7. Solve the equation y – 11 = -4.
8. Evaluate the expression a + b when a = 2.5 and b = -10.8.
9. Draw the number line graph of 0.4.
10. Insert < or > to make this statement true: -1.8 -2.5
Answer:
9, 7,-8.3,>
Step-by-step explanation:
5)-3 is marked exactly 3 units to the left of origin 0.
(since negative sign we mark on left of 0)
6) |-9| = absolute value of 9 = 9
7) y-11=-4
Add 11 to both the sides
WE get y =7 is the solution
8) a + b when a = 2.5 and b = -10.8.
= 2.5+(-10.8) = -(10.8-2.5) = -8.3
9) 0.4 is positive hence lies to the right of origin.
Partition the space between 0 and 1 into 10 equal subparts and mark 4th subdivision to get 0.4
10) -1.8>-2.5

Write an equation in slope-intercept form for the line that is parallel to y = −7x − 8 and that passes through the point (7, −8).
A. y = −7x − 56
B. y=1/7x-9
c. y = −7x + 41
D. y=1/7x-8
The slope intercept from of equation is y= -7x + 41.
what is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given:
A line that passes through points (7, −8). and parallel to y = −7x − 8
Now, the slope of given parallel line is -7 and slope of line which is to parallel also of have the same slope.
So, slope of parallel line = -7
Now, using slope intercept form
y -a = m( x- b)
y - (-8)= (-7)(x-7)
y +8 = -7x + 49
y= -7x + 71
Hence, the slope intercept from of equation is y= -7x + 41

If the ratio of silver nail paints to golden paints is 4 to 2 and there are total 60 nail paints, how many of them are golden?
20,
So, there are 6 total parts,
X = 60/6
Each X = 10
So, 10*2 = 20
20 of them are golden.
To determine the number of golden nail paints, the total nail paints (60) are divided by the sum of the ratio parts (3), resulting in 20 nail paints per part. Multiplying the part for golden paints (1) by 20 gives us 20 golden nail paints.
The ratio of silver nail paints to golden paints is given as 4 to 2, which simplifies to a ratio of 2 to 1. This means that for every 2 silver nail paints, there is 1 golden nail paint. If there are a total of 60 nail paints, we need to determine how many of them are golden. To find out, we divide the total number of nail paints by the sum of the ratio parts (2 + 1 = 3 parts). Hence, each part represents 20 nail paints (60 ÷ 3).
To calculate the number of golden nail paints, we then multiply the number of parts for golden paints (which is 1 part) by the nail paints per part, so we get 20 x 1 = 20 golden nail paints.

On which intervals is the function increasing?
Indicate intervals on the x-axis using the Ray tool for intervals that extend to infinity and the Segment tool for bounded intervals.
Graph a ray by selecting the endpoint followed by a point on the ray. Graph a segment by selecting an endpoint followed by the other endpoint.
Answer:
Refer below
Step-by-step explanation:
A function is said to be increasing if y increases whenever x increases and y decreases whenever x decreases.
A function is decreasing if y increases when x decreases or vice versa.
Hence from the graph we find that when the curve is going up when we move to right the function is increasing otherwise decreasing.
f(x) attains its extreme values at x = -8, -3, 2 and 6
Left of -8 we find f(x) is increasing.
ie.(-infty, -8) increases, (-8,-3)decreases, (-3,2) increases, (2,6) decreases and (6,infty) increases
To consolidate increasing in (-infty, -8)U(-3,2)U(6,infty)

A car uses 7litres of pétrole to coker 28km . How many litres of pétrole does hé use to coker 64km
28/7=4km is car journey covered by car in 1l
64/4=16l
The car would use 16 liters of petrol to cover 64 km.
Explanation:To find out how many liters of petrol the car uses to cover 64 km, we can set up a proportion using the given information. Since the car uses 7 liters of petrol to cover 28 km, we can say that the fuel consumption rate is 7 liters per 28 km. To find out the fuel consumption rate for 64 km, we can set up the proportion:
7 liters / 28 km = x liters / 64 km
Cross-multiplying, we get 28x = 7 * 64.
Dividing both sides by 28, we get x = 7 * 64 / 28 = 16 liters. Therefore, the car would use 16 liters of petrol to cover 64 km.

1/25(20-t)=4/25t-3/5
Remark
Multiply both sides of the equation by 25. Then you have an equation that you have already done probably.
Step One
Multiply both sides of the equation by 25
1 * (20 - t) = 4t - (3/5) * 25 Every part of the equation must be multiplied by 25
(20 - t) = 4t - 75/5 3*25/5 = 75/5
20 - t = 4t - 15 Add t to both sides
20 - t + t =4t + t - 15 Combine like terms
20 = 5t - 15 Add 15 to both sides
20 + 15 = 5t - 15 + 15 Combine like terms
35 = 5t Divide by 5
35/5 = 5t/5 Switch sides

Yes; the similarity ratio is 5:6.
Answer:
It is yes the similarity ratio is 3:4.
Step-by-step explanation:
Answer:
Option 2 is correct that is NO ; The triangles are not similar.
Step-by-step explanation:
Given: Measurements of the sides of triangle.
Say sides of triangle 1 = 3 , 5 , 6
Sides of triangle 2 = 4 , 6 , 8
We have to find if triangles are similar or not and if they are similar then to find their ratio.
Since, We are given with only sides of the triangle.
Then if they are similar then they will be by Side-Side-Side similarity criteria.
Here, Two triangles are said to be similar by Side-Side-Side Criteria if ratio of their sides are equal.
But clearly from given values , all ratios are not equal.

What is the domain of the function represented by the mapping diagram below?
Answer:
Option C
{-1,3,5}
Step-by-step explanation:
A mapping is a subset of ordered pair (x,y) where x belongs to first set and y belongs to second set.
Hence a mapping is a subset of cartesian product AXB.
Here A = {-2,1,3,5} and
B = {2,4,6,8}
Ordered pair given by the mapping is
(-2,1) (3,6) and (5,8)
In other words, -2 is mapped on to 1, 3 to 6 and 5 to 8
Domain = set of elements in the I set which are mapped
= {-1,3,5}
