Solve the following system of equations. Express your answer as an ordered pair in the format (a,b), with no spaces between the numbers or symbols.

2x+5y=16
-5x-2y=2

y = 4(2) + 2

= 8 + 2 = 10

Answer : y = 10

Answer:

10

Step-by-step explanation:

Given

y = 4x + 2 ← substitute x = 2 into the equation

y = 4(2) + 2 = 8 + 2 = 10

Answer:

Step-by-step explanation:

The easiest way to do this is to use the distributive property.

Put the brackets around the terms on the right.

b = (f^2 * A +  2HA)

A is a common factor on the right.

b = A * (f^2 + 2H)

Now divide by f^2 + 2H

b/(f^2 + 2H) = A

You subtract 3 from the x coordinate. The y coordinate stays the same.

The rule is [tex](x,y) \to (x-3, y)[/tex]

Answer: (y - 7) = M*(x - 4)

Step-by-step explanation:

Point-slope form is written as:

y - y1 = M*(x - x1)

where M is the slope, and the point is (x1, y1)

In this case we only know the point, so we can write this as:

(y - 7) = M*(x - 4)

Where the value of the slope is not known, then we have infinite possible lines defined in that equation

Answer:

correct choice is option 3 - figure C.

Step-by-step explanation:

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. This gives you such reflection rule:

From the diagram:

L(3,1), M(4,3), N(5,3) and P(4,1).

Using the reflection rule, you can find coordinates of image points:

L'(1,3), M'(3,4), N'(3,5) and P'(1,4).

As you can see, these are coordinates of vertices of the figure C.

Answer:

The line of best fit for your specific question is a linear equation.

Step-by-step explanation:

A linear equation has a constant rate of growth/decline and the growth/decline rate will never change in an linear equation.

If you draw a line that approximately splits between all the data plots, you will notice the line you drew is very close to the data points.

If the data plots was a quadratic, it would be very hard to draw a line of best fit.

Linear equations can easily be identified in a graph because it is a straight line.

Perhaps insert this equation into your graphing calculator or other graphing software online (like Desmos): y = 3x+2

A quadratic equation can also easily be identified in a graph because, in most cases, it looks like a U.

Take these examples: y = [tex]3x^2+5x+2[/tex] or y=[tex]-2x^2+10x+30[/tex]

Answer:

0

Step-by-step explanation:

just put b

The slope of a line parallel to the line y = -1/5, will be equal to the slope of this line. So, the slope m = 0.

The equation of a line is the representation of a line on a coordinate plane (x-y plane), which shows the relation between x and y, for every point on the particular line.

The standard form of a line is ax + by = c, where x and y are variables and a, b, and c are constants.

The slope-intercept form of a line is y = mx + b, where x and y are variables, m is the slope of the line, and b is the y-intercept of the line.

If the slope of two parallel lines is m1 and m2, then m1 = m2.

We are asked to find the slope of a line that is parallel to the line y = -1/5.

Writing this equation in the slope-intercept form: y = 0(x) + (-1/5)

Comparing the given equation to the slope-intercept form of a straight line, y = mx + b, we get slope of this line m = 0.

We are asked to find the slope of a line parallel to the line y = -1/5. Since the lines are parallel, the slopes of both lines are equal.

∴ The slope of the line parallel to y = -1/5 is 0.

[tex]\huge\boxed{\text{1.}}[/tex]

She did the ratio of GIRLS to BOYS, while the question asked for the ratio of BOYS to GIRLS. Therefore she swapped her proportion and data can get mixed up when you swap them. It's always important to keep the proportion in the same way that it was asked.

[tex]\huge\boxed{2.}[/tex]

[tex]\text{15 to 13}[/tex]

[tex]\text{15:13}[/tex]

[tex]\frac{15}{13}[/tex]

Step-by-step explanation:

We have 13 girls and 15 boys in the class. Therefore we can represent this as [tex]\frac{g}{b} = \frac{13}{15}[/tex], where g is the number of girls and b is the number of boys. Now let's look at what the question is asking.

"She wrote the ratio of boys to girls in 3 ways."

Note: boys to girls. Our original proportion is currently at girls to boys. Therefore these proportions are swapped. We can see that she messed this up.

Therefore, we need to swap the values.

So 13 to 15 becomes 15 to 13

13:15: becomes 15:13

[tex]\frac{13}{15}[/tex] becomes [tex]\frac{15}{13}[/tex].

Answer:

he rode the roller coaster 4 times the bumper cars 3 times and the water slide 4 hoped i helped

Step-by-step explanation:

The question is an illustration of a system of simultaneous equation

He rode the roller coaster 5 times; bumper cars 1 time and water slides 4 times.

Let:

[tex]b \to[/tex] bumper cars

[tex]r \to[/tex] roller coaster

[tex]w \to[/tex] water slides

He rode 10 total rides.

So:

[tex]b + r + w = 10[/tex]

The equation for the times he waited is:

[tex]r + \frac{20}{60}b + \frac{15}{60}w = 6\frac{20}{60}[/tex]

Simplify fraction

[tex]r + \frac b3 + \frac w4 = 6\frac 13[/tex]

The proportion of rides is:

[tex]r =b + w[/tex]

Substitute [tex]r =b + w[/tex] in [tex]b + r + w = 10[/tex] and [tex]r + \frac b3 + \frac w4 = 6\frac 13[/tex]

[tex]b + b + w + w = 10[/tex]

[tex]2b + 2w = 10[/tex]

Divide through by 2

[tex]b + w = 5[/tex]

Similarly

[tex]r + \frac b3 + \frac w4 = 6\frac 13[/tex]

[tex]b + w + \frac b3 + \frac w4 = \frac{19}3[/tex]

Multiply through by 12

[tex]12b + 12w + 4b + 3w = 4 \times 19[/tex]

[tex]16b + 15w = 76[/tex]

Make b the subject in [tex]b + w = 5[/tex]

[tex]b = 5 -w[/tex]

Substitute [tex]b = 5 -w \\[/tex] in [tex]16b + 15w = 76[/tex]

[tex]16(5 -w) + 15w = 76[/tex]

[tex]80 -16w + 15w = 76[/tex]

Collect like terms

[tex]-w = 76 - 80[/tex]

[tex]-w = -4[/tex]

[tex]w = 4[/tex]

Recall that:

[tex]b = 5 -w[/tex]

[tex]b = 5 - 1[/tex]

[tex]b =4[/tex]

Recall that:

[tex]r =b + w[/tex]

[tex]r = 1 + 4[/tex]

[tex]r = 5[/tex]

Hence, he rode the roller coaster 5 times; bumper cars 1 time and water slides 4 times.

Irrational

Step-by-step explanation:

I hope this helps you :)

The number 4.46466 is a rational number.

Rational numbers are numbers that can be written as the ratio of two integers. For example: 1/2, 3/4, are rational numbers

Irrational numbers, any real number that cannot be expressed as the quotient of two integers—that is, p/q, where p and q are both integers. For example, there is no number among integers and fractions that equals Square root of√2.

Now,the given number is 4.46466 .

Here we see that digits after decimal 46466 stops,

hence the given number can be convert into fraction of the form a/b

So,

4.46466 = 446466 /100000

So 4.46466 can be expressed in the form of a/b

Therefore 4.46466 is rational.
