using the standard form ax^2+bx+c=0 of the given quadratic equation, factor the left hand side of the equation into two linear f

Galina-37 [17]

Answer:

See below

Step-by-step explanation:

Since you didn't give an actual quadratic equation and just the standard form equation, I will reduce ax^2+bx+c=0:

(ax+p)(x+q) where p+q=b and pq=c

5(3 – x) + 1 = 3(x+4)

Yuri [45]

Step-by-step explanation:

<h3>✞︎Given</h3>

5(3-x)+1=3(x+4)

Solve Equation

<h3>✞︎Solution</h3>

$\tt\large\underline{15-5x+1=3x+12}$

$\large{✰} \bf \underline\color{purple}{16-5x=3x+12}$

$\tt\large\underline{\longmapsto16-12-3x+5x}$

$\tt\large\underline{\longmapsto4-8x}$

$\tt\large\underline{\longmapsto8x=4}$

$X=\longmapsto\sf \dfrac{\cancel{4}}{\cancel{8}}$

$\tt\large\underline{\longmapsto \: \: \: \: x = \frac{1}{2} }$

Jerome bought 2 adult tickets and 7 student tickets for a play.How much did he spend?Show any equations used.Ticket pricesStuden

Stels [109]

From the information given,

Students ticket = $4

Adult ticket = $6

Let student ticket be x, and adult ticket be y.

This means;

$\begin{gathered} Cost=2y+7x \\ C=2(6)+7(4) \\ C=12+28 \\ C=40 \end{gathered}$

ANSWER:

The calculations show that Jerome spent a total of $40

Which equation is represented by the graph shown in the image? A. y + 2= x B. y + 1= x C. y - 1= x D. y - 2= x Please show ALL w

olasank [31]

Answer:

A. y + 2= x

Step-by-step explanation:

Which equation is represented by the graph shown in the image?

A. y + 2= x

B. y + 1= x

C. y - 1= x

D. y - 2= x

Please show ALL work! <3

The graph shown has a slope of +1 and a y intercept of -2.

All given answer choices have a slope of +1, so that's not the problem.

We need one that has a y-intercept of -2, or the equation should be

y = x-2, or equivalently y+2 = x

which corresponds to answer choice A.

Lou’s Shoes is having its annual Flag Day Sale and is offering a 25% discount on all regularly priced shoes. Kayla spends $13.50

patriot [66]

The easiest way to think of these is to put them in terms of percentages. Obviously, if you are SAVING 25%, you are SPENDING 75%. So if she SPENDS 13.50, we can easily use the 75% in an equation. $13.50 = .75x, with x being what the shoes cost originally. The .75 indicates that she is spending 75% of what the original cost is. You don't have any examples to pick from, but this is the best way to explain what one of the equations could be. You could also base it on money saved, but the equation is not quite as neat.
