Answer:
one
Step-by-step explanation:
I think, there were 4 lines and the two lines are reaching each other
x^2-9x-6=0
Use the quadratic formula to get (9+sqrt(105))/2 or (9-sqrt(105))/2
Answer:
Parallel
Step-by-step explanation:
In the slope-intercept form (y=mx +c), the coefficient of x tells us the slope of the line.
2x +8y= 56
Let's rewrite this equation into the slope-intercept form.
8y= -2x +56
Dividing both sides by 8:
Slope= -¼
y= -¼x -5
Slope= -¼
Since both lines have the same slope, they are parallel to each other.
Answer:
Sale price is $2.58.
Paid with tax is $2.73
Step-by-step explanation:
If the make-up is originally $4.30 and you receive a 40% discount. This means you'll pay 60% of the price since 100-40=60.
To find this price, 60% as 0.6 is multplied with the price. 0.6*4.30 = $2.58
This is the sale price.
When you pay you will pay 6% tax or 0.06 of the price. Find this by multiplying $2.58 by 1.06.
2.58(1.06) = $2.73
Answer:
168
Step-by-step explanation:
Sum the parts of the ratio, 6 + 7 = 13 parts
Divide the total number of students by 13 to find the value of one part of the ratio.
364 ÷ 13 = 28 ← value of 1 part of the ratio, thus
number of girls = 6 × 28 = 168
