What is the solution to the inequality?

What is the slope of the line which passes through (4, 7) and (2, 3)? (5 points)

Basile [38]

Answer:

slope = 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (4, 7)

m = $\frac{7-3}{4-2}$ = $\frac{4}{2}$ = 2

12. Answer: 2130

Step-by-step explanation:

T = -0.01y + 10.6

9.2 = -0.01y + 10.6

-10.6 -10.6

-1.4 = -0.01y

÷-0.01 ÷-0.01

140 = y

"y" represents the number of years after 1990

1990 + 140

= 2130

13. Answer: -0.0036° per foot

Step-by-step explanation:

Since the relationship is linear, then we can set up the values as x, y coordinates and use the slope formula to find the rate of degrees over feet.

(6562, 63) and (16405, 28)

rate = $\frac{28 - 63}{16405-6562}$

= $\frac{-35}{9843}$

= $\frac{-0.0036}{1}$

14. Answer: $0.28 per kWh

Step-by-step explanation:

Same reason as #13

(200, 55) and (500, 140)

rate = $\frac{140-55}{500-200}$

= $\frac{85}{300}$

= $\frac{0.28}{1}$

Two identical jars are filled with equal numbers of marbles. The marbles are colored red or white. The ratio of red to white mar

IrinaK [193]

Let $a=$ the number of white marbles in Jar 1
Let $b=$ the number of white marbles in Jar 2
Total number of white marbles is $a+b=90$

Jar 1 has $a$ white marbles and $7a$ red marbles so $8a$ marbles total
Jar 2 has $b$ white marbles and $9b$ red marbles so $10b$ marbles total
Since both jars have equal amounts of marbles, $8a=10b$

We have a system of equations:
$a+b=90$
$8a=10b$

The number of red marbles in Jar 2 is $9b$ so we solve for $b$

$8a=10b$
⇒ $a=\frac{5}{4}b$
⇒ $\frac{5}{4}b+b=90$
⇒ $\frac{9}{4}b=90$
⇒ $b=40$
Number of red marbles in Jar 2 is $9b=360$

So there are 360 red marbles in Jar 2.
