triangle

then:

5y + (x+8) + (x+3) = 60

5y + 2x +11 = 60

5y +2x = 49  ..............................................................(1)

the hypotenuse - shorter leg = 10

hint (  shorter leg ) = x+3

then

5y - (x + 3 ) = 10

5y - x - 3 = 10

5y - x = 13               .................................................... (2)

from 1 and 2

5y +2x = 49  .................................................................. (3)

5y - x = 13 (multiply both sides by 2 )

10y - 2x = 26 ..................................................................(4)

by sum 3 and 4

15y = 75

then y = 75/15 = 5

then hypotenuse = 5y = 5 x 5 = 25

Step-by-step explanation:

Answer: A, B, and C.

Step-by-step explanation: The answers you have selected in the picture are correct.

These are the actual claims made regarding the line:

The x-intercept is at - 8 because y = 0 when x = -8.

The line is growing and has a positive slope.

As soon as x = 0 and y = 4, the y-intercept is at 4.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

The true statements about the line are,

The x-intercept is at - 8, as when x = - 8 y = 0.

The line has a positive slope as it is increasing.

The y-intercept is at 4 as when x = 0 y = 4.

Answer:

8 13/28 or as a decimal: 8.46

Step-by-step explanation:

Rewrite the sum:

(4+3)+(5/7+3/4)

Add the numbers 4+3:

7+(5/7+3/4)

Add the fractions:

7+41/28

Convert the improper fraction into a mixed number:

7 + 1 13/28

Write the mixed number as a sum of the whole number and the fractional part:

7+1+13/28

Add the numbers 7+1 and then there is your answer!

8 13/28

If your paper, quiz, homework, etc says decimal form or alternative form then the decimal form is 8.46 and the alternate form is 237/26. But 8 13/28 cannot be reduced any lower.

Answer:

  slope: 9/5

  graph: C

Step-by-step explanation:

In a proportional relationship, the slope is the ratio of y to x. Here, that is ...

  slope = y/x = 9/5

__

The graph of a proportional relationship goes through the origin. (eliminates graph B)

For this relationship, y is greater than x. (eliminates graph A)

The appropriate graph for y = 9/5x is graph C.
