The value of x is 35
<h3>What are algebraic expressions?</h3>
Algebraic expressions are expressions consisting of variables, terms, constants and factors.
They are also made up of arithmetic operations such as addition, subtraction, multiplication, division, etc.
We have that;
5(x+20)= 7x+30
expand the bracket
5x + 100 = 7x + 30
collect like terms
5x -7x = 30 - 100
add like terms
- 2x = -70
Make 'x' the subject
x = -70/ -2
x = 35
Thus, the value of x is 35

In order to answer this question, you need to know what should be in the x axis and what should be in the y axis.
As for this one, you have given the information of the table:<span>
Park patrons Number of dogs
7 4
6 2
9 7
8 6
5 3
7 7
3 1
4 3
The value in the x axis should be the </span>Park patrons
The value in the y axis should be the Number of dogs
<span>1st term:: a/r = (-1/5)/(2) = -1/10
2nd term:: a = -1/5 = -2/10
3rd term:: a*r = (-2/10)(2) = -4/10</span>
+ is bigger and - is smaller 16+1=17 and 18-1=17
Answer:
the y intercept is 4
it represents that when it is 0 hours after sunrise the temperature is 4 degrees celcius
the slope is 4
it represents that every hour of sunrise the temperature increases by 4.
y = 4x + 4
