I'll do the first three problems to get you started
=====================================================
Problem 40
Plug in x = 0 to find the y intercept
x+y = 5
0+y = 5
y = 5 is the y intercept
Plug in y = 0 to find the x intercept
x+y = 5
x+0 = 5
x = 5 is the x intercept
------------
Answer: The x intercept is 5. The y intercept is 5.=====================================================
Problem 41
Use the same idea here as well
Plug in x = 0 to get
x-y = 5
0-y = 5
-y = 5
y = -5 is the y intercept
Now plug in y = 0 to solve for x
x-y = 5
x-0 = 5
x = 5 is the x intercept
------------
Answer: The x intercept is 5. The y intercept is -5.=====================================================
Problem 42
Plug in x = 0 and solve for y
3x+4y = 12
3(0)+4y = 12
0+4y = 12
4y = 12
y = 12/4
y = 3 is the y intercept
Plug in y = 0 and solve for x
3x+4y = 12
3x+4(0) = 12
3x+0 = 12
3x = 12
x = 12/3
x = 4 is the x intercept
------------
Answer: The x intercept is 4. The y intercept is 3.Marco earned $360 helping his grandfather at his business,He spends 1/4 of his earnings on a gift for his mother and put 2/3 of the rest into a savings account.How much does he have left over for fun?
Answer:
$90
Step-by-step explanation:
$360 is the total
1/4 was spent on the gift
so 360 times 1/4 is 90
360-90=270
we then do the same with this
270 times 2/3 equals 180
270-180=90
$90 left for fun
Hope this helps :-)
If K= {(x, y) l x-y=5}, is Set K a function?
We can solve x-y = 5 for y to get y = x-5. This is a linear function. It graphs a straight line that passes the vertical line test.
The vertical line test is where you try to draw a single vertical line through more than one point on the function curve. In this case, we cannot draw such a vertical line, so the graph passes the vertical line test.
Plugging any input x into y = x-5 leads to exactly one y output value. This is another way to see we have a function.
hiii i have a question on math:)
PQR = 150°
Step-by-step explanation:Hi there !
PQR = PQS + SQR
12x - 6 = 16 + 9x + 17
12x - 9x = 16 + 17 + 6
3x = 39
x = 13
PQR = (12×13 - 6)° = (156 - 6)° = 150°

Step-by-step explanation:
1. SEASONING A health food store sells seasoning blends in bulk. One blend contains
20% basil. Sheila wants to add pure basil to some 20% blend to make 16 ounces of her
own 30% blend. Let b represent the amount of basil Sheila should add to the 20% blend.
Answer:
2
Step-by-step explanation:
From the question, One blend contains 20% basil.
Then here we have 20/100= 0.20
Sheila wants to add pure basil to some 20% blend to make 16 ounces of her
own 30% blend.
(30/100)B =(20/100)B +(amount Sheila want to add to make 16 ounces)
amount Sheila want to add to make 16 ounces= (30/100)B - (20/100)B
= 0.5B
amount Sheila want to add to make 16 ounce= (16-B)
0.5B= (16-B)
B=14
If substracted from the 16ounce we have 2.

HELP PLEASE!!!
i need help please!!!!!!!
Answer:
see explanation
Step-by-step explanation:
Consider the difference between consecutive y values.
There is a difference of 3 between them, that is
0 - (- 3) = 3 - 0 = 6 - 3 = 9 - 6 = 3
This indicates there is a relationship between input and output
To obtain the output, multiply the input by 3 and subtract 9
This relationship can be expressed as
y = 3x - 9
Answer:
y = 3x - 9.
Step-by-step explanation:
The values of y increase by 3 for every increase of 1 in x.
This is an arithmetic sequence and when x = 1, y = -6.
The relationship is
y = -6 + 3(x - 1)
y = 3x - 6 - 3
y = 3x - 9.

what's the answer to 7x + 5 = ( 4x + 3 )
Answer:
x=-2/3
Step-by-step explanation:
[tex]7x+5=4x+3\\3x+5=3\\3x=-2\\x=\frac{-2}{3}[/tex]
Answer:
Step-by-step explanation:
7x + 5 = (4x + 3)
remove parentheses, they aren't needed here:
7x + 5 = 4x + 3
group them (subtract 5 and 4x from each side):
7x - 4x = 3 - 5
simplify:
3x = -2
divide both sides by 3:
x = -2/3

There are 15 people in the swimming club.
The ratio of girls to boys is 2 : 3.
How many girls and how many boys are there?
Answer:
6 girls, 9 boys
Step-by-step explanation:
Step 1:
2 : 3 15 people
Step 2:
2x + 3x = 15 people We can turn the ratio into variables
Step 3:
5x = 15 people We can now solve for the variable
Step 4:
x = 3 Now we know that the variable is 3
Step 5:
3 × 2 = 6 We can now solve for the number of girls
Step 6:
3 × 3 = 9 And we can also solve for the number of boys
Answer:
6 girls, 9 boys

Find the equation of a line parallel to y=6x-4 and through point (-2,14)
Step-by-step explanation:
Substitute the slope from original line (3 in this case) into the equation of the line
$ y = \red 3 x + b $
Step 2
Substitute the given point (1, 7) into the x and y values
$ y = \red 3 x + b \\ 7 = \red 3 (1) + b $
Step 3
Solve for b (the y-intercept )
$ \begin{align*} 7 &= 3 (1) + b \\ 7 &= 3 + b \\ -3 & -3 \\ \hline \\ 4 &= b \\ \end{align*} $
Step 4
Substitute this value for 'b' in the slope intercept form equation $ y = 3x + 4 $

how to use the gcf and distributive property to find each some: 32+48, 15+57, 98+14, 55+88
Answer:
For the first two:
16(2+3)
3(5+19)
Step-by-step explanation:
To find the gcf, you must list the factors of both numbers, and whichever one is greatest, you would put on the outside. Like 16 is the gcf of 32 and 48, so that number remains on the outside. Now, for the inside numbers, 16 times what equals 32? 16 times 2. 16 times what equals 48? 16 times 3 equals 48. Put those in the parenthesis, and put an addition sign in between them.
The use of greatest common factor and distributive property to find the sum is discussed above.
What is the distributive property of addition?The distributive property of addition state that -
a x (b + c) = (a x b) + (a x c)
Given are the following expressions -
32+48
15+57
98+14
55+88
We will first factor out the highest common factor and then apply the distributive property as follows.
[1]
32 + 48
8(4 + 6)
(8 x 4) + (8 x 6)
32 + 48
80
[2]
15 + 57
3(5 + 19)
(3 x 5) + (3 x 19)
15 + 57
72
[3]
98 + 14
14(7 + 1)
14 x 7 + 14 x 1
98 + 14
112
[4]
55 + 88
11(5 + 8)
11 x 5 + 11 x 8
55 + 88
143
Therefore, the use of greatest common factor and distributive property to find the sum is discussed above.

What is the absolute value of -20?
Use the number line to answer the question.
0-20
OO
O 20
O 40
Answer: |-20| = 20
Step-by-step explanation:
The absolute value of any number is always going to be that number in it's positive form. In this case, even if it was 20 the absolute value would still be 20. The absolute value is the number's distance from 0. So even if the integer is negative or not, it's distance will still be the same. Hope this helps !
The absolute value of -20 is 20.
To find the absolute value of -20, use the number line representation. The number line helps us visualize the position and magnitude of numbers.
At zero and move to the left. We first locate -20 on the number line. Starting from zero, 20 units to the left, which lands us on the point representing -20.
To find the absolute value, disregard the sign and consider only the magnitude measure the distance from zero to -20 without considering the direction the distance from zero to -20 is 20 units.
