Answer:
20
Step-by-step explanation:
40 x 50% = 20
So 50% of 40 equals to 20. Now, since it says decreased by 50%, we have to subtract 20 from 40 because we already know that 20 is the 50%. So 40 - 20 gives you 20.

Francine and Cheryl received equal scores on a test made up of multiple choice questions and an essay. Francine got 34 multiple choice questions correct and received 14 points for her essay. Cheryl got 30 multiple choice questions correct and received 22 points for her essay.
How many points was each multiple choice question worth?
Enter your answer in the box.
Answer:
Francine's score: 34x + 14
Cheryl's score: 30x + 22
Equal scores => 34x + 14 = 30x + 22
34x - 30x = 22 - 14

write the log equation as an exponential equation. you do not need to solve for x.
Answer:
[tex]5^{1/6} =2x[/tex]
Step-by-step explanation:
Log and exponential forms are inverses. Additionally, the information from one can be used to write in it another form. In a log equation, there are three parts. The formula is [tex]log_{b}(x)=y[/tex]. The formula for exponential equations is [tex]b^y=x[/tex]. This means to find this equation in exponential form write 5 as the base, 1/6 as the power, and 2x as the other side of the equation. This looks like, [tex]5^{1/6} =2x[/tex].

The local community center hosted a marathon as a fundraiser. Runner A completed the marathon with a time of 4.37 hours. Runner B completed the marathon in 4.29 hours. Which runner completed the race faster (by having a lower time)? Explain how you know. (100 points + brainliest)
Based on the information given in the question, the completion time of runner B is lower than that of Runner A ; Hence, runner B completed the race faster.
Given the running time of two runners :
Runner A = 4.37Runner B = 4.29The runner with the lesser running time will complete the marathon faster as this means he has a higher speed.
Comparing the running times of both runners :
4.37 > 4.29Therefore, Runner B completed the race faster than runner A.

y = −2x
y = fraction negative 1 over 2x
y = 2x
y = fraction 1 over 2x
Answer:
y = -2
Step-by-step explanation:
The graph passes through (0,0) and (-1,2).
The equation of a line passing through the origin is of the form,
y = mx
We now substitute (-1,2) to obtain,
2 = -m
This implies that,
m = -2
The equation is
y = -2

Answer:
1st one: Reflection
2nd one: Rotation
3rd one: Rotation
4th one: Translation
Step-by-step explanation:
1: These figures are flipping across the y-axis, meaning it's a reflection.
2: This figure rotated 90° clockwise, so it's a rotation.
3: This figure rotated 180° both clockwise and counterclockwise, so it's a rotation.
4: This figure just shifted down and to the right, so it's a translation.

Justin is taking a taxi cab to pick up his car from the auto shop. The taxi charges an initial fee of $5.00 and additional $2.50 for each mile the taxi drives. Write an equation using x as the number of miles, to determine how many miles the taxi drove if Justin spent $25.00. Use your equation for the number of miles. (Define the variable please, write an equation, and solve & label:))
Answer:
x = 8
Step-by-step explanation:
Given the initial fee of $5.00, and the additional cost of $2.50 for every mile the taxi drives:
We can establish the following cost function:
C(x) = 2.50x + 5.00
Where:
C(x) = total cost of taxi fare (same as the variable, "y" in linear equation)
x = number of miles driven
$5.00 = initial or flat fee (same as the y-intercept, "b," in linear equation).
We can find out the number of x miles the taxi drove for the $25.00 total cost that Justin paid for the fare:
C(x) = 2.50x + 5.00
$25 = 2.50x + 5.00
Subtract 5.00 from both sides of the equation:
$25 - 5.00 = 2.50x + 5.00 - 5.00
$20 = 2.50x
Divide both sides by 2.50 to solve for x:
[tex]\frac{20}{2.50} = \frac{2.50x}{2.50}[/tex]
8 = x
Justin spent $25 for a taxi ride that travelled for 8 miles.

4(y-2)=-0.6(y+0.3 what is the answer and how to do it
Answer:Solution for 0.3(y-2)+0.4y=0.3y-0.6 equation:
0.3(y-2)+0.4y=0.3y-0.6
We move all terms to the left:
0.3(y-2)+0.4y-(0.3y-0.6)=0
We add all the numbers together, and all the variables
0.4y+0.3(y-2)-(0.3y-0.6)=0
We multiply parentheses
0.4y+0.3y-(0.3y-0.6)-0.6=0
We get rid of parentheses
0.4y+0.3y-0.3y+0.6-0.6=0
We add all the numbers together, and all the variables
0.4y=0
y=0/0.4
y=0
