Solve Each system using elimination
Answer:
No solution
Step-by-step explanation:
The given system of equations are ,
3x - y = -1 y = 3x - 5 = y-3x = -5Adding both equations ,
=> 3x - y + y -3 x = -1-5
=> 0 = -6
Since we arrived at a contradiction the given pair of equations have No solution .
EQ: How do you use elimination to solve a system of
equations?
Answer:
Step-by-step explanation:
when you use elimination you want to set two of the terms, in the different equations, equal to each other and then subtract the entire equation from the other, so that the two terms cancel out. Then you have an equation with one less variable in it. :)
Which one? Please be honest.
Answer:
x = 24, y = 19
Step-by-step explanation:
Form the question,
Note: opposite side of a parallelogram are equal.
From the diagram,
2x-8 = x+16
Solve for x.
Collect like terms
2x-x = 16+8
x = 24.
Also,
2y = y+19
Solve for y
Collect like terms
2y-y = 19
y = 19.
Hence, x = 24, y = 19.
The first option is correct
Triangle DEF is similar to triangle D'E'F'.Triangle D E F is rotated about point F and is shrunk to form triangle D prime E prime F prime. Which similarity transformation could map △DEF to △D'E'F'? dilation and reflection dilation and translation rotation and dilation rotation and reflection
Answer:
The answer is "Rotation and dilation".
Step-by-step explanation:
The rotation is a spatial movement, which maintains at least one stage. The dilation of a transition affects a figure's dimensions. The center, as well as a scale factor k, are required Which meaning k determines if the expansion is an expansion or a decrease, therefore the above choice is correct because it just rotated and dilated from its original form.

5. find M<C congruent triangles
Answer:
x = 18 / M<C = 114
Step-by-step explanation:
9x - 24 = (2x - 12) + (4x + 42)
9x - 24 = 6x + 30
+24 +24
9x = 6x + 54
-6x -6x
3x = 54
/3 /3
x = 18
C = (4x + 42) = 4(18) + 42 = 72 + 42 = 114
Instant Meals sent out free samples to introduce its new product, Sesame soup. Each sample weighs 69 g. The post office charges thirty-six cents for every 23 g of weight. How much would Instant Meals spend on postage to mail out one hundred eighty-eight samples?
Answer:
$203.04
Step-by-step explanation:
The computation is shown below:
23 ounces to be $0.36
And,
69 ounces be x
So here x
= (69 ounces × $0.36) ÷ 23 ounces
= $1.08
Since there is 188 samples, so the total value is
= $1.08 × 188
= $203.04

Which function describes the arithmetic sequence shown?
7,9, 11, 13, 15, 17,
A)
f(x) = 2x - 5
B)
f(x) = 5x - 2
C)
f(x) = 2x + 5
D)
f(x) = 5x + 2
Answer:
f(x) = 2x+5
Step-by-step explanation:
Given the arithmetic sequence shown
7,9, 11, 13, 15, 17,
THe nth term of the sequence is expressed as;
Tn = a + (n-1)d
a is the first term = 7
d is the common difference = 9-7 = 11-9 = 2
Substitute
Tn = 7 + (n -1)*2
Tn = 7 + 2n - 2
Tn = 2n + 5
Hence the required function is f(x) = 2x+5

Select all the chord(s) in circle G.
DF, EB and FA are the chords in circle G.
What are the properties of the circle?Circles have the following characteristics:
All points in a plane equally spaced from a fixed end known as the centre make up the circle, a closed curve.The radius of the circle is the distance measured from any point in the process to its centre. A circle's radii are all the same size.A section of a straight line connecting two locations on a circle's surface and passing through its centre is said to be the circle's diameter. The radius is twice as long as the diameter.A straight line segment that joins two points on a circle is known as a chord. How to spot a chord is as follows:
On the circle, look for two spots that are not obliquely opposite one another.From these two places, a straight line should be drawn. This line forms one of the circle's chords.Any line segment that crosses the circle at two different locations is also known as a chord.The diameter of a circle is a unique kind of chord that splits the circle in half evenly in the centre.Thus, from the above properties the chord of the given circle G will be DF, EB and FA.

What is the operation in the equation 4a = 24?
Answer: a=6
Step-by-step explanation: Divide each term by 4 and simplify
Answer:
a=6
Step-by-step explanation:
4*a-(24)=0
4a - 24 = 4 • (a - 6)
4 = 0
This equation has no solution.
A a non-zero constant never equals zero.
So a=6

1. Subtract 5 from both sides of the equation.
6 + 5 = 3 + 1 4 6 + 5 − 5 = 3 + 1 4 − 5
2. Simplify
Subtract the numbers 6 = 3 + 9
3. Subtract 3x from both sides of the equation.
6 = 3 + 9 6 − 3 = 3 + 9 − 3

What value of x makes the equation, -3 + 4x + 3(4x + 8)=4(7x + 3)-3 true?
Answer:
x = 1
Step-by-step explanation:
-3 + 4x + 3(4x + 8) = 4(7x + 3) - 3
first, solve the brackets by using the distributive property of multiplication:
3(4x + 8) = 12x + 24
4(7x + 3) = 28x + 12
rewrite equation:
-3 + 4x + 12x + 24 = 28x + 12 - 3
combine like terms:
16x + 21 = 28x + 9
subytact 21 on both sides:
16x + 21 - 21 = 28x + 9 - 21
16x = 28x - 12
subtract 28x on both sides:
16x - 28x = 28x - 28x - 12
-12x = -12
divide both sides by 12
[tex]\frac{-12x}{12} = \frac{12}{12}[/tex]
x = 1
to check, substitute 1 for x:
-3 + 4(1) + 3(4(1) + 8) = 4(7(1) + 3) - 3
-3 + 4 + 12 + 24 = 28 + 12 - 3
37 = 37

The curved surface area of a cylinder of height 28cm is 352sq.cm. Find the diameter of the base of the cylinder
Answer:
d = 4cm
Step-by-step explanation:
curved surface area (CSA) of cylinder = [tex]2\pi rh[/tex]
h = 28cm and CSA = 352[tex]cm^{2}[/tex]
[tex]2\pi rh[/tex] = 352
2 * [tex]\frac{22}{7}[/tex] * r * 28 = 352
[tex]r = \frac{352*7}{2*22*28}[/tex]
after calculating, you will get r = 2cm
so diameter = 4cm
