Answer:

$x = 8 \\ y = 9$

Step-by-step explanation:

$2y = x + 10 \\ y = 2x - 7 \\$

since they gave us a value for y in the second equation, we can input it into the first equation. so...

$2(2x - 7) = x + 10 \\ 4x - 14 = x + 10 \\ 4x - x = 10 + 14 \\ 3x = 24$

$\frac{3}{3} x = \frac{24}{3} \\ x = 8$

Since x is 8 we can find y by substituting 8 for x

$y = 2x - 7 \\ y = 2(8) - 7 \\ y = 16 - 7 \\ y = 9$

Answer:

17 degrees

Step-by-step explanation:

So to find the answer you need to subtract. If the temp went down 22.1 degrees and it is -5.1 degrees you will subtract 22.1 - 5.1. This equals 17 degrees. You know the answer is correct because you can check your answer by adding: 5.1 + 17 = 22.1. We are disregarding the negative sign.

The curve with equation y = f ( x ) is stretched so that the point (-3,-5) moves to the point (-3,-10). State in terms of f ( x

Leviafan [203]

Answer:

The transformed function is $g(x) = 2\cdot f(x)$ , $\forall\,x \in \mathbb{R}$ .

Step-by-step explanation:

Let be $f(x)$ and $g(x)$ continuous functions in x. In this case, the stretch factor consist on multiplying $f(x)$ by a scalar factor, so that:

$g(x) = k \cdot f(x)$ , $\forall\, k\in \mathbb{R}, k \neq 0$

The stretch factor is:

$k = \frac{g(x)}{f(x)}$ , $\forall\, x \in \mathbb{R}$

If $f(-3) = -5$ and $g(-3) = -10$ , then:

$k = \frac{g(-3)}{f(-3)}$

$k = \frac{-10}{-5}$

$k = 2$

The transformed function is $g(x) = 2\cdot f(x)$ , $\forall\,x \in \mathbb{R}$ .

Answer:

y = 3000x + 40000
a) the base salary of the salesperson
a) the commission per subscription

Step-by-step explanation:

Slope intercept form is found by [ y = mx + b ] where m = slope and b = y-intercept. We are given that a salesperson gets $40000 as a base salary. Since this value doesn't change it is the starting value, in other words the y-intercept. The salesperson also gets $3000 for every subscription they sell. Since this amount grows at a constant rate, that is the slope. Now, we can write the slope intercept form of [ y = 3000x + 40000 ].

Best of Luck!

lora16 [44]

Answer:

D, 122°F

Step-by-step explanation:

°F = 9/5°C + 32

°F = 9/5(50) +32

°F = 90 + 32

°F = 122
