What is the intercept of -3x + 4y = 24

1 answer:

7 0

X-intercept:
-3x + 4y = 24

Sub y = 0

-3x + 4(0) = 24

-3x + 0 = 24

-3x = 24

x = -8

y-intercept:
-3x + 4y = 24

Sub x = 0

-3(0) + 4y = 24

0 + 4y = 24

4y = 24

y = 6

Hope it helps :)

Which is a possible expression for the series

Anvisha [2.4K]

Without considering the sign:

It's sigma(1 to 5, 5k+2)

Since the first item is minus, you simply add (-1)^k

So it's sigma(1 to 5, (-1)^k * (5k+2)

I choose A

What is the slope-intercept form equation of the line that passes through (5,7) and (8,22)

JulsSmile [24]

$\bf (\stackrel{x_1}{5}~,~\stackrel{y_1}{7})\qquad(\stackrel{x_2}{8}~,~\stackrel{y_2}{22})\\\\\\ slope = m\implies\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{22-7}{8-5}\implies \cfrac{15}{3}\implies 5\\\\\\ \begin{array}{|c|ll}\cline{1-1}\textit{point-slope form}\\\cline{1-1}\\y-y_1=m(x-x_1)\\\\\cline{1-1}\end{array}\implies y-7=5(x-5)\\\\\\y-7=5x-25\implies y=5x-18$

the calorie cafe is known for their hotdogs and burgers. the number of calories in a burger is 220 more than the number of calor

meriva

Answer:

Number of calories in burger = 620 calories

Number of calories in hotdog = 400 calories

Step-by-step explanation:

Number of calories in burger = x

Number of calories in hotdog = y

y = x - 220

x + 2y = 1,420

Substitution:

x + 2 * (x - 220) = 1,420

x + 2x - 440 = 1,420

3x = 1,420 + 440

x = 1,860 / 3

x = 620 calories

y = x - 220

= 620 - 220

= 400 calories
