which expression is equivalent to (3x+4)(7x-2)​

Answers

Answer:

21x² + 22x - 8

Step-by-step explanation:

(3x+4)(7x-2)​ = 21x² - 6x + 28x - 8 = 21x² + 22x - 8

Answer:

B.

Step-by-step explanation:

Let's use the FOIL (First, Outside, Inner, Last) method.

We need to multiply the first terms in each pair of parentheses, which are

3x and 7x.

Multiplying, we get [tex]21x^2[/tex].

We multiply the outside terms in each pair, which are 3x and -2.

Multiplying, we get [tex]-6x[/tex]. Remember that since -2 is negative, then the whole product is negative.

We need to multiply the inner terms now. They are 4 and 7x.

Multiplying, we get [tex]28x[/tex].

Finally, we multiply the last terms in each pair of parentheses. they are 4 and -2.

Multiplying, we get [tex]-8[/tex].

Now, we put the terms together.

[tex]21x^2-6x+28x-8[/tex]

We can combine -6x, and 28x. Doing this, we get

[tex]21x^2+22x-8[/tex]. Which gives us B.

I hope this helped.

Please help me with my algebra homework (Attachment)

Answers

Answer:

D.

Step-by-step explanation:

To see if a line is parallel to y = -(2/3)x + 8 you need to check if the coefficients at y and x are of the same ratio. This immediately removes answers A and C, because of the wrong sign at x compared to y.

What's left is to see which of the answers B and D passes through (4, -5) by inputting x = 4 and y = -5

B.

left = -5 - 5 = -10

right = -(2/3)(4 + 4) = -16/3

So it's D. Let's verify:

D.

left = -5 + 5 = 0

right = -(2/3)(4 - 4) = 0

Checks out.

Answer:

Option D

Step-by-step explanation:

→ Find the gradient of the parallel line

[tex]y=-\frac{2}{3} x+c[/tex]

→ Substitute in the coordinates as x and y values to find c

[tex]5=-\frac{2}{3} *-4+c[/tex]

→ Simplify

[tex]5=\frac{8}{3} +c[/tex]

→ Minus  [tex]\frac{8}{3}[/tex]  from both sides to find c

[tex]c = \frac{7}{3}[/tex]

→ Expand out all options and then see which one contains all the numbers above

Option D

Find the value of a and b.
2x + 5y = 9
3x – 2y = 4
x= ?
y= ?

Answers

2x + 5y = 9
3x - 2y = 4

1) Make the x equal the same (find common factor) which is 6
2) Time the whole equation by the factor for example 2x3= 6, times the top equation by 3. The bottom 3x2=6, times the bottom equation by 2:

6x+15y=27
6x-4y=8
(Cancel the x)

Left with: 19y =19 (15- -4y =19y) (27-8=19)
Therefore y = 1

Now substitute y=1 into the equation to find x

6x + 15(1)= 27
6x + 15 = 27
6x = 12
X = 2

Answers:
X=2, Y=1
