Answer:
(1, -5)
Step-by-step explanation:
Here, it is easy to check the offered choices. We find the first one works, so our check is short.
For (x, y) = (1, -5)
3·1 +10·(-5) = 3 -50 = -47 . . . yes
5·1 -7·(-5) = 5 +35 = 40 . . . yes
__
Both of the intercepts in the first equation are negative, so the line will form a triangle with the axes in the 3rd quadrant. The intercepts for the second equation are negative for y and positive for x, so the line forms a triangle with the axes in the 4th quadrant. The y-intercept for the first equation is -4.7; for the second equation, it is -40/7 = -5 5/7. This means the lines must cross in the 4th quadrant.
The only offered point in the 4th quadrant is (1, -5).

Answer:
12
Step-by-step explanation:
Well, 12/12=1, which I guess is the smallest number we can get, and 12 is divisible by 2 too.

Given:
A rectangle has a length 5 meters more than five times the width.
The area of the rectangle is less than 100 meters squared.
To find:
The expression or inequality that represents all possible widths of the rectangle.
Solution:
Let x be the width of the rectangle.
Length of the rectangle is 5 meters more than five times the width.
[tex]length=5x+5[/tex]
Area of rectangle is
[tex]Area=length \times width[/tex]
[tex]Area=(5x+5) \times x[/tex]
[tex]Area=5x^2+5x[/tex]
The area of the rectangle is less than 100 meters squared.
[tex]5x^2+5x<100[/tex]
[tex]5x^2+5x-100<0[/tex]
Divide both sides by 5.
[tex]x^2+x-20<0[/tex]
[tex]x^2+5x-4x-20<0[/tex]
[tex]x(x+5)-4(x+5)<0[/tex]
[tex](x+5)(x-4)<0[/tex]
It is true if one factor is negative and other is positive. So,
[tex]x-4<0\Rightarrow x<4[/tex] ...(i)
[tex]x+5>0\Rightarrow x>-5[/tex] ...(ii)
Using (i) and (ii), we get
[tex]-5<x<4[/tex]
Therefore, the required expression or inequality for possible
widths of the rectangle is [tex]-5<x<4[/tex].

if it's helpful please tell me
Answer: The least common multiple is 65700
Step-by-step explanation:
To begin, find the prime factors of the given numbers, (and you find they have very little in common.)
9=3×3 25=5×5 36=2×2×3×3 73= 73×1 (73 is a prime number)
Only the 3's of 36 overlap with the 3's of 9
To find the LCM you must multiply all the prime factors that don't overlap:
3×3×5×5×2×2×73
If the 73 is changed to 72, the LCM is a somewhat lower number: 1800.
To test these LCM's try dividing by any of the factors or numbers given.
If the quotient is not a whole number, the LCM doesn't include that factor.

A. The Clear-Picture Cable Company charges different rates for ordering different levels of cable service. Clear-Picture Cable Company charges $24.95 a month for basic cable services plus $6.95 a month for each additional premium channel. If Stacey's monthly bill is $45.80, how many premium channels is she receiving? Write and solve and equation to answer the question. Show all work.
B. Dan signed a contract for 12 months of basic cable service with 2 premium channels each month. Dan budgeted $400 for this year's cable expenses. EXPLAIN whether Dan budgeted enough money to cover the yearly cost for his cable contract.
(please answer with all work and a full explanation for B. THANKS SO MUCH!!)
Answer:
A. 3 premium channels
B. No, he did not
Step-by-step explanation:
1a. make an equation that shows the price Stacey has to pay each month. x is how many premium channels she's paying for.
24.95 + 6.95x = 45.8
2a. subtract 24.95 from both sides.
6.95x = 20.85
3a. divide both sides by 6.95.
x = 3
1b. make an expression to show the price of Dan's contract. (keep in mind, he has to pay for 2 premium channels for 12 months, so you would have to pay for the premium channels 24 times!)
24.95(12) + 6.95(24)
2b. multiply.
299.4 + 166.8
3b. add.
$466.20
Dan would have to pay $466.20, so no, he did not budget enough money.
Write an equation in point-slope form of the line that passes through (2,7) and has the slope m=4
Answer: y-7=4(x-2)
Step-by-step explanation:
Point-slope form is y-y₁=m(x-x₁). Since we are given the point and slope, we can directly plug them in.
y-7=4(x-2)
Now, we know that y-7=4(x-2) is the equation.

Answer:
b=−ax+4a+3x
a= b−3x −x+4
Step-by-step explanation:
The values of a and b make the solution of the equation x = -5 are 1 and -6
How to determine the values of a and b?The equation is given as:
a(4-x) = -3x+b
When x = -5, we have:
a(4+5) = -3(-5)+b
Evaluate the products
9a = 15 + b
Set a = 1
9(1) = 15 + b
Make b the subject
b = 9 - 15
b = -6
Hence, the values of a and b make the solution of the equation x = -5 are 1 and -6
