Which inequality statement best represents the graph?

We are given the graph of a parabola with a shaded portion, representing the inequality.

We can see that the parabola opens up rather than down, so we can instantly eliminate options C and D.

When f(x) is greater than the expression, the area within it is shaded.

Answer choice B best represents this.

Answer:

The answer to your question is the second option f(x) ≥ 2x² + 4x

Step-by-step explanation:

In the graph, we observe that we need the up area of the parabola so the inequality must be ≥. From this observation, we discard the options one and three.

The last equation is a parabola that opens downwards not upwards as we notice in the graph so we discard the fourth option.

Gnom [1K]

Answer:

$(5,-4)$

Step-by-step explanation:

SOLVE BY SUBSTITUTION:

STEP 1: Replace all occurrences of $y$ with $-3x+11$ in each equation.

$-3x+22=7\\y=-3x+11$

STEP 2: Solve for $x$ in the first equation.

$x=5\\y=-3x+11$

STEP 3: Replace all occurrences of $x$ with $5$ in each equation.

$y=-4\\x=5$

At the taco truck an order of 1 taco and 3 quesadillas cost $ 26.50. An order if 3 tacos and 1 quesadilla cost $19.50. for 5 tac

gladu [14]

Answer:

The cost of 1 taco = $4

The cost of 1 quesadilla = $7.50

Step-by-step explanation:

Let the cost of tacos be x and the cost of quesadillas be y.

<h3><u>Given condition:</u></h3>

x + 3y = 26.50 ------------------(1)

3x + y = 19.50 -------------------(2)

Multiply Eq. (2) by 3

3(3x + y) = 19.50 * 3

9x + 3y = 58.5 -----------------(3)

Subtract Eq. (3) from (1)

x + 3y - 9x - 3y = 26.50 - 58.50

x - 9x = -32

-8x = -32

8x = 32

Divide 8 to both sides

x = $4

Put x = 4 in (1)

4 + 3y = 26.50

Subtract 4 to both sides

3y = 26.50 - 4

3y = 22.50

Divide 3 to both sides

y = $7.50

So,

The cost of 1 taco = $4

The cost of 1 quesadilla = $7.50
