Find the solutions to the system; y=x^2-3x-1 and y=8x-1

PSYCHO15rus [73]

${x}^{2} - 3x - 1 = 8x - 1 \\ {x}^{2} - 11x = 0 \\ x(x - 11) \\ x = 0 \: or \: x = 11$

When x = 0,
$y = 8x - 1 \\ y = 0 - 1 \\ y = - 1$

When x = 11
$y = 8(11) - 1 \\ y = 87$
x = 0, y = - 1
x = 11, y = 87

Answer is B.

3x-7=4x+10 <br> show the steps pleeease

Fudgin [204]

Answer:

-17

Step-by-step explanation:

3x-7=4x+10

Add 7 to both sides & simplify

3x-7=4x+10

+7 +7

3x=4x+17

Subtract 4x from both sides & simplify

3x=4x+17

-4x -4x

-x=17

*Negative x equals -1*

Divide both sides by -1 & simplify

$\frac{-x}{-1} =\frac{-17}{-1}$

$x=-17$

What do the differences between the points (as shown on the graph) represent?

artcher [175]

The first one 7/2 represents the change in y over change in x.

For those kinds of questions I would refer to the change in y over change in x method.

Bullet 3 would work because 7/2 doesn’t result to 1. So that’s not the answer.

I hope that helps

Rudy invested $2460 in a money market account for 3 and 1/2 years. He earned $452 in simple interest. Which best represents the

antiseptic1488 [7]

Answer:

B. 5 and 1/4 percent

Step-by-step explanation:

Step one:

given

principal= $2460

time= 3 and 1/2 years= 3.5 years

SI= $452

Required

The rate

Step two:

we know that

SI= PRT/100

substituting our data we have

452= 2460*R*3.5/100

452=8610R/100

cross multiply

452*100= 8610R

divide both sides by 8610

45200/8610= R

R= 5.25%

R= 5 and 1/4 percent
