Answer:
8
Step-by-step explanation:
whatever was done to y needs to be done to x.
in this case (y) was 2x so you need to 2x (x) making 4 into 8
What property was used in step 1 to arrive at step 2?
Step 1: 5 (x minus 7) = 55. Step 2: 5 x minus 35 = 55. Step 3: 5 x = 90. Step 4: x = 18.
Answer:
Distributive Property
Step-by-step explanation:
5(x - 7) = 55 ⇒ 5x - 35 = 55
The 5 was distributed in 5(x-7) to get 5x - 35.

Answer:
1. -1/2
2. Graph attached below:
Step-by-step explanation:
1) To find to slope of the line with two points would be the following equation:
[tex]y_{2} - y_{1} / x_{2} - x_{1}[/tex]
So let’s assume our variables and subsitute them to see that the Carma’s Working out is an error.
Form: [tex](x_{2}, y_{2}), (x_{1}, y_{1})[/tex]
[tex]y_{2} = 3[/tex]
[tex]y_{1} = 1[/tex]
[tex]x_{2} = 7[/tex]
[tex]x_{1} = 11[/tex]
[tex]3 - 1 / 7 - 11 = -1/2[/tex]
1. Error one: The point values of the slope aren‘t correctly labeled and are not the same form as in the formula.
2. Error two: The slope output is not correct, it is 2 but the slope is -1/2.
Now let’s get on the graph of Carma’s workout, I can spot that the point (-4, 5) is not plotted correctly. Instead it is plotted (4, -5). To understand clearly I will label these points on a graph, image attached below:
3. Error three: The point (-4, 5) is not plotted correctly, x should be negative and y should be positive.
4. Error four: The slope is not correct, instead the slope of the graph is negative but we need a positive slope.
Now it is time to fix Carma’s mistakes:
1) Slope: -1/2
2) Graph attached below
A supervisor finds the mean number of miles that the employees in a department live from work. He finds x Overbar = 29 and s = 3. 6. Which mileage is within a z-score of 1. 5? 21 miles 24 miles 36 miles 41 miles.
The correct option is (B).24 miles.
Z-score is basically another term for the specific number of standard deviations. I suppose we can assume normality here, even though it isn't given, so I'd make a rough sketch.
Otherwise, just use the basic formula:
[tex]z_{score} =\dfrac{x-\mu}{\sigma}[/tex]
Given that,
[tex]\bar{x}=29[/tex] (statistic for a mean) and [tex]s=3.6[/tex] (statistic for a standard deviation).
Since z-score must be Less than 1.5, So
[tex]1.5> \dfrac{x-29}{3.6}\\[/tex]
[tex]1.5 \times3.6 > x-29\\5.4+29> x\\34.4> x[/tex]
I just used normal cdf and got [tex]23.6<x<34.4[/tex].
Hence the correct option is (B).24 miles.

Step-by-step explanation:
( 2 , 1 )

What is the least angle measure by which this figure can be
rotated so that it maps onto itself?
O 45°
O 90 °
O 180°
O 360°
Answer:
Step-by-step explanation:
360° degrees
The least angle measure by which this figure can be rotated so that it maps onto itself is 360 degrees option (D) 360° is correct.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
It is given that:
The two-dimensional figure is shown in the picture.
As we know from the definition of the geometric transformation; the change in coordinates and the shape of the geometrical body and geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
The least angle measure by which this figure can be rotated so that it maps onto itself is 360 degrees
Because the rotation of 45, 90, and 180 degrees cannot map the figure onto itself.
Thus, the least angle measure by which this figure can be rotated so that it maps onto itself is 360 degrees option (D) 360° is correct.

Answer:
x = 2 and x + y = -3
Step-by-step explanation:
With the xy example filled, I could work out that x was 2 by realising that if y was -5, then to get to -10 it'd have to be multiplied by two, and I just added -5 and 2 after working out x for the bottom grid.
Hope this helps and you have a good day!
Left box is two (2) and the bottom box is negative three (-3)...
...You are given y, which is -5. We need to figure out x to fill the other 3
boxes or diamonds. xy is another way of saying x * y, so we know that
x * -5 = -10. We can use division to solve this. -10 / -5 = x, or 2. Now we can
fill in the top and left diamond. All that's left is to add x and y, or 2 and -5
together.
2 + -5 = -3
Top diamond : -10
Left diamond : 2
Bottom diamond : -3
Right diamond : -5
Hopefully this helps.

Answer:

Step-by-step explanation:
So she went there 4 times. Each time, she pays for the salad itself (we don't know how much) and she also leaves a 1,50 dollar tip. All together, she paid 54 dollars.
-> TIPS: 4x 1,50= 6 (dollars)
-> SALADS: 54 (total amount she paid) - 6 (tips) = 48 (all the 4 salads she bourght)
-> 1 SALAD: 48/4=12
-----------linear equation:-------------
54 = 4 x 1,5 + 4 x c
54 = 6 + 4c
48 = 4c
12 = c

Get the slope by using derivative:
dy/dx= 1/2
dy/dx= slope of the normal line
Since we are looking for slope of the tangent line:
Use Mn=-1/Mt
The slope of the tangent line is -2
Using point slope form:
(y-y1)=m(x-x1) ; where x1=7, y1=10, and m=-2
y-10=-2(x-7)
y-10=-2x+14

Answer:
it's AAS is my opinion
Step-by-step explanation:
Answer:
AAS
Step-by-step explanation:
we can eliminate two of the answer choices from the start. AA and SSA do not prove triangle congruence. we are then left with SAS and AAS. we can see that there is one pair of sides and one pair of angles marked congruent on the triangles. the triangles are formed by intersecting lines which form vertical angles. according to the vertical angles theorem, those two angles will be congruent. therefore, these triangles are proven congruent by AAS. hope this helps!

Since the line is parallel, it has the same slope -- 3
y = 3x + b, sub point (1, 9)

9 = 3 + b
b = 9 - 3
b = 6

Find the surface area of the cuboid.
Answer:
62 cm²
Step-by-step explanation:
The surface area (SA) is the sum of the areas of the 6 faces.
The opposite faces are congruent, then
SA = area of front/ back + area of top/ bottom + area of 2 sides
= 2(5 × 3) + 2(5 × 2) + 2(3 × 2)
= 2(15) + 2(10) + 2(6)
= 30 + 20 + 12
= 62 cm²
