I really need help with these two problems, and yoI help would be much appreciated.

Answer:

y - intercept = 0 [(0,0)]

Step-by-step explanation:

Given the equation y - 2.30 = 1.15(x-2), the y-intercept is when x is 0.

So to find your answer, just substitute in 0 for x, and solve for y:

y - 2.30 = 1.15(x - 2) →

x = 0

y - 2.30 = 1.15(0 - 2) →

y - 2.30 = 1.15(-2)

y - 2.30 = -2.30 →

+2.30 +2.30

y = 0

What is an algebraic expression?

an algebraic expression is an expression built up from integer constants, variables, and algebraic operations.

Example of an algebraic expression

3x² − 2xy + c is an algebraic expression. Since taking the square root is the same as raising the power, is also an algebraic expression

seven divided by twice a number 7 ÷ 2n or

three times a number decreased by 11 3n - 11

Answer:

Step-by-step explanation:

The equation y = -3x + 5 represents a linear function. The -3 represents the slope of the line. This means that the slope is -3 . The 5 in the equation represents the y-intercept of the line. This is where the graph crosses the y-axis.

Compare the original equation with the standard form to get all the values.

[tex]y=-3x+5\\y=mx+c[/tex]

If we compare m= -3 and c=+5 where m is the slope/gradient and c is the y-intercept.

The equation y = -3x + 5 represents a Linear function. The -3 represents the slope of the line. This means that the slope is -3. The 5 in the equation represents the y-intercept of the line. This is where the graph crosses the y axis.

Therefore,

Compare the original equation with the standard form to get all the values.

y = -3x + 5

y = mx +c

If we compare m = -3 and c = 5 where m is the slope/gradient and c is the y-intercept.

Answer:

Step-by-step explanation:

Given the expression [tex](4z^8)^{-3}[/tex], to evaluate this, we will use one of the law of indices as shown;

[tex](a^m)^n = a^{mn}[/tex]

[tex]4^{-3} * z^{8*-3}[/tex]

[tex]= \frac{1}{4^3} * z^{-24}\\ \\= \frac{1}{64} * \frac{1}{z^{24}}\\ \\= \frac{1}{64z^{24}}[/tex]

Mario's error was that she did not raise the value of 4 to the power of -3. She only raised z^8 to the power of -3 when it is supposed to affect both 4 and z^8

Answer:

The last one

Step-by-step explanation:

The answer for the first one is 4.47945205479, if you need to round that would be 4.5.

The answer for the second one is 20.4945454545, rounding will be 20.5.

The answer for the last one is 893.84, rounding will be 893.8.

If you need to round just remember 4 or less, will be rounded to 0, and 5 or more would be rounded to 10.

Answer:

-75

Step-by-step explanation:

Let us consider the first  odd number to be 'x'.

Thus:

According to the question, the sum of these three consecutive ODD numbers should be equal to -219

So,

x + x + 2 + x + 4 = -219

3x + 6 = -219

3x = -225

x = -75

Answer:

[tex]\frac{7}4[/tex]

Step-by-step explanation:

First, we need to find the slope, which is defined as the change in y over the change in x:

[tex]\frac{-5-(-1)}{3-(-4)} = \frac{-4}{7}[/tex]

To find a slope that's perpendicular to that, we just take the negative reciprocal of that slope, which is [tex]\frac{7}4[/tex].

20+3=23

23 is not less than 10

Answer:

10.75

Step-by-step explanation:

The cost of an adult ticket is £6 more than that of a child ticket, so will be shown by c+6.

Now, we are told that the cost of four child tickets and two adult tickets is £40.50, so we can put this in an equation and solve for c:

(c+6)+(c+6)+c+c+c+c=40.50

6c+12=40.50

6c=28.50

c=4.75

so, a childs ticket is 4.75

now to find the cost of an adult ticket you add 6,

4.75 + 6

= 10.75

Answer:

√64 = 8

Step-by-step explanation:

The Square root of 64 is 8

Square of ( +/-8) is 64. Since the negative numbers inside square root results in an imaginary number, so the square root must be positive and hence +8 is a square root of 64. The Answer is 8.

What is the simplest radical form of the square root of 64?

The "simplest radical form" of √64 is √26 if we define "simplest form" as a radical of a prime to an integer power.

Answer:

[tex]1.45x+0.65y\leq 200[/tex]

Here, [tex]x[/tex] denotes the number of roses used for a school celebration and [tex]y[/tex] denotes the number of carnations used for a school celebration.

Step-by-step explanation:

Let [tex]x[/tex] denotes the number of roses used for a school celebration and [tex]y[/tex] denotes the number of carnations used for a school celebration.

Cost of 1 rose = $1.45

Cost of [tex]x[/tex] roses = [tex]\$1.45x[/tex]

Cost of 1 carnation = $0.65

Cost of [tex]y[/tex] roses = [tex]\$0.65y[/tex]

Total cost spend on flowers = [tex]1.45x+0.65y[/tex]

Total amount with Jaida = $200

So,

the inequality to represent the cost constraint is [tex]1.45x+0.65y\leq 200[/tex]

This equation can be written as :-

= 6 + 4x = x + 15

= 4x+6=x+15

= 4x + 6 − x = x + 15 − x

= 3x + 6 = 15

= 3x + 6 − 6 = 15 − 6

= 3x = 9

= 3 x 3 = 9

= x = 9 ÷ 3

= x = 3

Using this , let us solve the equation :-

= 6 + 4 × 3 = 3 + 15

= 6 + 12 = 3 + 15

= 18 = 18

Therefore , 6 + 4x = x + 15 = 18 ( x = 3 ) .

Answer:

-303.11 -175

Step-by-step explanation:

The jet has a speed of magnitude 350 miles/hour and travelling in a direction of 210°. Hence the jet can be represented with |r| = 350, θ = 210°.

The component form of the vector has both the x component (horizontal component) and the y component (vertical component) Therefore:

The horizontal component = [tex]r_x=|r|cos\theta=350*cos(210^o)= -303.11[/tex]

The vertical component = [tex]r_y=|r|sin\theta=350*sin(210^o)= -175[/tex]

AB = 2

Step-by-step explanation:

Using the secant- secant theorem, that is

PA × PB = PD × PC , substitute values

10(10 + AB) = 8(8 + 7)

100 + 10AB = 8 × 15 = 120 ( subtract 100 from both sides )

10AB = 20 ( divide both sides by 10 )

AB = 2

Answer:

  see attached

Step-by-step explanation:

Most of this exercise is looking at different ways to identify the slope of the line. The first attachment shows the corresponding "run" (horizontal change)  and "rise" (vertical change) between the marked points.

In your diagram, these values (run=1, rise=-3) are filled in 3 places. At the top, the changes are described in words. On the left, they are described as "rise" and "run" with numbers. At the bottom left, these same numbers are described by ∆y and ∆x.

The calculation at the right shows the differences between y (numerator) and x (denominator) coordinates. This is how you compute the slope from the coordinates of two points.

If you draw a line through the two points, you find it intersects the y-axis at y=4. This is the y-intercept that gets filled in at the bottom. (The y-intercept here is 1 left and 3 up from the point (1, 1).)
