Answer:

<h2>x = 9.5</h2>

Step-by-step explanation:

x+(2x+3)+0.3(2x+3)=38.10\qquad\text{use the distributive property for}\ 0.3(2x+3)\\\\x+2x+3+(0.3)(2x)+(0.3)(3)=38.1\\\\x+2x+3+0.6x+0.9=38.1\qquad\text{combine like terms}\\\\(x+2x+0.6x)+(3+0.9)=38.1\\\\3.6x+3.9=38.1\qquad\text{subtract 3.9 from both sides}\\\\3.6x+3.9-3.9=38.1-3.9\\\\3.6x=34.2\qquad\text{divide both sides by 3.6}\\\\\dfrac{3.6x}{3.6}=\dfrac{34.2}{3.6}\\\\x=9.5

Answer:

x = 9.5

Step-by-step explanation:

<u>Step 1:  Distribute</u>

x + (2x + 3) + 0.3(2x + 3) = 38.10

<em>x + 2x + 3 + 0.6x + 0.9 = 38.10</em>

<u>Step 2:  Combine Like Terms</u>

x + 2x + 3 + 0.6x + 0.9 = 38.10

<em>3.6x + 3.9 = 38.10</em>

<u>Step 3:  Subtract 3.9 from both sides</u>

3.6x + 3.9 - 3.9 = 38.10 - 3.9

3.6x / 3.6 = 34.2 / 3.6

<em>x = 9.5</em>

Answer:  x = 9.5

URGENT HELP PLEASE
sammy [17]

Answer:

slope1 : 7,  slope 2 = 3     solution: (2,5)

Step-by-step explanation:

I simplify some steps

pair 1:    x1   0     2

            y1   -9     5 ........ -9, y1 intercept

pair 2:   x2   0    2

             y2  -1    5   ........ -1, y2 interept

2 pairs meet at (2,5)

y=7x-9 ......A

y=3x-1  ......B

A-B    0=4x-8

4x=8

x=2

y=5

slope 1=( y2-y1) / (x2-x1) = (5- -9)/(2-0) = 14/2 =7

slope 2 = (5 - -1) / (2 - 0) = 6/2 = 3

7/7q+21= x /5q^2-45 then x=?​
anzhelika [568]

Answer:

x = 5q - 15

Step-by-step explanation:

\frac{7}{7q+21}=\frac{x}{5q^{2}-45}\\\\\frac{7}{7(q+3)}=\frac{x}{5 (q^{2} -9)}\\\\frac{1}{q+3}=\frac{x}{5*(q^{2}-3^{2})}\\\\\frac{1}{q+3}=\frac{x}{5(q+3)(q-3)}\\\\\frac{1}{q+3}*5*(q+3)(q-3)=x\\\\5(q-3)=x\\\\x= 5q-15

How do you get 25 for the order of operations
mojhsa [17]
PEMDAS Solve the parentheses first so 9+4=13. Then do the division so 6/6=1. Now the equation is 37- 13+ 1. Then work left to right. 37-13= 24 then 24+1=25.

How to find domain and range of a parabola?
german
The domain is the value of x, the range is the value of y.
A parabola opens infinitely to the right and left, so x can be any number, the domain is all real numbers
Vertically, however, a parabola opens only one way, either upward or downward. when it opens upward from a a certain level, say, the lower point (the vertex) has a y coordinate of 2, we say the range is all real numbers larger than or equal to 2, or y≥2. When it opens downward, we say the range is all real numbers smaller or equal to 2, y≤2
