Answer:
x=23
Step-by-step explanation:
The line 1 has equation 5x + 6y + 30 = 0. Given
that P is the point (3, -1), find
(i) the coordinates of the point where l crosses the
x-axis,
(ii) the coordinates of the point of intersection
of l with the line x = 2,
(iii) the equation of the line passing through P
and having the same gradient as I,
(iv) the equation of the line passing through P
and having a gradient of 0.
w through the points ACO 3).
Answer:
Step-by-step explanation:
i) the x-intercept is when y=0
5x+6(0)+30=0
5x=-30
x=-6
hence the point is (-6,0)
ii)5(2)+6y+30=0
10+6y+30=0
6y=-40
y=-20/3
hence the point of intersection is (2,-20/3)
iii) y+1=-5/6(x-3)
6y+6=-5x+15
6y+5x=9
iv) y+1=0(x-3)
y=-1

Answer:
Which number lies halfway between:
a) 16 and 38 = 28
b) 259 and 361 =310
1004 and 2012?
=1058
The midpoint of all the numbers are given below.
What is the midpoint?A location that is halfway between two other points is considered to be a line segment's midpoint. The distance between the midway and each endpoint is the same.
We have to find the midpoint of numbers.
a) 16 and 38
16 + 38 = 54/2 = 27
b) 259 and 361 = 620/2 = 310
c) 1004 and 2012 = 1508.

According to the properties of inequality, when should the inequality symbol be reversed when solving a two-step inequality in the form below?
a x + b greater-than c
when a is positive
when a is negative
when b is positive
when b is negative
Answer:
B. when a is negativeStep-by-step explanation:
Inequality given:
ax + b > cWhen solving we do steps:
ax > c - bx > (c - b)/aAt the second step both sides divided by a.
When a is positive the inequality symbol remains as is, when a is negative we have to divide both sides by -1 as well. This will reverse the inequality symbol.
Correct answer choice is B.
Answer:
b

If you aren't allowed to use calculators do (1280 - 128pi) but if you are do (877.876140341) Don't forget units in your work and answer.
Step-by-step explanation:
Volume of Rectangular prism = L*W*H = 8*10*16 = 1280in
Volume of Cylinder = pi*r^2*H = 8*pi*r^2
We know that the diameter is 8 (because that's the height of the rectangular prism as stated in the question) and diameter is 2*r thus the radius of the cylinder is 4.
therefore the volume of the cylinder is 8*pi*(4)^2 which is 128pi If you aren't allowed to use calculators do (1280 - 128pi) but if you are do (877.876140341)

Answer:
3
Step-by-step explanation:
Number of craft stick per star = 5
Total number of craft stick had = 19
Total Number of stars that could be made :
Total number of craft stick / number of craft stick per star
= 19 / 5
= 3.8
The maximum Number of stars she could make is the whole number value (discarding the remainder) = 3

f(x)=x2 + 4x -6
f(x) can be written in the form (x + m)?+n.
Find the value of m and the value of n.
Answer:
m = 2 and n = -10
Step-by-step explanation:
The given function is f(x) = x² + 4·x - 6
The form in which f(x) is to be written = (x + m)² + n, which is the standard form of a quadratic equation
We have;
f(x) = x² + 4·x - 6 = x² + 4·x + 4 - 6 - 4
f(x) = x² + 4·x + 4 - 6 - 4 = (x + 2)² - 10
f(x) = (x + 2)² - 10
By comparison with (x + m)² + n, we have;
m = 2, and n = -10

A bicycle tire makes 40 full revolutions while traveling where Scott is standing to where Steve is standing. If a tire has a diameter of 20 inches what is the approximate distance between where Steve is standing?
Answer:
2513.27 inches
Step-by-step explanation:
Given that:
Diameter = 20 inches
Number of revolutions = 40
For a complete revolution :
Distance traveled = Circumference = 2πr
2 * π * 20/2 = 62.831853 inches
Distance per revolution * number of revolutions
62.831853 * 40
= 2513.2741 inches
= 2513.27 inches
