Answer:
C. the lines will be intersecting but neither parallel nor perpendicular
Step-by-step explanation:
changing the x coeficient means you're changing the gradien/ slope. so it will intersecting in one point of y if the x = 0
y = 2x + 4
y = 2(0) + 4 = 4
y = 3x + 4

14. Twelve more than seven times a number equals the number less six
Answers
Answer:
The number is -3.
Step-by-step explanation:
Set up an equation:
Variable n = number
12 + 7n = n - 6
Assuming the question is solve for n, isolate the variable:
Subtract n from both sides:
12 + 6n = -6
Subtract 12 from both sides:
6n = -18
Divide by 6 on both sides:
n = -3
Check your work:
12 + 7(-3) = -3 - 6
12 - 21 = -3 - 6
-9 = -9
Correct
12+6n=-6
6n=-18
n=-3

Answer:
h=8
Step-by-step explanation:
a²+b²=c²
a=A
b=12
c=13
therefore substitute
A²+(12)²=(13)²
A²=13²-12²
A²=25
A=5
h=3+A
h=3+5
h=8
Answer:
8 ft
Step-by-step explanation:
since it is a right angled triangle and you have 2 side lengths, we use the pythagoras theorem here.
a² + b² = c²
the c² is always your hypotenuse (longest side of the triangle, also opposite to the right angles)
*the b and a doesnt matter which order you put it in*
so; (sub in the numbers to the formula)
a² + 12² = 13²
(rearrange - like terms together)
a² = 13² - 12²
(calculate it)
a² = 25
(simplify it - get rid of the ² on the a)
a = √25
(solve)
a = 5
so, we know that a = 5 and we know that we have an additional 3
5 + 3 = 8

Step-by-step explanation:
n is how many additional hours after the first hour she babysits. She charges $5.75 for each additional hour. So, that would be:
5.75n
But for the first hour, she charges 6.50. So that would be:

In tilton school there are 380 students in key stage 3 240 students in key stage 4 110 students in key stage 5 phoebe is carrying out a survey. she needs a sample of 100 students
Answers
Answer:
52
Step-by-step explanation:
Total Number of students :
Stage 3 : 380
Stage 4 : 240
Stage 5 : 110
Total = (380 + 240 + 110) = 730
Number of samples required = 100
Number of key stage 3 students required :
(Key stage 3 / total) * number of samples
(380 / 730) * 100
= 0.5205479 * 100
= 52.0547
= 52
