Answer:

(0, 0) and (3, 0)

Step-by-step explanation:

Zeros of any equation means, value of variable x at y = 0.

Given quadratic equation is,

y = -x(x - 3)

For y = 0,

-x(x - 3) = 0

x = 0

And (x - 3) = 0

x = 3

Therefore, x-intercepts of the given quadratic equation will be,

x = 0, 3

Points showing the x-intercepts will be,

(0, 0) and (3, 0)

Kira, goran, & joe sent a total of 90 text messages during the weekend. Goran sent 5 fewer messages than Kira. Joe sent 3 ti

MissTica

Answer:

Kira sent 19 text messages, Goran sent 14 text messages and Joe sent 57 text messages.

Step-by-step explanation:

Let be "k" the number of text messages that Kira sent during the weekend, "g" the number of text messages that Gora sent during the weekend and "j" the number of text messages that Joe sent during the weekend.

We know know that they sent a total of 90 text messages then:

$k+g+j=90$

Goran sent 5 fewer messages than Kira. This is:

$g=k-5$

And Joe sent 3 times as many messages as Kira. Then:

$j=3k$

The steps to solve this are:

- Substitute the second equation and the third equatio into the first equation and then solve for "k":

$k+(k-5)+(3k)=90\\\\5k-5=90\\\\5k=90+5\\\\k=\frac{95}{5}\\\\k=19$

- Substitute this value into the second equation to find "g":

$g=19-5=14$

- Substitute the value of "k" into the third equation to find "j":

$j=3(19)=57$

FIND THE SLOPE <br> please explain me how to do it

natka813 [3]

Answer:

slope = - 1

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 4, 7) and (x₂, y₂ ) = (0, 3) ← 2 ordered pairs from the table

m = $\frac{3-7}{0+4}$ = $\frac{-4}{4}$ = - 1
