j(x)=−45x+7; j(x)=−5
Answer:
x = 4/15
Step-by-step explanation:
Step 1: Define
j(x) = -45x + 7
j(x) = -5
Step 2: Substitute and Evaluate
-5 = -45x + 7
-12 = -45x
x = 4/15
help find the slope of the line
Answer:
-3/5
Step-by-step explanation:
When finding the slope, think of it as rise/run.
Rise= up/down
run=left or right
So looking at the line, it is pointing towards -inf so the slope is negative
Then we look at 2 points.
i.e. (0,2) and (-5,5) and do the rise over run technique (or just subtract) and you get your answer!
6≥−6(a+2) solve and find the awnser
Answer:
[tex] - 3 \geqslant a[/tex]
Step-by-step explanation:
[tex]6 \geqslant - 6(a + 2)[/tex]
distribute -6 inside the parentheses
[tex]6 \geqslant - 6a - 12[/tex]
add 12 to both sides
[tex]18 \geqslant - 6a[/tex]
divide by -6 to isolate the variable
[tex] - 3 \geqslant a[/tex]
Answer:
-3<=a
Step-by-step explanation:
1. Get the -6 away, so multiply everything by -6. 6*-6 >= -6*-6(a+2)
2. This becomes -1 <= a+2 Since if you multiply or divide anything by a negative number, you have to reverse the inequality sign.
3. Subtract 2 to get a by itself -1-2 >= a
4. This becomes -3 >= a which is the right answer.
(Just so you know >= and <= means less than or equal to and more than or equal to.)

Raina corre 7 millas en 50 minutos. A esta misma tasa, ¿qué distancia en millas correría en 75 minutos?
Responder:
10.5 millas
Explicación paso a paso:
50 / 7 = 0.14
0.14 * 75 = 10.5
Espero que esto ayude :)
Given parameters:
Distance covered by Raina = 7 miles
Time taken = 50 minutes
Unknown:
Distance covered in 75 minutes = ?
To solve this problem, we have to find the speed of Raina during the first 50 minutes.
Speed is the distance covered with time.
Speed = [tex]\frac{distance}{time taken}[/tex]
Input the parameters and solve;
Speed = [tex]\frac{7 miles }{50 minutes}[/tex] = 0.14miles/min
Now, to find the distance covered in the second run;
Distance = speed x time taken
= 0.14miles/min x 75min
= 10.5miles
The distance covered in miles is 10.5miles

Answer:
candy 7
packs 5
Step-by-step explanation:
Answer:
Option A!
Step-by-step explanation:
Hey there!
To figure out the ratio of candies per packs, we divide 21 (candy) by packs (3) and we get 7. This means that there are 7 candies per pack! So, in 1 pack, there are 7 candies and when there are 35 candies, we divide 35 by 7 and get 5.
So, in one pack there are 7 candies and there are 35 candies in 5 packs.
Option A. Candy: 7 Packs:5

I need help graphing 2x - 6y = 42 I'm just really lazy
Answer:
We can use slope intercept form to get the points needed. Y= -7+1/3x The points are (0,-7) and (3,-6)
Step-by-step explanation:
Subtract 2x from the left side and place it over to the right side with the 42. Now we have -6y= 42-2x. From here we divide by -6 and we get y= -7+1/3x. We know that are slope is 1/3 which the one is the rise and the 3 is the run. We also know that our y intercept is -7. We plot the points at (0,-7) and (3,-6)

1.) Which of the following equations is not a linear equation?
A) y = -4
B)X 3 = 1
C) 2x -4y =1
D) y= X - 2
2.) Find the value of y that makes the equation y= -x + 5 true, when x =-4
A.) -1
B.) 2
C.) 1
D.) 9
3.) Find the value of y that makes the equation y= x + 1/4 true, when x = - 1/4.
A.) -4
B.) 0
C.) 1
D.) 4
Answer:
1) B
2) D
3) B
Step-by-step explanation:
For question 1:
Assuming that option B is [tex]x^3=1[/tex], it is not a linear function.
Linear functions have equations that do not have exponents.
For question 2:
[tex]y=-(-4)+5\\\\y=4+5\\\\\boxed{y=9}[/tex]
The option is D.
For question 3:
[tex]y=x+\frac{1}{4}\\\\ y=-\frac{1}{4}+\frac{1}{4}\\\\ \boxed{y=0}[/tex]
The option is B.
Hope this helps.

What is the slope of the line passing through the points (-3, 4) and (2, – 1)?
Answer:
m=-1 or -1/1 (same thing)
Step-by-step explanation:
(y2-y1/x2-x1)
(-1-4)/(2-(-3))=-5/5=-1
Answer:
-1
Step-by-step explanation:
The slope of a line can be written as [tex]\frac{\triangle{y}}{\triangle{x}}[/tex] or [tex]\frac{y_2 - y_1}{x_2-x_1}[/tex]. Plugging in the values gives us [tex]\frac{-1 - 4}{2 - (-3)} = \frac{-5}{5} = \boxed{-1}[/tex]

While shopping at a music store, Rick bought 7 CD’s, all at the same price. The tax was $6.50 and the total was $66.00. What was the price of each CD?
Answer:
$8.50
Step-by-step explanation:
Subtract the tax from the total price:
66 - 6.50
= 59.5
Then, divide this by 7 to find the cost of each CD:
59.5/7
= 8.5
So, the price of each CD was $8.50
Answer:
8.50
Step-by-step explanation:
66-6.50=59.50
59.50 divided by 7 =8.50
