Answer:

14 points

Step-by-step explanation:

The second test Lee did was 13 points fewer than the first test, which was 91 points, so the second test's score is 91 - 13 = 78 points.

The third test had the score of 92, so this is the highest score, and the lowest score is the second one: 78 points.

The difference between Lee's highest and lowest scores is:

92 - 78 = 14 points

Sara is mixing together a fruit punch for a party. She's made 4 gallons of punch with a mixture of 50% juice. Her mother tells h
Nata [24]
\bf \begin{array}{lccclll}
&amount(gallons)&juice&\textit{juice amount}\\
&--------&-----&-----\\
\textit{50\% punch}&4&0.50&(4)(0.50)\\
\textit{pure juice}&x&1.00&(x)(1.00)\\
-----&-----&-----&-----\\
mixture&4+x&0.60&(4+x)(0.60)
\end{array}

notice, that, pure juice is 100% juice, dohhh, thus 100/100 = 1.00
50% is 50/100 or 0.50 in decimal format

so..... whatever those two quantities amount to, that is, the 50% and pure juice, or (4)(0.50) + (x)(1.00)
they will equal the mixture desired 60% juice, or 0.60, namely (4+x)(0.60)

thus    (4)(0.50) + (x)(1.00) = (4+x)(0.60)

solve for "x"

What is the vertex of y<∣x−3∣+5​
Tcecarenko [31]

Answer:

(3, 5)

Step-by-step explanation:

The graph is is the standard y=|x| except the values tells you that x shifts 3 (within the absolute value or parentheses x does the opposite) to the right and the y value shifts 5 up (numbers outside parentheses affects y and does what it says). You can try using a table of values then graphing to check your answer.

2 14 in the lowest terms
SIZIF [17.4K]
Solutions 

To convert 2/14 into lowest terms you have to divide by the greatest common factor. The greatest common factor of 2 and 14 is 2. 

2 ÷ 2 = 1 
14 ÷ 2 = 7 

1/7 is in lowest terms

PLS HELP URGENT MAX AMOUNT OF POINTS WILL BE GIVEN AND PLS DO NOT ANSWER IF UNSURE OR YOU WILL BE REPORTED BY ME AND BRAINLIEST
luda_lava [24]

Answer:

f(x) is shifted to the left 2 units of g(x)

f(x) will not be shifted vertically since we did not add anything to g(x)

Step-by-step explanation:

g(x) = x^2+2

f(x) = g(x+2)

When we shift  with h(x+c)  it is a horizontal shift

                  if c>0 it moves it left  c units

                  if c< 0 it moves it right c units

Since c is 2, this is shifted left 2 units

f(x) is shifted to the left 2 units of g(x)

When we shift  with h(x)+c  it is a vertical shift

                  if c>0 it moves it up  c units

                  if c< 0 it moves it down c units

f(x) will not be shifted vertically since we did not add anything to g(x)
