Correct question is;
Joe had a summer job that pays $7.00 an hour and he worked between 15 and 35 hours every week. His weekly salary can be modeled by the equation: S = 7h, where S is his weekly salary and h is the number of hours he worked in a week.
What is the reasonable Domain and Range?
Answer:
Domain is: 15 ≤ x ≤ 35
Range is: 105 ≤ x ≤ 245
Step-by-step explanation:
We are told that Joe works between 15 and 35 hours every week.
This means that he works at least 15 hours or at most 35 hours a week.
Thus, domain is; 15 ≤ x ≤ 35
We are told that his weekly salary can be modeled by the equation: s = 7H
Where s is salary and H is number of hours worked per day.
Thus;
Lower range is; s = 7 × 15 = $105
While higher range is; s = 7 × 35 = $245
Thus, range is 105 ≤ x ≤ 245

Simplify the following expression: (-1)(-7)(4) (1 point)
12
28
-12
-28
Answer:
28
Step-by-step explanation:
(-1)(-7)(4)
Let’s rephrase this
(-1) * (-7) * 4
Multiple in order
(-1) * (-7) = 7
A negative times a negative equals a positive.
7 * 4= 28

Find the area. Simplify your answer.
Answer: 1.5x²
Step-by-step explanation:
Rule: To find the area of a triangle, multiply the base times one side, then divide the product by 2.
Step 1: Find the length of the left side using the pythagorean theorem.
a^2 + b^2 = c^2.
x^2 + 2x^2 = 3x^2
√3x² = 3x
Step 2: Multiply the base times the hypotenuse.
x * 3x = 3x²
Step 3: Divide by two
3x²/2 = 1.5x²
Find cosα given that sinα = 5/13 and α is in quadrant II
Answer:
cos α = - [tex]\frac{12}{13}[/tex]
Step-by-step explanation:
Since α is in second quadrant then cosα < 0
Using the identity
sin²α + cos²α = 1 then
cosα = - [tex]\sqrt{1-sin^2\alpha }[/tex]
= - [tex]\sqrt{1-(\frac{5}{13})^2 }[/tex]
= - [tex]\sqrt{1-\frac{25}{169} }[/tex]
= - [tex]\sqrt{\frac{144}{169} }[/tex]
= - [tex]\frac{12}{13}[/tex]

Answer: the pre image is FGH
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
The triangle was translated 4 units down.
It can not be A, because it would have needed to be translated up 4 units.
It can't be C, because they are not both images, one is the starting image or the pre-image and the other is after the translation or the image.
D is incorrect because it con be determined.
Hope this helps :-)
Write a proportion for each situation. Then solve
c. 25 yards in 2 1/2 seconds 100 yards in y second
d. 480 heartbeats in 4 minutes z heartbeats in 1 minute
Answer:
c. x = 10d. z = 120Step-by-step explanation:
Given proportions
Equations as per ratio and solution for each
c. ..................................
25 ÷ 2 1/2 = 100 ÷ x25 ÷ 5/2 = 100 ÷ xx = 100×5/2÷25x = 10100 yards in 10 seconds
d. ..................................
480 ÷ 4 = z ÷ 1120 = zz = 120120 heartbeats in 1 minute
Answer:
c. y = 10 secs.d. z = 120 heartbeatsStep-by-step explanation:
c. ratio and proportion:
25 yards = 100 yards
2.5 sec. y sec.
cross multiply:
100 (2.5) = 25 (y)
simplify:
y = 250 / 25
y = 10 secs.
------------------------------------------
d. ratio and proportion:
480 heartbeats = z heartbeats
4 mins. 1 min.
cross multiply:
4 (z) = 480 (1)
simplify:
z = 480 / 4
z = 120 heartbeats

0 -2.02a
O Type here to search
OBI
Answer:
-0.55 + 0.53a
Step-by-step explanation:
-0.55 – 0.47a + a
To find an expression equivalent to this, we must simplify the equation to a reasonable extent;
-0.55 – 0.47a + a
= -0.55 + 0.53a
= 0.53a - 0.55
The expression equivalent to the given one is -0.55 + 0.53a or 0.53a - 0.55

I have sent a photo im not sure if u can see it
Answer:
That would be (-5,5)
Step-by-step explanation:
Unless I saw the photo wrong, you start at the coordinates (-3,-1). You move left 2 units to get to (-5,-1). Then you move 6 units up. That will get you to (-5,5).

Find the equation of the linear function represented by the table below in slope-
intercept form.
y=Mx+B
Answer:
y = x + 4
Step-by-step explanation:
Let the equation of the linear function represented by the table is,
[tex]y-y_1=m(x-x_1)[/tex]
where m = slope of the line
And this line passes through the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Slope of the given line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
From the given table two points lying on the function are (-4, 0) and (1, 5).
Slope 'm' = [tex]\frac{5-0}{1+4}[/tex] = 1
Therefore, equation of the linear function passing through (1, 5) and slope 1 will be,
y - 5 = (x - 1)
y = x + 5 - 1
y = x + 4
