Step-by-step explanation:
Answer: y=-6x-7
Step-by-step explanation:
Slope-intercept form is y=mx+b. This means, we want to isolate y.
18x+3y=-21 [subtract both sides by 18x]
3y=-18x-21 [divide both sides by 3]
y=-6x-7
Now, our equation is in slope-intercept form.
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

#SPJ1
Answer:
The total trip will be 4 hours long.
Step-by-step explanation:
The length of the trip decreases by 65/2 miles for every half hour. So in 2 half hours (or 1 hour), Aubree would have traveled the last 65 miles she needed.
Answer:
A
Step-by-step explanation:
The n th term formula for a geometric sequence is
= a
where a is the first term and r the common ratio
here a = - 5 and r = - 10 ÷ - 5 = 2, thus
= - 5( → A
