Answer:
4
Step-by-step explanation:
The slope for the given equation is 4.
Answer:
4
Step-by-step explanation:
Since the equation is written in y=mx+b form, we know that M is the value of the slope.
Since y=4x+5 is in slope intercept form, 5 would be (0,5) for y-Intercept
Which polygon has perpendicular sides?
Answer: A
Step-by-step explanation: a rectangle as 90 degree angles also known as a right angle. You can tell by the little boxes on the sides.
Find a line that is perpendicular to y = 2/5x-1 that goes through (3,6)
Answer:
[tex]\sf y=-\frac{5}{2}x+\frac{27}{2}[/tex]
Step-by-step explanation:
given equation:
[tex]\sf y = \frac{2}{5} x -1[/tex]
using the formula: y = mx + b
Here, we can determine 2/5 is the slope
if perpendicular: -1/m → -1/2/5 → -5/2
using the formula:
[tex]\sf y - y1 = m ( x - x1)[/tex]
[tex]\sf y - 6 = -\frac{5}{2} ( x - 3 )[/tex]
[tex]\sf y - 6 = -\frac{5}{2} x - \frac{15}{2}[/tex]
[tex]\sf y = -\frac{5}{2} x + \frac{15}{2} +6[/tex]
[tex]\sf y=-\frac{5}{2}x+\frac{27}{2}[/tex]

f(5) = ?
»f(x) = 9(9 + x)(10)
subtitute x = 2 for f(x).
»f(5) = 9(9 + 5)(10)
»f(5) = 9(14)(10)
»f(5) = 1,260✅
Answer:
1260
Step-by-step explanation:
f(5) = 9(9 + 5)(10)
= 9(14)(10)
= 126(10)
= 1260
Sam needs

cup mashed
strawberries for a recipe. He wants to find whether he needs
more bananas or more strawberries. How can he write 5_
6
and
3_
4
as a pair of fractions with a common denominator?
Answer:
He needs more bananas. ([tex]\frac{10}{12}+\frac{9}{12}[/tex])
Step-by-step explanation:
Find the least common multiple for both denominators.
For 6 and 4 in the denominators, their L.C.M is 12.
Cup of mashed bananas:
Multiply both the numerator and denominator by 2.
[tex]\frac{5}{6} = \frac{10}{12}[/tex]
Cup of mashed strawberries:
Multiply both the numerator and denominator by 3.
[tex]\frac{3}{4} = \frac{9}{12}[/tex]
Since the denominators are now the same, we can compare them in the same ratio.
[tex]\frac{10}{12} > \frac{9}{12}[/tex]
Therefore he needs [tex]\frac{1}{12}[/tex] more mashed bananas than mashed strawberries.

The Equation of L1, is y=5x+1
The Equation of L2, is 2y-10x+3=0
Show that these two lines are parallel
Parallel lines are lines that have equal slope
It is true that the two lines are parallel
How to show that the lines are parallel
The equations of the two lines are given as:
y = 5x + 1 and 2y - 10x + 3 = 0
Both equations are linear equations, and a linear equation is represented as:
y = mx + b
Where m represents the slope.
For equation L1, the slope is:
m = 5
For equation L2, we have:
[tex]2y - 10x + 3 = 0[/tex]
Divide through by 2
[tex]y - 5x + 1.5 = 0[/tex]
Make y the subject
[tex]y = 5x - 1.5[/tex]
This means that the slope of equation L2 is also 5
When the slopes are equal, then the lines are parallel
Hence, the two lines are parallel

what is the lateral surface area area of a cuboid
Answer:
Lateral surface area - The sum of surface areas of all sides except the top and bottom face of solid is defined as the lateral surface area of a solid. So the lateral surface area (L.S.A) of the cuboid is = 2(lh+bh)=2h(l+b)
Answer:
Lateral surface area of a cuboid = 2h(l + w)
where w = width, l = length and h = height
Step-by-step explanation:
Lateral Surface Area = Total Surface Area - Area of top and bottom faces
Let w = width
Let l = length
Let h = height
Lateral Surface Area = 2(lw + wh + lh) - (2 × l × w)
= 2lw + 2wh + 2lh - 2lw
= 2lh + 2wh
= 2h(l + w)

Draw a line representing the "rise" and a line representing the "run" of the line. State
the slope of the line in simplest form.
Solution:
Rise and run stated in graph below.
To find the slope of the line, we need to use the formula "Rise/Run".
Looking at the graph, we can tell that
The rise is 3 unitsThe run is 12 unitsWhen rise/run used:
Rise/Run = 3/12 = 1/4Thus, the slope is 1/4.

Prepare an amortization schedule for a three-year loan of $57,000. The interest rate is 8 percent per year, and the loan calls for equal annual payments. How much interest is paid in the third year? How much total interest is paid over the life of the loan?
To repay this loan in three years we must make annual payments of $23,560.
How to calculate how much we should pay annually?To calculate the payments that we must make each year, taking into account the 8% interest, we must carry out the following operations:
$57,000 ÷ 3 = 19,000To calculate the interest equivalent to 8%:
$57,000 ÷ 100 = $570$570 × 8% = $4,560So, to calculate the total per year that we must pay, we must add both values:
$19,000 + $4,560 = $23,560Finally, to know how much we pay in total for the interest on the loan, we multiply the value of the interest by the years that the loan lasted:
$4,560 × 3 = $13,680

0.15(w+2)=0.3+0.2w I need help
Answer: w=0
Step-by-step explanation:
Step 1 Solve by distributing 0.15w+0.15\cdot2=0.3+0.2w
Simplify the arithmetic 0.15w+0.3=0.3+0.2w
Step 2 Subtract 0.2w from both sides 0.15w+0.3-0.2w=0.3+0.2~w-0.2w
Group like terms: 0.15w-0.2w+0.3=0.3+0.2w-0.2w Simplify the arithmetic -0.05w+0.3=0.3+0.2w-0.2w Group like terms -0.05w+0.3=0.2w-0.2w+0.3 Simplify the arithmetic -0.05w+0.3=0.3
Step 3 Subtract 0.3 from both sides -0.05w+0.3-0.3=0.3-0.3 Simplify the arithmetic -0.05w=0.3-0.3 Simplify the arithmetic -0.05w=0 Isolate the X
then equals w=0

A survey found that women spend on average $146.21 on beauty products during the summer months. Assume the standard deviation is $29.44. Find the percentage of women who spend less than $160.00. Assume the variable is normally distributed.
see the attached image.
The percentage of women who spend less than $160.00 is 68.03%.
What is Standard Deviation?The term "standard deviation" refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
Given:
standard deviation = $29.44.
A survey found that women spend on average $146.21
so, the z- score
= 160 - 146.21 / 29.44
= 13.79/ 29.44
= 0.4684
Now, P( z< 0.4684)= 0.6803= 68.03%
