Answer:
(4, 6 )
Step-by-step explanation:
Given the 2 equations
3x + 4y = 36 → (1)
y = - [tex]\frac{1}{2}[/tex] x + 8 → (2)
Substitute y = - [tex]\frac{1}{2}[/tex] x + 8 into (2)
3x + 4(- [tex]\frac{1}{2}[/tex] x + 8) = 36 ← distribute and simplify left side
3x - 2x + 32 = 36
x + 32 = 36 ( subtract 32 from both sides )
x = 4
Substitute x = 4 into (2) for corresponding value of y
y = - [tex]\frac{1}{2}[/tex] × 4 + 8 = - 2 + 8 = 6
solution is (4, 6 )

Which is the sum of the first 6 terms of the geometric series?
7+21 +63
Answer:
2,548
Step-by-step explanation:
First, we have to find out the rule. The rule is multiply the previous number by 3 to get the next number.
7x3=21
21x3=63
So, we would continue this pattern until we have the first 6 numbers which are 189, 567, and 1701.
The questions is asking for the SUM of the 6 numbers so you would add the those numbers and do this equation:
7+21+63+189+567+1701= 2548

what is the multiplication inverse or reciprocal of each number?
Answer:
4
9/8
Step-by-step explanation:
Given the fraction a/b, the reciprocal is expressed as 1/(a/b) = b/a
For 1/4;
1/4
= 1÷1/4
= 1 * 4/1
= 4
Hence the reciprocal is 4
b) 8/9
= 1 ÷ 8/9
= 1 * 9/8
= 9/8
Hence the reciprocal of 8/9 is 9/8
how many solutions does the equation have y=1/2x-7 y=6x+2
Answer:
One solution, x=-18/11.
Step-by-step explanation:
y=1/2x-7
y=6x+2
---------------
1/2x-7=6x+2
1/2x-7-6x=2
1/2x-6x=2+7
1/2x-12/2x=9
-11/2x=9
x=9/(-11/2)
x=(9/1)(-2/11)
x=-18/11
The student council at Oxford High School is making T-shirts to sell for a fundraiser, at a price of $12 apiece. The costs, meanwhile, are $10 per shirt, plus a setup fee of $130.

Answer:
Number of shirts to breakeven = 65 shirtsCost of breakeven shirts = $650Step-by-step explanation:
First find the profit they will make from each shirt:
= Selling price - Cost price
= 12 - 10
= $2
They need to cover the cost of setting up which is $130. The number of shirts to sell given a profit of $2 from each shirt is:
= 130 / 2
=65 shirts
Cost of selling 65 shirts:
= 65 * 10 per shirt
= $650

In the diagram of circle M shown, the measure of major arc PRQ=268 . Which of the following
is the measure of angle PRQ ?
Step-by-step explanation:
The Answer is 46
The measure of Arc PRQ is 268. Another part of the arc is PQ. PRQ+PQ forms a full circle In which a circle has 360 degrees. Using that
[tex]268 + x = 360[/tex]
[tex]x = 92[/tex]
Since we are asked to the measure of PRQ and it is inscribed in arc PQ. It is half of PQ so the answer is
[tex]92 \div 2[/tex]
which is 46.

The ratio of the length to the width of the rectangle is 10:6. Of the perimeter of the rectangle is 160 meters, find the measure of the width. Show your work
Answer:
60 meters, see explanation.
Step-by-step explanation:
We know that the ratio of length : width is 10 : 6. So for every 10 meters of length, we also have 6 meters of width. This problem is much easier since we are given the P = 160 meters.
You can see that if we multiply the ratio by ten, we get 100 : 60, where 100 + 60 = 160 total meters. From here, it is clear that the width would be 60 meters.
ayo so like i'm doing logarithms and i need help how do you solve 3(5)^x=192 for the variable thanks
Answer:
Exact Form:
x = ln ( 64 )/ ln ( 5 )
Decimal Form:
x = 2.58405934 …
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
Step-by-step explanation:
Start by dividing both sides by 3
5^x = 192/3
5^x = 64
Now take the log of both sides
log(5^x) = log(64)
Bring down the power
x log(5) = log(64)
Find the logs
x * 0.69897 = 1.8062
Divide
x = 1.8062 / 0.69897
x = 2.5841

f(x)=2x^2+9
Find f(-5)
Answer:
59
Step-by-step explanation:
Given
f(x) = 2x² + 9
f ( -5) = 2 * ( -5)² + 9
= 25 * 2 + 9
= 50 + 9
= 59
════════ ∘◦❁◦∘ ════════
Answer = 59════════════════════
Knownf(x) = 2x² + 9
════════════════════
Questionf(-5) = ?
════════════════════
Way to do#as you the x inside the (x) changed into (-5) it means that you need to change the x into -5.
f(-5) = 2(-5)² + 9
= 2 × 25 + 9
= 50 + 9 = 59
#So f(-5) = 59

Answer:
Interest= Rs. 10
Step-by-step explanation:
Interest of Rs.100 on 10 p.c.p.a is 10% of 100
i.e., 100*10/100 = 10
Thus we have 10 as the interest

Part B:
I drew a table and just focused on column two. I looked at how many people don't like phone or pc and I found that 10 is how many people like phone and not pc, 30 is people who dont like phone or pc, together its 40, so you need to find what the percentage 30 is of 40, or 3/4, I used a calculator and converted it into a percentage and I got 75%
Mark reduce the size of a photo to a height of 4 inches. What is the new width if it was originally 16 inches tall and 8 inches wide?
Answer:
Step-by-step explanation:
new height is ¼ of original height
new width = ¼×8 = 2 inches
Answer:
2 inches
Step-by-step explanation:
To find the new width, find the scale factor that was used to reduce the photo.
Since 16 divided by 4 is 4, 4 is the scale factor.
To find the new width, divide 8 by 4:
8/4
= 2
So, the new width is 2 inches
