Answer:

thequantity in column b is greater

Step-by-step explanation:

7a+b=33......(1)

3a-b=7.........(2)

(1)+(2)

7a+b+3a-b=33+7

10a+b-b=40

10a=40

a=4

in equation (1)

7*4+b=33

28+b=33

b=33-28

b=5

b>a

If sin 0 = 15/17 use pythagorean identity to find cos 0

Inga [223]

Hello :
sin<span>θ = 15/17
</span> use pythagorean identity : cos²θ +sin² θ = 1
cos²θ = 1 - sin² θ
cos²θ = 1-(15/17)²
cos²θ = 1- 225/289
cos²θ = 64/289
cos²θ = (8/17)²
cosθ = 8/17 or -8/17

Find g (a + 1 ), if g(x)=5x-3

nordsb [41]

Answer:

g(a+1)=5a+2

Step-by-step explanation:

so (a+1) is the value of x

you can write it like this:

x=a+1

using substitution, we can swap out all 'x's for 'a+1's. like so;

g(a+1)=5(a+1)-3 -- given

=5a+5-3 -- distribute

=5a+2 -- simplify!

Hope i helped! have a great day! please mark brainliest!!

How much sugar syrup would you get by Making 5% sugar syrup using 6g sugar?

kherson [118]

Answer: 120 grams.

Step-by-step explanation:

Let x be the amount of sugar syrup made by 5% sugar syrup using 6g sugar.

Also, 5% =0.05

Therefore, 5% sugar syrup =5% of x = 0.05x

According to the question, we have

$0.05x=6\\\text{Divide 0.05 on the both sides we get}\\\Rightarrow\ x=\frac{6}{0.05}\\\Rightarrow\ x=\frac{600}{5}\\\Rightarrow\ x=120$

Hence, 120 grams sugar syrup is made by 5% sugar syrup of 6g sugar.

Find the equation of the line that passes through he points (2,6) and (-2,4)

stepan [7]

First Find slope by using $\frac{y2-y1}{x2-x1}$

$\frac{4-6}{-2-2} = \frac{-2}{-4} = \frac{1}{2}$

Now use point Slope form to find the equation of the line (y-y₁)=m(x-x₁)
(y-6)= $\frac{1}{2}$ (x-2)
y-6= $\frac{1}{2} x-1$
y= $\frac{1}{2} x+5$ is your equation
