Substituting the given values of X into the function, the value of f(3) - f(4) is 2
Given the function :
f(x) = - 2x + 3f(3) = - 2(3) + 3
f(3) = - 6 + 3 = - 3
For X = 4 :
f(4) = - 2(4) + 3
f(4) = - 8 + 3 = - 5
f(3) - f(4) = - 3 - (-5)
f(3) - f(4) = - 3 + 5 = 2
Therefore, the value of f(3) - f(4) is 2

If the measures of two angles of a triangle are 87 and 17 , what is the measure of the third angle
Answer:
76 degrees
Step-by-step explanation:
The total of the three angles in a triangle should equal 180 degrees. So to find the third angle, subtract the two given angles from 180
180 - 87 = 93
93 - 17 = 76
The third angle is 76 degrees because then all angles will add up to 180

Sharon is planning a holiday for 4 people for 7 days
Here are the costs for the holiday for each person
Travel-£130 hotel-£60 for each day spending money-£350
Work out the total cost of the holiday for 4 people for 7 days
Answer:
3600
Step-by-step explanation:
Each PERSON cost:
Travel cost 130 (assume for whole 7 days since per day is not written)
Hotel 60 per day (so 7 days = 60 * 7 = 420)
Money Spend 350 (assume for whole 7 days since per day is not written)
-------------------------------------------------------------------------------------------------------------
Now, that sums to:
130 + 420 + 350 = £900 [each person for whole 7 days]
Now, there are 4 person, so total cost of whole group (4 persons):
900 * 4 = £ 3600

Proof:
∠1 = ∠ADB
∠2 = ∠DBC
∠3 = exterior angle adjacent to angle D B C.
Statement Reason
∠2 is supplementary to ∠3 Linear pairs
m∠2+m∠3=180° Definition of supplementary angles
Alternative interior angles
m∠1+m∠3=180° Substitute property of equality

A line that passes through the point (x,y), with a y-intercept of b and a slope of m, can be represented by the equation y = mx + b.
A line is drawn on the coordinate plane that passes through the point (10,1) and has a slope of -0.5. The y-intercept of the line is.
HELP!!!!
The equation of a line passes through the point (10,1) and has a slope of
- 0.5 is y = - 0.5x + b.
What is slope?The slope is the rate of change of the y-axis with respect to the x-axis.
The equation of a line in slope-intercept form is y = mx + b, where
slope = m and y-intercept = b.
We know the greater the absolute value of a slope is the more steeper is its graph or rate of change is large.
Yes, A line that passes through the point (x, y), with a y-intercept of b and a slope of m, can be represented by the equation y = mx + b.
Now, A line is drawn on the coordinate plane that passes through the point (10, 1) and has a slope of - 0.5.
Therefore, 1 = - 0.5(10) + b.
1 = - 5 + b.
b = 6.
And hence equation of the required line is,
y = - 0.5x + 6.

Evaluate ab for a = 2 3/4 and b = 4/5.
Rewrite a as an improper fraction:
2 3/4 = 11/4
Now you have 11/4 x 4/5
Multiply the two top numbers together and the two bottom numbers together.
11x4 / 4x5 = 44/20 now rewrite as 2 4/20 which can simplify to 2 1/5
Write the absolute value equation that has these two solutions x= (-8,22)
Answer:

Step-by-step explanation:
9a = b^3 + 4H
How do you solve for a
Ok, to solve for (a) you need to get it alone. So divide 9 by all.
9a/9 = b^3/9 + 4H/9
Then your left with your equation, which is
a = b^3/9 + 4H/9
