Answer:

  (x, y) = (3, 7)

Step-by-step explanation:

If you divide the second equation by 2, it becomes ...

 -x +2y = 11

Adding this to the first equation gives you the value of y:

  (x -y) +(-x +2y) = (-4) +(11)

  y = 7 . . . . . . . . simplify

The first equation can be rearranged to give an expression for x:

  x = y -4

  x = 7 -4 = 3

Then the solution is seen to be (x, y) = (3, 7).

Step-by-step explanation:

It's asking what best represents -188, so in the problem it has to be negative (have keywords like decreasing, debt, minus, etc) which leaves answers A and D, D. has a decreasing of inches (4), however the hours aren't decreasing so the answer is A

Answer:

Step-by-step explanation:

x+y=14

y=14-x

2x+3y=32, using y=14-x we have

2x+3(14-x)=32

2x+42-3x=32

-x+42=32

-x=-10

x=10, and since y=14-x

y=14-10=4

So Amelia made 10 two-pointers and 4 three-pointers.

Answer:

My family is traveling faster, since it is traveling at the rate of 950 miles per day, while the other family travels at 900 miles per day.

Step-by-step explanation:

Since I am taking a trip at the same time as another family, and my family traveled 1,900 miles in 2 days, while their family traveled 2,700 miles in 3 days, to determine who is traveling faster the following calculation must be performed:

1,900 / 2 = 950

2,700 / 3 = 900

Thus, my family is traveling faster, since it is traveling at the rate of 950 miles per day, while the other family travels at 900 miles per day.

The value of f(10)+10 for the given function is 32.

The given functions are  f(x) = 3x-8 and g(x) = -x²+ 4x-11.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

1) Put x=10 in the function f(x) = 3x-8, we get

f(10)=3(10)-8

= 22

So, f(10)+10

= 22+10=32

2) Put x=-9 in the function g(x) = -x²+ 4x-11, we get

g(-9)=-(-9)²+4(-9)-11

= -81-36-11

= -128

So, g(-9)+7

= -128+7

= -121

3) Put x=4 in the function g(x) = -x²+ 4x-11, we get

g(4) = -(4)²+4(4)-11

=-16+16-11

=-11

Now, -2xg(4) =-2x(-11)

=22x

4) Put x=-4 in the function f(x) = 3x-8, we get

(-4)=3(-4)-8

= -20

Put x=7 in the function g(x) = -x²+ 4x-11, we get

g(7)=-(7)²+4(7)-11

= -49+28-11

= -32

5. Given f(x)= 9 –2x, if f(x)= 19

Now, 9-2x=19

⇒ -2x=10

⇒ x=-5

Therefore, the value of f(10)+10 for the given function is 32.

Step-by-step explanation:

6 feet =12

6 feet = 6x2

11 feet shadow 11/2

answer=5.5

The height of the diane when the height of euardo and diane cast should be given so it should be 5.5.

Since

HEIGHT Eduardo is 6 feet tall and casts a 12-foot shadow. At the same time, Diane casts an 11-foot shadow.

So,

6 feet tall = 12

Now for 11 foot it should be half like 5.5

Hence, The height of the diane when the height of euardo and diane cast should be given so it should be 5.5.

Angle x has a size of 69.

What exactly is a phrase?

One or more terms in an equation can be added, subtracted, multiplied, or divided.

When we simplify an expression, we always merge similar terms in the expression.

If an expression has two sides, we also preserve all similar terms on one side of the expression.

Example:

An expression is 1 + 3x + 4y = 7.

3 + 4 is a formula.

A formula is 2 x 4 + 6 x 7 - 9.

There is an expression: 33 + 77 - 88.

We can determine the angle in a circle given two angles of 168 degrees and 123 degrees.

168°+123°+x°=360°

291°+x°=360°

291°-x°=360 °

x=69°

The correct step to translate f(x) = 3ˣ to g(x) = 3ˣ⁺¹ + 4 is:

Shift f(x) = 3ˣ one unit to the right and four units up. So option C is correct

Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).

This means that for every x value,

we add 4 to the y-value and move the y-value one unit to the right.

To see this graphically, imagine a graph of the equation f(x) = 3x.

This graph will be a line that passes through the origin (0,0) and has a slope of 3.

If we shift this line one unit to the right, then the x-intercept (the point where the line crosses the x-axis) will change from (0,0) to (1,0).

If we also add 4 to the y-value of every point on this line,

then the y-intercept (the point where the line crosses the y-axis) will change from (0,0) to (0,4).

The resulting graph will be the graph of the equation g(x) = 3ˣ⁺¹ + 4.

Answer:

x+y=4

Step-by-step explanation:

No solution means that the lines will never intersect. We know that the slope of line A is -1, and it's y intercept is 2. If you look at the last option for the answer choices, it's slope is also -1, but it's y intercept is at 4. These lines have the same slope, also known as parallel, so they will never intersect, thus giving no solution
