e first equation into the second equation y=5x+12 3y+4x=150
Step-by-step explanation:
y=5x+12 ....... eqn 1
3y+4X=150.....eqn 2
sub eqn 1 into 2
3(5x+12) + 4X = 150
15X+36 +4X=150
19X = 150-36
19X= 114
X= 6
In triangle PQR, the length of PQ is 5 inches and the length of PR is 9 inches. Give all the possible whole-number lengths of side QR.
Answer:
[tex]4<QR<14[/tex]
5, 6, 7, 8, 9, 10, 11, 12, and 13.
Step-by-step explanation:
We can use the triangle inequality. By the triangle inequality, the sum of any two sides of a triangle must be greater than the remaining side.
In other words, the sum of the two shorter sides must be greater than the longest side.
We know that PQ is 5 and PR is 9.
For the first case, let's say that neither PQ nor PR is the longest side. Instead, QR is the longest side. Then their sum must be greater than QR. Thus:
[tex]5+9>QR\Rightarrow QR<14[/tex]
However, for the second case, let's say that QR is not the longest side. In this case, PR will be the longest side. Therefore, QR plus PQ must be greater than PR:
[tex]QR+5>9\Rightarrow QR>4[/tex]
Thus, we have a compound inequality:
[tex]4<QR<14[/tex]
Therefore, the possible whole-number lengths of QR are:
5, 6, 7, 8, 9, 10, 11, 12, and 13.

Answer:
b = 12.6
Step-by-step explanation:
a*2 + b*2 = c*2
6*2 + b*2 = 14*2
36 + b*2 = 196
Subtract 36 from both sides
36 + b*2 = 196
-36 -36
b*2 = 160
Find the square root of both
b = 12.64911064 or 12.6
Abriana claims that the solution to the system of linear equations y = 2x – 1 and –12x + 3y = 9 is (–2, –5). Select all methods that could be used to prove Paige's claim.
Answer:
Substitution method can be used
Step-by-step explanation:
Given the system of equations
y = 2x-1 ....1
-12x + 3y = 9 ....2
The best method to use id the substitution method
Substitute equation 1 into 2;
From 2;
-12x + 3y = 9
-4x + y = 3
-4x + 2x-1 = 3
-2x -1 = 3
-2x = 3+1
-2X = 4
x = -4/2
x = -2
Substitute x = -2 into 1
y = 2x - 1
y = 2(-2)-1
y = -4-1
y = -5
Hence the solution to the system of equation is (-2, -5)

Rotate the following point (- 5, 7) with a 90 degree CCW rotation
Given:
The point is (-5,7).
To find:
The image of the given point after 90 degrees counter clockwise rotation.
Solution:
If a point rotated 90 degrees counter clockwise, then
[tex](x,y)\to (-y,x)[/tex]
Let the given point is P(-5,7). Using the above rule, we get
[tex]P(-5,7)\to P'(-7,-5)[/tex]
Therefore, the image of the given point after 90 degrees counter clockwise rotation is (-7,-5).

Answer:
x < 7
Step-by-step explanation:
-8x + 40 > -16
-8x > -16 - 40
x < -56/-8
x < 7
(when changing sides of neg. multipliers, you need to change the sign side, dont fall for that common mistake)
Answer:
x < 7
Step-by-step explanation:
-8x + 40 > -16 (subtract 40 on both sides)
-8x > -56 (divide by -8) - be careful and don't forget to flip the sign when dividing by a negative number
x < 7 (final answer)
An angle measures 134.6° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
angle y = 22.7 degrees
angle x = 157.3 degrees
Step-by-step explanation:
Angle x + angle y = 180 because they are supplementary.
Angle x = angle y + 134.6 degrees
2y + 134.6 = 180
2y = 45.4
y = 22.7 degrees
x = 157.3 degrees

I use the rectangle to make 4 triangles. Each triangle is the same size. What is the area of one of the triangles?
Answer:
Divide the rectangle's area by 4 to get the area of one triangle
Step-by-step explanation:
The area of one triangle is one-quarter area of the rectangle.
We need to find the area of the triangle.
How to find the area of the triangle?Since we have a rectangle, and there are 4 triangles in the rectangle. Also, each triangle is the same size.
Let
A = area of reactangle and A' = area of one triangle.So, area of rectangle, A = area of 4 triangles
= 4 × area of one triangle, A'
= 4A'
A = 4A'
Making A' subject of the formula, we have
A' = A/4
So, the area of one triangle is one-quarter area of the rectangle.

What is the sum of 8 5/6+ 5 11/24?
Enter your answer in the box as a mixed number in simplest form.
Answer:
14 7/24
Step-by-step explanation:
There are two different denominators here: 6 and 24. The LCD is 24, and so 8 5/6 becomes 8 20/24.
Then the SUM of the two given mixed numbers is:
8 20/24 + 5 11/24 = 13 31/24, or, when properly reduced, 14 7/24

Answer:
A. 33.3%
Step-by-step explanation:
On a dice, we have the numbers 1, 2, 3, 4, 5, and 6. The question is asking for the probability of anything greater than 4. This means we're trying to find the probability of rolling a 5 or a 6 since those are the only numbers greater than 4 on a dice. We can write this as a fraction.
There are six numbers total, so that will be the bottom of our fraction. We have two numbers that are greater than 4. This means we will write our fraction like so:
[tex]\frac{2}{6}[/tex]
Next, we can simplify the fraction by 2, leaving us with 1 over 3, like this:
[tex]\frac{2}{6} = \frac{1}{3}[/tex]
Finally, just divide the 1 by 3 to get 0.333, or 33.3% when you move the decimal two places to the right. Hope this helps!
