The pair of figures is similar. Find x. Round to the nearest tenth if necessary.
A. 34 cm
B. 9.8 cm
C. 21.9 cm
D. 29.6 cm
Answers
Answer:
Choice B
Step-by-step explanation:
When two shapes are similar their sides are always going to be proportional. So here we will set up a proportion to solve this.
[tex]\frac{23}{40}=\frac{x}{17}[/tex]
Now we cross multiply
[tex]391=40x[/tex]
After we got an equation we solve it
[tex]x=9.775[/tex]
Since we got a decimal we will have to round it to the place they instruct for us, on this one it is 9.8 cm so it is choice b.
The required value of x is 9.8 cm. For the two similar triangles.
Two similar triangles are given. value of x to be determined.
Similar triangles are those triangles that have similar properties,i.e. angles and proportionality of sides.
Here, if triangles are similar then their ratio of sides is also equal.
x/23=17/40
x = 0.425*23
x = 0.425 * 23
x = 9.8 cm
Thus, The required value of x is 9.8 cm. For the two similar triangles.

Answers
Answer:
for a vertical line the value of x, in this case 9, will never change. this will be true for any value of y. therefore the equction for vertical line line passing through this point is; x=9 likewise, for a horizontal line the value of y, in this case -4 will never change. this will be true for any value of x. therefore the equation for a horizontal line passing through this points is; y=-4

What is the value of x in the solution to the this system of equations:
y=-1/2x + 2
y - 2x = -3
Answers
Answer:
x=2 and y=1
Step-by-step explanation:
hope this helps!
Answer:
x = 2
Step-by-step explanation:
For system of equations, you need to equal them to each other. First, you need to isolate y on one side of the equation in [tex]y - 2x = -3[/tex]
[tex]y = -3 + 2x[/tex]
Now, equal the equations to each other:
[tex]-\frac{1}{2}x + 2 = -3 + 2x[/tex]
Add [tex]\frac{1}{2} x[/tex] to both sides of the equation:
[tex]2 = -3 + (2x + \frac{1}{2}x) = -3 + (\frac{4}{2}x + \frac{1}{2}x) = -3 + \frac{5}{2} x[/tex]
Subtract add 3 to both sides of the equation:
[tex]5 = \frac{5}{2}x[/tex]
Divide [tex]\frac{5}{2}[/tex] on both sides of the equation. Remember: when you divide a fraction, you multiply by the reciprocal. See below:
[tex]\frac{2}{5} * 5 = x[/tex]
[tex]\frac{10}{5} = x[/tex]
[tex]x = 2[/tex]
Check your work:
[tex]-\frac{1}{2}(2) + 2 = -3 + 2(2)[/tex]

The first company charges $40 per backpack and a $10 shipping fee for the order and the second company charges $38 per backpack and $16 shipping fee. How many backpacks would a customer need to order from either company so that the cost of the order was the same from both companies
Answers
Answer: 3
Step-by-step explanation:
Multiply $40 by 3 then add 10 to get 130.
Multiply $38 by 3 then add 16 to get 130.
The number of backpacks a customer would need to order from either company so that the cost of the order was the same for both companies is 3 backpacks.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
First company:
Charges per backpack = $40
Shipping fee = $10
We can write an equation for the cost of x backpacks of the first company:
10 + 40x _____(1)
Second company:
Charges per backpack = $38
Shipping fee = $16
We can write an equation for the cost of x backpacks for the second company:
16 + 38x ______(2)
The number of backpacks a customer would need to order from either company so that the cost of the order was the same for both companies:
From (1) and (2) we get,
10 + 40x = 16 + 38x
Subtract 10 on both sides
10 + 40x - 10 = 16 + 38x - 10
40x = 6 + 38x
Subtract 38x on both sides.
40x - 38x = 6
2x = 6
Divide 2 on both sides.
x = 3
Thus,
The number of backpacks a customer would need to order from either company so that the cost of the order was the same for both companies is 3 backpacks.

A line passes to the point (4,6) and has a slope of -3/4. Which is the equation of the line
Answers
Answer:
Step-by-step explanation:
use point-slope formula [ y- y1 = m(x - x1) ] with the point you are given as point 1 (x1,y1) = (4,-6) and the slope m that you are also given m = -3/4
y-y1 = m(x -x1)
y-(-6) = -3/4(x -4)
y + 6 = -3/4(x-4)
you can work this toward the slope-intercept formula of y = mx +b by doing the following
y + 6 = -3/4x +3 (distribute the -3/4)
y = -3/4x + 3 -6 ( move the 6 to the other side )
y = -3/4x - 3

Answer:
the value of the given equation is 8
Step-by-step explanation:
The computation is shown below
Given that
13 - 0.75w + 8x
here w = 12
x = 1 ÷ 2
Now put these values to the above equation
= 13 - 0.75 × (12) + 8 × (1 ÷ 2)
= 8
