Im guessing its telling you to solve using substitution ?
Well your lucky, most of the work is already done :D
you know y=x-7 , so just replace y with (x - 7) in the other equation
4x - 7(x-7) = 10
4x - 7x + 49 = 10
-3x = -39
x = 13
Now just plug X in the original equation to fine Y
y = x - 7
y = 13 - 7
y = 6
so the solution would be
(13,6)

Answer: The Answer is B
Step-by-step explanation:
i need help with the last two. I forgot the formula and wondering if you will help me find which one is and isnt a triangle
Answer:
3. D) 26, 7, 31
4. B) 6, 34, 27
Step-by-step explanation:
Both #3 and #4 use the same strategy: the two shorter sides' sum has to be greater than the longer side.
#3:
2 + 8 is 10, which is less than 13. So A wouldn't form a triangle.
12 + 22 is 34, which is the length of the longer side. So B wouldn't form a triangle either.
14 + 18 is 32, which is less than 40. So C wouldn't form a triangle.
7 + 26 is 33, which is greater than 31. So D would form a triangle.
D. 26, 7, and 31 are the only lengths of the ones shown that form a triangle.
#4:
17 + 18 is 35, which is greater than 19. So A would form a triangle.
11 + 22 is 33, which is greater than 25. So C would also form a triangle.
5 + 18 is 23, which is greater than 20. So D would form a triangle.
6 + 27 is 33, which is less than 34. So B wouldn't form a triangle.
B. 6, 34, and 27 are the only lengths of the ones shown that don't form a triangle.

Write the slope-intercept form of the line with the given slope and point.
m = -2; (5, 1)
Answer:
y = -2x + 11
Step-by-step explanation:
If you already have the slope, all you need to do is find the y-intercept.
y = -2x + b
1 = -2(5) + b
1 = -10 + b
11 = b
The equation is y = -2x + 11

it's all on the picture please answer
HELP NEEDED PLEASE!!!! This math question confuses me. I thought the line didn't pass through any other point but I cant figure it out so please help me!
Answer:
B
Step-by-step explanation:
So wiggly, remember that slope is change in y/change in x, or in simpler terms, y/x. Thinking of this, y/x must simplyfy to -3. Or, you can think of it as -3/1.
So know that we have rewrote this as a slope of -3/1, lets use it. Where do we start? Well, we must start at point A, which is at 2 x and 7 y.
Now, going to the RIGHT(+1x) and going DOWN(-3y) we will go from 2x and 7y to 3x and 4y.
Are we on a point yet? Nope, lets do this again.
Now going to RIGHT again(+1x) and going DOWN again(-3y) we will go from 13x and 4y to 4x and 1y.
Are we on a point yet? Still no, lets try this one more time.
Now going to RIGHT again(+1x) and going DOWN again(-3y) we will go from 4x and 1y to 5x and -2y.
Are we on a point? YUP. We cna see that point B is at 5x and -2y.
Hope you get it right ;)

Answer:
Step-by-step explanation:
Ok so for question one we use the Pythagorean theorem, which is a^2+b^2=c^2
a is the shortest leg, b is the leg that is not the hypotenuse. and c is the hypotenuse which is the opposite leg to the right angle.
Question 1: a=9,b=12,c=x
(9)^2+(12)^2=(x)^2
81+144=(x)^2
225=(x)^2
x=15
Question 2: a=10,b=24,c=x
(10)^2+(24)^2=(x)^2
100+576=(x)^2
676=(x)^2
x=26
Question 3: a=3,b=7,c=x
(3)^2+(7)^2=(x)^2
9+49=(x)^2
58=(x)^2
x=root58, or 7.615773
Question 4: a=6,b=x, c=10
(6)^2+(x)^2=(10)^2
36+(x)^2=100
Subtract 36 from both sides
(x)^2=64
x=8
Question 5: a=6,b=x, c=24
(6)^2+(x)^2=(24)^2
36+(x)^2=576
Subtract 36 from both sides
(x)^2=540
x=6root15, or 23.2379
Question 6: a=1, b=1, c=x
(1)^2+(1)^2=(x)^2
1+1=(x)^2
2=(x)^2
x=root2, or 1.414213562
Question 7: a=8, b=x, c=21
(8)^2+(x)^2=(21)^2
64+(x)^2=441
Subtract 64 from both sides
(x)^2=377
x=root377, or 19.41648784
Question 8: a=24, b=x, c=30
(24)^2+(x)^2=(30)^2
576+(x)^2=900
Subtract 576 from both sides
(x)^2=324
x=18
Question 9: a=5,b=9, c=x
(5)^2+(9)^2=(x)^2
25+81=(x)^2
106=(x)^2
x=root106, or 10.29563014
Question 9 Part B: a=3, b=5, c=y
(3)^2+(5)^2=(y)^2
9+25=(y)^2
34=(y)^2
root34, or 5.830951895=y
Which expression below has a coefficient, a product, and a sum? A. (3 / 3) + (6 – 2) B. (3/n) + (6 + 2) C. 3n(6) + (6 – 2) D. n + (6 – 2)
Answer:
C. 3n(6) + (6 – 2)
Step-by-step explanation:
C. 3n(6) + (6 – 2) has a coefficients, a product and a sum
Coefficients = 3
3 is the coefficients of n
Product means multiplication
3n(6) = product of 3n and 6
Sum means addition(+)
3n(6) + (6 – 2) = the addition of 3n(6) and (6 - 2)
3n(6) + (6 – 2)
= 18n + (4)
= 18n + 4

Mr. Tan bought a mobile phone at a discount of 25 %. The original price of mobile phone was of $400. How much did he pay for the mobile phone.?
Answer:
$300
Step-by-step explanation:
$400 is 100% of the price
25% is a quarter of 100%
A quarter of 400 is 100 so the discount was $100
400-100 =300

Zeke earned 23 extra credit points. Sofia earned e fewer extra credit points than Zeke. Write
an expression that shows how many extra credit points Sofia earned.
Answer:
s = 23 - e
Step-by-step explanation:
In this expression, s is equal to the amount of extra credit Sofia earns. She earns e less points than the 23 points Zeke earns.
So, s (Sofia's points) = 23 (Zeke's points) - e (the difference in points).
The expression is s = 23 - e.
Good luck ^^

The sum of three numbers is 235. The second number
is 15 more than the first number, and the third number
is 8 times the first number. Find the second number.
Answer:
37
Step-by-step explanation:
x = 1st number
y = 2st number
z = 3rd number
x + y + z = 235
y = x + 15
z = 8x
x + x + 15 + 8x = 235
10x = 220
x = 22
y = 37
z = 176
The second number is 37.
Given that,
The sum of three numbers is 235. The second number is 15 more than the first number, and the third number is 8 times the first number.Here we assume the first number be x, second number be y, and third number be z.Based on the above information, the calculation is as follows:
x + y + z = 235
y = x + 15
z = 8x
Now
x + x + 15 + 8x = 235
10x = 220
x = 22
So,
y = 22 + 15
= 37

One angle of a triangle measures 95° the other two angles are in a ratio of 7:10 what are the measures of those two angles
Answer:
35 degrees and 50 degrees
Step-by-step explanation:
The sum of all the angles in a triangle must be 180 degrees. So 180 - 95 = 85 leftover for the other two angles. Since we have a ratio of 7:10, we can add that up to get 17 total pieces of that 85-degree angle. 85 / 17 = 5, so each piece is 5 degrees. Therefore, the other two angles are 7*5 = 35 degrees and 10*5 = 50 degrees.

Salma and Jared each threw 5 darts at the target shown. Salma scored 19 points by landing 2 darts in A and 3 in B. Jared scored 17 points by landing 1 dart in A and 4 in B. How many points are given for a dart landing in A?
Answer:
5
Step-by-step explanation:
this can be solved using simultaneous equation
2a + 3b = 19 equation 1
1a + 4b = 17 equation 2
Multiply equation 2 by 2
2a + 8b = 34 equation 3
Subtract equation 1 from 3
5b = 15
b = 3
Substitute for b in equation 1
2a + 3(3) = 19
2a = 9 = 19
2a = 10
a = 5
Answer:
Step-by-step explanation:
2a + 3b = 19 equation 1
1a + 4b = 17 equation 2
Multiply equation 2 by 2
2a + 8b = 34 equation 3
Subtract equation 1 from 3
5b = 15
b = 3
Substitute for b in equation 1
2a + 3(3) = 19
2a = 9 = 19
2a = 10
a = 5
