What is the slope of this line −4x+7=2y−3

1 answer:

3 0

First, change this equation to y-intercept form:
-4x+7=2y-3
2y = -4x+10
y= -2x + 5
The slope is -2, which is the coefficient for x in y-intercept form.

Omae wa sinderou nani (questions in the image btw)

Korvikt [17]

Let $a$ be the number of hours worked at Job A and $b$ the number of hours at Job B. Then

$a+b=30$

and

$7.5a+8b=234.50$

From the first equation,

$b=30-a$

and substituting this into the second gives

$7.5a+8(30-a)=234.50\implies-0.5a+240=234.50$

$\implies0.5a=5.50$

$\implies\boxed{a=11}$

Graph the solutions of the inequality

Fiesta28 [93]

Answer:

The graph in the attached figure

Step-by-step explanation:

Graph the solution of the inequality

$t\leq -4$

we know that

The solution is the interval ---> (-∞,-4]

All real numbers less than or equal to -4

In a number line the solution is the shaded area at left of t=-4 (closed circle, because the number -4 is included in the solution))

using a graphing tool
