Let x is the smaller integer.
x+12 is the larger integer because two integers differ by 12.
The sum of their square means
x² + (x+12)² = 74
x² + x² + 24x + 144 = 74
2x² + 24x + 70 = 0
2(x² + 12x + 35) = 0
2(x+5)(x+7) = 0
x = -5 or - 7
so we have two answer.
first x = -5 as smaller and 7 as the larger x = -5 + 12 = 7
second x = -7 as smaller and 5 as the larger. x = -7 + 12 = 5
Answer:
$750
Step-by-step explanation:
so $90 is 12% of her weekly income
so you have to do
$90 / 12% = $750
so her income is $750 a week
Answer: option C is the correct answer
Step-by-step explanation:
The y-intercept of the function is the point on the y or vertical axis at which the straight line cuts through it. The value on the y axis is read off as the y-intercept .
The equation of a straight line is modelled using the slope - intercept equation of
y = mx + c
Where m is the slope( change in value of y/ change in value of x.
c = the y-intercept
Looking at the function given,
f(x)=4 – 5x? Where f(x) is the same as y in our slope intercept equation.
Rearranging the function, it becomes
f(x)= – 5x +4
The intercept is 4
Option C is the correct answer.
Answer:
According to most financial experts, it's wise to save at least six months of net living expenses in an emergency fund. So if a family requires $3,000 a month to pay all of its expenses, then it should strive to accumulate $18,000 in an interest bearing emergency savings account.
