Answer:

slope: 3
y-intercept: 0

Step-by-step explanation:

The multiples of 3 satisfy the equation ...

y = 3x

where x is the multiplier and y is the multiple.

Compared to the slope-intercept form ...

y = mx + b . . . . . . . . . slope: m, y-intercept: b

we see that m = 3 and b = 0.

The slope is 3; the y-intercept is zero.

Choose the expression that represents a quadratic expression. 9x − 2 5x2 + 9x − 1 −2x3 + 8x2 − 7x + 1 x4 − 12x3 + 8x2 − 7x + 1

Answer:

$5 {x}^{2} + 9x - 1$

Step-by-step explanation:

A quadratic expresion is of the form

$a {x}^{2} + bx + c$

where

$a \ne0$

The give options are:

$9x-2$

$5{x}^{2}+9x - 1$

$-2x^3+8 {x}^{2} -7x +1$

$x^4-12x^3+8 {x}^{2} -7x +1$

From the given options, the only expression which is quadratic is

$5 {x}^{2} + 9x - 1$

where a =5, b=9 and c=-1

Therefore the correct choice is the second option.

One number is 5 more than the other. Their sum is 33. Find the numbers.

dimaraw [331]

Answer:

19,14

Step-by-step explanation:

x=5+y

x+ y= 33

we will solve using substitution

(5+y) +y= 33

5+y+y=33

5+2y=33

subtract 5 from both sides

2y=28

y=14

We got y now we will find what x is

for this, we will substitute y's value (14) into the first equation

x=5+(14)

x=19

we got x too
