Step-by-step explanation:
multiply by negative three on the first equation then solve
Answer:
(-2, 1)
Step-by-step explanation:
Given:
2x+8y=4...(1)
6x-y=-13...(2)
You would want to have an x or a y value that equals the same in both equations. In this case, we can multiply equation 1 by 3 so that both x's in each equation equal 6x.
(2x+8y=4) x 3...(1)
6x-y=-13...(2)
becomes...
6x+24y=12...(3)
6x-y=-13...(4)
As you can see here, both x's in this equation are equal.
Now we will be combining these equations together. Take the equal x values and make sure they will equal 0. You do that by either subtracting the entire equation or adding it. In this problem, we will be subtracting it because 6x-6x=0
(6x+24y=12) - (6x-y=-13) = 25y =25
Now that we can solve for y separately, 25y=25 y=1
To solve for x, just substitute y into one of the original equations (equations 1 or 2). For this problem, I'll use equation 1.
6x-y=-13
6x-1=-13
6x=-12
x=-2

Without working out the multiplication, which product is larger, why? 3 × 1/5 or 3 × 1/10
Answers
Answer:
The product that will be larger is 3x1/5
Step-by-step explanation:
So in order to know this we have to look at the fractions. We already know that 1/5 is larger than 1/10. To double check our work, we can convert these fractions into percents. 1/5 being 20% and 1/10 being 10%. So now that we have prooved 1/5 is larger, multiplying the larger fraction by three will give us a larger product.

Given kite ABCD with AD=AB, AO=3, and BD=8. Find AD.
This is to find the missing side with Vertex angles of Kite ∠A and ∠C, non-vertex angles are ∠D & ∠B, Main Diagonal bisects ∠A and ∠C and cross diagonal bisects ∠D and ∠B. Please help me find side AD
Answers
Answer:
AD = 5
Step-by-step explanation:
Given:
A kite ABCD with following dimensions:
AD = AB
AO = 3 and
BD = 8
To find:
AD = ?
Solution:
Kindly refer to the attached image for the figure of given dimensions.
In a kite, the following properties hold true:
1. The diagonals of a kite are perpendicular to each other.
2. The longer diagonal(along the vertex angles) bisects the shorter one.
Using above properties:
Looking at the [tex]\triangle AOD:[/tex]
[tex]\angle AOD=90^\circ[/tex]
AO = 3
OD = 4
We know that, Pythagoras theorem hold true in every right angled triangle.
According to Pythagorean theorem:
[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}[/tex]
[tex]AD^{2} = 4^{2} + 3^{2}\\\Rightarrow AD = \bold{5}[/tex]
The value of AD should be 5.
Calculation of the value of AD:Since kite ABCD with AD=AB, AO=3, and BD=8
Here angle AOD = 90 degrees
And, AO = 3 and OD = 4
So, here we use the Pythagorean theorem
[tex]= \sqrt 3^2 + 4^2\\\\= \sqrt{9 + 16} \\\\ = \sqrt{25}[/tex]
= 5
Hence, The value of AD should be 5.

Which equation transforms f(x)=x to a horizontal stretch by a factor of 2, a reflection over the x axis, and a shift down 4?
Answers
Answer:
the one you have selected
Step-by-step explanation:
you already have the correct answer
The expression that represents transformation is [tex]-f(\frac 12x)-4[/tex]
The equation of the function is given as:
[tex]f(x) = x[/tex]
The rule of horizontal stretch by a factor of 2 is represented as:
[tex](x,y) \to (\frac 12x,y)[/tex]
So, we have:
[tex]y = f(\frac 12x)[/tex]
The rule of reflection over the x-axis is represented as:
[tex](x,y) \to (x,-y)[/tex]
So, we have:
[tex]y = -f(\frac 12x)[/tex]
The rule of a vertical shift down by 4 units is:
[tex](x,y) \to (x,y-4)[/tex]
So, we have:
[tex]y = -f(\frac 12x)-4[/tex]
Hence, the expression that represents transformation is [tex]-f(\frac 12x)-4[/tex]

They both say that x must be larger than 3. No bickering here. So yep, they're equivalent.
Inequalities usually have a lot of solutions—in fact, infinitely many. Think about the inequality x > 3. This inequality states that "x must be larger than 3." Any number bigger than 3 is a solution to this inequality. That includes 3.001, 3.0001, 4, 5, 2 million, and every other number bigger than 3. We don't have time at the moment to name them all,
4(g- h) + 10, when g=12, h=7
Answers
Answer:
30
Step-by-step explanation:
When g = 12 and h = 7, the value of the expression is 30.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
The given expression is 4(g - h) + 10.
Substitute the values of g and h as g = 12 and h =7, we get,
4(g - h) + 10 = 4(12 - 7) + 10
= (4 × 5) + 10
= 20 + 10
= 30
Hence the value of the expression is 30.
