Step-by-step explanation:
the first one is wrong because if they were both 0 than they would have to equal 0
the second one is wrong because no number works
the third one is wrong because it works on the second one but when you plug it into the first equation you get 95 = 35 which is incorrect.
D is the correct choice.
A store is having a sale on jelly beans and almonds. For 6 pounds of jelly beans and 2
pounds of almonds, the total cost is $16 . For 3 pounds of jelly beans and 5 pounds of almonds, the total cost is $13. Find the cost for each pound of jelly beans and each pound of almonds.
The cost of each pound of jelly beans is $ 2.25 and cost of each pound of almond is $ 1.25
Solution:
Let the cost of each pound of jelly beans is "a"
Let the cost of each pound of almond is "b"
For 6 pounds of jelly beans and 2 pounds of almonds, the total cost is $16
Therefore, we frame a equation as:
6 pounds of jelly beans x cost of each pound of jelly beans + 2 pounds of almonds x cost of each pound of almond = 16
[tex]6 \times a + 2 \times b = 16[/tex]
6a + 2b = 16 --------- eqn 1
For 3 pounds of jelly beans and 5 pounds of almonds, the total cost is $13
Therefore, we frame a equation as:
3 pounds of jelly beans x cost of each pound of jelly beans + 5 pounds of almonds x cost of each pound of almond = 13
[tex]3 \times a + 5 \times b = 13[/tex]
3a + 5b = 13 ----------- eqn 2
Let us solve eqn 1 and eqn 2
Multiply eqn 2 with 2
6a + 10b = 26 --------- eqn 3
Subtract eqn 1 from eqn 3
6a + 10b = 26
6a + 2b = 16
( - ) -------------------------
8b = 10
[tex]b = \frac{10}{8} = 1.25[/tex]
b = 1.25Substitute b = 1.25 in eqn 1
6a + 2(1.25) = 16
6a + 2.5 = 16
6a = 13.5
a = 2.25Thus cost of each pound of jelly beans is $ 2.25 and cost of each pound of almond is $ 1.25
A 2-column table has 5 rows. The first column is labeled x with entries negative 2, negative 1, 0, 1, 2. The second column is labeled f (x) with entries 12.5, 2.5, 0.5, 0.1, 0.02.
Which exponential function is represented by the table?
f(x) = 0.2(0.5x)
f(x) = 0.5(5x)
f(x) = 0.5(0.2x)
f(x) = 0.2(0.2x)
Answer:
[tex]f(x)=0.5\cdot (0.2)^x[/tex]
Step-by-step explanation:
Given the table
[tex]\begin{array}{cc}x&f(x)\\ \\-2&12.5\\ -1&2.5\\0&0.5\\1&0.1\\2&0.02\end{array}[/tex]
The exponential function can be written [tex]f(x)=a\cdot b^x.[/tex] To find [tex]a[/tex] and [tex]b,[/tex] substitute some values:
When [tex]x=0,\ f(x)=0.5,[/tex] then
[tex]0.5=a\cdot b^0\Rightarrow a=0.5\ [ b^0=1][/tex]
When [tex]x=1,\ f(x)=0.1,[/tex] then
[tex]0.1=0.5\cdot b^1\Rightarrow 0.5b=0.1,\ b=0.2[/tex]
Thus,
[tex]f(x)=0.5\cdot (0.2)^x[/tex]
Check remaining values:
[tex]f(-2)=0.5\cdot 0.02^{-2}=0.5\cdot 5^2=0.5\cdot 25=12.5\\ \\f(-1)=0.5\cdot 0.2^{-1}=0.5\cdot 5=2.5\\ \\f(2)=0.5\cdot 0.2^2=0.5\cdot 0.04=0.02[/tex]

Find the coordinates of the midpoint of the line segment with the endpoints C(1,0) and D(5,4)
Answer:
(3, 2 )
Step-by-step explanation:
Given the endpoints are (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ 0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) [
Here (x₁, y₁ ) = (1, 0) and (x₂, y₂ ) = (5, 4), thus
midpoint = [0.5(1 + 5), 0.5(0 + 4) ] = (0.5(6), 0.5(4)) = (3, 2 )
Answer:
(3,2)
Step-by-step explanation:
To find a midpoint of two given points, we can use the formula:
[tex](x_{m} ,y_{m} ) = (\frac{x_{1} +x_{2} }{2} , \frac { y_{1} +y_{2}}{2})[/tex]
(i.e. we just take the average of the x coordinates, and similarly, the average of the y coordinates).
so we get:
midpoint = ( (1+5)/2, (0+4)/2 )
= (3, 2)
The difference of r and 18 is equal to five
Answer: 23

R=23
The difference of r and 18 means subtraction: r - 18 = 5
To isolate r, you add 18:
r = 18 + 5 or 23
r = 23

There are sparrows and cardinals that feed at Mrs. Sims bird feeder. The ratio of sparrows to cardinals is 3:1. There are at least 7, but less than 11 sparrows that eat at Mrs. Sims bird feeder. Put an S in the grid below to show the number of sparrows and a C to show the number of cardinals. There may be extra squares. (See attachment)
Answer:
Please find the grid of Sparrows and Cardinals below.
Step-by-step explanation:
Ratio 3:1 of Sparrows to Cardinals
There are at least 7, but less than 11 sparrows that eat at Mrs. Sims bird feeder
Let's build the grid for sparrows and cardinals, this way:
Sparrows = 7 - 8 - 9 - 10 - 11
Cardinals = 2 - 3 - 3 - 3 - 4
For calculating the number of cardinals we use the ratio 3:1 and round the number of cardinals to the next whole number.
Number of sparrows 7 to 11
Number of cardinals 2 to 4

Part A: Write an equation of a line that is perpendicular to the line y = 2/3x + 5 and passes through the point (4, 0).
Part B: Explain how you determine the equation in 3-4 sentences using at least 6 of the words below.
Slope
y-intercept
x-intercept
perpendicular
opposite
reciprocal
substituted/substitution
slope-intercept
ordered pair
Step-by-step explanation:
First you need to make a line perpendicular to y=2/3x+5. To do that you have to know that, if we use y=ax+b, a1*a2=-1. That is if a1 and a2 are perpendicular. So we get 2/3*a2=-1. -1/ 2/3=a2. a2=-1.5. We get y=-1.5x+b. Fill in (4,0) on y=-1.5x+b abd we get 0=-1.5(4)+b. b=6
Answer:
y = (-3/2)x - 6
Step-by-step explanation:
slope of the line y= 2/3x + 5
slope = 2/3
for two perpendicular lines
slope1*slope2 = -1
so, slope2 = (-1)*(3/2) = -3/2
hence for it to pass (4,0)
slope2=(y2 - y1)/(x2 - x1)
-3/2 = (y - 0)/(x - 4)
cross multiplying
-3x -12 = 2y
the equation of the line is
y = (-3/2)x - 6
3x +y = 14
Rewrite equation in slope intercept form solve for y
To rewrite the equation in slope-intercept form and solve for y, we isolate y on one side of the equation by subtracting 3x from both sides. The resulting equation is y = -3x + 14.
Explanation:To rewrite the equation in slope-intercept form and solve for y, we need to isolate y on one side of the equation.
Given the equation 3x + y = 14, we can start by subtracting 3x from both sides to get y alone.
The equation becomes y = -3x + 14, which is now in slope-intercept form (y = mx + b) where the slope (m) is -3 and the y-intercept (b) is 14.

Select TWO equations that have infinitely many solutions.
A.
2(7 – 4x) = 4(5 – 2x) – 6
B.
6(x – 9) = 6x – 54 + x
C.
4(x + 4) = 2(2x + 5) + 6
D.
5(x – 8) + 10 = 5(x + 2)
Answer: A. 2(7 – 4x) = 4(5 – 2x) – 6
C. 4(x + 4) = 2(2x + 5) + 6
Step-by-step explanation:
Infinitely solution means when all numbers are solutions . Checking the equations given one by one
A. 2(7- 4x ) = 4(5 - 2x ) - 6
Expanding , we have
14 - 8x = 20 - 8x - 6
14 - 8x = 20 - 6 - 8x
14 - 8x = 14 - 8x , this is just a typical example of infinitely many solutions because any value of x chosen will satisfy the equation.
B. 6(x - 9 ) = 6x - 54 + x
Expanding , we have
6x - 54 = 6x + x - 54
6x - 54 = 7x - 54
collecting the like terms
6x - 7x = -54 + 54
- x = 0
x = 0
This equation has just one solution at x = 0 , because 0 is the only value of x that will satisfy the equation
C. 4( x + 4 ) = 2 ( 2x + 5 ) + 6
4x + 16 = 4x + 10 + 6
4x + 16 = 4x + 16
This equation also have infinitely many solutions
D. 5 ( x - 8 ) + 10 = 5 ( x + 2 )
5x - 40 + 10 = 5x + 10
5x - 30 = 5x + 10
This equation has no solution.
Therefore , the equations with infinitely many solutions are equations A and C

Raphael runs every day for several weeks. He runs for 35 days in a row. How many weeks did he run?
Answer:
5 weeks
Step-by-step explanation:
There are 7 days in a week.
5 weeks * 7 days = 35 days.
Raphael ran for a total of 5 weeks.
To calculate how many weeks Raphael ran, we need to divide the number of days he ran by the number of days in a week.
Raphael ran for 35 days.
Since there are 7 days in a week, we divide 35 by 7:
35 days / 7 days per week = 5 weeks
Therefore, Raphael ran for 5 weeks.

Write an equation of the lines that passes through the given point and is parallel to the given line.
Answer:
Step-by-step explanation:
6x - y = 1
6x - 1 = y.....rearrange
y = 6x - 1......slope is 6. A parallel line will have the same slope.
y = mx + b
slope(m) = 6
(-5,-5)...x = -5 and y = -5
now we sub and find b, the y int
-5 = 6(-5) + b
-5 = -30 + b
-5 + 30 = b
25 = b
so ur equation is : y = 6x + 25 <==
Joe made a scale drawing of the community pool in his town. the pool has a perimeter of 77 meters, what is the length and width in meters?
Answer:
The length of the pool is 28 meters and the width of the pool is 10.5 meters.
Step-by-step explanation:
In the scale drawing of Joe, the community pool has (length : width) = 8 : 3
Let the actual length of the pool is 8x meters and the actual width is 3x meters.
Now, given that the actual pool has a perimeter of 77 meters.
So, 2(8x + 3x) = 77
⇒ 22x = 77
⇒ x = 3.5
So, the length of the pool is 8x = 8(3.5) = 28 meters and the width of the pool is 3x = 3(3.5) = 10.5 meters. (Answer)
Answer:
The length of the pool is 28 meters and the width of the pool is 10.5 meters.
