Please help me with my algebra homework (Attachment)
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

Make x the subject of the formula
x/3z = y-2
Answer:
x = 3z(y - 2)
Step-by-step explanation:
Given
[tex]\frac{x}{3z}[/tex] = y - 2 ( multiply both sides by 3z to clear the fraction )
x = 3z(y - 2)

Is the equation y=4x proportional
which expression is equivalent to (3x+4)(7x-2)
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.

The correct statement about the math class is the the girls make up 8/15 of the class.
What are ratios?
Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).
Ratio of the number of girls in the class = number of girls in the class / sum of ratios
8 / (7 + 8 ) = 8 / 15

I hope this helps;) sorry if it dosen't
Answer:
The Answer Is 10
Step-by-step explanation:
The Total Strength = 40 Students
The Ratio Of Boys To Girls = 3:5
So, 3 + 5 = 8
Then, Divide 8/40 So That U Get The Number Then Multiply It With The Ratio.
•8/40 = 5
•5 × 3 = Boys Strength Which Is = 15
•5 × 5 = Girls Strength Which Is = 25

Please help! Simply the polonomials!
Answer:
1) 11x^3 - 6x - 3
2) 3x^3 + 4x^2 - 2x - 1
3) 9x^2 - 4
4) -4x^4 + 2x^3 - x^2
5) x^3 - 38x - 12
Step-by-step explanation:
1) (3x^4 + 5x^3 - 7x + 2) - (3x^4 - 6x^3 - x + 5)
Step 1: 3x^4 + 5x^3 - 7x + 2 - 3x^4 + 6x^3 + x - 5 (multiply the terms in the parenthesis by the constants, which are 1 and -1)
Step 2: 3x^4 - 3x^4 + 5x^3 + 6x^3 - 7x + x + 2 - 5 (reorganize the polynomial by exponential values (ex: x^4 before x^3 before x^1))
Step 3: 11x^3 - 6x - 3 (add like terms)
2) (3x^3 + 8x - 3) + (4x^2 - 10x + 2)
Step 1: 3x^3 + 8x - 3 + 4x^2 - 10x + 2 (multiply the terms in the parenthesis by the constants)
Step 2: 3x^3 + 4x^2 + 8x - 10x - 3 + 2 (reorganize the polynomial)
Step 3: 3x^3 + 4x^2 - 2x - 1 (add like terms)
3) (3x + 2)(3x - 2)
Step 1: 9x^2 - 6x + 6x - 4 (Use FOIL to multiply binomials, or multiply the first terms, outside terms, inside terms, then last terms)
Step 2: 9x^2 - 4 (add like terms)
4) -x^2(4x^2 - 2x + 1)
Step 1: (-x^2*4x^2) + (-x^2*(-2x)) + (-x^2*1) (multiply -x^2 by each term)
Step 2: -4x^4 + 2x^3 - x^2 (simplify; remember x^2 is the same as -1*x^2)
5) (x + 6)(x^2 - 6x - 2)
Step 1: ((x*x^2) + (x*(-6x)) + (x*(-2))) + ((6*x^2) + (6*(-6x)) + (6*(-2))) (multiply the first term in the binomial by each term in the trinomial, and do the same with the second term)
Step 2: x^3 - 6x^2 + 6x^2 - 2x - 36x - 12 (simplify and reorganize)
Step 3: x^3 - 38x - 12 (add like terms again)
