I Don't Really Understand This Problem

Answers

Answer 1

Answer:

Step-by-step explanation:

So what you need to do is mark to points on the graph. For example (9,4) and (18,8). The run would be 9 and the rise would be 4. Gradient = rise/run which is 4/9. So that's the gradient. Now it asks for the equation. The formula for an equation is y=mx+c m= the gradient and c = the y-intercept (the y intercept is where the line meets the axis so it would be 0) so the answer is: y=4/9x+0.

Hope this helped !!

Scale factor is 7

x = 3

The second one

Scale factor is 9

x = 99

Step-by-step explanation:

The first one

You can find out by dividing 49 by 7 which is 7

to find x =  21 divided by 7 is 3

The second one

You can find out by dividing 162 by 18 which is 9

to find x =  11 multiplied by 9 (since it is "opposite") is 99

What will be the result of substituting 2 for x in both expressions below? One-half x + 4 x + 6 minus one-half x minus 2 Both expressions equal 5 when substituting 2 for x because the expressions are equivalent. Both expressions equal 6 when substituting 2 for x because the expressions are equivalent. One expression equals 5 when substituting 2 for x, and the other equals 2 because the expressions are not equivalent. One expression equals 6 when substituting 2 for x, and the other equals 2 because the expressions are not equivalent.

Answers

Replace x with 2 and solve each equation:

1/2(2) + 4 = 1 + 4 = 5

2+ 6 -1/2(2) -2 = 8-3 = 5

The answer is:

both expressions equal 5 when substituting 2 for x because the expressions are equivalent.

What is m
Look at the image above

Answers

Answer:

m∠F = 90°

Step-by-step explanation:

By the property of a kite,

"One pair of the opposite angles are congruent"

m∠E ≅ m∠G

m∠E = m∠G = 113°

Sum of the interior angles of a polygon = (n - 2) × 180°

Here, n = number of sides of the polygon

For a kite, n = 4

Therefore, sum of the interior angles of the given kite = (4 - 2) × 180°                                                                          

                                                                                          = 360°

Therefore, m∠E + m∠F + m∠G + m∠H = 360°

113° + m∠F + 113° + 44° = 360°

m∠F = 360° - 270°

m∠F = 90°

Now find the measure of ∠YOZ. Which angle relationship did you use?

Answers

The angular measure of ∠YOZ is : 60° and the angular relationship used is vertically opposite angles(VOA).

How are angles formed?

Angles are formed when two lines meet. this could be a direct intersection or an intersection between two parallel lines and a transversal.

Angles can be acute, obtuse, or reflex.

Analysis:

Given data:

∠VOX = 90°

∠WOX = 30°

∠WOX + ∠VOW = ∠VOX

30° + ∠VOW = 90°( the two angles are complementary that is they sum up to 90°)

∠VOW = 90 - 30 = 60°

∠VOW  = ∠YOZ ( vertically opposite angles are equal)

∠YOZ = 60°.

in conclusion, the angular measure of ∠YOZ = 60° and the angular relationship used is vertically opposite angles.

Stefani received a loan for $2,000 and now has acquired $720 in interest. If she pays an annual interest of 4.5% on the amount borrowed. how much time has elapsed since Stefani received the loan?

Answers

Answer:

8 years.

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4.5%/100 = 0.045 per year,

then, solving our equation

t = 720 / ( 2000 × 0.045 ) = 8

t = 8 years

The time required to

accumulate simple interest of $ 720.00

from a principal of $ 2,000.00

at an interest rate of 4.5% per year

is 8 years.
