How to simplify -7 + 3 - 20

Answer:

y=4/3x+19/3

Step-by-step explanation:

perpendicular = slope is the negative reciprical.

plug in the point (-4,1) for (x,y)

1(y)=4/3(-4)+b

1=-16/3+b

Answer:

The angle diagonal to angle H = 45

The other two angles equal 135

Step-by-step explanation:

A line equals 180. So 45+135 = 180

I'm sorry that I couldn't list names of the angles. I would need a picture. I hope this made since and could help. God bless!

The measure of angle J is 45 degrees and The measure of angle K is also 45 degree. In a parallelogram, opposite angles are congruent, meaning they have the same measure.

Given that angle H measures 45 degrees, we can use this property to find the measures of angles J and K.

Measure of Angle J:

Since angle J is opposite to angle H in parallelogram HIJK, angle J will also measure 45 degrees. This is because opposite angles in a parallelogram are equal.

Measure of Angle K:

Similarly, angle K is opposite to angle I in parallelogram HIJK. Since the opposite angles are congruent, angle K will also have a measure of 45 degrees.

In summary, the measure of angle J in parallelogram HIJK is 45 degrees, and the measure of angle K is also 45 degrees. This is a property of parallelograms where opposite angles are congruent.

The side ST is 10. If the quadrilateral Q is reflected, and the side is 10, the others should also have 10 as the side for ST.

Answer: 31.6

Step-by-step explanation:

Answer:

270°

Step-by-step explanation:

∠ PQR = 90° ( angle in a semicircle )

PRST is a cyclic quadrilateral

The opposite angles in a cyclic quadrilateral are supplementary, sum to 180°

Then

∠ PRS + ∠ PTS = 180°

∠ PQR + ∠ PRS + ∠ PTS = 90° + 180° = 270°

Step-by-step explanation:

the general slope intercept form is

y = ax + b

a is the slope. it is expressed as ratio of y change / x change when going from one point to another.

b is the y-intercept (the point, where the line crosses the y-axis, meaning the y value when x=0).

we get b by using the point coordinates in the equation and solve for b.

we see costs is on the y axis, and miles is on the x axis.

so what points do we identify on the chart for the green taxi ?

there is right on the y-axis (0, 5). which is already our y-intercept.

and then let's pick e.g. the point where both lines intercept : (3, 8).

for the slope we look at the coordinate changes :

x changes by +3 (from 0 to 3).

y changes by +3 (from 5 to 8).

so, the slope is 3/3 = 1.

and again, the y- intercept is +5.

therefore, the line equation is

y = x + 5

meaning the cost of a fare is the number of miles plus 5.

So, the average rate of change is 0.475.

Step-by-step explanation:

If n = 2, then f(n) = 8.82. If n = 6, then f(n) ≈ 10.72. Now, 10.72 – 8.82/ 6 – 2 = 1.9/ 4 = 0.475.

Parallel lines have the same slope.

So if one line has a slope of 4, then the slope of the line parallel to it has a slope of 4 as well.

Step-by-step explanation:

you don't understand what the multiplication or division with 10 (or a higher power of 10) does ?

or you don't know. what 10² means ?

this means 10 to the power of 2 or 10 squared and is simply 10 multiplied with itself 2 times : 10×10.

and 10×10 is ... 100.

as you can imagine, this is not restricted to the number 2 (and 10). "power of" can be any number and just indicates how often the base number is multiplied with itself.

a surcharge case is "power of 0", which is simply 1.

now that we understand that, let's have a quick look at how the numbers we are dealing with (in daily life as well as in class and in science) are actually built :

when I write e.g the number

1234

then this actually means

4×10⁰ + 3×10¹ + 2×10² + 1×10³

when I multiply this now by e.g. 10 this becomes

4×10⁰×10 + 3×10¹×10 + 2×10²×10 + 1×10³×10 =

4×10¹ + 3×10² + 2×10³ + 1×10⁴

as you can see, the previous "single" position 4 now becomes a 40.

and the result looks in short form :

12340

so, a multiplication by 10 adds a 0 at the low end of the number.

a multiplication by 10² or 100 (= 10×10) adds then 2 0s at the low end. and so forth.

a division by 10 does the opposite and removes a 0 at the low end of the number.

but what if we don't have any 0 at this position of the number ? then we enter the system of the decimal point.

because on the right side of the decimal point we continue to countdown the exponent of 10 below 0.

the first position right of the decimal point stands for 10^‐1, the second position for 10^‐2, and so forth. and that is nothing else than tenths, hundredths, thousandths, ...

so, in short, a multiplication by 10 moves the decimal point one position to the right. and if we run out of written positions, then we can simply assume an infinite sequence of 0s continuing further to the right.

and a division by 10 moves the decimal point one position to the left. and if we run out of written positions, then we can simply assume an infinite sequence of 0s continuing further to the left too that are then showing up on the right side of the decimal point.

now, I think we covered all the basics and we can look at the question here :

10² × 18.72

10² = 100 = 10×10

so, we are multiplying twice by 10 and move the decimal point therefore 2 positions to the right.

the result is then

1872

as a little guide : when it is clear that the number has to get bigger by the operation (like a multiplication by 10 or 100), you need to move the decimal point in the direction that makes the number bigger (which is to the right).

and if the operation is clearly trying to make the number smaller, then you have to move the decimal point in the direction to make the number smaller (to the left).

Step-by-step explanation:

for qs 15-18 since x is 1 or -1 if you sq 1 or -1 you will always get 1

so y is the "a" value in the equation  y=ax²

for qs 19

y=ax²

so if a>1 -- then vertical stretch

when 0<a<1 -- then vertical compressed
