VvLabel Slope and Y-intercept in each Equation

2 answers:

5 0

Hey if this helps anyone who reads this if that is in standard form do the opposite of A over B reduce that if you can(that gets you your slope), and then do C over B and then divided that (that gets you your Y-intercept)

This way is so much faster and so much easier than the long way

1- slope is 4 y intercept 0,2

2- slope is 6 y intercept 0,5

3- slope is 2 y intercept is 0,5

4 -slope is 1 y intercept is 0, 3/4

5- slope is 10 y intercept is 0,3

6- slope is 4 y intercept is 0,1/2

7- slope is 4 y intercept is 0, 3/2

8- slope is 1 y intercept is 0,2

A rectangle has a perimeter of 30 feet and an area of 50 square feet. What are the dimensions of the rectangle?

REY [17]

Perimeter (p) = 2×length (l) + 2×width (w)
p = 2l+2w
area (a) = l×w, so solve for one (I'll use l):
$a = l \times w \\ l = a \div w \\ p = 2l + 2w = 2(l + w)$
since p = 30, and a = 50, substitute the "a÷w" in for l in the perimeter equation:
$p = 2(l + w) = 2((a \div w) + w) \\ = 2((a \div w) + ( {w}^{2} \div w)) \\ p= 2((a + {w}^{2}) \div w$
Now plug in p and a values:
$p= 2((a + {w}^{2}) \div w) \\ 30 = 2((50 + {w}^{2}) \div w) \\ 30 \div 2 = (50 + {w}^{2}) \div w \\ 15w = 50 + {w}^{2}$
$15w = 50 + {w}^{2} \\ {w}^{2} - 15w + 50 = 0 \\ (w - 5)(w - 10) = 0$
therefore width can be either 5 or 10 (but not both), so let's plug in:
l = a÷w = 50÷5 = 10
So if w = 5, then l = 10

D) 5 feet, and 10 feet

Which expression is not equivalent to −4x3+x2−6x+8?

Gekata [30.6K]

The expression which is not equivalent to the provided expression is expression number 1, x²(-4x+1)-2(3x-4).

<h3>What is the equivalent expression?</h3>

Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.

The expression given in the problem is

f(x)=-4x³+x²-6x+8

The option given as,

(1) x² (-4x+1)-2(3x-4)
(2) x(-4x²- x + 6) + 8
(3) -4x³ + (x - 2)(x - 4)
(4) -4(x³ - 2) + x(x - 6)

From the given expression, if we take out <em>x </em>from the first three terms, it looks like option 2.

f(x)=-4x³+x²-6x+8

f(x)=x(-4x²+x-6)+8

From the given expression, if the last three terms factored, it looks like option 3.

f(x)=-4x³+x²-6x+8

f(x)=-4x³+x^2-4x-2x+8

f(x)=-4x³+x(x-4)-2(x-4)

f(x)=-4x³+(x-4)(x-2)

Rearrange the given expression, and make it looks like option 4.

f(x)=-4x³+x²-6x+8

f(x)=-4x²+8+x²-6x

f(x)=-4(x³-2)+x(x-6)

Thus, the expression which is not equivalent to the provided expression is expression number 1, x²(-4x+1)-2(3x-4).

Find the value of x for which a || b.<br> a<br> (7x + 2)<br> b<br> (8x – 14)

Alika [10]

Answer:

x = 16

Step-by-step explanation:

We know that line a and b are parallel so they each have the same slope therefore, (7x + 2) = (8x - 14).

First we have so isolate a number value and x.

So we subtract 7x from 8x, which looks like:

2 = (x - 14)

Then we have to get that -14 to the other side, so we add and that looks like:

16 = x

Therefore, we have our answer, x = 16.
