Dmitry [639]2 years ago
4 0

Step-by-step explanation:

You can let me know, but i dont think -3x² is supposed to be squared in this question because then it would make it unsolvable.

5x-15

can be simplified to 5(x-3)

x²-3x

can be simplified to x(x-3)

Then u rewrite it (5 + x)(x - 3)

there are a 100 student in a garde 79 students has honors what deciaml best represents the amount that the student honors
gogolik [260]

There are 100 students. In the 100 students, 79 of them have honors. To find the decimal form for the students who have honors, divide the total amount of students with honors with the total amount of students.

\frac{Honors}{Total} = \frac{79}{100}

Divide 79 by 100

79 \div 100 = 0.79

Your answer is 0.79

Can someone help me please and thank you
Veronika [31]

Find the ratio of the two similar sides that both dimensions are given.

The smaller triangle aide that is 4 units is the similar side of the larger triangle given as 8 units.

8 / 4 =2, this means the larger triangle is 2 times the size of the smaller triangle, which also means the smaller triangle is 1/2 the size of the larger triangle.


X on the smaller triangle is 1/2 11 units which equals 5.5 units.

Y is 2 times 3, which equals 6 units.

x = 5.5

y = 6

Given f(x) is a linear function with slope 3 and y-intercept -5, what is the equation of f(x) in standard form?
lawyer [7]

The standard form:

Ax+By=C

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

We have m = 3 and b = -5.

Substitute:

y=3x-5         subtract 3x from both sides

-3x+y=-5             change the signs

3x-y=5
