Answer:
(6, 0 )
Step-by-step explanation:
to find where the line crosses the x- axis, let y = 0 in the equation and solve for x
0 = x - 6 ( add 6 to both sides )
6 = x
the line crosses the x- axis at (6, 0 )
Instead of y write 0:
0=x-6
Now solve for x :0=x-6
Add 6 on both sides6=x or x=6
We know the x coordinate of the point that intersects the x axis; the y coordinate is always 0.
Coordinates of the point ↓(6, 0)
which expressions are equivalent to 4^-2*7^-2
Answer:
[tex]\textsf{B)}\quad \dfrac{1}{28^2}[/tex]
[tex]\textsf{C)} \quad \dfrac{7^{-2}}{4^2}[/tex]
Step-by-step explanation:
[tex]4^{-2} \cdot 7^{-2}[/tex]
[tex]\textsf{Apply exponent rule} \quad (a^b \cdot c^b)=(ac)^b:[/tex]
[tex]\implies (4 \cdot 7)^{-2}[/tex]
[tex]\implies (28)^{-2}[/tex]
[tex]\textsf{Apply exponent rule} \quad a^{-n}=\dfrac{1}{a^n}:[/tex]
[tex]\implies \dfrac{1}{28^2}[/tex]
-------------------------------------------------------------------------------------------
Also,
[tex]4^{-2} \cdot 7^{-2}[/tex]
[tex]\textsf{Apply exponent rule} \quad a^{-n}=\dfrac{1}{a^n}:[/tex]
[tex]\implies \dfrac{7^{-2}}{4^2}[/tex]
[tex]\\ \rm\Rrightarrow 4^{-2}7^{-2}[/tex]
a^{-n}=1/a^n[tex]\\ \rm\Rrightarrow \dfrac{1}{4^2.7^2}[/tex]
a^n×b^n=(ab)^n[tex]\\ \rm\Rrightarrow \dfrac{1}{(4.7)^2}[/tex]
[tex]\\ \rm\Rrightarrow \dfrac{1}{28^2}[/tex]
If we break only 4

7 in
A. 56.13 in2
B. 35.13 in2
C. 70.26 in2
D. 49,26 in2
Answer:
C 70.26 in2
Step-by-step explanation:
6 = D
R = D/2
R = 3
A = 3.14 x 3 x 3
A = 3.14 x 9
A = 28.26
The area of the triangle is
A = 6 x 7
A = 42
So
42 + 28.26
70.26 in2

Each day, a salesperson earns $25 plus 5% of their total sales for the day. The salesperson's goal is to earn more than $50 on Thursday. Which statements are true? Select all that apply.
The true statement about the inequality is that Total sales per day is greater than $250
How to write and solve inequality equation?Total sales per day = xAmount earned per day = 25 + 5% of x= 25 + 0.05x
Thursday = 4th day of the weekThe inequality:
4(25 + 0.05x) > 50
100 + 0.2x > 50
100 - 50 > 0.2x
50 > 0.2x
x > 50/0.2
x > $250

Joe, a plumber, charges $45 per hour plus
$100 for making an in-home visit. Write
and solve an equation to find out how
many hours of plumbing work are needed
Answer: The answer is five
Step-by-step explanation:
Set y = z
50x + 75 = 65x
Subtract 50x from both sides
50x (-50x) + 75 = 65x (-50x)
75 = 15x
Divide both sides by 15
75 (/15) = 15x (/15)
5 = x
And there we have it, x = 5! So it takes 5 hours of work for each to cost the same.
Answer: (Y - 100)/ 45 =No of hours
where y is the full payment
Step-by-step explanation:
Charges per hour plus visit is 45+100 where 100 Is fixed
2hr is (45 × 2) +100
Payment y for Xhrs= 45X + 100
Y =45X + 100
Y -100 =45X
Y -100/45 = X

500ml of milk for 60p
4 litres for £3.20
Which bottle is better value for money?
Answer:
4 liters for £3.20
Step-by-step explanation:
we want to maximize quantity for each unit of money spent. if we use mL and p, we want to maximize mL/p
500 mL = 60 p
divide both sides by 60p to get a mL/p value
500 mL/60 p = 50/6 p ≈ 8.3 mL per pence
4 L = £3.20
note:
1000 mL = 1L
divide both sides by 1 L/ 1000 mL
1000 mL / 1 L = 1
1 L / 1000 mL = 1
100 p = £1
divide both sides by 100p / £1
100p / £1 = 1 = £1 / 100p
convert everything to the same units (mL and p) to accurately compare
4 L = £3.20
4L = 4L * 1 = 4L * 1000 mL / 1 L = 4000 mL. Note that we have two options to choose from -- 1000 mL / 1 L and 1 L / 1000 mL. We choose the first one here because we want the 4L to cancel out with the 1 L
£3.20 = £3.20 * 1 = £3.20 * 100p / £1 = 320 p. note we put the £1 on the bottom so the euros cancel out.
thus,
4 L = £3.20
= 4000 mL = 320p
divide both sides by 320p to get a mL / p value
4000 mL / 320 p = 12.5 mL/p
8.3 mL per pence in the first one
12.5 mL per pence in the second one
the second one has a higher mL per pence, so that is a better value

1. The measure of 2G is 82º. What is the

Answer:

Step-by-step explanation:
Since a supplementary angle is 2 angles which equal 180 degrees we would have this angle and 1 more angle that add up to 180:

subtract 82 from both sides

The answer to this expression is [tex]\frac{13x-6}{6}[/tex], or [tex]\frac{13x}{6} - 1[/tex].
Step-by-step explanation:
The given problem is [tex]\displaystyle \frac{2x}{3}+\frac{(3)x-2}{2}[/tex] .
Let's start by finding common denominators for the fractions so that we can add them. The simplest common denominator is 6; we multiply [tex]\frac{2x}{3}[/tex] by [tex]\frac{2}{2}[/tex] and [tex]\frac{3x-2}{2}[/tex] by [tex]\frac{3}{3}[/tex].
[tex]\displaystyle \frac{2x}{3} \times \frac{2}{2} =\frac{4x}{6}[/tex][tex]\displaystyle \frac{3x-2}{2} \times \frac{3}{3} = \frac{3(3x-2)}{6} = \frac{9x-6}{6}[/tex]Now, since the fractions have common denominators, we can add them together.
[tex]\displaystyle \frac{4x}{6} + \frac{9x-6}{6} = \frac{13x-6}{6}[/tex]The answer to this expression is [tex]\frac{13x-6}{6}[/tex], or [tex]\frac{13x}{6} - 1[/tex].
