<em>Answer:</em>
<em>x=7</em>
<em>Step-by-step explanation:</em>
<em>6x+8+7x-9=90</em>
<em>13x+8-9=90</em>
<em>13x-1=90</em>
<em>add 1 to both sides</em>
<em>= 13x=91</em>
<em>divide both sides by 13</em>
<em>= x=7</em>
Answer:
arithmetic
Step-by-step explanation:
This is an arithmetic sequence since there is a common difference between each term. In this case, adding 2 to the previous term in the sequence gives the next term. In other words, an=a1+d(n−1) a n = a 1 + d ( n - 1 ) .
Answer:
y = x + 8
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = , then
y = x + c ← is the partial equation
to find c substitute (- 4, 5 ) into the partial equation
5 = - 3 + c ⇒ c = 5 + 3 = 8
y = x + 8 ← equation of line
