Answer: A
Explanation:
Basically, it points out the value of x, meaning you have to define x as that number so you plug -4 for x.
How I plugged it in: 3(-4)^2-5(-4)+3

5x + 7y = 17 x + 4y = 19

REY [17]

<h2>Answer:</h2>

5x + 7y = 17 ....(1)

x + 4y = 19 .....(2)

From equation 2

x + 4y = 19

x = 19 - 4y

Putting the value of x in Equation (1)

5(19 - 4y) + 7y = 17

95 - 20y + 7y = 17

- 20y + 7y = 17 - 95

-13y = -78

y = $\frac{78}{13}$

y = 6

Now, putting the value of y in equation (2)

x + 4y = 19

x + 4(6) = 19

x + 24 = 19

x = 19 - 24

x = -5

Therefore, the value of y is 6 and value of x is -5

Carlos has used 40 cell phone minutes each day for one full week. His cell phone plan allows for a total of 320 minutes per week

sammy [17]

40 minutes*7 days of the week= 280 minutes a week. So, 320-280= 40 minutes left over. 40:320= 1:8. You were correct!

What is the volume of the square pyramid with base edges 18 m and slant height 15 m

vlada-n [284]

check the picture below.

so it has a base of 18x18 and a height of that much.

$\bf \textit{volume of a pyramid}\\\\ V=\cfrac{1}{3}Bh~~ \begin{cases} B=area~of\\ \qquad its~base\\ h=height\\ ------\\ B=\stackrel{18\times 18}{324}\\ h=12 \end{cases}\implies V=\cfrac{1}{3}(324)(12)\implies V=1296$
