Which of the following ordered pairs
make this equation true?
y = 5x
B. (-10,-2)
A. (15,-3)
D. (2, 10)
C, (5, 1)
Answer:
D
Step-by-step explanation:
To solve this you can just plug in the x values into the equation and if the answer is correct the y value should be your answer
For example if we look at D
we can plug in 2 for y=5x and get 10
We can see that the y value in the ordered pair is also 10 making this the correct answer
kind of hard to explain if you have any questions leave a comment
Answer:
D
Step-by-step explanation:
y= 5x
10= 5(2)
10=10

y=7x+5
y=x+17
Answer:
(x, y) = (2, 19)
Step-by-step explanation:
7x + 5=x + 17
x=2
y=7*2+5
y=19
Please give brainlyist
Answer: (2, 19)
Step-by-step explanation:
There are three general ways to solve a system of equations:
- Substitution
- Elimination
- Augmented Matric
Since both given equations all have y isolated, substituting the value of y will be the most appropriate way here.
--------------------------------------------------------------------------------------------------------
Given
y=7x+5
y=x+17
Substitute y into the equations
7x+5=x+17
Subtract 17 on both sides
7x+5-17=x+17-17
7x-12=x
Subtract 7x on both sides
7x-12-7x=x-7x
-12=-6x
Divide -6 on both sides
-12/-6=-6x/-6
x=2
Substitute value into one of the equations
y=x+17
y=2+17
y=19
(2, 19)
Hope this helps!!

Based on their own blood types a couple has a 0.75 probability of having a child with type A blood. If the couple has 4 children, what is the probability that they will have 2 children with type A blood?
A. 0.07
B. 0.21
C. 0.56
D. 0.75
Answer:
B. 0.21
Step-by-step explanation:
https://stattrek.com/online-calculator/binomial.aspx
put in 75% for success rate
4 for the amount of trials because that is the total of kids the couple has
2 for number of successes for how many kids would get Type A blood
once calculated you get.21 or answer B

PLEASE HELP DUE VERY SOON!
Answer:
Yes. (see below)
Step-by-step explanation:
First, find the slope of the line. You can do that by using the slope formula:
y2 - y1
m = ----------
x2 - x1
Now, choose any two points from the line to plug in. I'm using the points (0, 3) and (2, 4).
4 - 3
m = ------
2 - 0
1
m = --- = 1/2
2
Now, to simplify your situation, you can use the slope-intercept formula. To use this, you first need to find the slope and y-intercept.
The y-intercept is where the line meets the y-axis, which is (0, 3), so the y-intercept is 3.
Now, plug them in:
y = mx + b
y = 1/2x + 3
To see if a specific point is on this line—which, in this case, is (20, 13), plug them in and simplify to see if it's true:
13 = 1/2 (20) + 3
13 = 10 + 3
13 = 13
This is true, so the point (20, 13) is on this line.

25 points. Which problem will graph as shown?
A) 3x - 5 ≥ -14
B) 3x - 5 ≤ -14
C) 3x - 5 > -14
D) 3x - 5 < -14
Answer:
D
Step-by-step explanation:
We can work backwards.
First, notice that we have an open circle. So, we do not have "or equal to." So, we can ignore A and B.
Our final answer is all values less than -3. So:
[tex]x<-3[/tex]
We can multiply both sides by 3:
[tex]3x<-9[/tex]
And then subtract 5 from both sides:
[tex]3x-5<-14[/tex]
So, the answer that matches this will be D.
Instead of working backwards, you can also just solve each inequality. Since we have an open circle, we only need to solve C and D. If we solve C, we get x > -3, and if we solve D, we get x < -3 (as desired). So, D matches the graph shown.

Answer:
b < -7 or b > 7
Step-by-step explanation:
b is surrounded by absolute value bars, which means that whether the value of b is negative or positive, the bars will make it positive. |b| is said to be greater than 7, so the value of b must be:
less than -7 (it can be -8, -9, -10, ...) because the absolute value bars will make it positive.
&
greater than 7 (it can be 8, 9, 10) because it will stay positive anyway.
Therefore, the second answer choice is correct.
I hope this helped! :)
