Answer:

<h2>Jordan age = 31 years</h2><h2>Anna age = 19 years</h2>

<u>Step-by-step explanation:</u>

let Jordan age be <u>X</u> & Anna age be <u>Y</u>

so,

Jordan is 12 years older than Anna.

x = y + 12 ......... (1)

The sum of their ages is 50.

x + y = 50 ........ (2)

putting value of x from (1) into (2)

x + y = 50

(y + 12) + y = 50

2y + 12 = 50

2y = 50 - 12

2y = 38

y = 38÷2

y = 19

putting value of y in (2)

x + y = 50

x + 19 = 50

x = 50 - 19

x = 31

so,

Jordan age = 31 years

Anna age = 19 years

Can someone help me with my algebra?

SIZIF [17.4K]

Answer:

The top graph

Solutions:

-2

Step-by-step explanation:

The given quadratic function in factored form is

$f(x) = - (x + 2)(x - 2)$

This is a parabola that has x-intercepts at (-2,0) and (2,0)

This parabola opens downward because the leading coefficient is less than 1.

The second function is

$g(x) = 2 |x + 2|$

This is an absolute value function with vertex at (-2,0).

Therefore the graph that shows the solution to f(x)=g(x) is the top graph.

Hence the solution is x=-2,x=0

How do stem leaf charts work

Lyrx [107]

Answer & Explanation:

A stem and leaf plot is used to organize data as they are collected. A stem and leaf plot looks something like a bar graph. Each number in the data is broken down into a stem and a leaf, thus the name. The stem of the number includes all but the last digit.

What is the sum and product to this quadratic equation.<br> x^2+7x+2=0

Pani-rosa [81]

I don't know specifically what the sum and product of an equation is but

factor using quadratic formula

if you have an equation in ax^2+bx+c=0 then you can solve for x using

$x= \frac{-b+ \sqrt{b^2-4ac} }{2a}$ or $x= \frac{-b- \sqrt{b^2-4ac} }{2a}$

so input
a=1
b=7
c=2

$x= \frac{-7+ \sqrt{7^2-4(1)(2)} }{2(1)}$
$x= \frac{-7+ \sqrt{49-8} }{2}$
$x= \frac{-7+ \sqrt{41} }{2}$ =aprox -0.2984378812836

$x= \frac{-7- \sqrt{7^2-4(1)(2)} }{2(1)}$
$x= \frac{-7- \sqrt{49-8} }{2}$
$x= \frac{-7 \sqrt{41} }{2}$ =aprox -6.7015621187165
