Find the solution(s) of the system of equations.
y = –x2 + 2
y = x2 + 4x + 4

Answer:

15.8 or 15 4/5

Step-by-step explanation:

If you are going from a larger unit to a smaller unit, you multiply by successively. If you are going from a smaller unit to a larger unit, you divide by successively. The factor label method can also be applied to conversions within the metric system.

When you are converting from a larger unit to a smaller unit, you will always divide.

When you are converting from a larger unit to a smaller unit, you will always divide. This is because as you move from a larger unit to a smaller unit, you are breaking the quantity down into more individual parts, hence the need for division.

For instance, to convert 5 m to centimeters;

5 meters x (100 centimeters / 1 meter) = 500 centimeters

As you can see, we divided 5 meters by 100 (the number of centimeters in one meter) to obtain the equivalent length in centimeters, which is 500 centimeters.

Answer:

3

Step-by-step explanation:

To evaluate |3b - 4a| substitute a = -3 and b = -5 in the given expression.

|3(-5) - 4(-3)| , multiply

|-15 +12| , add

|-3| , take the -3 out of the absolute value

3

Hey there!

|3b - 4a|

= |3(-5) - 4(-3)|

= |-15 - (-12)|

= |-15 + 12|

= |-3|

= |3|

= 3

Therefore, your answer is: 3

Answer:

A reflection over the x-axis

Step-by-step explanation:

      If you were to put a mirror up to the x-axis and look at one of the shapes, you would "see the" other so we can conclude this is a reflection over the x-axis.

In other words, you could "fold" the graph in half over the x-axis and the two figures would line up.

Answer:

A household equivalence scale allows for transforming the income in an n-member household into an equivalent one-adult-member household. This is necessary for well-being comparisons across households with different number of members.

An equivalence scale is a measure of the cost of living of a household of a given size and demographic composition, relative to the cost of living of a reference house- hold (usually a single adult), when both households attain the same level of utility or standard of living.

The equivalence scale used in the OECD Income Distribution Database divides household income by the square root of the household size. This implies that, for instance, a household of four persons has needs twice as large as one composed of a single person.

Answer:

Equation: y = -3x -2

Graph: Attached below ↓↓↓↓↓

Step-by-step explanation:

The equation is y = -3x + b

We need B at this point.

Since we have a point given to us,( -2, 4)we can input the x and y

Solve:

4 = -3(-2) + b

4 = 6 + b

b = -2

So the equation we have is y = -3x -2

Let's graph the line.

We go 2 units below the x-axis, because the y-intercept is -2, and the slope is -3, so we go down 3 units, and to the right 1.

Answer:

4/5

Step-by-step explanation:

the equation for the slope of a line is

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

we can find the two points (-2,0) and (3,4) on the graph

plugging the points into the equation, we get (4-0)/(3-(-2)

= 4/5

Answer:

(4, 11 ) ; (- 4, 27 )

Step-by-step explanation:

Given

f(x) = x² - 2x + 3 → (1)

f(x) = - 2x + 19 → (2)

Substitute f(x) = x² - 2x + 3 into (2)

x² - 2x + 3 = - 2x + 19 ( add 2x to both sides )

x² + 3 = 19 ( subtract 3 from both sides )

x² = 16 ( take square root of both sides )

x = ± [tex]\sqrt{16}[/tex] = ± 4

Substitute these values into (2) for corresponding values of y

x = 4 : y = - 2(4) + 19 = - 8 + 19 = 11 ⇒ (4, 11 )

x = - 4 : y = - 2(- 4) + 19 = 8 + 19 = 27 ⇒ (- 4, 27 )

Answer: yes

Step-by-step explanation:

x is 5, or 5 points to the right. y is 2, or 2 points up. This correlates with the graph so it is correct.

Answer:

Step-by-step explanation:

there are 2 ways to graph equations. I'll teach u the faster way.

step 1) graph the y-intercept.

so the slop-intercept form of a line is y=mx+b. b represents the y-intercept and m represents the slope. u need two points to graph a line, the first point will be the y intercept. in this case, the y-intercept is -5. so this is what you should do: (the underlined star represents a point. also, the underlined star is on point -5.)

                     | y

                     |

                     |

                     |

------------------------------------------------------------x

                     |

                     |

                     |

                     |

                    *

                     |

step 2) graph the second point using the slope.

slope equals rise over run. (m=rise/run.) in this case, the slope is 5/1. To graph the second point, u should RISE up by 5 and RUN to the right by one:  (the underlined star is on point 1.)

                     | y

                     |

                     |

                     |

-----------------------*-------------------------------------x

                     |

                     |

                     |

                     |

                    *

                     |

now draw a line through those two points.
