Find the missing value so that the line passing through the points has the given slope
(10,y) and (3,4) m= -2/7
Answer:
y = 2Step-by-step explanation:
Using slope formula and solving for y
m = (y2 - y1)/(x2 - x1)
-2/7 = (4 - y)/(3 - 10)-2/7 = (4 - y)/-72 = 4 - yy = 4 - 2y = 2Answer:
y = 2
Step-by-step explanation:
Using slope formula and solving for y
m = (y2 - y1)/(x2 - x1)
-2/7 = (4 - y)/(3 - 10)
-2/7 = (4 - y)/-7
2 = 4 - y
y = 4 - 2
y = 2
Please solve this question.(Quadratic equation)
Answer: 28
Step-by-step explanation:
Let x represent the digit in the tens place and y represent the digit in the ones place. xy → 10x + y
The square of the sum of the digits is 100.
EQ1: (x + y)² = 100 → x + y = 10
2 is subtracted from 3 times the number is the digits reversed.
EQ2: 3(10x + y) - 2 = 10y + x → 30x + 3y - 2 = 10y + x → 29x - 7y = 2
Solve the system of equations using the Elimination method:
EQ1: x + y = 10 → 7(x + y = 10) → 7x + 7y = 70
EQ2: 29x - 7y = 2 → 1(29x - 7y = 2 → 29x - 7y = 2
36x = 72
÷36 ÷36
x = 2
Substitute x = 2 into either of the equations to solve for y.:
EQ1: x + y = 10
2 + y = 10
y = 8
The digit is: 28

1. Given x=5, plug x into y=10x-2.
a. 38
b. 12.
C. 13
d. 48
Answer:
D. 48
Step-by-step explanation:
y=10x-2 is our equation
If x is 5, then multiply 10 by 5. You get 50.
Subtract 2 from that. You get 48.
Answer:
D, 48
Step-by-step explanation:
Given x=5, plug x into y=10x-2
First you should plug the given x into the x in the equation. And put () around it.
y=10(5)-2
Now you multiply 10 by 5 and you get 50.
y=50-2
Now the last step is to subtract 2 from 50 which you will end up getting y=48. So the answer is y=48 which is letter D.
y=48
A Pattern has 5 blue triangles to every 80
yellow triangles, what is the ratio of blue
triangles to all triangles?
Answer:
5:80, there are only 2 numbers
Step-by-step explanation:
The ratio of blue triangles to all triangles is 1 : 17.
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
Given that;
A Pattern has 5 blue triangles to every 80 yellow triangles.
Here, Number of blue triangles = 5
Number of all triangles = 5 + 80
= 85
Thus, The ratio of blue triangles to all triangles is,
⇒ Number of blue triangles : Number of all triangles
⇒ 5 : 85
⇒ 1 : 17

The function has no intercepts.
Option C is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The x-intercept is the point on the x-axis when y= 0.
The y-intercept is the point on the y-axis when x= 0.
We see that,
There is no point on the x-axis or y-axis that the graph is touching.
So,
We can say that,
There are no x-intercepts and y-intercepts.

Mario walked 7422 steps one day then he walks 5570 stops the next day. which calculation can be used to find the total number of steps Mario walked two days
Answer:
A caucluation he can use is adding, just add 7422 and 5570 and you should get your answer.
Step-by-step explanation:
Mario walked total 12992 steps.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Mario walked 7422 steps one day
and, he walks 5570 stops the next day.
So, the total number of steps
= 7422 + 5570
= 12992 steps
Hence, Mario walked total 12992 steps.

b = 92 degrees (choice B)
c = 92 degrees (choice D)
d = 92 degrees (choice F)
================================================
Explanation:
Angles a and b are supplementary because they form a straight angle when combined. The two angles add to 180
a+b = 180
88+b = 180 ... plug in a = 88
b = 180-88 ... subtract 88 from both sides
b = 92
------------
Angles b and c are congruent because they are alternate interior angles. Alternate interior angles are congruent when dealing with parallel lines.
Since the diagonal entrance ramps are parallel, this means the corresponding angles c and d are congruent.
Since b = 92, this means c = 92 and d = 92 also.

What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
A mathematical phrase in which the sides are not equal is referred to as being unequal.
Given the inequality,
v +8 < 3
Adding -8 on both sides
v + 8 - 8 < 3 - 8
v < -5
Or,
8v <-40
Divide 8 on both side
v < -5

Step-by-step explanation:
A kindergarten teacher bought $21 worth of stickers and cardstock for his class. The stickers cost $1.50 a sheet and the cardstock cost $3.50 per pack. The equation 1.5s+3.5c=21 represents the relationship between sheets of stickers, s, packs of cardstocks, c, and the dollar amount a kindergarten teacher spent on these supplies.
1. Explain how we can tell that this graph represents the give equation.
2. What do the vertical and horizontal intercepts, (0,6) and (14,0), mean in this situation?
Answer:
Step-by-step explanation:
Teacher bought $21 worth of stickers and cardstock for his class.
Cost of stickers = $1.50 per sheet
Cost of 's' sheets = $1.5s
Cost of cardstock = $3.50 per pack
Cost of 'c' packs = $3.5c
Equation representing the relationship between sheet of stickers and packs of cardstocks will be,
1.5s + 3.5c = 21
3.5c = -1.5s + 21
1). [tex]c=-\frac{3}{7}x+6[/tex]
y-intercept of the line → (0, 6)
x-intercept of the line → (14, 0)
Therefore, equation of the line represents the line on the graph.
2). Vertical intercept (0, 6) represents that he can purchase maximum 6 packs of cardstock with $21.
Similarly, horizontal intercept (14, 0) represents that he can purchase maximum 14 sheets of stickers with $21.
