9. Fred bought 24 new baseball cards for $50. There were two types of cards. One type cost $1 per card, and the other cost $3per card. Define the variables, and write a system of equations to find the number of each type of card he bought. Then solve the system using the best method for the situation.
Answer:1$ cards = 11 cards 3$ cards= 13
Step-by-step explanation:the first equation is -x-y=-24 and the second is x+3y=50. Solving them as a system will get 2y=26 to y=13 then plug in 13 to the y for -x-y=-24 to get 11. Mr jacobs is hard I know lol. Use elimination by subtraction and keep the first equation as x+y=24 and then flip to negative

Hello, I really truly need help please, PLZ! Thanks!
(5 screenshots included)
Answer:
1. Second Choice
2. Positive
3. Line B
4. Line D
5. Horizontal
Step-by-step explanation:
First ScreenshotThe y-intercept is the value of b —
[tex]y = mx + b[/tex]
where m = slope and b = y-intercept.
Looking from the graph, the graph passes y-axis at (0,1) which is y-intercept.
Basically (0,a) is y-intercept.
Thus, our y-intercept is (0,1)
Second ScreenshotThe slope is positive. If the slope is negative, it would face opposite.
For zero slope, the graph will become a horizontal line.
An undefined slope is the vertical line graph.
Third ScreenshotLine B has zero slope. As said, the zero slope will turn the graph into a horizontal line.
Fourth ScreenshotLine D has an undefined slope. Read Third Screenshot.
As said, an undefined slope is the vertical line.
Fifth Screenshot[tex]y = - 3[/tex]
This is called Constant Function where the graph is a horizontal line. For a vertical line, it must be x = a (where a is constant)
FYI,
y = a — horizontal
x = a — vertical
While on vacation in Bloomington, Ashley went out for a dinner that cost $20. If sales tax in Bloomington is 10% and Ashley left a 15% tip on $20, what was the total cost of her meal?
Answer:
$25
Step-by-step explanation:
Given that:
Cost of Ashley's dinner in Bloomington = $20
Sales tax = 10%
Tip = 15% on $20
To find:
Total cost of the meal ?
Solution:
Let us find the sales tax first of all.
Sales tax is 10% of the total bill.
Therefore, sales tax = 10% of $20
[tex]\Rightarrow \dfrac{10}{100}\times 20\\\Rightarrow \$2[/tex]
Tip left is 15% of the total bill.
Therefore, tip = 15% of $20
[tex]\Rightarrow \dfrac{15}{100}\times 20\\\Rightarrow \$3[/tex]
Now, total cost of the meal = Food cost + Sales tax + tip
Total cost of the meal = $20 + $2 + $3 = $25
Help!! Find the indicated angle measure. Show your work.
Answer:
m∠NPM = 101
Step-by-step explanation:
Since LM is a straight line, Angle LPM and Angle NPM have to equal 180 degrees (they are supplementary), so we make the equation:
180-79=measure of angle NPM
m∠NPM = 101
Answer:
<NPM = 101°
Step-by-step explanation:
<NPM = 180° - <LPN ( because LPM is a straight line and it should measure 180°)
<NPM = 180° - 79°
<NPM = 101°

Answer:
B. Positive slope
Step-by-step explanation:
The line on the graph is positive, as it grows from left to right.
Answer:
Positive Slope
Step-by-step explanation:
The line goes up, which means that it's positive. To be exact the line equation is y = 3x + 1. The slope (3) is positive, which proves that its a positive slope, not negative.

Answer:
20 Input
10 output
Step-by-step explanation:
Here, we want to select the input and output that works
From the diagram, the correct answer is 20 and 10
Let us look at how the rule is followed;
divides input by 2
20/2 = 10 which is the output
Subtract 10 to get output
20-10 = 10

use the quotient rule to find the derrivatives of 3/x^2
Answer:
f'(x) = -6/x³
Step-by-step explanation:
We are given;
f(x) = 3/x²
Using quotient rule, we can write as;
f(x) = g(x)/h(x)
To find the derivative, from quotient rule, we can write;
f'(x) = [(h(x)*g'(x)) - (g(x)*h'(x))]/(h(x))²
g'(x) = 0
h'(x) = 2x
Thus;
f'(x) = [(x²*0) - (3*2x)]/(x²)²
f'(x) = -6x/x⁴ = -6/x³
f'(x) = -6/x³

Work out the area of the trapezium.
Answer:
58.29 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (a + b) , substitute given values into formula
A = [tex]\frac{1}{2}[/tex] × 6.7 × (7 + 10.4)
= 3.35 × 17.4
= 58.29 cm²
A team's total salaries is $4,614,244. The team would like to bring the total down to $3.5 million. What would be the percentage decrease in the team's total salary?
Answer:
24.14%
Step-by-step explanation:
Given that,
A team's total salaries is $4,614,244.
The team would like to bring the total down to $3.5 million = $3500000
We need to find the percentage decrease in the team's total salary. The percentage decrease/increase in any value is givenby :
[tex]\%=\dfrac{\text{change in population}}{\text{initial population}}\times 100\\\\=\dfrac{3500000-4,614,244}{4,614,244}\times 100\\\\=24.14\%[/tex]
So, the percentage decrease in the team's total salary is 24.14%.

the equation of the line which has a gradient of 3 and passes through the point (-1,3)
Answer:
Call the line (d): y = ax + b
(d) intersects the vertical axis at the point where the intersection is 3 ⇒x = 0, y = 3 Instead of (d) we have: b = 3
(d) intersects the horizontal axis at the point where the coordinate is -1 ⇒x = −1, y = 0 Instead of (d) we have: −a + b = 0
Replace into b = 3 into -a + b = 0 we have: −a + 3 = 0⇔a = 3
So the equation for the line is y = 3x + 3
