10:20 and 7:14. They all are 1/2 and the ratio 1:2 equals one half

Answer:b

Step-by-step explanation:

Answer:

y= 3/2x + 1

Step-by-step explanation:

slope intercept form is y=mx+b. the m is the slope and the b is the y intercept. the y intercept is 1, where it crosses the y axis. the slope is 3/2 because from the y intercept which is 1, you go up 3 and over 2 right.

Answer:

x=-2, y=3

Step-by-step explanation:

substitute 11 + 4x into the second equation for y

3x + 2(11+4x) =0

3x +22+8x=0

11x=-22

To solve for y: y=11+4(-2)

Answer: He bought 7 nachos.

Step-by-step explanation:

Let x= Number of cokes

y = Number of nachos

As per given , we have

x+y=12     (i)

2.50x+3.50y=37    (ii)

Multiply 2.5 on both sides of (i), we get

2.5x+2.5y= 30      (iii)

Subtract (iii) from (ii), we get

y=7      (iv)

Put value of y from (iv) in (i), we get

x+7=12

⇒ x= 12-7

⇒ x=5

Hence, he bought 5 cokes and 7 nachos.

Answer:

liner Y=9(2x)  Y=5x-3

Step-by-step explanation:

The equations which are linear are

a) y = 9( 2x )

b) y = ( 5x + 3 )2

d) y = 5x - 3

The equations which are non linear are

c) y = 8x²

e) y = 3x² + 2x - 1

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

a)

Let the equation be y = 9( 2x )

Now , on simplifying the equation , we get

y = 18x

Now , this is a linear equation in 2 variables of the from y = mx + c

So , the equation is linear

b)

Let the equation be y = ( 5x + 3 )2

Now , on simplifying the equation , we get

y = 10x + 6

Now , this is a linear equation in 2 variables of the from y = mx + c

So , the equation is linear

c)

Let the equation be y = 8x²

Now , on simplifying the equation , we get

y = 8x²

This is a quadratic equation , and is not linear

So , the equation is non linear

d)

Let the equation be y = 5x - 3

Now , on simplifying the equation , we get

y = 5x - 3

Now , this is a linear equation in 2 variables of the from y = mx + c

So , the equation is linear

e)

Let the equation be y = 3x² + 2x - 1

Now , on simplifying the equation , we get

y = 3x² + 2x - 1

This is a quadratic equation , and is not linear

So , the equation is non linear

Hence ,

The equations which are linear are y = 9( 2x ) , y = ( 5x + 3 )2 and y = 5x - 3

The equations which are non linear are y = 8x² and y = 3x² + 2x - 1

The expressions that are equivalent to [tex]3\frac{1}{4} -(-\frac{5}{8} )[/tex] are

[tex]3\frac{1}{4} +(\frac{5}{8} ) \\\\3\frac{1}{4} +(+\frac{5}{8} )[/tex]

for understanding check the calcualtions here

an expression is the combination of numbers and operators like +, - * or /

If we have any equal sign then it is an equation .

Given expression is :

[tex]3\frac{1}{4} -(-\frac{5}{8} )[/tex]

to find out equivalent expression  we  remove the parentheisis  by multiplying negative inside the parenthesis

Negative  times negative becomes positive

first fraction is positive . So it remains the same

Multiply negative inside the parenthesis . Negative times negative is positive

so, the equivalent expressions are

[tex]3\frac{1}{4} +(\frac{5}{8} ) \\\\3\frac{1}{4} +(+\frac{5}{8} )[/tex]

Answer: [tex]-2 \leq x \leq 9[/tex]

Step-by-step explanation:

The domain is the set of x-values for which the relation is defined.

The domain of the graph will be -2 ≤ x ≤ 9 which is shown in the given figure.

The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.

The domain of a graph is the set of all possible input values (also called the independent variable) that can be plotted on the graph. In other words, it is the range of values that the horizontal axis (also called the x-axis) of the graph covers.

To determine the domain of a given graph, you will need to look at the labels and scale of the x-axis.

The domain of a graph is the set of all possible input values in intervals as -2 ≤ x ≤ 9 that can be plotted on the graph.

Thus, the domain of the graph will be  -2 ≤ x ≤ 9, as indicated in the illustration.
