Answer:

The Answer Is E!

Step-by-step explanation:

To solve this equation., you have to try every solution and the only one that perfectly completes both statements is answer E.

We subtract the $1.15 from $2.10 if this is the price of one taco, leaving the price of a small cup of coffees price ($2.10-$1.15=$0.95 for a small cup of coffee

To check it fits both statements, we multiply the price of one coffee by 3 ()$0.95×3=$2.85 for three small coffees\

Next, we multiply $1.15 (one taco) by 2 to fill in the expression ($1.15×2=$2.30)

Finally, we add both the prices of the 3 coffees and two tacos which adds up to a perfect $5.15, justifying the answer

GIVEN:

Cost of a taco and a cup of tea = $2.10

x + y = 2.10 ...(1)

Cost of 2 tacos and 3 cup of tea = $5.15

2x + 3y = 5.15 ...(2)

ANSWER:

On solving eq(1), we get

x = 2.10 – y

Substitute the value of x in eq(2), we get

2(2.10 – y) + 3y = 5.15
4.20 – 2y + 3y = 5.15
y = 5.15 – 4.20
y = 0.95

So, x = 2.10 – 0.95

x = 1.15

Hence, Cost of a taco is $1.15

So, Correct choice - [E] $1.15

Suppose f (x) = x^2. Find the graph of f(x+2)

NISA [10]

$\bf ~~~~~~~~~~~~\textit{function transformations}
\\\\\\
% templates
f(x)={{ A}}({{ B}}x+{{ C}})+{{ D}}
\\\\
~~~~y={{ A}}({{ B}}x+{{ C}})+{{ D}}

f(x)={{ A}}\sqrt{{{ B}}x+{{ C}}}+{{ D}}

$\bf \bullet \textit{ horizontal shift by }\frac{{{ C}}}{{{ B}}}\\

~~~~~~if\ {{ D}}\textit{ is negative, downwards}\\\\
~~~~~~if\ {{ D}}\textit{ is positive, upwards}\\\\
\bullet \textit{ period of }\frac{2\pi }{{{ B}}}$

with that template in mind,

$\bf f(x)=x^2\qquad \quad f(x+2)=(x+2)^2\implies f(x+2)=\stackrel{A}{1}(\stackrel{B}{1}x\stackrel{C}{+2})^2\stackrel{D}{+0}$

C = 2 B = 1 C/B = 2/1 or +2, horizontal left shift of 2 units

f(x) shifted left by 2 units is f(x+2).

Jaheem has a goal running a total of 125 miles this month. Each day that he ran, he ran 7 miles. Which expression could Jaheem u

VashaNatasha [74]

Answer:

a. 125 – 7d

Step-by-step explanation:

Let d be the number of days.

Given the following data;

Total distance (month) = 125 miles

Distance covered per day = 7 miles

To determine how many miles he has left to run after running for "d" days, this mathematical expression can be used;
